    [0001] The invention relates to an apparatus and method for forming a substantially smooth continuous material. Especially, it relates to an apparatus and method for forming a substantially smooth continuous material used in the manufacture of aerosol generating articles and smoking articles.
    [0002] Aerosol generating articles or components thereof, such as filter plugs or tobacco plugs, may be manufactured from at least a partially continuous and substantially smooth material, such as paper web, tobacco or plastic. Due to the special materials used to produce these tampons, some processing steps in a processing line can provide additional challenges when dealing with such wefts. For example, some plastic materials, eg polylactic acid webs, tend to be electrostatically charged and to be heated after using the web. This results in an irregular folding, for example, in a taper of the weft, reducing the reproducibility of the products to be manufactured by the weft.
    [0003] Thus, there is a need for an apparatus and method for forming the substantially smooth continuous material. Especially, there is a need for an apparatus and method for forming the substantially smooth continuous material, wherein the substantially smooth continuous material can be used in the production of aerosol generating articles or smoking articles.
    [0004] In accordance with a first aspect of the present invention, there is provided an apparatus for forming the substantially smooth continuous material. Preferably, the substantially smooth continuous material will be used in the manufacture of smoking articles or consumer products as used in electronic smoking devices. The apparatus comprises a forming device for joining the substantially smooth continuous material transverse to a longitudinal direction of the continuous material to form a joined continuous material. The apparatus further comprises a cooling device for cooling the joined continuous material. The forming device and the cooling device are combined so as to immediately cool the joined continuous material. Immediately cooling the joined continuous material is understood herein as cooling the substantially smooth continuous material at the same time as joining the substantially smooth continuous material or immediately after the substantially smooth continuous material is joined. To achieve this immediate cooling, the cooling device can be integrated into the forming device. Thereby, the joined continuous material is cooled at the same time as it is joined in the forming device. The cooling device may also be arranged close to the forming device and downstream of the forming device when viewed in a direction of conveying the substantially smooth continuous material or the joined continuous material. In such embodiments, preferably, the joined continuous material is immediately cooled after being joined in the forming device.
    [0005] Throughout the specification, the term "cooling" is used to refer to an active step to limit, maintain or reduce the temperature of substantially smooth continuous material or an element that is in contact with substantially smooth continuous material or both, thus preventing further rise in temperature of the substantially smooth continuous material.
    [0006] The terms "downstream" and "upstream" are used in this document in view of the conveying direction of the substantially smooth continuous material in the apparatus or in the individual elements of the apparatus.
    [0007] Cooling the material in or by a cooling device at the same time as the material is or has just been joined can prevent or reduce heating of the material after joining or reduce the heat distribution in the material. For example, heating can be caused by friction, for example while the web of material is being joined in the forming device. Excessive heating can change the specification of a material. In particular, materials with low glass transition temperatures or low melting temperatures or both can be sticky or can at least partially melt after being heated. If said material with altered characteristics is joined or formed, for example, in a column format, individual folds can join or merge. Thereby, for example, a drag resistance (RTD) or a plug formed by the material may be different from an intended value for the RTD and may in particular be non-reproducible. In addition, a partially melted or sticky material can stick to parts of the appliance. This may result in the unit becoming blocked and may dislodge or damage the material. This can be avoided by providing a cooling device by which the material can be cooled, preferably not exceeding a critical temperature. In addition, the tensile strength of the material can be reduced by heating. This may require reducing the speed of the machine to prevent material breakage, or it may cause the machine to stall and start to wear out due to material breakage with reduced tensile strength. Therefore, cooling is particularly advantageous for materials with a low glass transition temperature or low melting temperature, for example a polylactic acid web. At the glass transition temperature or transformation temperature, a solid material changes from the flexible-elastic state and the solid material becomes a sticky and pasty molten material. For example, an amorphous, semi-crystalline plastic material can become tacky and can undergo changes in its stability. A transition to the flexible-elastic state or yield variation is continuous. At the glass transition temperature, the material does not undergo a phase transition. Thus, the glass transition temperature is not related to an exact temperature, but to a temperature variation.
    [0008] A substantially smooth continuous material, as used herein, may be a web of a material, such as a web of paper, tobacco, or plastic, which may be used in the manufacture of smoking articles or aerosol generating articles for electronic devices. to smoke. Preferably, the substantially smooth continuous material is a continuous sheet of polylactic acid. Preferably, the substantially smooth continuous material is formed into a continuous column for future fabrication of individual plugs. The substantially smooth continuous material may have been preheated before being formed in the apparatus according to the invention. A pre-treatment can be, for example, crimping or embossing or both.
    [0009] The term "join" is used throughout the specification to refer to a reduction in the width of substantially smooth continuous material. By joining, the continuous material is reduced in a lateral direction of the material, thus transverse to the longitudinal direction and direction of transport of the material. A joint may, for example, be a longitudinal rib, a material supply with an overlapping longitudinal corrugation structure, a joint, a compression, a taper, a column formation of the material, or combinations of the aforementioned processes. A joint includes a reduction in the width of the substantially smooth continuous material, for example, by simply compressing the continuous material against a central longitudinal axis of the continuous material. A joint also includes a reduction in width by providing a microstructure and a macrostructure to the continuous material, for example, small crimps with an amplitude around the thickness of the material and transverse undulations with an amplitude of 10 times the thickness of the material. The material required to form the structure results in a reduced lateral extent of the continuous material. A join can be performed continuously or in stages. A union can be performed on one or several forming devices. Typically, reducing the width of the material results in an increase in the extent of the material in another dimension, e.g. normal to the web of substantially smooth continuous material. However, in some embodiments, the material may be compressible in itself, for example, a mesh or sponge-like material. In these substantially smooth continuous material embodiments, a reduction in the web width of the substantially smooth continuous material also or almost always results in an increase in material density.
    [00010] A bonded material, as used in this document, can be a partially bonded material or a final bonded material. Partially bonded material has a reduced width compared to the substantially smooth continuous material as supplied to the apparatus according to the invention. The partially bonded material may also have a reduced width compared to a partially bonded material that has already passed through a previous forming device. Partially bonded material has a width greater than the width of a final shape of continuous material. Preferably, a final shape is a column shape.
    [00011] Cooling can be achieved, for example, by cooling an element of the cooling device and by direct contact of the cooling element, for example, having a contact surface with continuous material. Cooling through a cooling element also supports a joining or forming step. For example, the cooling element or a contacting surface of the cooling element may comprise a shape for forming the continuous material in accordance with this shape to retain the continuous material in a specific shape. Cooling, for example, can also be integrated into the forming device. A forming device also serves as a cooling device.
    [00012] Cooling a cooling element can, for example, be achieved by providing a cooling medium within or through the cooling device. A cooling medium can, for example, be a cooling gas or cooling liquid, such as air or water. Continuous material cooling can also be achieved by direct contact with the cooling medium, for example a gas stream. Direct contact with the cooling medium can advantageously be provided, for example where space is limited or where mechanical contact with the continuous material will be avoided. Direct contact with a cooling medium can also be provided where an extent of cooling, eg changing cooling temperatures will change rapidly. Direct cooling with a fluid cooling medium, e.g. air, preferably creates a fluid cushion, e.g. an air cushion, between the substantially smooth continuous material and a corresponding conveyor element, so that at the same time, the substantially smooth continuous material is cooled and the friction between the transport element along the substantially smooth continuous material conveying path is reduced, so that heating of the substantially smooth continuous material by friction is avoided or reduced.
    [00013] Alternatively, or in addition, the cooling medium may be in the form of a Peltier element or a surface that is in contact with a Peltier element. A Peltier element has the advantage that little or no exhaustible cooling medium, for example air, needs to be supplied to the cooling zone, thereby simplifying the supply and removal of said additional exhaustible cooling medium.
    [00014] Preferably, the temperature of a cooling medium is chosen so that the cooled continuous material does not exceed a predefined high or maximum temperature. Preferably, a cooling is also adapted so that a cooling medium is not reduced to a predefined low or minimum temperature. At very low temperatures, a cooling circuit may possibly not demonstrate optimal performance. In addition, a continuous material may become brittle or may inadvertently break in handling if cooled to low temperatures. Preferably, temperatures of a cooling medium are in the range of about 5 to 35 degrees Celsius, preferably between 10 degrees Celsius and 25 degrees Celsius.
    [00015] The apparatus according to the invention may comprise a forming device with one or more static forming elements, one or more dynamic forming elements or a combination of static or dynamic forming elements.
    [00016] According to one aspect of the apparatus according to the invention, the forming device comprises at least one static forming element. In this context, static means that the forming elements are stationary with respect to a substantially smooth continuous material transport direction. In some preferred embodiments, the apparatus comprises only static forming elements, these embodiments of the apparatus do not comprise dynamic forming elements as will be described later in the document. With static forming elements, the substantially smooth continuous material or also a partially bonded material is formed by passing the static forming element. This can facilitate an installation due to the override of the device's moving parts. This can advantageously reduce wear on machine parts and maintenance.
    [00017] In some preferred embodiments, a static forming element is a pad tongue to form the substantially smooth continuous material into a column shape. The cooling device is arranged proximate an outlet opening of the padding tongue and comprises a contact surface for touching the joined web of material leaving the padding tongue. In general, in gaskets, friction is high between the material being formed and the inner walls of the gasket. Thus, cooling is provided immediately after formation of the column in the trim tongue to stop or prevent material changes caused by frictional heating.
    [00018] Preferably, the contact surface of the cooling device contacts the joined or column molded material along a predefined length of the joined material. The mating surface may have a shape corresponding to the shape of the bonded material leaving the pad tongue. Preferably, the contact surface of the cooling device has a longitudinal concave shape, for example a tunnel shape which covers a portion over a predefined length of the joined material. Said tunnel-shaped contact surface of a cooling device also replaces an end portion of a trim tongue.
    [00019] The static forming element or an additional static forming element may be constructed as at least one structured surface, wherein the structure has a longitudinal extent in a substantially smooth continuous material transport direction. A continuous material is guided along the material structure and thus formed and joined in accordance with the structure. Preferably, the substantially smooth continuous material is successively joined in a direction transverse to a substantially smooth continuous material conveying direction as it passes between the structured surface of the static forming element and a counter element disposed opposite the structured surface. The counter element may have a substantially flat surface or a surface comprising a structure, preferably a structure corresponding to the surface structure of the forming element. Preferably, such corresponding structures can couple to each other. The substantially smooth continuous material can be cooled by the static forming element, i.e. while the continuous material passes along the structural surface of the static forming element.
    [00020] The structure of a surface of a static forming element may, for example, at a specific longitudinal position be the same over an entire width of the surface or may be different across the width of the surface (the surface width is seen in relative to the width of the continuous material). For example, the structure in a center of a forming element may be larger than in the lateral regions. Thereby, friction due to a lateral movement of the continuous material passing through this structure can be reduced. Thus, the heat production due to friction can also be reduced.
    [00021] Two or a series of static forming elements with a structured surface can also be supplied. Preferably, the static forming elements of a series are arranged along the conveying direction of the continuous material. A distance between the individual forming elements can vary and can be selected according to a joining result to be obtained. In a series of static forming elements, the structures of the individual static forming elements can be different, for example with respect to a height or spacing of the structures of the forming elements. Dividing the forming section into individual assemblies can advantageously reduce the complexity of frame fabrication, in particular for curved and non-planar frame surfaces. Furthermore, advantageously, individual sections can be replaced as needed under wear as opposed to the need to replace the entire forming structure, reducing, for example, the cost for spare parts. Additionally, it may be sufficient to guide the web of substantially smooth continuous material during the forming step only between about 20 percent and about 50 percent of the length of a conveyor direction of the forming structure. In some embodiments, the forming structure comprises an upper structure and a corresponding lower structure and one of the upper and lower structure is provided only partially, for example, along between about 20 percent and about 50 percent of the length in one direction. transport of the forming structure as support points. This may also allow additional access to the web of substantially smooth continuous material within the forming structure, for example to allow a cooling means to reach the web of substantially smooth continuous material.
    [00022] As a general rule, whenever the term "about" is used in relation to a specific value throughout this application, it should be understood that this value following the term "about" does not have to be exactly the specific value due to technical considerations. However, the term "about" used in relation to a specific value should always be understood to include and also explicitly disclose the specific value after the term "about".
    [00023] One or a series of static forming elements with structured surfaces can, for example, be cooled by cooling the forming element. A material passing through the forming element(s) is automatically cooled after touching the cooled structured surface of the forming element. A cooling medium, such as a gas stream, may also be permitted in the continuous material, for example through openings in the structured surface of a forming element. Such a gas flow may also be provided to support a conveyance of the continuous material, for example, by forming an air cushion of the continuous material which can slide.
    [00024] According to another aspect of the apparatus according to the invention, the forming device comprises a dynamic forming element capable of carrying out a movement in a direction of transport of the substantially smooth continuous material.
    [00025] Dynamic forming elements allow them to be moved in the same direction according to the continuous material. Thereby, a relative movement between the continuous material and the forming element is reduced. This can reduce friction and friction-related heat production.
    [00026] In some preferred embodiments, a dynamic forming element comprises at least a former roll part, wherein the rollers of the former roll pair are rotatable in a substantially smooth continuous material transport direction. The forming rolls have structures arranged circumferentially on a periphery of the forming rolls to form the continuous material passing between the pair of rolls. The rotational axis of the pair of forming rolls is arranged along the width of the continuous material so that the structures are aligned in the direction of transport of the continuous material. Preferably, the circumferentially arranged structures have heights that decrease from a central part of the forming rolls (central portion of the continuous material) to a side part of the rollers (side portion of the continuous material). Thereby friction and heating are produced due to a continuous lateral movement of the material. The forming rolls can also be cooled.
    [00027] A dynamic forming element may comprise a series of pairs of forming rolls. The pairs of forming rollers in the series are arranged in parallel. Structures on the circumference of the forming rolls may be different between the different pairs of forming rolls in the series of forming roll pairs. Preferably, different structures on the forming rolls are adapted to a position of the forming rolls in the apparatus (upstream or downstream of a continuous material transport direction) and to a joining extent of the continuous material.
    [00028] The forming device may comprise a conveyor unit to form the substantially smooth continuous material, preferably into a round shape. The transport unit comprises at least two dynamic forming elements arranged sequentially in the form of at least two union rollers with a rotating axis perpendicular to a continuous material transport direction. Preferably, the splicing rolls have a circumferentially shaped passage groove for moving the substantially smooth continuous material in the grooves and between each of the splicing rolls and an oppositely disposed guide element. At least two oppositely arranged joining rollers are arranged at a distance from each other along the conveying direction of the substantially smooth continuous material. A distance between the joining roller and guide element can be varied, for example, by a lateral displacement of the forming rollers or guide elements or by both. By means of such lateral displacement, a width reduction extent of the continuous material can be variably defined. This increases flexibility in adjusting the splicing rolls with respect to, for example, web width of substantially smooth continuous material. The width of the substantially smooth continuous material may differ between production runs, for example, due to different final densities of the joined substantially smooth continuous material. Furthermore, lateral guide elements are advantageous in aligning the web of substantially smooth continuous material in a transverse direction, for example to compensate for a transverse displacement of the material during production. The web of the substantially smooth continuous material may exhibit transverse displacement in particular after the step of structuring the substantially smooth continuous material, for example by crimping, which reduces the transverse stability of the web of the substantially smooth continuous material.
    [00029] Preferably, the grooves of at least two union rolls have a different shape. For example, the groove of a splicing roll arranged further downstream has a shape that may correspond to a final shape of the continuous material or substantially corresponds to a final shape of the continuous material. For example, if the final shape is a column shape, the groove of a splicing roll arranged further downstream may have a shape that is substantially circular, while the groove of a splicing roll disposed further upstream may have a shape that it's more oval.
    [00030] In a conveyor unit as described herein, a substantially smooth continuous material is formed and partially joined with and in accordance with the first splicing roll. The substantially smooth continuous material is further joined by the subsequently arranged splicing roll. With the conveyor unit, a substantially smooth continuous material can be molded sequentially and in stages into a final shape, preferably column shape. Dynamic joining rollers provide low friction, limiting heat output. In addition, the sequentially arranged joining rollers allow better control over the continuous material forming process. Thus, a bending of the continuous material can be done more reliably and reproducible products, eg with reproducible RTD, can be manufactured.
    [00031] Oppositely arranged guiding element or elements may be stationary. For example, guide elements arranged oppositely can be wall elements or a single wall element. Oppositely arranged guide elements can also be movable, for example they can also be in the form of union rollers with a groove. Preferably, each of the oppositely arranged guide elements or splicing rolls is provided with a groove having a shape corresponding to a shape of the groove of the oppositely arranged splicing roll.
    [00032] In some preferred embodiments, at least two splicing rollers are each elements of a pair of rollers. Each splicing roll of a pair of splicing rolls has a rotational axis perpendicular to a sheet material transport direction and has a circumferentially shaped passage groove for conveying the substantially smooth continuous material between the splicing rolls of a pair of union rollers and oppositely arranged grooves. Preferably, a distance from and between the pairs of splicing rolls or also between a splicing roll and its oppositely arranged guide element can be variable to define a length of a splice of a continuous material.
    [00033] Preferably, the forming device comprises at least two different dynamic forming elements which are arranged sequentially and at a distance from each other along the conveying direction of the substantially smooth continuous material. At least two different dynamic forming elements may, for example, each comprise a pair of forming rolls with structures arranged circumferentially on a periphery of the forming rolls. At least two subsequently arranged dynamic forming elements may, for example, also be part of a conveyor unit of the forming device to form the substantially smooth continuous material, preferably in round shape. At least two subsequently arranged dynamic forming elements are in the form of at least two joining rollers with a rotating axis perpendicular to a substantially smooth continuous material transport direction and with a circumferentially shaped passage groove.
    [00034] In order that the dynamic forming elements are different, for example, a groove of a joining roll arranged further upstream has a shape that is different from the shape of a groove of a joining roll arranged further downstream. Dynamic forming elements are different, e.g. they have a different forming structure or are arranged with respect to a direction or position of conveying the continuous material, such as to achieve a different bond to the smooth continuous material when the continuous material passes the first of at least two dynamic forming elements and the second of at least two dynamic forming elements. Advantageously, a different joint is a joint to a different extent, but can also be a joint in different sections over a width of continuous material, including provision of continuous material with a different joint structure.
    [00035] According to a further aspect of the apparatus according to the invention, the apparatus further comprises a splitting unit for creating an opening channel in the joined continuous material. The splitting unit comprises a splitting element which is relatively movably arranged in a conveying direction of the substantially smooth continuous material or bonded material, respectively. The dividing element is arranged to extend at least partially in the joined continuous material. The dynamic splitting unit again provides less friction than, for example, a static splitting element such as a splitting pawl. Thus, less heating is produced by the split unit with a moving split element.
    [00036] An opening channel created by the division unit, for example, serves for the introduction of an object, such as, for example, a capsule or line. An object introduced can, for example, serve for aromatization, coloring or filtration purposes. The splitting element can be additionally cooled.
    [00037] In some preferred embodiments of the splitting unit, the splitting unit comprises a pair of splitting rollers arranged in parallel and rotating in the direction of conveying the substantially smooth continuous material. The splitting roller pair defines a passage between the two splitting rollers of the splitting roller pair. The splitting element is a splitting disk disposed around the circumference of one of the splitting rollers of the splitting roller pair and extending into the passage. The continuous material passes through the passage formed between the splitting rolls.
    [00038] A division unit also serves as a training unit. For example, a passage between splitting rolls can be shaped according to a desired formation of the continuous material passing between the two splitting rolls. For example, the passage may be oval-shaped.
    [00039] A splitting unit, for example, can be arranged between two dynamic forming elements subsequently arranged, for example, between two joining rollers of a transport unit as described above. Thus, an object can be introduced into a partially bonded material. Partial join still allows insertion of an object, however partial join can also limit an object displacement introduced into continuous material. This allows for greater precision in aligning the object within the joined material. With the splicing roll subsequently arranged, the continuous material is further joined and the object is fixed to the material. If the split roller is cooled, its cooling action can support continuous material cooling after joining in the transport unit.
    [00040] In general, any static or dynamic forming element can be cooled to support reliable bonding and forming of the continuous material, in particular, material with low melting temperature or low glass transition temperature or both, a glass transition temperature low and a low melting temperature.
    [00041] One or more embodiments of the apparatus according to the invention may be arranged along a treatment line for the substantially smooth continuous material. In this regard, modalities with different forming devices and with different cooling devices can be combined. An apparatus may also comprise one or more forming devices disposed further downstream or upstream of a materials treatment line. The various forming devices may be arranged next to each other or may have one or several other material handling steps performed between the forming devices. Preferably, more than one forming device, preferably two to three forming devices as described herein are arranged along a treatment line. Forming devices with static forming elements can be combined with forming devices with dynamic forming elements. Static forming elements can be exchanged with dynamic forming elements according to the required materials treatment process. Forming devices combined with cooling devices, for example with cooled contact surfaces or cooled forming elements, can be combined with forming devices without cooling. Forming devices providing the continuous material with a structure can be combined with forming devices which press the continuous material together.
    [00042] In accordance with another aspect of the present invention, there is also provided a method of forming a substantially smooth continuous material. The method comprises the steps of providing a substantially smooth continuous material and joining the substantially smooth continuous material in a lateral direction to form a joined continuous material. The method further comprises the step of cooling a substantially smooth continuous material while joining the substantially smooth continuous material or immediately after joining the substantially smooth continuous material.
    [00043] The step of joining the substantially smooth continuous material may comprise successively joining the substantially smooth continuous material in a direction transverse to a transport direction of the material web. The joining step may be combined with the cooling step, for example, by cooling the substantially smooth continuous material while passing the substantially smooth continuous material along the structured surface of the static forming element.
    [00044] The joining step may comprise joining successively by passing the substantially smooth continuous material between at least one pair of rollers with structures arranged circumferentially. In this way, the structure of the forming rolls is superimposed on the continuous material. In another variant of the dynamic forming elements, the continuous material is joined in a lateral direction by guiding the material along different shapes of grooves arranged in the subsequently arranged joining rolls.
    [00045] The steps of joining and cooling the substantially smooth continuous material may comprise forming a continuous column-shaped material and cooling the column-shaped material by a cooled contact surface in contact with the continuous column-shaped material.
    [00046] The method may further comprise the step of splitting the joined continuous material, wherein the splitting step is performed by inserting a disc into the joined continuous material, wherein the disc is adapted to be rotatable along the transport direction of the substantially smooth material. Preferably, the splitting is carried out after the continuous material has been partially joined in one or more forming devices and before at least one forming device for joining or forming the continuous material into its final shape.
    [00047] In some preferred embodiments, the joining of the substantially smooth continuous material is carried out by means of a static forming element and the cooling is performed immediately after joining the continuous material. Thus, the cooling is obtained by a cooled contact surface in contact with the continuous bonded material disposed near an outlet of the static forming element. Preferably, the continuous material is joined in a column shape and the column-shaped material is then cooled.
    [00048] In some preferred embodiments, the joining is performed by means of at least two dynamic forming elements arranged subsequently to subsequently form a joined continuous material. Cooling of the substantially smooth continuous material is done at the same time as joining the substantially smooth continuous material or immediately after joining the substantially smooth continuous material. The method also comprises the step of arranging at least two dynamic forming elements at a distance from each other along the conveying direction of the substantially smooth continuous material, wherein at least two dynamic forming elements are arranged or comprise shape forming structures. that the continuous material is joined to a different extent by the two forming elements.
    [00049] As already highlighted above, the joint to a different extent may comprise joining the continuous material with at least two different dynamic forming elements in one or a combination of different widths, different general shapes or providing the continuous material with dimensions different from one formative structure.
    [00050] Other advantages and additional aspects of the method according to the invention have been described with reference to the apparatus according to the invention and therefore will not be repeated here.
    [00051] The apparatus and method according to the invention are particularly suitable for materials with a low glass transition temperature. In preferred applications, the continuous material formed in the apparatus according to the invention has a glass transition temperature below 150 degrees Celsius, for example below 100 degrees Celsius. Preferably, the continuous material is a plastic material, for example polylactic acid. The continuous material may be a crimped continuous material.
    [00052] The invention is further described with reference to embodiments, which are illustrated by means of the accompanying drawings, in which: Figure 1 shows a schematic overview of an embodiment of a filter manufacturing apparatus; Figure 2 illustrates a static forming device with a cooling device; Figure 3 shows a detail of the cooling device of Figure 2; Figure 4 shows an exploded view of a static forming device with integrated cooling; Figure 5 is a series of cross-sections through the forming device of Figure 4; Figure 6 shows a structured surface of the forming device of Figure 4; Figure 7 shows a dynamic forming device comprising pairs of forming rolls; Figure 8 shows a transport unit comprising pairs of splicing rollers; Figure 9, 10 is a side view and a cross-sectional view of a splitting unit; Figure 10-13 show a dynamic insert unit and insert unit details; Figure 14 shows a combination of forming devices.
    [00053] In the filter making apparatus shown schematically in Figure 1, a substantially smooth continuous material, such as a web of material 1, is supplied on a spool 10. When not wound by the spool 10, the web 1 is crimped, joined and cooled and wrapped in the apparatus. In this embodiment, the web 1, for example a polylactic acid (PLA) film, passes through a corona module 2 directly after being unwound from the reel 10. In the corona module 2, both sides of the web 1 are subsequently treated by corona in two portions 21,22 of the corona module. The corona treatment increases the wettability of the web 1 with an adhesive to improve the anchoring of the folded web in its wrapper. After corona treatment, the web 1 passes through a crimping device 4, for example a set of two crimping rollers. The crimping device 4 provides the weft with a crimped structure, for example with substantially parallel corrugations which preferably run in the longitudinal direction of the weft, i.e. in the transport direction of the weft 1. The crimping rolls can be cooled. . The weft 1 then passes through a forming device 5. The forming device 5 comprises forming rollers 50, preferably providing the crimped weft 1 with a longitudinally direction macro wave structure covering the crimped micro structure. Imposing the macro structure overlying the weft 1 causes the weft 1 to be pushed along a transverse direction of the weft 1. Furthermore, a retraction of the weft 1, for example in a column shape, is supported by the wave-like structure. longitudinal and can be performed in a more controlled manner. The forming device also comprises a converting device 51 arranged downstream of the forming rolls 50. In the converting device 51, the web 1 is further formed in column form, for example by grouping or pushing together. The forming device 5 or parts of the forming device are cooled. Preferably, upon exiting the conversion device 51, the frame 1 has not yet obtained its final shape, or is not collected entirely, respectively. This facilitates the introduction of an object, such as a capsule or flavored thread 71, into the continuous column of weft material. A flavor delivery system 7 comprising a continuous line 71 and a flavor reservoir 72 is arranged downstream of the former 5. The line 71 is mounted on a coil 70. Preferably, the flavor reservoir 72 contains menthol. The thread 71 is unwound from the spool 70 and infused with the aroma before being conveyed to the collected weft 1. The aroma application system 7 may be provided with at least one of a flow meter, a valve, a temperature control and a pump for controlling a defined amount of aroma to be applied to the thread 71. The aroma delivery system 7 is arranged above the weft 1 so that gravity assists the introduction of the thread into the weft. Gravity may also assist a flow of flavoring liquid along line 71. Alternatively, or in addition, flavor may be added separately from line 71 or may be omitted entirely. In that case, the presence of the line may have mostly an aesthetic contribution to the aerosol generating article.
    [00054] A continuous wrapping material 6, e.g. paper, is supplied on a spool 60 and supplied below the continuous column so that the continuous column of weft material meets the wrapping material 6. The wrapping material 6 passes parallel to the continuous column when being joined with the column. Before the shell material 6 and the continuous column are joined, the shell material is supplied with the glue. A glue reservoir 62 is in fluid connection with a splicing nozzle 64 as well as an anchor nozzle 63. Glue from the glue reservoir 62 is transported through an adhesive pipeline, e.g. a tube, to the anchor nozzle. and the splicing nozzle. With the anchor mouth 63, the anchor collar is applied to the wrapping material so that the wrapping can be securely glued to the weft material. With the splice nozzle 64, splicing glue is applied to the wrapper material 6 to glue the wrapper material to itself after the wrapper material has been fully wrapped around the continuous column of weft material. In this embodiment, the glue reservoir 62 contains a glue, which can be used to anchor and splice the shell material.
    [00055] However, if a different glue is used, a reservoir for each, for anchoring and for splicing, can be provided. A different glue may be advantageous, for example, if a wrapper material is a paper wrapper and paper glue is used for the seam and if, for example, specific plastics glue is used to anchor the wrapper to a material. of the plastic mesh of the continuous column. Also, glue can vary with respect to the bonding moment of the glue. For example, a polyurethane glue and a hot melt adhesive can be used for different purposes.
    [00056] The wrapped continuous column of weft material can be guided in a column-shaped bed 52 which passes through a heating device 53 to heat the wrapped continuous column. Heating facilitates quick distribution and drying of the glue. After the continuous column has been formed, it is cut within the cutting device 8 into segments of the predefined length, for example with single or double length segments (having the length or twice the length of a final product). The cutting device or a strong cutting device knife can be cooled. The column segments may be transported to a tray or storage 91. The column segment may also be directly transported to a combiner 92 to be combined with additional elements, e.g., an additional filter elements or segments, e.g. , aerosol generating articles.
    [00057] An in-line control unit 90 is provided after the continuous column is cut into segments for quality control of the manufactured segments. In the position of the tray 91, an off-line control unit 93 can be provided. An in-line control unit 90 and the off-line control unit 93 can, for example, include a length control, diameter control, weight, ovality control, drag resistance (RTD) control, line centering and other visual quality aspects of the semi-finished or finished product. The off-line control unit 93 can, for example, also be provided with a measuring device for an index of menthol or other substances in the column segment. In tray 91, the segments can be labeled, for example, with a group number, a production date or a product code, for example, to track the products.
    [00058] Preferably, tension rollers 30 and drive rollers 31 are provided in the apparatus for controlled transport of the web of material 1 and continuous, preferably constant, tensioning of the web. The synchronization means may be provided between the crimping device 4 and a conveyor means, such as a continuous belt, for example, at the position of the in-line control unit 90. By the synchronization means, a linear speed of the continuous column and the substantially smooth continuous material not yet grouped in the crimping device 4 can be synchronized.
    [00059] Figure 2 is an embodiment of a static forming device 500 comprising a cooling device in the form of an intermediate heat exchanger tongue 75. A trim tongue 510 as known in the art for forming column-shaped web 1 has a cutting end portion 511. The intermediate heat exchanger tongue 75 is disposed directly adjacent to and aligned with the cutting end portion 511 of the trim tongue 510. The intermediate heat exchanger tongue 75 is provided with a sealing surface. cooling 752 in direct contact with the guided web within the forming device.
    [00060] The intermediate heat exchanger tongue 75 comprises a coolant inlet 750 and a coolant outlet 751 for guiding the cooling fluid, e.g. air or liquid, in the tongue of the intermediate heat exchanger 75. Preferably, an intermediate heat exchanger tongue 75 is made of a thermally conductive material so that at least the cooling surface 752 is cooled by conducting heat from the coolant to the cooling surface.
    [00061] The cooling surface 752 has a concave shape to keep the weft 1 in contact with the cooling surface 752 in the form of a column. As shown in more detail in Figure 3, the shape of the cooling surface 752 varies along the length of the cooling device 75. The cooling surface 752 is provided with a narrowing radius of curvature as opposed to a downstream end 7520 of the cooling device 752. surface such as to then form the web 1 in the form of a column. The cooling surface 752 has a continuously decreasing height 7521 along the length of the cooling device 75. Thus, the cooling surface 752 is arranged obliquely with respect to a horizontal support 110 relative to the transport direction of the web. The weft 1 is continuously guided on the trim tongue 510 and on the cooling device 75. A support 110 of the weft 1 is guided along and comprises a longitudinal groove 1100 in the form of a half circle for receiving the weft in the form of a column. .
    [00062] The cooling surface 752 may also have a constant shape and orientation along the length of the tongue of the intermediate heat exchanger 75.
    [00063] Figure 4 shows another static former device 501 with integrated cooling system. The cooling device 501 comprises an upper and lower forming plate 515,516. The forming plates comprise a plurality of longitudinally arranged structures 519,520 in the form of ridges and valleys. The ridges and valleys converge opposite a downstream end of the plates. Frames 519 on upper former plate 515 correspond to frames 520 on lower former plate. A continuous web of material 1 carried between the two forming plates 515,516, for example a PLA sheet, is continuously provided with a macrostructure corresponding to the structures of the plates. A cover plate 517 and a base plate 518 to which the forming device 501 can be mounted are preferably cooled by a chilled liquid (not shown). Preferably, all the plates are made of a heat-conducting material so that the web 1 can be cooled by heat transfer through the plates 515,516,517,518. Preferably, the temperature of a PLA web is kept below 50 degrees Celsius, preferably below 40 degrees, more preferably below 30 degrees.
    [00064] Air slots 755 are provided on the back side of the forming plates 515,516. In addition, several lines of through holes 756 are provided on the forming plates as can be seen in Figure 6. These lines of through holes 756 are arranged at a distance from each other and transverse to the longitudinal structures 519,520 on the plates. formers 515,516. The air holes are in fluid communication with the air slots 755. Compressed air may be introduced into the slots 755 and may pass through the hole 756 to support a PLA blade inlet between the former plates 515,516. Furthermore, the friction between the forming plates and the web can be reduced and the web can be further cooled by air.
    [00065] In Figure 5, various cross-sections 525-529 through the closed forming plates 515,516 are shown. From top to bottom, the cross sections refer to the different longitudinal positions of the forming plates 515, 516 when viewed in the transport direction of the web 1 (indicated by the arrow). The structures 519,520 on the forming plates 515,516 are expressed more in the center 521 of the plates than on the lateral sides 522 of the plates. A height of the structure (ridges) grows continuously also towards a downstream orientation. In this example, distances 530 between individual crests or valleys remain constant.
    [00066] The individual cross-sections 525-529 can also correspond to the cross-sections of a series of individual static forming elements arranged at a distance from each other along the transport direction of the web 1. Several individual static forming elements allow, for example, a ambient air cooling between the individual forming elements.
    [00067] Figure 7 shows a dynamic forming device 502, wherein a plurality of pairs of forming rolls are arranged in parallel with each other. The individual roller pairs are spaced apart along the web transport direction. The upper and lower forming rolls 531, 532 comprise circumferentially shaped passage structures 535, 536 which correspond to each other. The structures 535, 536 defined by discs arranged in parallel along a length of a roll are expressed more at the center of the roll than at the lateral edges of the roll. The center of a weft (middle line) guided between the forming roll pairs is formed more at the center than at the side edges of the weft. A frame height 535, 536 is increasing with the progressive shape of the weft. In this example, a distance 540 between individual structures (disks) is decreasing from a center to the side edges of the forming rolls 531,532.
    [00068] The rollers 531, 532 rotate along the transport direction of the weft that moves between the rollers, thus reducing the friction between the rollers and the weft. A cooling of the forming rolls 531,532 may be provided.
    [00069] The dynamic forming device 503 of Figure 8 comprises three pairs of splicing rollers. The pairs are arranged at a distance from each other along the transport direction of the weft 1. Each of the pairs comprises two splicing rollers 541,542; 543,544; 545,546 arranged opposite each other and so as to rotate along the web transport direction. The splicing rolls each have a groove 5420,5410;5440;5460,5450 arranged on their circumference. The splicing rolls have a rotating axis perpendicular to the transport direction of the web 1 so that the web is guided and joined in and through the grooves of the splicing rolls 541,542; 543,544, 545,546 when passing through forming device 503. Preferably, slots 5420,5410; 5440;5460,5450 of each pair of rollers have a similar shape. Preferably, the grooves of different pairs of splicing rollers have a different radius of curvature. The further downstream the pair of rollers is, the less the radius of curvature of the grooves will be. In an alternative embodiment, the grooves of pairs of different splicing rolls are of equal shape, but the two splicing rolls of a pair are arranged at different distances from each other. In this alternative embodiment, the distance between the splicing rolls of a pair of rolls arranged further upstream is greater than the distance between a portion of splicing rolls arranged further downstream.
    [00070] The grooves 5410,5420 of the first most upstream pair of the splicing rollers 541,542 have an oval shape, the grooves 5440 of the second pair and middle pair of the splicing rollers 543,544 have a half oval shape and the grooves 5450,5460 of the third most downstream pair of splicing rolls 545,546 have a semicircular shape. Hereby, the web of material 1 is joined in stages to an oval shape 12a to a column shape 14.
    [00071] An auxiliary roller 548 is arranged upstream of each of the pairs of splicing rollers. Auxiliary rollers 548 are arranged above weft 1 and extend over the width of weft 1. Auxiliary rollers 548 support a positioning of the weft for insertion into dynamic forming device 503, in particular within the grooves of splice rollers 541,542; 543,544; 545,546.
    [00072] A splicing roll 542,544,546 of each splicing roller part can be movable in a lateral direction. This facilitates the insertion of the weft 1 into the forming device 503 and maintenance of the device. Likewise, a distance between rollers of a pair can then be varied.
    [00073] Some or all of the splicing rolls can be cooled.
    [00074] A splitting unit 65 is arranged between the second and third pair of splicing rollers. With the dividing unit 65, the entire column-formed weft material 13 is divided for insertion of a scent object, for example, a thread or a capsule (not shown). In Figure 9 and Figure 10, the division unit is shown in more detail. Two splitting rollers 650, 651 are rotating in the weft transport direction 1. The splitting rollers 650,651 have a rotating axis arranged parallel to the weft, parallel to each other and perpendicular to the weft transport direction 1. The rollers Splitting rollers 650,651 have a concave shape as seen in the cross-sectional view of Figure 11. The upper splitting roller 650 has a circumferentially shaped passing disc 652 disposed at the center of the forming roller 650. The partially joined web 13 is guided on the e.g. through the space 653 spanned between and by two split rollers 650,651. In this way, the disc 652 of the upper roll 650 is inserted into the web and opens a channel in the weft. The space 653 between the split rollers 650, 651 can be varied and fixed in a position defined by the adjustment knob 655.
    [00075] Figure 11 shows an embodiment of a dynamic forming device 506. Preferably, the forming device 506 is arranged downstream of other forming rolls, so that the web 1 entering the dynamic forming device 506 of Figure 11 already has a column shape or near-column shape.
    [00076] The forming device 506 comprises two preforming rolls 560,561. The preform rolls 560,561 are arranged and rotate in line with the web carried through the dynamic forming device 506. As can be seen in Figure 12, the upstream preform roll 650 is symmetrical with respect to its coming into shape. contact with the plot. The web 1 passing the symmetrical preformer roll 650 is guided in the concave shape of the circumference of the symmetrical preformer roll. As shown in Figure 13, the most downstream disposed preform roll 651 is asymmetrical with respect to its shape in contact with the web. Only about a quarter of the circumference of the substantially column-shaped weft 14 is guided by the asymmetric preform roll 561, thus reducing contact between the roll and the weft.
    [00077] A support 567 is provided with a longitudinal groove 567 having a concave shape, in which the substantially column-shaped web is carried. The support 567 also comprises a cover 566, partially covering the support and the weft disposed in the groove 567. Preferably, the cover does not contact the weft, but serves as a retaining element holding the weft in the groove 567.
    [00078] An adjustment knob 565 is provided for adjusting and setting the preformer rolls 560,561 to a defined diameter value of the web passing through the dynamic forming device 506. In addition, the dynamic forming device 506 can be removed by loosening the adjustment knob 565. By this, the material jam in the device can be removed quickly and conveniently.
    [00079] The dynamic forming device 506 may comprise other preforming rolls arranged downstream of each other in the web transport direction. The other preform rolls can be symmetrical or asymmetrical. One, several or all preform rolls 560, 561 can be cooled.
    [00080] Preferably, the static forming device 500 as shown in Figure 2 is used as an alternative to the dynamic forming device 506 of Figure 11.
    [00081] In Figure 14 an exemplary combination of different forming devices is shown. A web with past schematically indicated crimping rolls 4 subsequently passes to the forming device 500 and the two dynamic forming devices 501 and 506. After leaving the further downstream forming device 506, the web is fed to the column forming zone 52 which can be designed as known in the art and which is not further described. The web 1 is subsequently formed into a column shape by the forming devices. The individual forming device can be replaced by different forming devices. For example, static forming device 500 can be replaced by the dynamic forming device of Figure 7. Both forming devices provide the weft with a macrostructure. The two dynamic forming devices 500, 501 can, for example, be replaced by a static forming device comprising a gasket tongue as shown in Figure 2.
