    The invention relates to a device for discharging at least one sheet of a web and sheet processing machine or component.
    Furthermore, the invention is directed to a method for discharging sheets or webs of a sheet or web-processing machine or component.
    Extraction devices are known from the prior art, for example in the form of a Makulaturausschleusung or a Makulaturweiche. Thus, DE 2052924 discloses a device for discharging control or waste sheet from a folder.
    Also in the EP 020 966 A1 a solution for the removal of sample or copy copies is described in which by means of a Makulaturweiche the corresponding sheet are removed from the folder.
    Furthermore, from the prior art, various solutions so-called waste macros are known, with which, for example, isolated folded or unfolded sheets or even a single sheet preferably copy accurate from a tape or a cylinder and removed from the corresponding component can be removed. In this case, it is not relevant according to the prior art whether the sheet or sheets to be rejected are unfolded or already folded. Furthermore, sheets can also consist of several, so to speak superimposed to form a sheet pile single sheets.
    Because of this variety of types of sheets, the term "sheet" will be used hereinafter for unfolded, already folded single sheets as well as for unfolded and already folded sheet stacks.
    Furthermore, waste macros are known from the prior art, to which, for example, in the case of a stopper in a sheet-processing component such as a folder which are ejected to stop the machine subsequent sheets to avoid stoppers in the folder.
    Allen known from the prior art Ausschleusvorrichtungen or Makulaturweichen is common that although the transport direction of the discharged sheets can be changed, but not in the form that the sheets with little space at right angles to the first, original transport direction and in the right angle to the longitudinal axis of the sheet processing component can be led out of the component.
    This leads according to the prior art either to long conveyor paths to promote the discharged sheets out of the machine. In particular, with a high output of sheets, this can lead to problems with conveying away in long conveyor belts, moreover, the conveying of disorderly and loose, possibly even piled lying on a conveyor belt arches at Eckumlenkungen, which are usually required for transport away from the component , highly critical and often leads to stoppers and blockages.
    Thus, according to the state of the art discharged sheets either in the sheet-processing component or in there positioned containers are conveyed or thrown into it, but this can also lead to problems. Furthermore, the size of the container is usually limited due to the spatial conditions, so that it must be emptied after a short time in case of waste. Especially with large, unfolded sheets such containers are usually filled after a few seconds, a maximum of a few minutes and must be replaced.
    The invention is therefore an object of the invention to provide a solution with which it is possible to deflect the discharged bows by means of a discharge device in a very small space in the form that they can be transported away from the sheet processing component.
    In the inventive device or in the inventive method, this object is achieved in that the discharge device consists of a folding funnel-like Längsfalzvorrichtung.
    Such a longitudinal folding device has, on the one hand, the advantage that the single or the plurality of sheets can be deflected in the narrowest space and, for example, can be discharged out of the machine perpendicular to the machine axis or to the longitudinal axis of the component and thus on the shortest path. Furthermore, in contrast to so-called corner deflections the discharged sheets are permanently guided and not piled on each other, so that it can not lead to congestion, stoppers or slippage of the sheets with all the resulting disadvantages.
    Another significant advantage of the invention is that the discharged sheets can be folded during discharge by the longitudinal folding device, whereby the sheets can be filled in smaller containers and / or a higher filling density, i. gives a higher number of sheets per unit volume.
    Thus, a first embodiment of the invention is that in a sheet-processing machine or a sheet-processing component such as a folding unit or a sheet stacker from a well-known in the art Makulaturweiche in which auszuschleusende sheets such as unprinted sheets, so-called White waste or sheets of inadequate quality, such as waste sheets, are removed from the main product stream and transported on in a strip line.
    Instead of laying the discharged sheets on a conveyor belt or to drop directly from the tape line, for example, in a container, the guided in the ribbon line sheets are fed in a first direction to the Längsfalzvorrichtung, wherein the at least one sheet preferably between at least one Upper band and a lower band is performed. This inlet-side conveyor belt can either end at the base edge of the longitudinal folding device or by at least one upper and / or lower belt of auszuschleusende sheet is still performed on the Längsfalzeinrichtung.
    The auszuschleusende sheet is centered or eccentrically guided over the Längsfalzvorrichtung, so that when viewed in the first direction of transport outside lying edges, if the sheet is passed over the so-called funnel tip. By this impact of the outer edges of the sheet is folded in the longitudinal direction on the center line of the longitudinal folding device.
    In the event that the sheet in the form runs eccentrically over the Längsfalzvorrichtung than that does not protrude beyond the center line of the longitudinal folding device, the sheet runs on one leg of the Längsfalzvorrichtung and is at this from its first transport direction into a second Direction of transport deflected without the sheet is folded in the longitudinal direction.
    In the possibilities, however, is common that the second transport direction is in at least one plane approximately perpendicular to the first transport direction.
    The spatial angular position of the first and the second transport direction is fundamentally variable according to the funnel laws by means of the geometry of the longitudinal folding device, but preferably the first and the second transport direction are perpendicular to each other in at least one plane.
    In an advantageous embodiment of the invention comes as Längsfalzeinrichtung a so-called inner funnel used. This consists of a triangular or substantially triangular sliding plate, wherein on the legs of the sliding plate in the same direction pointing guide elements are attached, which enclose an angle of preferably 90 ° to 30 ° with the sliding plate. The thus resulting edges between the sliding plate and the guide elements on the legs of the sliding plate have a rounded transition, which is designed for example as a radius. On the inlet side of the sliding plate, a first transport device is mounted, for example in the form of a ribbon cable, which conveys the substrate to be folded on the base edge of the sliding plate opposite the two legs. At the opposite corner of the base edge, the two guide elements do not collide, but end before, so that between these seen in the transport direction of the substrate to be folded outlet edges an exit opening for the substrate to be folded remains.
    Such an inner hopper has the particular advantage that advantageously the inlet-side transport device protrudes into the sliding plate, however, a relatively expensive band guide around the legs of the triangular Längsfalzvorrichtung can be omitted as a rule, whereby such Längsfalzvorrichtung technically simple, thus cost and procedural can be operated very reliably with single sheets.
    In a further advantageous embodiment of the invention comes as a discharging device, a so-called Aussentrichter used, as this is known from the prior art, for example from DE 591 965. In this type of longitudinal folding device, the sheet runs on the outside over the hopper plate and surrounds the outside of the funnel legs.
    In this case, it may be necessary or helpful in particular during folding or deflection of bends to also attach a ribbon cable to the funnel legs in order to ensure looping around the funnel legs through a bend.
    Since the geometry of a so-called outer funnel is in principle identical to that of the inner funnel, thus also the folded or unfolded sheet is deflected in the same manner from the first transport direction in a second transport direction.
    In a particularly advantageous embodiment of the invention, the falztrichterartige Längsfalzvorrichtung on the outlet side at least one conveyor belt for guiding the auszuschleusenden sheet. This conveyor belt is preferably formed as a stripline consisting of at least one upper belt and at least one lower belt in order to ensure a secure guidance of the moving in the second transport direction bow.
    Thus, a particularly advantageous embodiment of the invention, namely seen in a projection of the sheet-processing machine or component to the machine axis or first transport direction seen vertical removal of the discharged sheet can be ensured.
    Preferred embodiments of the invention will become apparent from the dependent claims and the description below. Various embodiments of the invention will be described, without being limited thereto, with reference to the drawings.

    Fig. 1 shows the example of a folding unit, a component 4 of a machine 3, in which at least from a certain section sheet 2 are processed from a flexible and / or falzbaren substrate. Thus, in the example of component 4 shown in FIG. 1, a preferably printed substrate web is processed into individual sheets 2 by means of a cross-cutting device. The web can be folded or at least partially folded before cutting and thus before separating into sheets 2, for example with a longitudinal folding device. Further, it is possible that the web was already divided in the web running direction in strands before the cross cutting in sheets 2, which were then superimposed. Thus, a sheet 2 can also be a plurality of individual sheets lying one above the other. As mentioned above, in this invention, the term sheet 2 is used both for individual sheets and a stack of sheets stacked sheets, it is also irrelevant for the term sheet 2, whether the sheet has one or more folds in or transverse to the transport direction or whether the substrate of the sheet 2 is printed or unprinted.
    In the example shown in Fig. 1, the discharge device 1 according to the invention is downstream of a waste gate 20, but the discharge device 1 can also be operated without a previous waste gate, i. be integrated into a component for discharging each sheet 2.
    The Makulaturweiche 20 selectively expels one or a plurality of sheets 2, for example, because they are not printed or insufficient, have deviations in the position of the cut to print, etc. In digital printing machines, for example, such waste may be incurred until the startup process, the machine the printing speed is reached or the machine 3 changes over to the new format due to the possible format variability, which can lead to very few copies of the paper in the case of very large format jumps.
    The Makulaturweiche selectively removes sheet 2 from a preferably designed as a ribbon conveyor 9 and leads the sheet 2 in a first direction of movement 5 to the discharge device 1 to.
    The conveyor 9 is hereby preferably, but not necessarily designed as a ribbon cable 15, wherein the sheet 2 is transverse to the first direction 5 seen between at least one top band 15-1 and a lower band 15-2 out.
    The sheet 2 is now performed for discharging from the component 4 on a Längsfalzvorrichtung 6, which seen perpendicular to the first direction of movement 5 substantially has a triangular shape.
    The longitudinal folding device 6 can be designed either as an outer funnel 8 or as a so-called inner funnel 7.
    Outer funnels are known from the prior art and are often used there for folding web-like substrates in the transport direction. Thus, an outdoor funnel usually consists of a triangular or triangular funnel plate, which is usually formed as an isosceles triangle. At the corner opposite the base edge, an outer funnel has a so-called funnel nose over which the substrate already wrapped passes and the longitudinal fold, i. the fold is formed in the transport direction of the substrate. The funnel legs can consist of a tubular material, or the sliding plate is bent away from the sliding surface in a radius-like manner.
    However, the longitudinal folding device 6 can preferably also be designed as a so-called inner funnel 7, which is described in different embodiments with reference to FIGS. 5 to 8.
    A designed as an inner funnel 7 Längsfalzeinrichtung 6 has the advantage that thus isolated sheet 2 can be folded highly reliably at high speeds. If sheets 2 are guided over an outer funnel 8, then it is generally necessary for this that at least one conveyor belt 9 is guided over the outer funnel 8. Although this is to guide the sheets 2 in an inner funnel 7 advantage, but should advantageously at an outer funnel 8 each at least one conveyor belt 9 are guided transversely to the first direction of movement 5 on the funnel legs to ensure a hammering of the sheet.
    About the serving as a discharge device 1 Längsfalzeinrichtung 6 of auszuschleusende sheet 2 can be performed either centrally or eccentrically so that the arc symmetrical or asymmetrical over the center plane 11 of the longitudinal folding device 6 runs. This center plane 11 is parallel to the first direction of movement 5 and divides the Längsfalzeinrichtung 6 symmetrically. In such a guide of the sheet 2 on the longitudinal folding device 6, the sheet 2 is folded in or parallel to the first direction of movement 5 and deflected to or with the Längsfalzvorgang in the second direction of movement 10.
    However, it is also possible to convey the at least one sheet 2 so eccentrically on the Längsfalzvorrichtung 6, that the sheet 2 is only on one side of the running in alignment with the first direction of movement 5 center plane 11 of the Falztrichterartigen Längsfalzvorrichtung 6, so that the sheet 2 is guided without design of a longitudinal fold on the discharge device and is deflected in the second direction of movement 10.
    As can be seen from Fig. 1, both in guiding the sheet 2 over the center plane 11 away or in such eccentric leadership on the Längsfalzvorrichtung 6, wherein the sheet 2, the center plane 11 does not exceed, the bow depends on the Geometry, ie the size, the shape, the spatial arrangement of the longitudinal folding device 6 in the component 4 and the first direction of movement 5 deflected in a second transport direction 10, whereby the Auszuschleusende sheet 2 can be led out by the shortest route and with extremely little space from the component 4. This outward conveying can preferably take place approximately at a right angle to the longitudinal axis of the machine 3 or the component 4.
    If the sheet 2 after the Längsfalzvorrichtung 6 even further deflected by means of a transport device 12 and / or a pair of rollers 13, it may, as shown in Fig. 1, on a horizontal plane approximately perpendicular to the first direction of movement 5 and perpendicular be promoted out to the longitudinal axis of the machine 3 and the component 5 out, which brings a significant space savings.
    2, the discharge device 1 is shown in more detail, so that more details of the longitudinal folding device 6 optional downstream transport device 12 emerge from Fig. 2.
    Thus, the discharged and optionally folded sheet 2 is advantageously taken after exiting the Längsfalzvorrichtung 6 by a transport device 12. This transport device 12 may be formed either as a simple conveyor belt 14, on which the auszuschleusende sheet is stored and transported out of the component 4 from the machine 3 out.
    Advantageously, however, the transport device 12 is formed as a ribbon cable 15 consisting of over the width of auszuschleusenden sheet 2 each having at least one upper band 15-1 and a lower band 15-2. With a designed as a ribbon cable 15 transport device 12 is on the one hand the best possible and thus performed without the risk of slipping the sheet 2, on the other hand so that a certain tensile force can be built so that the sheet 2 during transport over the longitudinal folding device 6 away better or permanent is guided, in particular if the inlet-side conveyor 9, the hopper plate in the case of an outer hopper 8 or the sliding plate in the case of an inner funnel 7 at least one side and at least partially covered.
    Both for deflecting the ribbon cable 15 and for additional stamping of the Längsfalzvorrichtung 6 optionally formed Längsfalzes and in particular for deflecting the sheet 2, for example, as shown in Fig. 2 in a horizontal plane of the Längsfalzvorrichtung 6 is additionally followed by a pair of rollers 13. In Fig. 2 shows an embodiment in which the pair of rollers 13 is made of different sized rollers, which are not hired to each other. However, the size or the diameter of the rollers is not relevant to the invention, the rollers of the roller pair 13 may also have the same size or the same diameter.
    However, it is also possible to perform the pair of rollers 13 such that the rollers are employed to each other in order to better express the longitudinal fold or to be able to transmit a stronger tension on the sheet, in particular if at least one roller of the roller pair thirteenth is driven. In such an embodiment of the roller pair 13, the ribbon cable 15 can be deflected either via separate, additional rollers or it can have the rollers of the roller pair 13 groove-like recesses on its lateral surface, in which the bands of the ribbon cable 15 are performed.
    Fig. 3 shows a three-dimensional view of the inventive discharge device, from which in particular a particularly advantageous embodiment of the inlet-side conveyor 9 and outlet-side transport device 12 is apparent. For in a particularly advantageous embodiment of the inventive discharge device 1, the inlet-side conveyor 9 covers the Längsfalzvorrichtung 6 at least partially, so that the Auszuschleusende sheet 2 is performed as long as possible to the folding or deflection. After the exit of the leading edge of the sheet 2 from the Längsfalzvorrichtung this is directly from the outlet side transport device 12, which is advantageously designed as a ribbon line 15 of upper band 15-1 and lower band 15-2, detected, so that the sheet 2 during the deflection or folding only a short section is not performed by a conveyor. Such an intensive guidance enables reliable operation even with sheets 2 of high mass and / or at high conveying speeds of the sheets 2.
    Fig. 4 shows a three-dimensional view of a formed as an inner funnel 7 Längsfalzvorrichtung illustrating the sheet guide in this embodiment of the invention, although without inlet and outlet side transport device.
    5 shows a first embodiment of the inventive longitudinal folding device 101 in the form of a so-called inner funnel. This comprises a former 103 of a nearly triangular or triangular sliding plate 110, which has a base edge 111 on the inlet side 104, to which the two funnel legs 112 adjoin. With regard to the triangular shape, it should be noted that the sliding plate 110 can not be an exact triangle, since in various embodiments, the corner opposite the base edge 111 can be omitted due to a shortening of the sliding plate 110, nevertheless a triangle describes the basic design of the sliding plate 110 most clearly.
    Preferably, the sliding plate 110 is designed as an isosceles triangle to ensure a symmetrical folding. However, the sliding plate can also be designed, for example, with rounded or curved funnel limbs 112 or even a rounded or, for example, rounded base edge 111, or the funnel limbs 112 can also be designed, for example, as angled lines. With such embodiments, in which in particular the funnel legs 112 are not designed as a straight edge, the folding and / or discontinuation behavior can be changed. Because of these possible shapes of sliding plate 110, which deviate from a classical triangle, these possible designs are covered by the concept of a triangular shape.
    If one assumes that the longitudinally folded web 102 or the longitudinally folded sheets 102 are to exit the longitudinal folding device 101 according to the invention lying on a vertical plane from the longitudinal folding device 101, then the required angles result due to the funnel laws, wherein it is hereby noted that that these are all correlated to each other, so that usually has to change when changing an angle and another angle. As a rule, the base edge 111 serving as the leading edge lies on a horizontal plane, thus resulting in an angle of incidence β of the sliding plate 110, which is the angle between a vertical plane and the triangular surface of the sliding plate 110, of approximately 10 ° to approximately 40 ° °.
    For an embodiment in which the sliding plate 110 has the shape of an isosceles triangle, so this has a known from the field of the outer funnel funnel angle a, which is the base edge 111 opposite, from about 40 ° to about 90 °. The dimensions of the sliding plate 11, in particular the required effective width of the base edge 111, results from the size and, in particular, from the maximum width of the substrates to be folded, such as web 102 or sheet 102.
    With regard to the substrates to be folded is noted at this point that the inventive inner funnel 101 and the inventive formers 107 can fold both in the width limited but in length actually endless tracks 102, which is a single track 102 or a Can act plurality of superposed tracks 102 of the same or different width. Also, with the inventive longitudinal folding device 101 or the inventive designed as inner funnel folding hopper 107 both in width and in length limited arc 102 or more superimposed sheets 102, so-called sheet stack 102 are folded, regardless of whether this at least one track 102nd or a single sheet 102 or the sheet stack 102 is still unfolded or already has a fold in or transverse to the transport direction of the sheet 102 or sheet 102 to be folded. For this reason, the term of the substrate 102 or of the substrate 102 to be folded is often used hereinafter as well. In the case of sheet stacks 102, it is an advantage, but not a mandatory feature, that the sheets 102 of the sheet stack 102 have a certain cohesion with one another, for example by electrostatic blocking, auxiliary glueing or, for example, gluing.
    At each funnel leg 112 of the sliding plate 110 of the inner funnel 107 one or more juxtaposed guide elements 114 are attached in each case. Each of the two guide elements 114 begin at the base edge 111, seen in the direction of transport 103 in width perpendicular to the sliding plate 110 and form the outlet end, which is usually on a horizontal plane, assuming that the folded products 102 of the former are to be output 107 in a vertical plane.
    Between the sliding plate 110 and the two guide elements 114 exists a bending angle y, which is in a range of about 100 ° to 20 °, preferably in a range of 90 ° to 30 °. Usually, the bending angle over the entire length of the funnel legs 112 is constant, but it is also possible that the bending angle v changes over the length of the funnel legs 112.
    Depending on the geometry of the longitudinal folding device 101 and / or the substrate 102 to be folded, it may be advantageous that the bending angle represents an obtuse angle, but usually the bending angle is either a right angle or an acute angle.
    In order to ensure a good transition, in particular of the edges of the substrate to be folded, the edge between a guide element 114 and the sliding plate 110 is rounded, such as by a radius or a radius-like transition executed. The radius r is advantageously in a range between about 20 to 80 mm. This radius r can be made constant or variable over the length of the funnel leg 112. In the case of a variable radius over the length of the funnel leg 112, it is usually larger in the region of the base edge 111 than on the outlet side of the longitudinal folding device 107 designed according to the invention as an inner funnel.
    As materials for the sliding plate 110 and the guide elements 114 can be used in addition to metallic materials such as preferably steel non-metallic materials such as ceramics, plastics or fiber composites to minimize possible wear, these components can in particular on the with the to be folded Substrate in contact surfaces with low-wear materials such as ceramic coatings, hard chrome, etc. are coated. However, it is also possible to subject the surfaces coming into contact with the substrate 102 to be folded, if appropriate, in addition to a wear-inhibiting coating with an air cushion in order to minimize possible wear by the air cushion.
    At the outlet end of the sliding plate 110, the ends of the guide elements 114 do not collide, but form an outlet opening 115, through which the folded substrate 102 can emerge from the longitudinal folding device 101 according to the invention. This outlet opening 115 usually has a width of about 20 mm to 100 mm, which on the one hand depends on the geometry of the longitudinal folding device 101 and on the substrate to be folded.
    At the inlet side 104, the longitudinal folding device 101 according to the invention has a feed-side transport device designed as a ribbon line 120 for the substrate to be folded. In principle, this inlet-side transport device can also consist of one or more draw rollers or transport rollers. The use of a ribbon cable 120, however, has the advantages that it can be promoted very easily and precisely even to be folded sheets 102 or sheet stack 102. In the simplest case, this inlet-side strip line 120 can be designed as only one strip, which is in contact with only one side of the incoming substrate 102; if necessary, a draw roll can start on the side opposite the strip.
    Preferably, the inlet-side strip line consists of an upper belt 120-1 and a lower belt 120-2, between which the substrate 102 to be folded is clamped and transported to or into the longitudinal folding device 101. Usually, but not exclusively, over the width of the incoming substrate 102 and thus across the width of the base edge 111 of the sliding plate 110, a plurality of adjacent upper bands 120-1 and lower bands 120-2 are used. But it is also possible that the ribbon 120 consists only of a band over the width of the base edge 111.
    On the outlet side 105 of the longitudinal folding device 101 is usually also a conveyor 125 is attached. However, this can also be omitted if, for example, an endless web 102 is folded, which is conveyed again by one of the longitudinal folding device 101 downstream component, so that builds up a corresponding web tension between the outlet side 105 and the inlet side 104 of the longitudinal folding device 101.
    Preferably, this outfeed-side conveyor device 125 is constructed as an outfeed ribbon cable 127 which again clamps the longitudinally folded substrate 102 between a top band 127-1 and a bottom band 127-2 so that a corresponding draft is established. Such an embodiment is shown in Fig. 5. Usually, there are a plurality of adjacent bands across the width of the folded substrate 102; but there is also a possibility that over the width of the folded substrate 102, only a possibly wider band is arranged.
    Another advantageous embodiment of the invention is a conveying device, which is formed from at least one pair of rollers 126, in which two rollers are employed to each other and at least one roller is driven, so that by adjusting the two rollers to each other a web tension can be established ,
    In a particularly advantageous embodiment of the invention, the conveyor 125 consists of a combination of a pair of rollers 126, which acts as Zugwalzenpaar, and a run-out thereon ribbon cable 127, so that the folded substrate 102 of the pair of rollers 126 optimally pulled and from the outlet ribbon cable 127, which preferably consists of a top band 127-1 and a bottom band 127-2, stably guided and transported.
    Advantageously, but not necessarily, the inventive Längsfalzeinrichtung 101 is dimensioned and designed so that the length of the sliding plate 110 seen in the transport direction 103 is shorter than the length of the sheet to be folded 102. However, since, for example, in format variable printing, cutting or folding systems the length of the sheets to be folded 102 is strongly variable, even very short sheets 102 must be optimally managed.
    For this purpose, an advantageous embodiment of the invention is shown in Fig. 6, wherein at least one inlet-side ribbon line 120 on the guide elements 114 facing side of the sliding plate 110 and thus on the web or sheet-guiding side of the sliding plate 110 in the transport direction 103 seen above serving as the leading edge base edge 111 goes out, so that the substrate to be folded 102 at least in a portion over the width of the sliding plate 110 and thus at least a portion over the width of the substrate to be folded 102 substantially longer between the guide elements 114 facing band of the ribbon line 120 is guided. Thus, also sheets 102 can be folded, which seen in the transport direction 103 have a smaller length than the length of the sliding plate 110.
    Here, the substrate 102 either, as shown in Fig. 6, between the sliding plate 110 and a band, which is then commonly referred to as upper band 120-1, is guided, wherein in such a configuration, the over the base edge 111 of Sliding plate 110 extending band line 120 is designed as an over the sliding plate 110 sliding upper band 120-1.
    In a particularly advantageous embodiment of the invention consists, as shown in Fig. 7, the entire inlet-side ribbon cable 120 protrudes from at least one top band 120-1 and at least one sub-band 120-2 consisting, in at least one section over the width of the sliding plate 110, seen in the transport direction 103 beyond the base edge 111 of the sliding plate 110 addition. In order to be able to guide the substrate 102 to be folded 102 between the upper belt 120-1 and the lower belt 120-2 in such a configuration of the ribbon cable 120, the sliding sheet 110 has to be at the sections at which the width of the base edge 111 bandlines 120 consisting of upper band 120-1 and lower band 120-2 are mounted, seen in the transport direction 103 at least partially cutouts 113 have. At these recesses 113 tape rolls are either for the upper belt 120-1 and / or for the lower belt 120-2 attached to ensure at these points a clamping point between the upper belt 120-1 and lower belt 120-2, clamped by which the substrate 102 to be folded and thus guided or transported.
    However, it is also possible in the embodiment shown in FIG. 7, in which at least one region, to which a stripline 120 extending beyond the base edge 111 is attached, to completely blank out the sliding plate 110 over the length of the ribbon line 120, so that in this at least one section, the substrate 102 to be folded can be guided over the entire length of the ribbon line 120. In this case, the strip lines 120 arranged over the width of the slide plate 110 can project beyond the base edge 111 over the width to a different extent, in order to avoid a collision of the strip lines 120 with the guide elements 114.
    As seen in the transport direction 103 far beyond the base edge 111 extending tape line 120 thus very far with at least one slot or step-like recess 113, the sliding plate 110 must be recessed, the existing of the sliding plate 110 and the two vanes 114 static Region of the longitudinal folding device 101 also exist as two symmetrical to a median plane 106 executed angular shells 116, which at a corresponding distance, which is perpendicular to the transport direction 103, to each other. The guide elements facing surface of the sliding plate 110 is thus the web or sheet-guiding surface of the sliding plate 110th
    Such a particularly advantageous embodiment of the invention is shown in Fig. 4. In this variant, the former 103 is designed to be split, the sliding surface 117 resulting from several parts, together with the guide element 114 formed thereon, forms an angular or cup-shaped element, which is referred to below as shell 116. Also in this embodiment, the guide elements 114 facing side of the sliding surface 117 thus the web or sheet-guiding side of the sliding surface 117th
    Two shells 116 spaced symmetrically from one another replace the former 103 resulting from a sliding plate 110 and two guide elements 114. This invention shown in FIG. 8 has the advantage that, for example, the width of the outlet opening 115 can be made variable so that these and thus the geometry of the purely static part of the longitudinal folding device 101 can be made variable or adjustable. Furthermore, such a configuration has the further advantage that the inlet-side strip line 120 can be carried out very far up to the outlet opening 115 and that in the design of the ribbon line 120 of upper band 120-1 and lower band 120-2, the substrate 102 to be folded very far into the sliding surface 117 and thus already clamped even when initiating the folding process by the ribbon cable and thus guided and controlled promoted.
