    BE2017 / 5734
    Process for stuffing brushes and brush stuffing machine
    The invention relates to a method for stuffing brushes, wherein bristle bundles, in particular one after the other, are stuffed into a bristle holder of a brush, in particular a toothbrush, by means of a stuffing tool.
    Furthermore, the invention also relates to a brush tamping machine with a holder for a bristle carrier of a brush to be stuffed with bristle bundles, with a tamping tool for stuffing bristle bundles into a bristle carrier.
    Both in the method and in the brush tamping machine, the bristle bundles to be tamped are preferably tamped one after the other and in close proximity to one another in the tamping points of a bristle holder of a brush to be produced in this way, in order to produce a bristle field of the brush consisting of several bristle bundles. Serving points are generally openings in the bristle holder into which the bristle bundles are stuffed. In order to be able to stuff the bristle bundles one after the other into the bristle holder, it is advantageous to displace bristles already stuffed into the bristle holder or even entire bristle bundles to suffice To be able to create space for a stuffing tool of a next bundle of bristles used in the stuffing in the bristle carrier.
    Brush tamping machines and also methods for stuffing brushes are known from the prior art, in which bristles or entire bundles of bristles already stuffed in the bristle carrier are moved away from a stuffing point of a next bristle bundle by means of mechanical displacement elements, which are then also referred to as bundle displacers .
    The use of mechanical displacement elements has proven itself per se, but it requires a comparatively complex and thus potentially susceptible mechanism. In addition, care must be taken to ensure that the mechanical displacement elements do not collide with the stuffing tool when stuffing the bristle bundles.
    The object of the invention is therefore a method and a bristle tamping machine
    BE2017 / 5734 to create of the type mentioned, with which these disadvantages can be avoided or at least reduced.
    To achieve this object, the means and features of the independent claim directed to the method are provided in the above-mentioned method. In particular, in order to achieve the object in the method mentioned at the outset, it is proposed that at least one bristle of at least one bundle of bristles already plugged into the bristle carrier is temporarily moved away from a plugging point and / or displaced by means of at least one fluid jet prior to plugging a further bundle of bristles into the bristle carrier which the further bundle of bristles is to be stuffed into the bristle carrier. The aim is to make room for stuffing the bundle of bristles.
    In this way it is possible to dispense with a mechanical displacement element, as is generally used in the methods and brush tamping machines known from the prior art. With a fluid jet, the bristling point of the bristle bundle to be stuffed, bristles or bristle bundles already stuffed into the bristle holder, can be temporarily and comparatively gently displaced. There is no fear of damage to the bristles thus displaced by the fluid jet.
    It should be mentioned that the bristle bundles can particularly preferably be stuffed into receiving openings of the bristle carrier which act as stuffing points. Each receiving opening of the bristle holder is preferably stuffed with at least one or exactly one bundle of bristles. At least one bristle of at least one bundle of bristles already plugged into a receiving opening of the bristle carrier can be temporarily moved and / or displaced from the receiving opening to be plugged by means of the at least one fluid jet before the plugging of another bundle of bristles into a receiving opening of the bristle carrier that is yet to be plugged.
    For example, a pulsed fluid jet can be used as the fluid jet. The use of a pulsed fluid jet can help prevent the bristles or bundles of bristles to be displaced from swinging uncontrollably on the bristle carrier.
    BE2017 / 5734
    In this way, the desired displacement of bristles already plugged into the bristle carrier can be reliably achieved by means of the at least one fluid jet.
    The fluid jet used can particularly preferably be a focused fluid jet. In this way, individual bristles or individual bristle bundles can be specifically displaced with the at least one fluid jet. It can be particularly advantageous if the fluid jet used is an ionized fluid jet. The ionized fluid jet can be generated, for example, from an ionized gas or from ionized compressed air. The use of ionized compressed air, for example, can be positive for cleaning the receiving openings on the bristle carrier. By using an ionized fluid as the basis for the fluid jet, static charging of the bristle carrier and also contamination adhering to it, such as drilling chips or grinding dust or the like, can be avoided or compensated for. In addition, dust particles adhering to the already plugged bristles can be removed particularly reliably with an ionized fluid jet, in particular with an ionized compressed air jet. For example, the at least one fluid jet can be used on the one hand to displace bristles already plugged in and on the other hand to clean the bristle carrier and in particular the bristles or bundles of bristles already plugged therein.
    Gas, but preferably compressed air, can be used to generate the fluid jet. It cannot be ruled out to generate the fluid jet from a liquid, for example from water.
    Advantageously, the fluid jet can be directed onto the bristle carrier, and here preferably onto the next step to be stuffed or the receiving opening of the bristle carrier. This is so, in particular, that when the fluid jet strikes, a pressure wave is generated, which extends in a ring around a point of impact of the fluid jet, through which at least one bristle of the tamping point to be tamped adjoining a tamping point or receiving opening for a bundle of bristles to be tamped next is laterally displaced. With lateral displacement, one can
    BE2017 / 5734 reversible, lateral deflection of the displaced bristle can be understood.
    The at least one fluid jet can be emitted from at least one nozzle of a displacement device. The at least one nozzle can be arranged or formed on a tool head of a stuffing tool. It is also possible, however, for the aforementioned nozzle or another or another nozzle of the aforementioned displacement device to be arranged or formed on a nozzle holder which is separate from the tool head of a tamping tool. It can also be advantageous if a fluid jet is emitted from a tappet channel of the tamping tool onto the holder and a bristle carrier arranged thereon. It is possible for the fluid jet to be emitted from an outlet opening into the displacement channel of a displacement device, for example the one mentioned above. In this way, separate nozzles for generating fluid jets can be dispensed with. However, it is also conceivable to combine this variant of the method with the previously described variants of the method in which fluid jets are emitted from other nozzles.
    The flexibility of the method can be increased if a dispensing position from which at least one fluid jet is dispensed depends on a position of a plugging point to be tamped on the bristle holder and / or depending on a desired displacement direction of at least one bristle to be displaced from two or more Tax items can be selected. This is possible in particular if more than one nozzle is available for delivering fluid jets, in particular in the direction of the bristle carrier. However, it is also conceivable to change the dispensing position from which at least one fluid jet is emitted, depending on a position of a plugging point or receiving opening on the bristle holder to be tamped and / or depending on a desired direction of displacement of at least one bristle to be displaced. This is conceivable, for example, if the at least one fluid jet can be emitted from position-changing nozzles of a displacement device of the brush tamping machine according to the invention.
    BE2017 / 5734
    In this context, it can also be advantageous if a plurality of existing nozzles can be activated independently of one another in order to be able to deliver fluid jets from different delivery positions as required.
    To adjust an effective intensity of the fluid jet at its point of impact, it can be advantageous if a distance between a dispensing position, for example a nozzle from which the at least one fluid jet is dispensed, and the receiving opening to be filled is changed. It is conceivable to reduce a distance between a dispensing position and the stuffing point or receiving opening to be tamped in order to increase the effective intensity of the fluid jet at its point of impact. With such an increased effective intensity, a higher displacement effect of the fluid jet can be achieved at its point of impact. If a lower intensity is required at the point of impact, a distance between the dispensing position from which the at least one fluid jet is dispensed and the filling point to be tamped can also be increased.
    A particularly good displacement effect by means of a dispensed fluid jet can be achieved if the dispensing of the at least one fluid jet is controlled as a function of a relative position of the tamping tool relative to the holder that changes when the bundles of bristles are stuffed. It is also possible to control the delivery of the at least one fluid jet as a function of a tamping speed at which the tamping tool is operated. In this context, the tamping speed can be understood to mean the tamping frequency. The stuffing frequency can be calculated from a number of bristle bundles stuffed into a bristle carrier per unit of time.
    In a variant of the method according to the invention it can be provided, for example, that delivery of the at least one fluid jet is started when the distance between the tamping tool and the holder falls short of a first, and stopped again when the distance falls below a second, smaller defined distance between the tamping tool and the holder . Specifically, it could be provided, for example, that as soon as the tamping tool is on the way in the direction of the bristle carrier positioned on the holder, which can also be a brush body, the at least one fluid jet is emitted
    BE2017 / 5734 started, for example, a nozzle is activated, and as soon as the tamping tool is closer than two millimeters to the bristle holder to be tamped, the delivery of the fluid jet is prevented, that is, a nozzle is switched off.
    In addition to a displacement of at least one bristle that has already been plugged in by means of a fluid jet, it can additionally be provided that at least one further and / or also the previously mentioned bristle plugged into the bristle carrier is displaced by means of a mechanical displacement element of a mechanical displacement device before the bundle of bristles the stuffing point on the bristle carrier, in particular in the receiving opening, is stuffed.
    The method can be further refined if a bristle displacement caused by the at least one fluid jet is monitored and the delivery of the at least one fluid jet is controlled and / or regulated depending on the bristle displacement determined in this way. A monitoring device, in particular a camera, and a corresponding control and / or regulating unit can be used to monitor the bristle displacement.
    In particular, if the receiving openings of the bristle carrier to be tamped were produced by a machining process, for example by drilling, the receiving openings to be tamped can be cleaned with the fluid jet before a bundle of bristles is plugged. Contamination, in particular dust and / or drilling chips, can be blown out of the receiving opening to be tamped by means of the at least one fluid jet.
    To solve the problem, a brush tamping machine with the means and features of the independent claim directed to the brush tamping machine is also proposed. In particular, to solve the problem, a brush tamping machine with a holder for a bristle holder of a brush to be tufted with bristle bundles, with a tamping tool for stuffing bristle bundles into a bristle holder, in particular in receiving openings of a bristle holder, and with a displacement device. According to the invention, this displacement device is for dispensing at least one fluid jet onto at least one
    BE2017 / 5734
    Bristle of a bundle of bristles already stuffed into the bristle holder.
    This has the effect that this at least one bristle is moved and / or displaced before a further bristle bundle is plugged in from a plugging point at which the further bristle bundle is to be plugged into the bristle carrier.
    Thus, with the displacement device of the brush tamping machine according to the invention, a fluid jet can be generated and emitted, with which at least one bristle that has already been stuffed into the bristle holder or possibly one or more such bristle bundles can be displaced from a plugging point to be tamped on the bristle holder before a bristle bundle is stuffed becomes. This can prevent bristles which are already stuffed and which are adjacent to the stuffing point from being sewn or damaged when the next bundle of bristles is stuffed.
    The brush tamping machine according to the invention can be set up to carry out the method according to the invention and described in detail above.
    In this way, a brush tamping machine is created in which there is no need for comparatively complex mechanical displacement elements for displacing bristles or bundles of bristles that have already been plugged in.
    The displacement device of the brush tamping machine according to the invention can comprise at least one nozzle for delivering a fluid jet. This nozzle can be arranged or formed on a tool head of the tamping tool facing the holder during tamping. However, it is also possible that the displacement device for delivering a fluid jet comprises at least one nozzle which is arranged or formed on a nozzle holder separate from the stuffing tool. Both a nozzle arranged or designed on a tool head of the tamping tool and a nozzle arranged or designed on a separate nozzle holder can preferably be oriented in the direction of the holder in order to displace at least one fluid jet, in particular a compressed air jet, in accordance with the tamping process in the direction of the holder an already stuffed bundle of bristles or one already
    BE2017 / 5734 to be able to deliver stuffed bristle.
    On the tamping tool, in particular on its tool head, a plurality of nozzles, in particular uniformly distributed around a tappet channel of the tamping tool, for dispensing fluid jets can be arranged or formed.
    In this way, the tamping tool, in particular the tool head of the
    Darning tool, act as a nozzle holder.
    Additionally or alternatively, the displacement device can also have a fluid outlet opening into the tappet channel. A fluid, in particular compressed air, can be introduced into the pusher channel from this fluid outlet, so that a fluid jet can also be emitted in the pusher channel of the tamping tool in the direction of stuffing of the bristle bundle, that is to say in the direction of the holder and a bristle carrier stretched thereon.
    It is possible for the displacement device to have a nozzle holder which is separate from a tool head, for example the one already mentioned above. This nozzle holder can for example be annular. At least two, preferably three or four, uniformly distributed nozzles can be arranged or formed on this nozzle holder. These nozzles are then also expediently aligned with the holder and a bristle carrier clamped thereon.
    In order to be able to deliver fluid jets in a targeted manner to the bristle carrier on the bristle carrier depending on a position of a stuffing point to be tamped, in particular a receiving opening, the displacer device, in particular the nozzle holder, can be mounted on a frame of the brush tamping machine in a position-changing, in particular rotatable and / or pivotable be. It is also possible to arrange one, for example the at least one already mentioned, mounted on a nozzle holder, for example the already mentioned one, in a position-changeable, in particular rotatable and / or pivotable, position. In this way, each existing nozzle, preferably independently of another nozzle of the displacement device, in its position and relative orientation to the holder and a bristle carrier clamped thereon
    BE2017 / 5734 can be changed. The aim is to be able to deliver fluid jets from different directions and to different points of impact on the holder or on the bristle carrier on the latter.
    If the brush tamping machine has at least one ionization device for ionizing a fluid which is emitted in the form of a fluid jet via the displacer device, ionized fluid jets can be dispensed via the displacer device.
    At this point, it should be mentioned that the displacement device can be set up to deliver a gas, in particular to deliver compressed air or compressed air jets, but in principle also to deliver a liquid jet to displace bristles and / or bundles of bristles that have already been plugged into the bristle carrier. Preferably, however, compressed air in the form of possibly ionized compressed air jets is emitted via the displacement device.
    In order to avoid an uncontrolled oscillation of bristles or bundles of bristles on the bristle carrier when they are displaced by means of at least one fluid jet, the displacer device can be designed to emit pulsed fluid jets. The brush tamping machine can have an electronic control and / or regulating unit and / or also a mechanical control and / or regulating unit for controlling and / or regulating the displacement device. With such a device, the displacement device and in particular the delivery of fluid jets can be controlled or regulated as a function of a distance that changes during the tamping between the tamping tool and the holder and / or as a function of a tamping speed or a tamping frequency of the tamping tool.
    The brush tamping machine can also have a monitoring device, in particular a camera, for monitoring a bristle displacement caused on the bristle carrier by the displacement device. Furthermore, the displacement device can be controlled and / or regulated by means of a control unit, for example the control and / or regulating unit already mentioned, depending on the observed bristle displacement.
    BE2017 / 5734
    In addition to the displacement device, which could also be referred to as a pneumatic displacement device, the brush tamping machine can additionally have a mechanical displacement device with at least one mechanical displacement element. With this mechanical displacement element, displacement of at least one bristle plugged into a bristle carrier held ready on the holder can be supported.
    Several embodiments of the invention are described in more detail below with reference to the drawing. They show in a partially highly schematic representation:
    Figure 1 is a perspective view of a brush tamping machine according to the invention, which has a displacement device with an annular nozzle holder with a plurality of compressed air nozzles directed towards the bristle field of a bristle holder provided, one or more nozzles for dispensing one depending on the direction in which the bristles of the bristle field are to be displaced Fluid jet, here a compressed air jet, are activated.

    5 shows a perspective view of a further approximately conical tool head of a tamping tool according to the invention, the tool head having a plurality of connections accessible from the outside and a plurality of channels running through the tool head with outlet openings directed radially slightly outwards with respect to a longitudinal axis of a plunger channel as nozzles of a displacement device.
    In the following description of various embodiments of the invention, elements that correspond in terms of their function receive corresponding reference numbers even with a different design or shape.
    FIG. 1 shows a brush tamping machine, generally designated 1, on which brushes 2 can be produced. The brush tamping machine 1 has a holder 3 for a bristle holder 5 of the brush 2 to be produced, which is to be tufted with bristle bundles 4. Furthermore, the brush tamping machine 1 is provided with a tamping tool 6, which is set up for tamping bundles of bristles 4 into tamping points 7 of the bristle holder 5. In the exemplary embodiment shown in FIG. 1, the bristle bundles 4 are stuffed into receiving openings 7 of the bristle holder 5, which serve as stuffing points 7 of the bristle holder 5.
    These receiving openings 7 were created in an upstream process step or in the manufacture of the bristle carrier 5.
    Furthermore, the brush tamping machine 1 has a displacement device 8, which is set up to emit a fluid jet onto a bristle carrier 5 arranged on the holder 3. By means of this fluid jet, at least one bristle 4a which has already been introduced into the bristle carrier 5 can be displaced into a receiving opening 7 to be tamped before a further bristle bundle 4 is plugged.
    The displacement device 8 comprises a plurality of nozzles 9 which, in the exemplary embodiment of the brush tamping machine 1 according to FIG. 1, are arranged on a nozzle holder 10 separate from the tamping tool 6
    BE2017 / 5734 are trained. The nozzle holder 10 has an annular shape. Each of the nozzles 9 provided on the nozzle holder 10 is oriented in the direction of the holder 3. The ring-shaped nozzle holder 10 delimits a material-free interior through which the stuffing tool 6 fits and can be moved when its lifting-like stuffing movements are carried out.
    FIGS. 2 to 5 each show a tool head 11 of a tamping tool 6, which could be used in the brush tamping machine 1 according to FIG. 1. At least six nozzles 9 are arranged or formed on the tool heads 11 shown in FIGS. 2 to 5, each of which faces a holder 3 of a brush tamping machine 1 in the use position. The nozzles 9 are supplied with fluid, here with compressed air, via nozzle connections 12.
    The nozzles 9 arranged on the tamping tool 6 are arranged or formed in a uniform manner around a pusher channel 13 of the tamping tool 6, in which a pusher tongue 14 for moving bristle bundles 4 is moved into the bristle carrier 5. The displacement device 8 also comprises a fluid outlet 15 opening into the pusher channel 13, via which a fluid jet can be emitted from the pusher channel 13 of the tamping tool 6 in the direction of stuffing of the bristle bundle 4.
    According to FIG. 1, the nozzle holder 10 already mentioned is an annular nozzle holder which is arranged separately from the tool head 11 of the tamping tool on a frame 16 of the brush tamping machine 1. A plurality of nozzles 9, here compressed air nozzles 9, which are arranged uniformly on the nozzle holder 10 and are directed onto the holder 3 of the brush tamping machine 1 are arranged on the annular nozzle holder 10. The position of the nozzle holder 10 shown schematically in FIG. 1 can be changed as part of the displacement device 8 in relation to the holder 3 and a bristle carrier 5 clamped thereon. For this purpose, the nozzle holder 10 is rotatably and / or pivotably mounted on the frame 16 of the brush tamping machine 1. In addition, the nozzle holder 10 can also be moved linearly on the frame 16, for example in order to change a distance between the holder 3 and the nozzle holder. The individual nozzles 9, in turn, can be changed in position on the nozzle holder 10, in particular rotatable
    BE2017 / 5734 and / or swivel mounted.
    In order to be able to ionize the fluid emitted in the form of fluid jets, here compressed air, the brush tamping machine 1 has an ionization device (not shown in any more detail). This can be integrated, for example, in a compressed air supply to the brush tamping machine 1.
    The displacement device 8 is set up to emit pulsed fluid jets. Furthermore, the brush tamping machine 1 has an electronic control and / or regulating unit and / or a mechanical control and / or regulating unit for controlling and / or regulating the displacement device 8. With this control and / or regulating unit, control and / or regulation of the displacement device can be carried out, for example, as a function of a distance that changes during the tamping between the tamping tool 6 and the holder 3 and / or as a function of a tamping speed of the tamping tool 6.
    In an embodiment of the brush tamping machine 1 according to the invention, which is not shown separately in the figures, the tamping machine 1 is provided with a monitoring device, which is set up, for example, using a camera to monitor a bristle displacement 5 caused by the displacement device 8 on the bristle holder 5. The displacement device 8, that is to say a delivery of at least one fluid jet by means of the displacement device 8, can be controlled and / or regulated depending on the observed bristle displacement, for example by means of the control and / or regulating unit already mentioned.
    In addition to the displacement device 8, which can also be referred to as a pneumatic displacement device 8, a mechanical displacement device with at least one mechanical displacement element can be used for the displacement of at least one bristle 4a plugged into a bristle carrier 5 provided on the holder 3.
    The tool head 11 of the stuffing tool 6 shown in FIG. 2 faces on the outside
    BE2017 / 5734 a total of six evenly distributed nozzles 9 around its tappet channel 13.
    The tool head 11 shown in FIG. 3 of a tamping tool 6 that can be used with the brush tamping machine 1 according to FIG. 1 is provided on the outside with a nozzle attachment 17. The nozzle attachment 17 is pushed onto the pyramid-shaped tool head 11 and has channels 18 on the inside which are provided with outlet openings 20 which form the nozzles 9 of the displacement device 8. An outside of the tool head 11 according to FIG. 3 forms a channel wall 19 of the respective channels 18 and closes the channels 18 laterally. For each of the channels 18, an externally accessible nozzle connection 12 is provided on this tool head 11.
    The tool head 11 according to FIG. 4 has neither attached nozzles 9 nor a nozzle attachment 17. Rather, the nozzles 9 of this tool head 11 are formed by channels 18 which pass through the tool head 11. Each of these channels 18 has an inlet opening which serves as a nozzle connection 12. Via this nozzle connection 12, the channels 18 can be supplied with a fluid, here with compressed air, in order to generate the fluid jets for displacing bristles 4a and / or bristle bundles 4 on the bristle carrier 5.
    The tool head 11 according to FIG. 5 has approximately a conical shape and is also penetrated by a plurality of channels 18. Outlet openings 20 of these channels 18 are directed radially outward to a longitudinal axis of the tool head 11. This tool head 11 also has a plurality of nozzle connections 12, via which the channels 18 and their outlet openings 20, which then function as nozzles 9, can be supplied with compressed air.
    It should be emphasized that each of the tool heads 11 shown in FIGS. 2 to 5 can be used on the brush tamping machine 1 shown in FIG. 1. It is conceivable to use a separate nozzle holder 10 with a plurality of nozzles 9 on the brush tamping machine 1 according to FIG. 1 in addition to a tool head 11 with at least one nozzle 9, as shown in FIG.
    BE2017 / 5734 With the previously described brush tamping machine 1, the method described below for tamping brushes 2 can be carried out. It is provided that bundles of bristles 4 are stuffed by means of the stuffing tool 6, in particular one after the other, into stuffing points 7 of a bristle holder 5 of a brush 2 to be produced. In the present exemplary embodiment of the bristle carrier 5, the stuffing points 7 are each formed as a bundle of bristles 4 as receiving openings 7. This brush 2 can be, for example, a toothbrush or a brush head of a toothbrush. However, it is also conceivable to fix the bristle carrier 5 to a brush body as soon as it is stuffed with bristle bundles 4 to produce a bristle field of the bristle carrier 5.
    In a manner known per se, the stuffed bristle bundles 4 can be fastened in the bristle carrier 5 by means of anchors and / or loops.
    In the method according to the invention it is provided that at least one bristle 4a already plugged into the bristle carrier 5 adjacent to the receiving opening 7 to be next to be tufted or an entire bristle bundle 4 before at least one next bristle bundle 4 is tucked into the receiving opening 7 of the bristle carrier 5 to be tamped of a fluid jet is temporarily displaced in order to make room for the bristle bundle 4 to be stuffed.
    Depending on requirements, an already plugged-in bristle bundle 4 or an already plugged-in bristle 4a can be displaced by means of a pulsed, a focused and / or ionized fluid jet. In principle, all suitable fluids can be used for displacement. However, compressed air is preferably used to generate the fluid jet.
    The fluid jet is directed onto the bristle carrier 5 and here preferably onto the receiving opening 7 of the bristle carrier 5 to be filled next. This is done in such a way that when the fluid jet strikes, a pressure source that extends in a ring shape around a point of impact of the fluid jet is generated, through which at least one receiving opening 7 to be tamped is already
    BE2017 / 5734 plugged bristle 4a or an already plugged bristle bundle 4 is laterally displaced from the receiving opening 7 to be plugged. In this way, sufficient space is created to stuff the next bundle of bristles 4 into the receiving opening 7 that is to be filled next. It should be pointed out that the displacement of an already plugged-in bristle bundle 4 or at least one already plugged-in bristle 4a takes place in accordance with the stuffing process. The tamping speed, a tamping frequency and the displacement caused by at least one bristle 4a or one bristle bundle 4 can have a particular influence.
    The at least one fluid jet is emitted from a nozzle 9 of the displacement device 8 of the bristle tamping machine 1. One nozzle 9 can be arranged or formed on a tool head 11, as shown in FIGS. 2 to 5, of a tamping tool 6 of the brush tamping machine 1. As shown in FIG. 1, it is also possible for a nozzle 9, from which at least one fluid jet is emitted, to be arranged or formed on a nozzle holder 10 which is separate from the tool head 11 of the stuffing tool 6. In a further embodiment of the method according to the invention it is provided that a fluid jet is emitted from the pusher channel 13 of the tamping tool 6.
    Depending on which of several stuffing points 7 or receiving openings 7 are to be tamped on a bristle carrier 5 provided, a delivery position from which at least one fluid jet is delivered to the bristle carrier 5 can be made from two or more different delivery positions, i.e. the positions at which the nozzles 9 are arranged can be selected. However, it is also possible to change the delivery position from which at least one fluid jet is delivered. For this purpose, position-changing nozzles 9 can be advantageous. The previously described selection of the delivery position from a plurality of delivery positions can also take place as a function of a desired displacement direction, in which the at least one bristle 4a or also a plurality of bristles 4a or also entire bristle bundles 4 which have already been stuffed into the bristle carrier 5 are to be displaced.
    The required effective intensity of the fluid jet at its point of impact
    BE2017 / 5734, it is possible to vary a distance between a delivery position from which the at least one fluid jet is delivered and the receiving opening 7 to be filled. If this distance is reduced, the intensity of the fluid jet at its point of impact increases. If the distance is increased, the generated fluid jet strikes the impact point with a lower intensity, so that its displacement effect is then correspondingly smaller.
    The double arrow 21 shown in FIG. 1 illustrates the lifting movement which the tamping tool 6 carries out when the bristle bundles 4 are plugged in relative to the holder 3 and a bristle carrier 5 which is clamped thereon and is bristled with bristles 4a and bristle bundles 4. In this case, it may be expedient to control or regulate the delivery of the at least one fluid jet depending on a relative position of the tamping tool 6 to the holder 3 that changes when the bristle bundles 4 are tamped and also on a tamping speed of the tamping tool 6. In this way, delivery of the at least one fluid jet can be started when the distance between the tamping tool 6 and the holder 3 falls below a first defined distance. If the distance between the tamping tool 6 and the holder 3 falls below a second, defined distance, for example when the tamping tool 6 has approached the holder 3 and the bristle carrier 5 clamped thereon, the delivery of the fluid jet is stopped. For this purpose, the one or more nozzles 9 are then deactivated.
    In addition to the previously described displacement of at least one bristle 4a by means of at least one fluid jet, in particular by means of a compressed air jet, displacement of a bristle 4a, which is already plugged into the bristle carrier 5, can also be carried out by means of a mechanical displacement element of a mechanical displacement device, which is not shown separately in the figures respectively. This mechanical displacement then also takes place before the bristle bundle 4, which is to be plugged in next, is plugged into the bristle carrier 5.
    If necessary, the delivery of the at least one fluid jet can also be controlled as a function of a bristle displacement on the bristle carrier 5 to be tufted, which can be monitored and ascertained by means of a monitoring device
    BE2017 / 5734 and / or regulated.
    In addition to the tamping tool 6, the holder 3 and the nozzle holder 10, a pivotable bristle magazine 22 with a supply of bristles 4a and a pivotable bundle divider 23 are also arranged on the frame 16 of the brush tamping machine 1. By means of the bundle divider 23, which is designed here as a circular arc divider, a bristle bundle 4 can be removed from the supply of bristles 4a of the bristle magazine 22 in a manner known per se. For this purpose, the bundle divider 23 is moved past a front of the bristle magazine 22. A defined number of bristles 4a reaches a compartment notch 24 of the bundle divider 23, is combined there to form a bristle bundle 4 and is finally transferred to the tamping tool 6. Together with a fastening anchor, which can be fed to the tamping tool 6 by means of an anchor feed device 25, the bundle of bristles 4 introduced into the tamping tool 6 is then pushed with the plunger tongue 14 through the tappet channel 13 of the tamping tool 6 into a correspondingly positioned tamping point 7 on the holder 3 stretched bristle carrier 5 stuffed and anchored there. One of the receiving openings 7 for bristle bundles 4 in the bristle carrier 5, which has already been mentioned several times, serves here as the plugging point 7.
    In order to be able to gradually bring the plurality of receiving openings 7 on the bristle carrier 5 into a relative position to the tamping tool 6 required for tamping bristle bundles 4, the holder 3 is arranged on a movable holding device 26 on the frame 16 of the brush tamping machine 1.
    The method according to the invention and the brush tamping machine 1 according to the invention are proposed as an improvement in the field of tamping brushes. These provide that at least one bristle 4a already stuffed into a bristle carrier 5 of a brush 2 is displaced by means of a, preferably focused, fluid jet before the plugging in of a further bristle bundle 4, in order to provide the space required for plugging the bristle bundle 4 into a not yet stuffed one To create a stuffing point 7 of the bristle carrier 5.
