    Method for setting a transport step width of a wire driver and tamping machine
    The invention relates to a method for setting a transport step width of a wire carrier of a feed device for anchor wire on a tamping machine, which is set up for the production of brushes or brooms.
    Furthermore, the invention also relates to a tamping machine for the production of brushes or brooms, which comprises a tamping tool and a feed device with which anchor wire for anchoring bundles of bristles in a bristle carrier can be fed to the tamping tool.
    Such methods and devices are known in practice in different embodiments.
    When producing different brushes or brooms, it may be necessary to provide wire anchors of different lengths for anchoring the bristle bundles in the bristle holder of the brush or broom to be produced. The necessary adjustment of the anchor lengths of the wire anchors is carried out, for example, by changing or setting a transport step width of a wire carrier of a feed device. A change in the anchor length may not only be necessary when changing the type of brush or broom to be produced, but even when plugging different receiving holes in a bristle holder of a brush or broom.
    So far, it has been comparatively complex to set the desired anchor length. For example, it is known to change settings on the tamping machine that affect the anchor length, then one
    BE2018 / 5536
    Run a test run in order to then measure the wire anchors manufactured with a modified anchor length. The wire anchors are measured to determine whether the set anchor length is within the required tolerances or not. Only when this comparatively complex check has been carried out is it possible to continue with the actual tamping of the bristle carrier.
    The object of the invention is now to provide a method and a tamping machine of the type mentioned at the outset which, if appropriate, simplify adaptation of the anchor lengths even during a tamping process and thus increase the flexibility in the production of brushes or brooms.
    In the method mentioned at the outset, this object is achieved by the means and features of the independent claim directed to such a method. In particular, it is proposed to solve this problem that the transport step width is set or changed and, after the setting or change, is determined at least indirectly with a sensor of the tamping machine. This is done with the aim of inferring an anchor length of wire anchors which is related to the transport step width and which is fed with the feeding device to a tamping tool of the tamping machine in order to plug bristle bundles into a bristle carrier and anchor them there.
    In this way it is possible to draw conclusions about the set anchor length at least indirectly via a determination of the transport step width carried out in the tamping machine. This means that there is no need to measure the wire anchor separately. This speeds up an adaptation of the brush tamping machine to the production of other brushes or brooms or an adaptation of the required anchor lengths even within one
    BE2018 / 5536
    Darning a broom or a brush.
    It can be advantageous if the transport step width determined by the sensor, which correlates or even corresponds to the length of the wire anchors supplied, and / or a target transport step width is displayed on a display device of the tamping machine.
    In particular, if both the transport step width determined by the sensor and a target transport step width that is required for a specific production step are displayed on the display device of the tamping machine, it is possible to manually adjust the anchor length by changing the transport step width. In addition, the display of both the determined transport step width and the target transport step width enables the settings made on the tamping machine to be checked.
    The method can be carried out particularly conveniently if the transport step width, preferably under constant determination of the set transport step width or the changing transport step width, is adjusted, in particular automatically, until the transport step width determined by the sensor corresponds to the target transport step width. In this variant of the method, for example, the tamping machine can specify the target transport step. Depending on the target transport step width, the transport step width of the wire carrier is then changed until the determined transport step width and the target transport step width match. The change in the transport step width of the wire driver can preferably be carried out automatically, but in principle also manually.
    BE2018 / 5536
    At this point it should be mentioned that the target transport steps can be taken from an instruction memory of the tamping machine. In the instruction memory, certain target transport steps can be assigned to individual brush or broom types and / or. A corresponding selection or selection of the brush or broom types can then be used to read out an assigned target transport step size and, for example, to transfer it to the display device of the stuffing device and display it there. Depending on the desired transport step width, the transport step width of the wire carrier can then be adjusted manually or preferably also automatically.
    In a variant of the method it is provided that the transport step width is set between two successive tamping processes. This makes it possible to fill a bristle holder with wire anchors of different lengths.
    In order to determine the transport step width at least indirectly, in one embodiment of the method a deflection of the wire driver, in particular if it is designed as a wire feed lever, can preferably be determined or measured directly with the sensor. Since the transport step width is related to the deflection movement of the wire driver, it is particularly easy and reliable to draw conclusions about the transport step width.
    For this purpose, a swiveling or deflecting movement of the wire driver, in particular of the wire feed lever, can be transmitted to the sensor. If the sensor is designed as a rotary encoder, that is to say as a sensor for the angle of rotation, the deflection of the wire carrier and thus the transport step width can be particularly easily and directly in this way
    Determine BE2018 / 5536. Such encoders are also referred to as incremental encoders or incremental encoders.
    The object mentioned at the outset is also achieved by a tamping machine for the production of brushes or brooms of the type mentioned at the outset, which has the means and features of the independent claim which is directed to such a tamping machine. To solve the problem, it is proposed in the aforementioned tamping machine in particular that the feed device has a wire driver and the tamping machine has a sensor, the wire driver being configured to feed the anchor wire to the tamping tool with an adjustable and / or variable transport step width, and the sensor is set up to at least indirectly determine the transport step width and thus an anchor length of wire anchors obtained from the supplied anchor wire.
    In this way, a tamping machine for the production of brushes or brooms is created, with which the armature length of the wire anchors fed to the tamping tool with the feed device can be adjusted by changing, adapting or adjusting the transport step width of the wire driver of the feed device. Furthermore, an at least indirect determination of the set transport step width can be made on the tamping machine according to the invention via its sensor. Since the transport step width with which the armature wire is fed to the tamping tool is related to the armature length, the transport step width determined with the sensor allows a conclusion and / or a determination of the armature length of the wire anchors finally supplied to the tamping tool.
    In a preferred embodiment of the tamping machine, it is provided that the feed device has an adjusting link, a
    BE2018 / 5536
    Link guide and has a wire feed lever as a wire driver. The setting link is assigned to the wire feed lever and can be moved along the link guide. A relative position of the setting link on the link guide then defines a swivel angle range of the wire feed lever and thus the transport step width of the wire driver. The pivoting angle range of the wire feed lever can thus be changed by changing the relative position of the setting link on the link guide. The larger the swivel angle range of the wire feed lever, that is, the area in which the wire feed lever can be pivoted back and forth between two dead centers as a wire driver, the greater the transport step width.
    In this case, the sensor of the tamping machine can be set up to determine the relative position of the setting link on its link guide and thereby to determine the transport step width. In this way, the relative position of the setting link on its link guide finally allows conclusions to be drawn about the anchor length of the wire anchors supplied with the feed device. This is done without having to separately measure the wire anchors that have been cut to length.
    However, it is also possible for the sensor to be set up to determine and / or measure a deflection of the wire driver, in particular the wire feed lever, and thereby to determine the transport step width. For this purpose, it can be particularly expedient to use a rotary encoder as a sensor, that is to say a sensor with which the angle of rotation can be determined. Such encoders are also referred to as incremental encoders.
    If a fixed shaft or axis is provided around which the
    BE2018 / 5536
    Wire driver, in particular the wire feed lever, is pivotally mounted, the sensor, in particular as a rotary encoder, can be arranged on the fixed shaft or axis. The movement of the wire carrier, in particular of the wire feed lever, can be transmitted to the sensor via at least one transmission element which is connected both to the sensor and to the wire carrier and can be determined by the latter.
    The sensor, in particular if it is designed as a rotary encoder, can also be arranged on a housing or frame of the tamping machine. This is particularly the case when the sensor is connected to a rotatably mounted shaft of the wire driver, in particular the wire feed lever. The movement of the wire driver, which is then connected in a rotationally fixed manner to its shaft, can be transmitted particularly easily and directly via the shaft to the sensor, which is preferably designed as a rotary encoder. The sensor can then determine the deflection of the wire driver or the resulting rotation or swivel angle of the shaft. The transport step width can then be derived from the deflection of the wire carriers.
    The tamping machine can have a display device coupled to the sensor. The transport step width determined by the sensor can be displayed on this display device. Furthermore, it is possible to display on the display device a desired transport step width and / or a relative position, for example the aforementioned, determined by the sensor, for example of the setting backdrop already mentioned.
    It is also possible for the tamping machine to have a scale for displaying the relative position and / or the transport step width. The use of a scale can be particularly useful with a manual
    BE2018 / 5536
    Setting the transport increment may be advantageous.
    The link guide can be designed as a spindle. In the case of a link guide designed as a spindle, the setting link can be arranged or formed on a spindle slide of the spindle. In this way, the setting link, which is assigned to the wire feed lever serving as a wire driver, can be axially displaced along the spindle by rotating the spindle, which serves as a link guide. The transport increment of the wire carrier can be changed by the axial displacement of the setting link on the link guide.
    The sensor of the tamping machine can be a distance sensor, a linear sensor, a hollow shaft sensor, a rotary encoder or an incremental encoder. In particular when using a spindle as a link guide, the use of a hollow shaft sensor, a rotary encoder or an incremental encoder as a sensor of the tamping machine is appropriate.
    As already explained above, the sensor can be connected at least indirectly to the wire driver, in particular to the wire feed lever, in order to transmit the deflection movement of the wire driver to the sensor and also to determine the transport step width therefrom. For this purpose, the sensor can be connected to the wire driver via at least one transmission element.
    The wire feed lever is particularly preferably a two-leg wire feed lever. This two-leg wire feed lever can have a first leg and a second leg. A wire contact surface can be formed on a free end of the second leg. The anchor wire to be supplied can rest against this wire contact surface in the use position. The
    BE2018 / 5536
    The wire contact surface is preferably convexly curved, so that when the wire feed lever pivots, the wire contact surface can be moved through an imaginary fixed point at which the wire contact surface contacts the anchor wire in the position of use.
    The setting link is preferably connected to the first leg of the wire feed lever when using a two-leg wire feed lever.
    The wire feed lever, in particular when it is designed as a two-leg wire feed lever, can have a, preferably curved, guide link on its first leg. A guide element, for example a sliding block, can be arranged in this guide link. The setting link and / or a force transmission element of a wire feed drive of the tamping machine can be articulatedly connected to the wire feed lever via the guide element.
    It may be expedient if a radius of curvature of the guide link corresponds to a length of the force transmission element of the wire feed drive and / or if the force transmission element is articulated both on the wire feed drive and on the guide element. In this way, a linear, alternating movement of the wire feed drive can be translated into a pivoting movement of the wire driver via the force transmission element.
    In this way, on the one hand a feed movement of the wire feed drive can be transmitted to the wire feed lever functioning as a wire driver and on the other hand a change in the
    BE2018 / 5536
    Change the swivel angle range of the wire feed lever as desired by changing the relative position of the setting link on the wire feed lever.
    When using a wire driver designed as a wire feed lever, in particular as a two-legged wire feed lever, it may be expedient if a so-called freewheel lever is assigned to the wire driver. This freewheel lever can preferably be pivotally mounted and / or pressurized. The freewheel lever, in cooperation with the wire driver, enables the anchor wire to be conveyed in only one direction, i.e. towards the tamping tool of the tamping machine. When the wire feed lever is pivoted back against the conveying direction of the armature wire, the freewheel lever can prevent the armature wire from being pulled back against the conveying direction by the return movement of the wire feed lever. It can be advantageous if a transport plane, within which the anchor wire can be fed to the tamping tool, is arranged between the wire feed lever and the freewheel lever. The freewheel lever and the wire feed lever serving as a wire driver are thus arranged on two opposite sides of the anchor wire when the anchor wire is in the position of use.
    The tamping machine can have an adjusting device for changing the transport step width of the wire carrier. In particular, this adjusting device can be set up to change the relative position of the adjusting link on the link guide. It can be expedient if the adjusting device comprises an automatic and / or a manual actuator. In a variant of the tamping machine, the actuator is connected to a spindle serving as a link guide. The function of such a spindle was
    BE2018 / 5536 already described above. The actuator can rotate the spindle. As a result, the spindle slide with the adjusting link can be adjusted axially relative to the wire driver and the transport step width of the wire driver, in particular the swivel angle range of the wire feed lever, can be adjusted in order to finally change the anchor length of the supplied wire anchors.
    The tamping machine can also have a control unit which can be coupled or coupled to an actuator of the tamping machine and / or to the sensor, for example the one already mentioned above. For this purpose, a signal connection, in particular a wire-bound signal line, can be formed between the control unit and the sensor. This control unit can be set up not only to control the transport step width, but also to regulate it, preferably as a function of the data determined with the sensor, in particular the transport step widths determined with the sensor. The control unit can consequently also be referred to as a control unit or evaluation unit.
    The tamping machine can also include an input interface for inputting a transport step size to be set and / or an instruction memory. Certain transport step widths and / or swivel angle ranges and / or relative positions of the setting link can be assigned to individual brush and / or broom types in the instruction memory. Since a transport step width corresponds to a certain anchor length of the supplied wire anchors, an anchor length can also be set with the help of the data stored in the instruction memory. Of course, it is also possible to store defined anchor lengths in the instruction memory and to assign them to certain types of brooms or brushes. So it is possible by selecting a specific brush or broom type from the
    BE2018 / 5536
    To get the necessary information for setting the transport increment by using the instruction memory.
    Furthermore, the tamping machine, in particular using the control unit already mentioned, can be set up to automatically make the necessary settings for the transport step widths after selection of a specific type of broom or brush. In this case, it may be expedient if the instruction memory is designed as a program memory in which entire production programs with individual anchor lengths, transport step widths, swivel angle ranges and / or relative positions of the setting link are stored for individual brush or broom types.
    In this case, the data stored or storable in the instruction memory can be displayed on a display device of the tamping machine, for example on the aforementioned device. In this way, checking the settings made is simplified for an operator of the tamping machine. Furthermore, it can be expedient if the data stored in the instruction memory and / or the program memory can be read out and processed by a control unit of the tamping machine, for example the already mentioned above, for the automatic setting of the transport step width.
    Here, the tamping machine, in particular by its control unit and / or by its adjusting device, can be set up to independently adapt a required transport step width after selection of a brush or broom type to be processed; this, for example, via an automatic setting of the relative position of the
    BE2018 / 5536
    Setting gate and thus the swivel range of the wire feed lever as a function of the data, instructions and / or programs stored in the instruction memory or in the program memory.
    The tamping machine can have a cutting device. With the help of this cutting device, individual wire anchors can be cut to length from the anchor wire fed with a defined transport step width. A length of the wire anchors cut to length can correspond to the set transport increment of the wire driver.
    It is also possible that the tamping machine has a bundle compartment device with a material box for receiving loose bristle filaments. With the help of the bundle compartment device, individual bristle bundles can be divided from the supply of loose bristle filaments that can be kept in the material box of the tamping machine and fed to the tamping tool of the tamping machine. For this purpose, the bundle compartment device has at least one bundle compartment notch on a side facing the material box.
    With the help of a ram tongue of the tamping tool, the bristle bundles can be plugged into a receiving hole of a bristle carrier provided, together with a previously supplied wire anchor which has been cut to length from the anchor wire, for example with the aid of the cutting device. The bristle carrier can be, for example, a brush body or a broom body.
    For the sake of completeness, it should be mentioned that the previously described tamping machine can of course be set up to carry out the method according to one of claims 1 to 4.
    BE2018 / 5536
    The invention will now be described in more detail using exemplary embodiments, but is not restricted to these exemplary embodiments. Further exemplary embodiments result from a combination of the features of individual or a plurality of protection claims with one another and / or in combination with individual or a plurality of features of the exemplary embodiments.
    Fig. 1 shows a highly schematic representation of a first embodiment of a brush tamping machine according to the invention, the wire driver is designed as a two-legged wire feed lever.
    FIG. 2 shows a highly schematic representation of a further tamping machine, which is almost identical in construction to the tamping machine according to FIG. 1, in which a rotary encoder is provided as a sensor, with which a deflection of the two-legged wire feed lever can be measured and a transport step width of the wire feed lever can thereby be determined.
    Because of their largely identical structure, the same description was given for the description of the two tamping machines shown in the figures for elements that have the same function, even if the design or shape is different. At least with regard to matching elements, the following description can consequently be read logically on both tamping machines shown in FIGS. 1 and 2, even if the text specifically refers to only one of the two tamping machines.
    Both figures each show a tamping machine, generally designated 1, for the production of brushes or brooms. The tamping machine 1 has a tamping tool 2 and a feed device 3. With the feed device 3 anchor wire 4 can
    BE2018 / 5536
    Feed tamping tool 2 with variable transport step width. With the aid of the tamping tool 2, a bundle of bristles together with a wire anchor obtained from the supplied anchor wire 4 can be stuffed into a bristle carrier 5 held ready and fastened to it by anchoring.
    The feed device 3 of both tamping machines 1 shown in the figures each has a wire driver 6. The tamping machines 1 are provided with a sensor 7. The wire carrier 6 is set up to feed the armature wire 4 to the tamping tool 2 with an adjustable transport step width. The transport step width of the wire carrier 6 can be determined at least indirectly using the sensor 7. Since the transport step width correlates with the length of the wire anchors supplied, which can be cut to length by the anchor wire 4, the length of the wire anchors can be deduced with the aid of the sensor 7 and by determining the transport step width of the wire driver 6.
    1 and 2 show that the feed device 3 of the respective tamping machine 1 has an adjusting link 8, a link guide 9 and as a wire driver 6 a wire feed lever 10.
    The setting link 8 is assigned to the wire feed lever 10 and is displaceable along the link guide 9. A relative position of the setting link 8 on the link guide 9 defines a swiveling angle range of the wire feed lever 10, a transport step width of the wire driver and thus finally also the anchor length of the wire anchors which are fed to the tamping tool 2.
    The sensor 7 of the tamping machine 1 shown in FIG. 1 is for determining the relative position of the setting link 8 on it
    BE2018 / 5536
    Set guide 9 and thereby set up to determine the transport step width of the wire driver 6 designed as a wire feed lever 10.
    In the tamping machine 1 shown in FIG. 2, the sensor 7 is set up to determine a deflection or swivel position of the wire feed lever 10. The transport step width can be deduced from the deflection of the wire feed lever 10. For this purpose, the sensor 7 in the tamping machine 1 shown in FIG. 2 is designed as a sensor for rotation angles, for example as a rotary encoder or incremental encoder.
    Each of the tamping machines 1 also has a display device 11 coupled to the sensor 7. On this display device 11 can be determined by the respective sensor 7 transport steps, a desired transport step to be set and / or, in particular in the tamping machine 1 shown in Figure 1, a relative position of the adjusting link 8 determined by the sensor 7 on the link guide 9 and of course also others Data are displayed. In an embodiment of the tamping machine 1, which is not shown in the two figures, a scale is also provided for displaying the relative position and / or the transport step width.
    In the present exemplary embodiments, the link guide 9 is designed as a spindle 12. The respective setting link 8 is arranged or formed on a spindle slide 13 which can be displaced along a rotation of the spindle 12.
    In the present example of the tamping machine 1 according to FIG. 1, the sensor 7 is a hollow shaft sensor, a rotary encoder or an incremental encoder which, via the rotation of the spindle 12, points to the relative position of the
    BE2018 / 5536
    Setting backdrop and thus a change in the transport step width. The sensor 7 and the display device 11 are combined in a measuring unit 14.
    As already mentioned above, the sensor 7 of the tamping machine 1 according to FIG. 2 is a rotary encoder, that is to say a sensor for determining angles of rotation. For this purpose, the sensor 7 of the tamping machine 1 according to FIG. 2 is arranged on a fixed shaft or axis 39, about which the wire feed lever 10 is pivotably mounted. The pivoting movement of the wire feed lever 10 can be transmitted to the sensor 7 designed as a rotary encoder via transmission elements 40 connected to the wire feed lever 10 on the one hand and to the sensor 7 on the other hand. The sensor 7 can thus determine the deflection of the wire feed lever 10 so that the transport step width of the feed device 3 can be determined therefrom.
    In both tamping machines 1 shown in the figures, the respective wire feed lever 10 is a two-leg wire feed lever which has a first leg 15 on one side of its pivot point 18 and a second leg 16 on the other side of its pivot point 18. A wire contact surface 17 is formed at a free end of the second leg 16. The wire contact surface 17 is convexly curved and can, for example, have the shape of a cylindrical jacket section, the radius of which corresponds to the distance of the pivot point 18 of the wire feed lever 10 from a transport plane, which is reduced by half the thickness of the supplied anchor wire, in which the anchor wire 4, using the feed device 3, corresponds to the tamping tool 2 can be supplied.
    In the tamping machines 1 shown in the figures, the respective setting link 8 is at least indirectly connected to the first leg 15 of the
    BE2018 / 5536
    Wire feed lever 10 connected. The respective wire feed lever 10 has in its first leg 15 a curved guide link 19, in which a guide element 20, here a sliding block 20, is arranged. The setting link 8 and a force transmission element 21 of a wire feed drive 22 of the tamping machine 1 both in FIG. 1 and in FIG. 2, which is designed here as a deflecting rod, are connected via this guide element 20 to the first leg 15 of the wire feed lever 10.
    A radius of curvature of the guide links 19 of the tamping machines 1 shown in the figures corresponds in each case to a length of the force transmission element 21 of the wire feed drive 22. The force transmission element 21 is articulated both on a wire feed actuator 22a of the wire feed drive 22 and on the guide element 20. In this way, a linear, alternating movement of the wire feed actuator 22a can be translated into a pivoting movement of the wire driver 6 via the force transmission element 21, which is articulated on both sides.
    1 and 2 each illustrate that a main direction of extension of the adjusting link 8 is aligned transversely and in sections even at right angles to a main direction of extension of the guide link 19 of the wire driver 6 designed as a wire feed lever 10.
    In both tamping machines 1, the wire feed lever 10, which acts as wire driver 6, is assigned a pivotably mounted and also pressurized freewheel lever 23. A transport plane, within which the anchor wire 4 can be fed to the tamping tool 3, lies between the wire feed lever 10 and the freewheel lever 23. With the aid of a compression spring 25 arranged on a counter-holder 24
    BE2018 / 5536, the freewheel lever 23 is pressed against the anchor wire 4. When the wire feed lever 10 is pivoted in the direction of the stuffing tool 3, the wire feed lever is moved against the compression spring 5 by way of the anchor wire 4 advanced in the direction of the stuffing tool 2. During the return movement of the respective wire driver 6 in the opposite direction, the freewheel lever 23, which can also be referred to as a freewheel wedge 23, prevents the armature wire 4 from being pulled back again from a wire guide 26 extending between the stuffing tool 2 and the wire driver 6.
    Each tamping machine 1 shown also includes an adjusting device 27. The adjusting device 27 is designed to change the transport step width of the wire carrier 6 and in particular to change the relative position of the adjusting link 8 on its link guide 9. The adjusting device 27 includes both an automatic and a manual actuator 28. The automatic actuator 28 can be designed as a drive motor. A screw knurl can be used as a manual actuator 28, for example. Both the drive motor and the screw knurl are connected to the spindle 12 serving as a link guide 9. The transport step width can be changed at least indirectly by rotating the spindle 12.
    Each tamping machine 1 shown also has an input interface 29 for inputting a transport step width or an anchor length to be set, and an instruction memory 30, which can also be designed or designated as a program memory.
    In the instruction memory 30, certain transport steps, swivel angle ranges and / or relative positions of the setting link 8 as well as certain armature lengths of individual brushes and / or
    BE2018 / 5536
    Broom types can be assigned, which can be manufactured with the help of the tamping machine 1. Furthermore, entire production programs can also be assigned to individual brush or broom types in the instruction memory 30. The data stored in the instruction memory 30 can, if necessary, be displayed on the display device 11 of the tamping machine 1.
    Each tamping machine 1 shown also has a control unit 31 which is coupled to the respective actuator 28 and to the sensor 7. The control unit 31 is set up to read out data stored in the instruction memory 30 for the automatic setting of the transport step and to use it for the automatic adaptation of the transport step width and thus also the anchor length.
    In the tamping machine 1 shown in FIG. 2, the control unit 31 is arranged adjacent to the sensor 7, which is designed as a rotary encoder, and is connected to the latter via a signal connection 41 in the form of a signal line. The control unit 31 of the tamping machine 1 from FIG. 2 can thus function as an evaluation unit or control unit with which new operating parameters or values for the actuator 28 of the setting link 8 can be determined and predefined as a function of a transport step width determined with the sensor 7. In this way, control can also be implemented with the control unit 31.
    Each tamping machine 1 shown also has a cutting device 32. With the aid of the cutting device 32, individual wire anchors can be separated from the supplied anchor wire 4 in the desired length. An anchor length corresponding to the transport step width of the feed device 3 is set. So the longer the transport step is,
    BE2018 / 5536 with which the feed device 3 feeds the anchor wire 4 in the direction of the tamping tool 2 and also in the direction of the cutting device 32, the greater the length of the cut or sheared wire anchors.
    1 and 2, each tamping machine 1 also has a bundle compartment device 33 and a material box 34 with three individual material channels. A supply of three types of different loose bristle filaments is arranged in the material box 34. With the help of the bundle compartment device designed as a circular arc divider and a bundle removal notch on the circular arc divider, individual bristle bundles can be removed from the stock of loose bristle filaments of the material box 34 and fed to the tamping tool 2 by an alternating pivoting movement (double arrow PF1).
    After the divided bristle bundle has been fed to the tamping tool 2 with the bundle compartment device 33, the bristle bundle can be plugged into a receiving opening 37 of a bristle carrier 5 and anchored there with the aid of a pusher tongue 36 alternately moving in a tappet channel 35 of the tamping tool 2 together with a wire anchor provided. The movement of the ram tongue 36 is indicated by the double arrow PF2. The bristle carrier 5 is clamped on a holder 38 of the tamping machine for this purpose.
    The double arrow PF3 illustrates the alternating movement of the wire feed drive 22, while the arrow PF4 represents a movement of the setting link 8 on the link guide 9. The double arrow PF5 shows that the material box 34 can also be pivoted. This in order to move the different material channels with their removal openings into a removal position on the compartment device 33.
