Abstract
Description
[0001] The invention relates to a method for separating bristle bundles from a supply of loose bristle filaments, wherein a bundle divider with a dividing notch is moved past the supply of loose bristle filaments in a dividing movement, whereby a bristle bundle is separated from the supply and the bristle bundle enters the dividing notch.
[0002] Furthermore, the invention also relates to a dividing device for separating bristle bundles from a supply of loose bristle filaments. The device can be configured to carry out the aforementioned method. A brush stuffing machine with such a dividing device is also proposed.
[0003] DE 31 51 730 A1 discloses a brush manufacturing machine which has a multi-stage magazine for feeding bristles from a bristle supply to a tuft divider belonging to a stuffing tool. Bristles can be selectively or alternately removed from the feed channels of this magazine in tufts, and the multi-stage magazine is pivotable or displaceable relative to the divider. The brush manufacturing machine is characterized in that the multi-stage magazine has a pivoting section at its discharge end, the pivoting movement of which is coordinated with the alternating access of the tuft divider to the ends of the feed channels.
[0004] DE 199 39 333 A1 discloses a brush manufacturing machine with a multi-magazine which, for feeding bristle bundles from different bristle stores to a bundle divider having at least one dividing notch for a stuffing tool, has several feed channels with discharge ends limited by side boundaries, wherein at least one retaining element which can be positioned in a discharge position and a closing position is arranged at the discharge ends of the feed channels, and wherein the dividing notch(es) of the bundle divider can be positioned in a transfer position on the stuffing tool for transferring a bristle bundle held therein.The brush manufacturing machine is characterized in that the bundle divider is formed by a circulating, belt-like conveying element guided by deflecting elements, which has the divider notch(es) on one of its longitudinal sides, that the conveying element, for receiving at least one bristle bundle from at least one of the feed channels, can be guided past the discharge ends of the feed channels with its divider notch(es) facing them and can be positioned at the tamping tool for transfer with the filled divider notch, and that removable side guides are provided at the discharge ends of the feed channels to retain the bristles located in the divider notch(es), and a fixed side guide leading to the tamping tool is provided in the conveying direction following the discharge ends.
[0005] Bristle bundles are needed for the production of brushes, such as toothbrushes. These bundles can be separated from a supply of loose bristle filaments using a bundle divider. The bundle divider is moved along the supply of loose bristle filaments in a dividing motion. A dividing notch formed on the bundle divider moves through a section of the supply of loose bristle filaments, causing bristle filaments to enter the notch and form bristle bundles.
[0006] Using the bundle divider, the separated bristle bundle can then be fed to a tamping tool of a brush tamping machine. The tamping tool can then remove the bristle bundle from the divider notch and tamp it into a receiving hole of a waiting brush body.
[0007] When separating bristle bundles from a supply of loose bristle filaments, the aim is to produce bundles with as consistent a number of filaments as possible. The number of filaments contained in a bristle bundle is determined by the shape and size of the separation notch and can influence the bundle's performance characteristics. Therefore, the separation notch should be filled as completely as possible with filaments during each separation process. This ensures the production of bristle bundles containing a consistent or only slightly varying number of filaments.
[0008] The object of the invention is therefore to provide a method for separating bristle bundles, a separating device for separating bristle bundles and a brush stuffing machine of the type mentioned above, which promote a reliable and constant filling of the separating notch with bristle filaments.
[0009] To solve the problem, a method for separating bristle bundles from a supply of loose bristle filaments is proposed, which includes the means and features of the independent claim directed to such a method. In particular, a method for separating bristle bundles from a supply of loose bristle filaments is proposed, wherein a bundle separator with a separating notch moves past the supply of loose bristle filaments in a separating motion, separating a bristle bundle from the supply and placing it into the separating notch. During the separation motion, the separating notch changes its direction of movement at least twice, preferably at least three times, within a separation area of the supply. Changing the direction of movement of the separating notch during the separation of bristle bundles from the supply of loose bristle filaments within the separation area facilitates the filling of the separating notch.When separating bristle bundles from a supply of loose bristle filaments, a rear edge, located in the direction of movement of the separating notch and defining the notch's boundaries, plays a crucial role. Bristle filaments facing the separating notch come into contact with this rear edge during the separation movement and are guided into the notch by it. The filling of the notch thus occurs, at least in part, via this rear edge. By changing the direction of movement of the separating notch during the separation movement, the notch can be filled multiple times from different directions. This promotes a distribution of the bristle filaments within the notch.By changing its direction of movement at least twice, preferably at least three times, when performing the division movement in a division area on the stock according to the invention, the division notch can be filled with bristle filaments particularly reliably and as completely as possible.
[0010] An even number of changes in direction of the compartment notch when executing the compartment movement in the compartment area makes it possible to move the compartment notch into the compartment area on one side of the compartment area and to remove it from the compartment area on another side of the compartment area.
[0011] In the case of an odd number of changes of direction, the compartment notch can be removed from the compartment area via the side over which the compartment notch was previously moved into the compartment area.
[0012] In one embodiment of the method, the sectioning notch can pass through at least two, preferably at least three, reversal points during the sectioning movement. These reversal points are arranged in the sectioning area on the supply of loose bristle filaments. The reversal points can, for example, be located at different positions within the sectioning area. The sectioning movement, in which the sectioning notch is moved through the sectioning area on the supply of loose bristle filaments, can have a sinusoidal or sinusoidal profile.
[0013] If the compartment notch passes through at least two, preferably at least three, reversal points during the compartment movement, it is possible to make the compartment area containing the supply of loose bristle filaments smaller without reducing the dwell time of the compartment notch within the compartment area. The dwell time of the compartment notch during the compartment movement can also influence the filling of the compartment notch with bristle filaments. Overall, the method thus enables a reduction in the dimensions of the compartment area and consequently a reduction in the space required for a bristle magazine in which the bristle filaments from the supply of loose bristle filaments can be stored.
[0014] In this way, it is possible to provide a dividing device with a more compact bristle magazine. This allows for the provision of a dividing device and a brush filling machine that require less overall space, or whose bristle magazines, while occupying the same space, can have a greater number of material channels for storing, for example, different types of bristle filaments.
[0015] In one embodiment of the method, the dividing notch, during the dividing movement, passes at least two rear reversal points facing away from a tamping tool. These rear reversal points can be arranged at different positions on the stock within the dividing area. The at least two rear reversal points allow bristle filaments to be picked up at different positions within the dividing area. This can also facilitate the filling of the dividing notch with bristle filaments.
[0016] In one embodiment of the method, the sectioning movement of the sectioning notch can be generated by superimposing at least two movements. These at least two movements can, for example, be sinusoidal and / or have different amplitudes. It is also possible to compose the sectioning movement from at least two successively executed movements. Here, too, the movements can, for example, be sinusoidal and / or have different amplitudes.
[0017] A first movement of at least two movements can be a main movement of the dividing notch, by which the dividing notch is moved between a stuffing tool and the supply of loose bristle filaments.
[0018] The second movement of the at least two movements can be an additional movement of the compartment notch, which the compartment notch, in particular the bundle divider on which the compartment notch is arranged, performs within the compartment area on the supply.
[0019] The main movement can be caused by a drive motor, in particular by an output shaft of the drive motor, a partitioning device, and / or a brush stuffing machine. The auxiliary movement can be caused by an actuator, for example, a piezoelectric element. The actuator can, for example, be arranged in the power flow between the bundle partition, on which the partitioning notch is formed, and a drive motor for the bundle partition.
[0020] In one embodiment of the method and also in the compartment device described in more detail below, the actuator can be configured to adjust the length of a drive rod, via which the bundle compartment can be connected at least indirectly to the drive motor.
[0021] In this way, the additional movement of the compartment notch can be caused by a length adjustment of this drive rod effected by the actuator and, if necessary, superimposed on the main movement of the bundle divider and its compartment notch.
[0022] In one embodiment of the method, the frequency and / or amplitude of the auxiliary movement and / or the main movement are preset by a preferably programmable control unit, which can be configured to control the actuator and / or the drive motor. If necessary, the frequency and / or amplitude of the auxiliary movement and / or the main movement can also be changed by the control unit. This allows for easy adaptation of the method to a modified production program.
[0023] Using a control unit, reversal points can be specified in any number and / or position in the compartment area of the supply of loose bristle filaments, thereby allowing the compartmentation of bristle bundles from the supply of loose bristle filaments to be adjusted as needed.
[0024] To solve the problem, a dividing device for separating bristle bundles from a supply of loose bristle filaments is also proposed, which has the means and features of the independent claim directed to such a dividing device. According to the invention, the dividing device comprises a bundle divider with at least one dividing notch, a bristle magazine for a supply of loose bristle filaments, and a drive device configured to move the bundle divider with the at least one dividing notch in a dividing motion through a dividing area of the supply of loose bristle filaments such that the dividing notch changes its direction of movement in the dividing area at least twice, preferably at least three times. In this way, a dividing device is created that can be used to carry out the previously described method and thus for the particularly reliable dividing of bristle bundles from the supply of loose bristle filaments.The compartment device can in particular be equipped by the drive device for carrying out the method according to one of the claims directed to such a method.
[0025] The drive device can comprise a drive motor and a gearbox. The drive motor can be connected to the bundle divider via the gearbox. The gearbox can be configured to convert the movement of an output shaft of the drive motor into a movement of the bundle divider and its dividing notch. The drive motor of the drive device for the dividing device can be a drive motor of a brush stuffing machine equipped with the dividing device.
[0026] In one embodiment of the partitioning device, the gearbox is provided with a control cam. The control cam can define the partitioning movement of the bundle partition and thus the partitioning movement of the partition notch, and can be driven by the drive motor of the drive device. The control cam can be arranged on or formed on a cam carrier, for example, on a so-called double eccentric, which can be designed as a cam disk. The double eccentric can be part of the gearbox and be driven, at least indirectly, by the drive motor of the drive device.
[0027] The control cam can be designed such that a rotation of the control cam about an axis of rotation is transmitted to the bundle divider via a mechanical connection, which may include a drive rod. The control cam can be designed such that, during the execution of the division movement, the division notch in the division area of the supply of loose bristle filaments changes its direction of movement at least twice, preferably at least three times.
[0028] The mechanical connection can include a tap element, for example, a roller. The tap element can be connected to the bundle divider via the previously mentioned drive rod. Movement of the control cam can then be transmitted to the bundle divider via the tap element and the drive rod.
[0029] In one embodiment of the compartment device, the drive device's transmission includes a connecting rod drive with which at least part of the compartment movement, in particular the aforementioned main movement, can be caused by the compartment notch.
[0030] The gearbox can include an actuator, for example a piezoelectric element, which is configured to cause an additional movement of the dividing notch, such as the previously mentioned one. In this embodiment of the dividing device, this actuator can then effect at least one of the at least two, preferably three, changes in the direction of movement of the dividing notch in the dividing area of the supply of loose bristle filaments.
[0031] The actuator can be configured to adjust the length of a drive rod of the gearbox connected to the bundle divider. The actuator can be positioned in the power flow between the drive motor and the bundle divider. The actuator can be combined with either a cam or a connecting rod drive.
[0032] The drive device can include a control unit, preferably programmable, which is configured to control the drive motor and / or the actuator. The control unit can be programmed and / or configured such that the partitioning notch changes its direction of movement at least twice, preferably at least three times, during the partitioning movement in the partitioning area. The partitioning device can thus be configured by the control unit to carry out the method for partitioning bristle bundles according to one of the claims directed to such a method.
[0033] The control unit can also, for example, adjust the frequency and / or amplitude of the aforementioned auxiliary movement and / or main movement of the compartment notch. Preferably, this control unit has a data interface for connection to a data storage device, in particular a cloud-based data storage device. Furthermore, the control unit can be programmable. For example, the number and / or position of reversal points of the compartment movement in the compartment area on the supply of loose bristle filaments can be specified.
[0034] Control programs can be accessed via the data interface, thus influencing the movement of the divider notch. Particularly when the divider is used in a production line, this interface allows control programs and / or operating parameters to be stored in the data memory and made available to other dividers. This enables efficient control of a production line comprising multiple dividers, which may even be operated at different locations.
[0035] In one embodiment of the partitioning device, the bundle divider is designed as a circular arc divider and can be pivoted about a pivot axis to perform the partitioning movement. In another embodiment of the partitioning device, the bundle divider is designed as a partition slide. The partition slide can be moved in an alternating linear motion to perform the partitioning movement. In a further embodiment of the partitioning device, the bundle divider is designed as a partition disk. The partition disk can be pivoted or rotated about a pivot axis to perform the partitioning movement. In particular, in a bundle divider designed as a partition disk, the at least one partitioning notch can perform an even number of changes of movement in the partitioning area at the supply of loose bristle filaments when the partitioning movement is performed.
[0036] To solve the problem, a brush stuffing machine with a partitioning device according to one of the claims directed to such a partitioning device is also proposed, which further comprises a stuffing device with a stuffing tool which is configured to stuff bristle bundles provided by the partitioning device into a bristle carrier of a brush.
[0037] The tamping device and the compartmentalizing device can be driven by a common drive motor. This drive motor can then also be referred to as the drive motor for the compartmentalizing device or the drive motor for the tamping device.
[0038] The output shaft of the drive motor and the tamping tool can be connected via an eccentric. The eccentric converts the rotation of the output shaft into an alternating motion of the tamping tool. The drive motor's output shaft can serve as the main shaft of the brush tamping machine, its motion being transmitted via the eccentric to the tamping tool and, via the previously mentioned gearbox of the partitioning device, to the bundle partition and the partitioning notch.
[0039] The invention is described in more detail below with reference to exemplary embodiments, but is not limited to these. Further exemplary embodiments result from combining the features of one or more claims with one another and / or from combining one or more features of the exemplary embodiments. The following are shown: Fig. 1 a perspective view of a brush stuffing machine with a stuffing device having a stuffing tool and with a dividing device whose bundle divider has a dividing notch and is connected via a connecting rod drive to a drive motor which also serves as a drive for the stuffing tool, Fig. 2.

A representation illustrating the compartment movement of a bundle divider designed as a compartment slider and its compartment notch in the compartment area on a bristle magazine with a supply of loose bristle filaments, wherein the representations in column A show a compartment movement of the compartment notch without multiple changes of direction of the compartment notch and the representations in column B show a compartment movement of the compartment notch with three changes of direction of the compartment notch in the compartment area. Fig. 10 a diagram illustrating a compartment movement of a compartment notch with only one change of direction in the compartment area and in which a swivel angle of the bundle compartment (Y-axis) is plotted against a rotation angle of an output shaft of the drive motor (X-axis) of the brush stuffing machines shown in the previous figures, as well as Fig. 11 a diagram illustrating the compartmental movement of a with three changes of direction in the compartmental area on a supply of loose bristle filaments.
[0040] In the following description of figures, elements of the described objects that correspond in function are given corresponding reference symbols even if their design or shape differs.
[0041] The Fig. Figures 1-8 show different brush stuffing machines, each designated as a whole by 1. Each of the brush stuffing machines 1 shown has a dividing device 2 and a stuffing device 3 with a stuffing tool 4, which is designed to stuff bristle bundles 5 provided by the dividing device 2 into a bristle carrier 6 clamped on the brush stuffing machine 1.
[0042] The tamping tool 4 and the dividing device 2 are connected to a common drive motor 7 of the brush tamping machine 1. Thus, the tamping tool 4 and the dividing device 2 can be driven by the common drive motor 7. The drive motor 7 can therefore be referred to as the drive motor of the dividing device 2 and also as the drive motor of the tamping device 3 and the tamping tool 4.
[0043] In all brush stuffing machines 1 shown in the figures, an output shaft 8 of the drive motor 7 is connected to the respective stuffing tool 4 of the stuffing device 3 via an eccentric 9.
[0044] The dividing device 2 serves to divide bristle bundles 5 from a supply 10 of loose bristle filaments 11. The supply 10 of loose bristle filaments 11 is arranged in a bristle magazine 12 of the respective dividing device 2. The bristle magazine 12 can also be referred to as a material box and has three material channels 25, in each of which one type of bristle filament 11 can be arranged.
[0045] Each partitioning device 2 comprises a bundle partition 13 with a partition notch 14, a bristle magazine 12 for the supply 10 of loose bristle filaments 11, and a drive device 15. The drive device 15 is configured to move the bundle partition 13 with the partition notch 14 in a partitioning motion through a partitioning area 16 past the supply 10 of loose bristle filaments 11 such that the partition notch 14 changes its direction of movement at least twice, preferably at least three times, in the partitioning area 16. This facilitates reliable filling of the partition notch 4 with loose bristle filaments 11 for partitioning bristle bundles 5 from the supply 10.
[0046] The in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. The bundle dividers 13 shown in section 8 are circular arc dividers that can be pivoted about a pivot axis. The ones shown in Fig. The bundle compartments 13 shown in 9 are linearly movable compartment sliders.
[0047] The drive device 15 of the compartment device 2 has as its drive motor the drive motor 7 of the brush stuffing machine 1 and a gearbox 17, via which the drive motor 7 is connected to the bundle compartment 13 of the compartment device 2.
[0048] The gearbox 17 is designed to convert the movement of the output shaft 8 of the drive motor 7 into the aforementioned compartment movement. The [unclear text] Fig. The compartment devices 2 shown in Figures 1-8 differ in particular in the design of their respective gearboxes 17.
[0049] The in the Fig. The compartment devices 2 shown in Figures 5-8 feature a gearbox 17 with a control cam 18 formed on a double eccentric 19. The double eccentric 19 serves as the cam carrier. The control cam 18 determines the compartment movement of the bundle divider 13 and the compartment notch 14, as well as the previously mentioned changes in direction of the compartment notch 14 within the compartment area. The drive motor 7 is connected to the double eccentric 19 and thus also to the control cam 18. The bundle divider 13 is connected to a drive rod 30. Via a pull-off element 31, here a roller, and a transmission lever 32, the movement of the control cam 18 can be transmitted to the drive rod 30 and from there to the bundle divider 13.
[0050] The in the Fig. The compartment devices 2 shown in Figures 1-4 have a transmission 17, each comprising a connecting rod drive 20, with which at least part of the compartment movement, in particular the previously mentioned main movement of the bundle compartment 13 and its compartment notch 14, can be caused.
[0051] In the Fig. In the compartment device 2 shown in Figures 2-4 and 6-8, the respective gearbox 17 also has an actuator 21, namely a piezoelectric element, which is designed and intended to perform an additional movement of the compartment notch 14. With the aid of the actuators 21, it can be caused that the compartment notch 14 on the bundle divider 13 in the compartment area 16 changes its direction of movement when the compartment movement is executed.
[0052] The actuators 21 shown in the figures are each configured to adjust the length of a drive rod 30 of the gearbox 17 connected to the respective bundle divider 13. The actuators 21 are arranged in the power flow between the drive motor 7 and the respective bundle divider 13.
[0053] The in Fig. 1 and Fig. Each of the five brush-filling machines 1 shown has a control unit 21, which is configured to control the respective drive motor 7. The drive device 15 of the compartment devices 2 according to the Fig. 2-4 and 6-8 are equipped with a control unit 22, which is set up to control the drive motor 7 and the respective actuator 21.
[0054] Each of the control units 22 shown in the figures has a data interface 23 for connecting to a data storage device 24, in particular a cloud-based data storage device.
[0055] Via the data interfaces 23, control programs and / or operating parameters for the operation of the dividing device 2, the tamping device 3, and the brush tamping machine 1 as a whole can be retrieved from the data memory 24 or stored in it for other brush tamping machines 1, dividing devices 2, or tamping devices 3 and their control units 22. The data interface 23 of the respective control unit 22 is thus designed as a bidirectional data interface 23.
[0056] Each partitioning device 2 shown in the figures is set up to carry out the following method for partitioning bristle bundles 5 from a supply 10 of loose bristle filaments 11.
[0057] In this process, a bundle divider 13 with its divider notch 14 is moved past the supply 10 of loose bristle filaments 11 in a divider movement. A bristle bundle 5 is thereby separated from the supply 10, causing the bristle bundle 5, which consists of a number of loose bristle filaments 11, to enter the divider notch 14.
[0058] When the compartment movement is carried out, the compartment notch 14 is moved in the compartment area 16 on the supply 10 in such a way that it changes its direction of movement at least twice, preferably at least three times, in the compartment area 16.
[0059] Fig. Figure 11 shows a diagram in which the angular position of the bundle divider 13, and thus the position of the divider notch 14, relative to the supply 10 of loose bristle filaments 11, is plotted against a rotation angle of the output shaft 8 of the drive motor 7. A comparison with the diagram from Fig. 10 makes it clear that the compartment notch 14 is executed according to the curve. Fig. 11 in compartment area 16 at storage 10 changes its direction of movement three times. A comparable compartment movement is also illustrated in the diagrams in column B. Fig. 9.
[0060] Based on the curve from Fig. The reversal points 26, 27, and 28 of the compartment notch 14 in compartment area 16 at the supply 10 can also be identified. The two maxima of curve 11 illustrate rear reversal points 26 and 28 of the compartment notch 14 in compartment area 16, which are already reached at an angular position of the bundle divider 13 of slightly less than 75°. The minimum of the curve between reversal points 26 and 28 represents a front reversal point 27, which is passed by the compartment notch 14 during the execution of the compartment movement.
[0061] In comparison, this shows Fig. 10, that according to the curve from Fig. 10. The compartment movement of the bundle divider 13 leads the compartment notch 14 to only one rear reversal point, which, however, is only reached when the bundle divider 13 has already been pivoted by 80°.
[0062] Fig. Figure 11 shows that the inventive method and the associated partitioning movement of the bundle partitioner 13 enable a reduction in the size of the partitioning area 16 at the supply 10 of loose bristle filaments 11, in which the partitioning of bristle bundles 5 takes place, without reducing the duration that the partitioning notch 14 remains in the partitioning area 16. Thus, more compact bristle magazines 12 or bristle magazines 12 with a larger number of correspondingly narrower material channels 25 can be used.
[0063] The compartment notches 14 can pass at least two, three, or possibly even more reversal points 26, 27, and 28 during the execution of the compartment movement in all compartment devices 2 shown in the figures. According to the illustrations in column B of the Fig. 9 and also according to Fig. During the process carried out on the partitioning devices 2, the partitioning notches 14 pass a total of 3 reversal points 26, 27 and 28, which are each located in the partitioning area 16 at the supply 10 of loose bristle filaments 11 and may be arranged at different positions. The partitioning movement that the partitioning notch 14 then performs has a sinusoidal shape and can be understood as the superposition of two sinusoidal movements.
[0064] Fig. Figure 11 shows that the compartment notch 14, during the compartment movement, passes two rear reversal points 26 and 28, each facing away from the tamping tool 4 of the respective tamping device 3, which can be arranged at different positions in the compartment area 16 on the stock 10. The in Fig. The illustrated compartment movement of the compartment notch 14 can be generated by superimposing at least two movements, each of which can be sinusoidal and / or have different amplitudes. It is also possible to compose the compartment movement of the compartment notch 14 from at least two successively executed movements, for example, sinusoidal and / or having different amplitudes.
[0065] One of the at least two movements can be a main movement of the partitioning notch 14, by which the partitioning notch 14 is moved between the previously mentioned stuffing tool 4 of the respective brush stuffing machine 1 and the supply 10 of loose bristle filaments 11, which is arranged in the bristle magazine 12 of the respective partitioning device 2. By means of the main movement, the partitioning notch 14 can be moved into the partitioning area 16 and also removed from the partitioning area 16.
[0066] A second movement, among at least two movements, can be an additional movement of the compartment notch 14, which the compartment notch 14 performs within the compartment area 16 at the supply 10 and thus at the bristle magazine 12. The main movement of the compartment notch 14 can be caused by the previously mentioned drive motor 7 and, in particular, by a rotation of its output shaft 8.
[0067] The additional movement of the compartment notch 14 can be caused by the previously mentioned actuator 21 or, if necessary, by the drive motor 7.
[0068] The frequency and / or amplitude of the auxiliary movement and / or the main movement can be specified by a preferably programmable control unit 22, such as those provided by the brush filling machines 1 shown in the figures for the partitioning devices 2, the filling devices 3, and the control of the drive motor 7. Via the previously mentioned data interface 23, the brush filling machines 1 shown in the figures are configured to retrieve control programs and / or operating and production parameters for controlling the individual functional units of the brush filling machine 1, i.e., the partitioning device 2 and the filling device 3. Control programs, operating and production parameters for other brush filling machines 1 and their partitioning devices 2 and filling tools 3 operated in a common production network can also be stored in the data memory 24 via the data interfaces 23.
[0069] The representation from Fig. Figure 9 shows a bundle divider 13, which is designed as a linearly movable compartment slide and has a compartment notch 14. The in Fig. The arrows assigned to reference symbol 13 of the bundle divider illustrate the direction of movement of the bundle divider 13 in the individual phases of the compartment movement, which are shown in lines I to VII of the Fig. 9 are shown.
[0070] The representations from column A in Fig. Figure 9 illustrates a compartment movement in which the bundle compartment 13 and its compartment notch 14 change their direction of movement only once in the compartment area 16.
[0071] According to column A, row I, the compartment notch 14 enters the compartment area 16 at the bristle magazine 12 with the supply 10 of loose bristle filaments 11. According to column A, row II, the movement of the bundle divider 13, and thus the movement of the compartment notch 14, continues through the compartment area 16 until the compartment notch 14, via the intermediate position illustrated in column A, row III, reaches its only rear reversal point, shown in column A, row IV.
[0072] Starting from the position in column A, row IV, the compartment notch 14 is then moved again via the positions shown in column A, rows VI and VII from the compartment area 16 to the supply 10.
[0073] The representations from column B in Fig. Figure 9 shows a compartment movement of the compartment notch 14 in which the compartment notch 14 changes its direction of movement three times in the compartment area 16.

Column B, row II shows that loose bristle filaments 11 enter the compartment notch 14 via a rear edge 29 of the compartment notch 14, which is located in the direction of movement of the compartment notch 14 through the compartment area 16. If the direction of movement of the compartment notch 14 is reversed, the compartment notch 14 is filled via a second edge 33 of the compartment notch 14, which is opposite the first edge 29.
[0075] According to column B, row III, the compartment notch 14 has reached its first, rear reversal point 26. Starting from this first rear reversal point 26, the compartment movement of the compartment notch 14 continues in the opposite direction, whereby the compartment notch 14 reaches the position shown in column B, row IV, in which the compartment notch 14 has reached its front reversal point 27 in the compartment area 16.
[0076] From this front reversal point 27, the compartment notch 14 is then moved to the second, rear reversal point 28. The compartment notch 14 has then reached the rear reversal point 28 in the representation according to column B, row V.
[0077] From this rear reversal point 28, the compartment notch 14 is then extended via the in Fig. 9, column B, rows VI and VII show the positions from compartment area 16 on the supply 10 of loose bristle filaments 11.
[0078] In column B, row III of Fig. 9 is shown as the first and therefore also the rearmost reversal point 26 of the two rear reversal points 26 and 28, which the compartment notch 14 passes when carrying out the procedure.
[0079] In comparison, this shows Fig. 9, column A, line IV, that the compartment notch 14 was moved significantly further in the rear reversal point shown there.
[0080] A comparison of the representation from column A, row III of the Fig. 9 with the representation from column B, row IV of the Fig. Paragraph 9 thus makes it clear that the proposed method, in which the compartment notch 14 changes its direction of movement in the compartment area 16 at least twice, preferably at least three times, enables a reduction in the width of the compartment area 16.
