DEVICE FOR COMPACTING BRISTLE BUNDLES, BRISTLE PRODUCT MANUFACTURING MACHINE AND METHOD FOR COMPACTING BRISTLE BUNDLES

Description

[0001] The invention relates to a device for compacting bristle bundles for the production of bristle goods, a bristle goods manufacturing machine with such a device and a method for compacting bristle bundles.

[0002] From the publication DE 100 05 249 A1, a brush manufacturing machine with a multiple feed for strand-shaped bristle material, which has a feed device for the bristle strands, as well as with a cutting device for bristle bundles and a feeding device for feeding the bristle bundles to a device for connecting the bristle bundles with a brush body is known.The brush manufacturing machine is characterized in that the feed device is designed for an independent, controllable feed of the individual bristle strands, that the feeding device has a conveying means that can be positioned incrementally with holes for bristle strands or bristle bundles, that feeds for the bristle strands are provided for each step position of one of the holes in the conveying means, and that one or more shearing devices cooperating with the conveying means for cutting the bristle strands to length are arranged at the bristle strand feeds.

[0003] US 2005 116 528 A1 discloses a device for manufacturing brushes, which essentially consists of a stuffing tool and at least one feed channel and is characterized in that at least one rounding means is provided between the feed channel and the stuffing tool.

[0004] DE 100 62 398 A1 discloses a method for forming a bristle bundle, in which a receiving device is passed by at least one filament container, in which bristle filaments contained in the filament container are picked up and fed to a removal device, wherein the receiving device is rotated around its circumference.

[0005] DE 10 2016 004 927 A1 discloses a bundle removal device for a brush manufacturing machine, comprising a bundle remover which has a bundle removal notch on its front side facing a bristle supply in its operating position. The bundle remover is movable past the bristle supply with the bundle removal notch between a bundle intake position and a bundle discharge position to remove a bristle bundle from the bristle supply and to discharge a collected bristle bundle to the brush manufacturing machine. The bundle removal device has at least one movable pressure piece which can be inserted into the bundle removal notch to change the cross-section of the bundle removal notch.The pressure piece is displaceable in the bundle removal notch transversely to the longitudinal direction of the bundle removal notch between a first edge running transversely to the longitudinal direction of the bundle removal notch and a second edge of the bundle removal notch opposite the first edge.

[0006] For the manufacture of bristle products, for example brushes such as toothbrushes, bristle filaments are extracted from a supply of loose bristle filaments in the form of bristle bundles using a supply device, for example a bundle divider.

[0007] The delivery devices used in this process can have bundle notches that guide them past the supply of loose bristle filaments. A specific number of bristle filaments then enter the bundle notches. The bristle filaments arranged in a bundle notch together form a bristle bundle.

[0008] The bristle bundles in the bundle notches are still unshaped and uncompacted. The filament density of the bristle bundles in the notches is still relatively low, and the bristle bundles do not yet have the shape they will later have in the finished bristle product. For use in the finished bristle product, it is desirable to increase the filament density of the bristle bundles and, if necessary, to shape the bristle filaments accordingly.

[0009] Compacting and, if necessary, shaping bristle bundles involves a certain amount of effort. In practice, for compaction, the bristle bundles are pushed through narrowing channels in so-called funnel plates. The precise manufacturing of these funnel plates is relatively expensive, but crucial for achieving the desired degree of compaction. Depending on the required degree of compaction, the process may be carried out in several stages, requiring a corresponding number of funnel plates connected in series.

[0010] The object of the invention is to provide a device for compacting bristle bundles, a bristle goods manufacturing machine and a method for compacting bristle bundles, which allow efficient and economical compaction of bristle bundles for the production of bristle goods.

[0011] To solve this problem, a device for compacting bristle bundles with the features of the independent claim directed to such a device is first proposed.To solve the problem, a device for compacting bristle bundles is proposed in particular, wherein the device has at least one supply means with bundle notches and a number of compaction receptacles for bristle bundles that at least corresponds to the number of bundle notches, and for each of its compaction receptacles, a compaction means, characterized in that the compaction receptacles are formed in at least one extraction plate of the device and are configured for extracting bristle bundles from the bundle notches of the supply means, and the compaction means are configured for compacting bristle bundles positioned in the compaction receptacles, and that the at least one extraction plate and / or at least one compaction means has a receiving space, namely a slot, in which the supply means and / or a counterpart is positioned during the extraction and / or compaction of bristle bundles.

[0012] The dispensing device allows bristle bundles to be separated from a supply of loose bristle filaments and presented in an uncompacted form. Using the compaction receptacles of the device, the uncompacted bristle bundles can first be removed from the bundle notches of the dispensing device in a single operation and then compacted to a desired degree of compaction using the compaction elements. This degree of compaction is determined by the bristle bundles' intended density in a subsequent processing step and / or in the finished bristle products. This enables particularly efficient production of bristle products. According to the invention, the compaction receptacles are formed in at least one dispensing plate of the device. In one embodiment of the device, the compaction receptacles are formed in two or more dispensing plates.

[0013] The compaction elements can be moved transversely to the longitudinal direction of the compaction supports into a compaction position at or within the compaction supports by a relative movement of the compaction supports to the compaction elements. This relative movement of the compaction supports to the compaction elements can be transverse, particularly perpendicular, to an orientation of the bristle bundles and their longitudinal axes in the bundle notches, as determined by the orientation of the bundle notches of the delivery device.

[0014] The compaction receptacles can each have an insertion opening into which bristle bundles and / or compaction material can be inserted. The insertion openings can be oriented transversely or perpendicularly to a longitudinal axis of the respective compaction receptacle and / or transversely or perpendicularly to a longitudinal axis of bristle bundles arranged within the compaction receptacles. This allows the bristle bundles to be first extracted from the bundle notches of the delivery material in a relative movement transversely or perpendicular to their longitudinal axis and then compacted in the same direction.

[0015] Compaction can be achieved, for example, by the compaction agents entering the compaction receptacles through the introduction opening of the compaction receptacles in a compaction movement oriented transversely or perpendicularly to the orientation of the longitudinal axes of the bristle bundles arranged in the compaction receptacles, where they then compact the bristle bundles located therein.

[0016] The insertion openings of the compaction devices may be limited by insertion chamfers. These chamfers allow for the gentle introduction of the compaction material into the device's compaction devices and can help prevent damage to the compaction material and / or the compaction devices.

[0017] It should be noted here that the compaction attachments can either be moved themselves to reach a compaction position within the compaction attachments, or the compaction attachments can be moved relative to the compaction material to perform the previously described relative movements of the compaction attachments to the compaction material. It is also possible to move both the compaction attachments and the compaction material to perform the relative movements for compaction.

[0018] To prevent bristle filaments from escaping a compaction chamber during compaction, it can be advantageous for at least one compaction element to have a sharp-edged transition between its flanks and its end face facing the compaction chamber to which the compaction element is assigned. This sharp-edged transition allows the compaction element to be designed to fit precisely and closely against the inner wall of the compaction chamber. The sharp-edged transition between the flanks and the end face of the compaction element prevents bristle filaments arranged within the compaction chamber from escaping past the compaction element during the previously described relative movement of the bristle bundles during compaction.

[0019] At least one compacting agent can be smoothed and / or hardened on at least one flank adjacent to its end face facing a compaction receptacle. The flank can, for example, have a surface roughness of Ra 0.01–1.6, preferably Ra 0.01–0.04, and / or a hardness, in particular a surface layer hardness with a depth of 1.2–1.8 Rht, of 55–63 HRC, preferably 60–63 HRC.

[0020] The compaction elements can each have a cross-section whose measurable width is smaller than the width of a cross-section of the compaction receptacle arranged in the same cross-sectional plane. In this way, the compaction elements can be inserted into the compaction receptacles through the insertion openings for compacting bristle bundles.

[0021] At least one compaction element of the device can have a subsize of 0 µm to 50 µm, in particular a subsize of 0 µm to 20 µm, measurable in a lateral direction of the compaction receptacle associated with it, relative to a clear width of an insertion opening of the compaction receptacle measurable in the same lateral direction.

[0022] The previously specified tolerance ranges for undersize can depend, for example, on the thickness of the bristle filaments of the bristle bundles to be compacted. For bristle filaments with a thickness of 3 mil, the tolerance range can be, for example, 0 µm to 20 µm. For larger filament thicknesses, such as bristle filaments with a thickness of 8 mil, a comparatively larger tolerance range may suffice, for example, a tolerance range of 0 µm to 50 µm for the undersize described above.

[0023] At least one compression chamber of the device can have an undercut. The undercut can laterally and / or radially expand the volume of the compression chamber with respect to a longitudinal axis of the compression chamber. The longitudinal axis of the compression chamber can define the longitudinal orientation of the bristle filaments within the compression chamber.

[0024] The undercut allows the compaction chamber to have a cross-section that is laterally widened with respect to an insertion opening of the compaction chamber and / or with respect to a longitudinal axis of the compaction chamber. This can promote the shaping and compaction of bristle bundles with a cross-sectional shape that, for example, deviates from a circular cross-sectional shape and / or is asymmetrical.

[0025] The undercut of the compaction feature can be an undercut in a cross-section of the compaction feature, which is arranged in a cross-sectional plane oriented perpendicular to a longitudinal axis of the compaction feature.

[0026] The compaction attachments can be moved in a removal and / or compaction motion relative to the delivery device, either transversely or perpendicularly to a longitudinal axis of the bundle notches that defines the longitudinal orientation of the bristle bundles within the bundle notches. This allows the compaction attachments to be guided past the delivery device and its bundle notches, first to remove the bristle bundles from the bundle notches and then to compact them using the compaction device.

[0027] The device can have at least one target plate downstream of the compaction receptacles, which includes target receptacles for receiving the compacted bristle bundles.

[0028] The target plate can be designed, for example, as a cassette and / or as a transport holder for compacted bristle bundles. After its target receptacles have been loaded with compacted bristle bundles, the target plate can then be transferred to a downstream process step for further processing of the bristle bundles.

[0029] The target plates may have insertion chamfers. These insertion chamfers can facilitate the transfer of the compacted bristle bundles from the compaction recesses into the target recesses.

[0030] In a preferred embodiment of the device, the target receptacles of the target plate can be arranged in a hole pattern that corresponds to the arrangement of bristle bundles on a bristle carrier of a bristle product to be manufactured. In this way, it is possible to hold the bristle bundles in the target plate not only with the desired degree of compaction, but also already in the arrangement that the bristle bundles will later assume on a bristle carrier of the bristle product to be manufactured.

[0031] At least one extraction plate of the device can have compaction receptacles arranged in a hole pattern that corresponds to at least a partial hole pattern of the target receptacles of the target plate. In this way, it is possible to transfer the bristle bundles held in the compaction receptacles of an extraction plate of the device directly into the target receptacles of the target plate after compaction. If the compaction receptacles of the device are distributed across more than one extraction plate, it is possible to load the target receptacles of the target plate with bristle bundles sequentially in subgroups.

[0032] The device may include a transfer device for transferring bristle bundles from the compaction receptacles to target receptacles of the aforementioned target plate. The transfer device allows the bristle bundles, arranged and compacted in the compaction receptacles, to be moved into the target receptacles of the target plate. The transfer device may initiate and / or execute a transfer movement oriented along the longitudinal axes of the compaction receptacles, along the longitudinal axes of the target receptacles, and / or along the longitudinal direction of the bristle bundles located in the compaction receptacles.

[0033] The bristle bundles are preferably extracted from the bundle notches of the dispensing device in a removal and / or compaction movement that is / are oriented transversely or perpendicular to their longitudinal direction(s) and / or subsequently compacted using the compaction means. The subsequent transfer of the compacted bristle bundles from the compaction receptacles to the target receptacles of the target plate can then take place in the longitudinal direction of the longitudinal axes of the bristle bundles and thus transversely or perpendicularly to the removal and / or compaction direction.

[0034] The transfer device can have at least one sliding pin with which the bristle bundles can be pushed longitudinally along their longitudinal axes from the compaction recesses into the target recesses of the target plate. Preferably, the transfer device has one sliding pin for each compaction recess. The at least one sliding pin preferably has the same cross-section as the receiving opening to which the sliding pin is assigned and / or as a bristle bundle compacted therein.

[0035] The transfer device can have a pin plate for each extraction plate with a number of sliding pins corresponding to the number of compaction receptacles of the respective extraction plate.

[0036] In this way, it is possible to transfer the bristle bundles located in the compaction recesses of a sampling plate to corresponding target recesses of a target plate in one operation using the pin plate and its sliding pins.

[0037] According to the invention, the at least one extraction plate and / or at least one compaction means has / have a receiving space, namely a slot, in which the dispensing means and / or a, in particular movable, counterpart is positioned during the extraction and / or compaction of bristle bundles.

[0038] The receiving space allows the extraction plate and / or at least one compaction element to be positioned relative to the supply element during the extraction and / or compaction of bristle bundles in such a way that the supply element is at least partially located within the receiving space of the extraction plate and / or the compaction element. This allows the bristle bundles to be contacted, supported, and / or compacted on both sides of the bundle notch of the supply element by the extraction plate and / or the compaction element during extraction and / or compaction.

[0039] The device can have at least one counterpart associated with the dispensing means. This counterpart prevents the loss of bristle bundles located in the bundle notches as they move from a source in a supply to the compaction receptacles. Preferably, the device has at least one movable counterpart in the area of ​​the compaction receptacles, which can be moved from a starting position to a target position relative to the dispensing means during and / or by means of a dispensing and / or compaction movement of the compaction receptacles. This allows the movable counterpart to move out of the way and create space for the movement of the compaction receptacles during the dispensing and / or compaction of the bristle bundles.The movable counterpart can act upon a bundle of bristles located in a compaction receptacle transversely or perpendicularly to its longitudinal axis and / or contact it until the bundle of bristles is acted upon by a compaction agent for compaction.

[0040] The device can include a compartment slide, a compartment disc, a circular arc and / or a compartment ring as a provisioning means.

[0041] To solve the problem, a bristle manufacturing machine, for example a brush manufacturing machine or a broom manufacturing machine or a paintbrush manufacturing machine, is also proposed, which has a device for compacting bristle bundles according to one of the claims directed to such a device.

[0042] To solve the problem, a method for compacting bristle bundles using such a device is also proposed, which includes the means and features of the independent claim directed to such a method. Accordingly, to solve the problem, a method for compacting bristle bundles using a bristle bundle compaction device is proposed, in which bristle bundles provided by the device's delivery means are extracted from the bundle notches of the delivery means by means of the device's compaction receptacles and compacted by means of the device's compaction means. The bristle bundles are preferably compacted to a defined degree of compaction.

[0043] During the process, the bristle bundles can be compacted, for example, to a degree of compaction of 60% to 90%, or to a degree of compaction of 70% to 80%, or to a degree of compaction of 75%.

[0044] During the compaction of the bristle bundles, the compaction agent enters the compaction receptacles through inlet openings and comes into contact with the bristle bundles inside. The bristle bundles can be compacted with the compaction agent transversely and / or perpendicularly to their longitudinal axes.

[0045] In one embodiment of the method, bristle filaments of at least one bristle bundle are pushed into an undercut of a compression recess in the device during the compression of the bristle bundle. This allows the bristle bundle to be reshaped during compression. The bristle bundle can be reshaped during compression to acquire a cross-sectional shape that corresponds to the cross-sectional shape of the compression recess with the undercut. The cross-sectional shape of the compressed bristle bundle can, for example, be a shape that deviates from a circular cross-sectional shape and / or is asymmetrical.

[0046] After compaction, the bristle bundles can be transferred into the target receptacles of a target plate within the device. Using the target plate, the compacted bristle bundles can then be prepared for subsequent processing steps in the production of bristle products. The target plate can be equipped with a bristle carrier. The compacted bristle bundles can then be pushed through the bristle carrier's receptacles with their attachment ends. Finally, the attachment ends can be melted to bond the bristle bundles to the bristle carrier.

[0047] 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 each other and / or in combination with one or more features of the exemplary embodiments. The following are shown: Figures 1-6 show different views of a device for compacting bristle bundles at different stages, the device having two extraction plates, each with two compaction receptacles, arranged on a supply element in the form of a compartment disc with a total of four bundle notches on its circumferential edge.

[0048] In the following description of various embodiments of the invention, elements that are functionally identical are assigned the same reference numerals even if their design or shape differs. Unless otherwise indicated, and where possible, the following description refers to all embodiments of the invention shown in the figures.

[0049] All figures show at least parts of a device for compacting bristle bundles, designated as a whole by 1 2.

[0050] The device 1 has at least one provisioning means 3, namely a bundle divider, with bundle notches 4 and a number of compaction receptacles 5 for bristle bundles 2 that at least corresponds to the number of bundle notches 4, and for each of its compaction receptacles 5 a compaction means 6.

[0051] The compaction receptacles 5 are designed for removing bristle bundles 2 from the bundle notches 4 of the supply means 3 and the compaction means 6 for compacting bristle bundles 2 positioned in the compaction receptacles 5.

[0052] In all embodiments of the device 1 shown in the figures, it has several extraction plates 7 on which the compression receptacles 5 are distributed.

[0053] The in the Figures 1-6 The device 1 shown has a total of two extraction plates 7, each with two compaction receptacles 5. The in the Figures 12-20 The device 1 shown has a total of four extraction plates 7. Two of the extraction plates 7 each have only one compaction receptacle 5, while the remaining two extraction plates 7 each have two compaction receptacles 5.

[0054] The Figures 21-26detailed illustrations show one of the sampling plates 7, which has two differently shaped compaction indentations 5.

[0055] Each compaction receptacle 5 has an insertion opening 8 oriented transversely, namely perpendicular to its longitudinal axis and thus perpendicular to a longitudinal axis of bristle bundles 2 arranged in the compaction receptacles 5, for bristle bundles 2 and also for the compaction means 6. The compaction means 6 are integrally connected to a retaining plate 9, thus forming a materially homogeneous monolithic unit with it.

[0056] The compaction elements 6 have sharp edges at their transitions 10 between their flanks 11 and their end faces 12 facing the respective compaction recesses 5. The sharp edges 10 between the flanks 11 and the end faces 12 of the compaction elements 6 prevent bristle filaments 37 from slipping past the compaction elements 6 and escaping from the compaction recesses 5 during the compaction of the bristle bundles 2.

[0057] The flanks 11 of the compaction material 6 are, as already explained in the general part of the description, smoothed and also hardened.

[0058] The compaction elements 6 each exhibit a measured undersize of 0 µm to 50 µm or 0 µm to 20 µm in one lateral direction of their respective associated compaction receptacle 5 relative to the clear width of the insertion opening 8 of the respective compaction receptacle 5, measured in the same lateral direction. The tolerance range between 0 µm to 50 µm or 0 µm to 20 µm depends on the filament thickness of the bristle filaments 37 from which the bristle bundles 2 consist, which are to be compacted in the compaction receptacles 5.

[0059] For example, the Figures 21-26 The compaction images 5 show an undercut 13. The undercut 13 enables the shaping and compaction of a bristle bundle 2, which has a cross-sectional shape that deviates from a circular cross-sectional shape.

[0060] To remove bristle bundles 2 from the bundle notches 4 of the respective supply device 3, the compaction devices 5, together with their removal plates 7, can be moved past the bundle notches 4 in a transverse direction, i.e., at right angles to a longitudinal axis of the bundle notches 2, which defines the longitudinal orientation of the bristle bundles 2 positioned therein. This is illustrated, for example, by a comparison of the Figures 21 to 23 , in which the compaction recordings 5 ​​with the extraction plates 7 are shown in different relative positions to the bundle notches 4 of the supply means 3 and also to the compaction means 6.

[0061] The compaction of the bristle bundles 2 located in the compaction receptacles 5 is carried out by a compaction movement that continues the extraction movement. For example Figure 24 shows the compaction images 5 in compaction position on the compaction means 6.

[0062] Both the compaction movement and the extraction movement are linear movements of the extraction plates 7 and the compaction recesses 5 formed therein, which are carried out relative to the supply means 3 and the compaction means 6.

[0063] The bristle bundles 2, in their compacted state, are then transferred from the compaction receptacles 5 into a target plate 14 of the device 1. The target plate 14 has target receptacles 15 for receiving the compacted bristle bundles 2.

[0064] Figure 8 illustrates the fitting of the target receptacles 15 of the target plate 14 with bristle bundles 2.

[0065] First, the target plate 14 is fitted with a bristle carrier 200. Then, the individual target receptacles 15 of the target plate 14 are fitted with compacted bristle bundles 2. This is done by pushing the compacted bristle bundles 2 axially from the compaction receptacles 5 of the device 1 into the target receptacles 15 of the target plate 14 in the direction of their longitudinal axes using the transfer device 19 and its sliding pins 20.

[0066] According to Figure 8 The bristle bundles 2 are pushed into bundle receptacles 201 of the bristle carrier 200, so that their fastening ends 202 protrude beyond the bristle carrier 200. In a subsequent processing step, the bristle bundles 2 can be joined to the bristle carrier 200, for example, by melting their fastening ends 202. This can be done, for example, in one of the processing stations 16 of the Figure 7The bristle goods manufacturing machine 17 shown will be used.

[0067] The target plates 14 shown in the figures are designed as cassettes and also serve as transport holders. The target plates 14 thus also serve to transfer the compacted bristle bundles 2 to downstream processing stations 16 of a bristle goods manufacturing machine, designated as a whole by 17, as schematically depicted in Figure 7 It is shown to be transported.

[0068] The sectional view of a target plate 14 from Figure 11The figures show that the target receptacles 15 for receiving the bristle bundles 2 have insertion chamfers 18. The insertion chamfers 18 facilitate the transition of the compacted bristle bundles 2 into the target receptacles 15 of the target plate 14. The target plates 14 shown in the figures have target receptacles 15 formed in a hole arrangement on the target plate 14, corresponding to an arrangement of bristle bundles 2 on the bristle carrier 200 of a bristle product to be manufactured. From the target receptacles 15 of the target plates 14, the bristle bundles 2, compacted to the desired degree of compaction, can thus be provided for connection with the bristle carrier 200 without changing their relative position to one another.

[0069] The extraction plates 7 have compaction receptacles 5, each arranged in a hole pattern that corresponds to at least one partial hole pattern of the hole arrangement of the target receptacles 15 of the target plates 14. This means that the target plates 14 can be used to fill all target receptacles 15, as is the case, for example, in the Figures 1-6 As shown, the different extraction plates 7 and the compaction receptacles 5 formed therein must be moved.

[0070] The target receptacles 15 of the target plate 14 are then successively filled with compacted bristle bundles 2, as is the case, for example, Figure 8 illustrated. The filling of the target receptacles 15 of the target plates 14 also takes place in a similar manner in the Figures 12-20 Device 1 shown. Here, the target plates 14 are moved one after the other to the different removal plates 7 of this device 1 to fill their target receptacles 15.

[0071] All devices 1 shown in the figures also each have at least one transfer device 19. The transfer devices 19 serve to transfer bristle bundles 2 from the compression receptacles 5 into the target receptacles 15 of the target plates 14.

[0072] The transfer devices 19 specify a transfer direction which is aligned in the direction of the longitudinal axes of the compaction receptacles 5 and also in the direction of the longitudinal axes of the target receptacles 15 of the target plates and thus also in the longitudinal direction of the bristle bundles 2 located in the compaction receptacles 5.

[0073] The operation of the transfer devices 19 is explained using the illustrations of the Figures 21-26 clearly.

[0074] The transfer device 19 shown in these figures has sliding pins 20 for transferring the bristle bundles 2 from the compaction receptacles 5 into the target receptacles 15 of the target plates 14. The longitudinal axes of the sliding pins 20 are aligned perpendicular to the insertion direction of the bristle bundles 2 and the compaction media 6 into the compaction receptacles 5.

[0075] In the devices 1 shown in the figures, the transfer devices 19 used for each extraction plate 7 each have a pin plate 21 on which a number of sliding pins 20 are arranged, corresponding to the number of compaction receptacles 5 of the respective extraction plate 7.

[0076] The pin plates 21 have guide pins 35. The extraction plates 9 and the target plates 14 have corresponding guide bores 36. During the transfer of the bristle bundles 2 from the compaction receptacles 5 into the target receptacles 15 of the target plates 14, the guide pins 35 are inserted into the guide bores 36, thus defining the relative positions of the pin plates 21, the extraction plates 9, and the target plates 14. This facilitates a precise transfer of the compacted bristle bundles 2 into the target receptacles 15 of the target plates 14.

[0077] Especially the Figures 21-26 illustrate that both the extraction plates 7 and the compaction agents 6 each have at least one receiving chamber 22. Figures 22 to 24The illustration shows that the supply means 3 is arranged in the receiving chamber 22 of the extraction plate 7 during the extraction and compaction of bristle bundles 2. These receiving chambers 22 are designed as slots in both the extraction plates 7 and the compaction means 6.

[0078] The device 1 further comprises a movable counterpart 23 for each extraction plate 7. The movable counterpart 23 serves to secure bristle bundles 2, which are arranged in the bundle notches 4 of the supply means 3, until the bristle bundles 2 have been removed from the bundle notches 4 and compacted.

[0079] By moving or during a movement of the extraction plate 7 in the direction of the compaction agent 6, according to the Figures 21-26 The movable counterpart 23 is also raised. In doing so, the movable counterpart 23 enters the receiving chamber 22 of the compaction means 6 (see, for example, [reference]). Figures 23, 24as well as 25 and 26) and thus creates space for the compaction of the bristle bundles 2 located in the compaction recesses 5. The movable counterpart 23 secures the bristle bundles 2 in the bundle notches 4 until the compaction agents 6 come into contact with the bristle bundles 2 and fix them in place.

[0080] The devices 1 shown also have counterparts 24 associated with the delivery means 3, which are designed as rigid counterparts. Rigid counterparts 24 are, for example, well suited to the Figures 1-6 to identify and surround the provisioning means 3 at sections of its perimeter. The in the Figures 1-6 The device 1 shown has two rigid counterparts 24 and two movable counterparts 23. The number of movable counterparts 23 thus corresponds to the number of the two removal plates 7.

[0081] The counterparts 23 and 24 ensure that the bristle bundles 2 located in the bundle notches 4 are protected from loss on their way from their extraction from a supply 25 of loose bristle filaments 37 to the compaction receptacles 5. The Figures 1-6 show that at least one movable counterpart 23 is assigned to each of the compaction recordings 5 ​​in the area of ​​the two extraction plates 7 of this device 1.

[0082] The movable counterparts 23 are moved from a starting position to a target position during the extraction and compaction movements of the compaction receptacles 5 and the extraction plates 7. In doing so, the movable counterparts 23 reach the target position and enter the receiving chamber 22 of the compaction elements 6. Figure 1 shows the two movable counterparts 23 of the device 1 in the receiving spaces 22 of the compaction means 6.

[0083] Even those in the Figures 12 to 20The device 1 shown has movable counterparts 23 and rigid counterparts 24.
