Description

Bristle bundle pressing device, brush manufacturing machine and bristle bundle pressing method

The present invention relates to a bristle bundle compacting device for manufacturing brushes, a brush manufacturing machine having such a device and a bristle bundle compacting method.

Publication DE 100 05 249 A1 discloses a brush manufacturing machine, which includes a double feeding device for bristle material (the double feeding device has a bristle strand feeding device), a cut-to-length device for bristle bundles, and A feeding device for feeding the bristle bundles into a device for connecting the bristle bundles to the brush body. The brush making machine is characterized in that the feed device is designed for the individually controllable feeding of the individual bristle strands and has a stepwise positionable transport member with holes for the bristle strands or bristle bundles. , is provided with a feeding device for sending the bristle strands to the stepping position of one of the holes on the conveying member, and is provided with one or more bristle strand feeding devices that cooperate with the conveying member for feeding the bristle strands. Shearing device for cutting strands to length.

To manufacture brushes, for example brushes like toothbrushes, bristle filaments are taken from a supply of loose bristle filaments in the form of bristle bundles by means of a supply member, such as a tuft separator.

For this purpose, the feed member used may have tuft slots through which the feed member is supplied with loose bristle filaments. During this process, a certain number of bristle filaments enter the notches of the bristle bundles. The bristle filaments arranged in a tuft recess together form a bristle tuft.

In the bristle notches, the bristle bundles are not yet formed or compacted. The filament density of the bristle bundles located in the bristle bundle notches is still relatively low, and the bristle bundles do not yet have the shape that they should subsequently have on the finished brush. In order to be used on finished brushes, the filament density of the bristle bundles should be increased, and if necessary, the bristle filaments should be given a certain shape.

Compressing and, if necessary, shaping the bristle bundles means a certain amount of work. In practice, the compaction of the bristle bundles is achieved, for example, by pushing them through a tapering channel of a so-called funnel plate. Precision manufacturing of funnel plates is more expensive but critical to achieving the required compaction. According to the required degree of compression, compression can be carried out in multiple stages. At this time, multiple funnel plates connected in series are required.

The object of the present invention is to provide a bristle bundle pressing device, a brush manufacturing machine and a bristle bundle pressing method, which allow the bristle bundles to be pressed in an efficient and economical manner to produce brushes.

To achieve this object, a device for compressing bristle bundles is first proposed, which device has the characteristics of an independent claim for such a device. In particular, a solution to achieve this object is a bristle bundle compression device, which device has a supply member with a bristle notch (in particular a bristle separator), a compression seat for the bristle bundles and a bristle bundle. Each pressing seat is provided with one pressing member, the number of pressing seats is at least consistent with the number of bristle slots, wherein the pressing seats are configured to remove bristles from the bristle slots of the supply member The pressing member is configured to compress the bristle bundles located in the pressing seat.

The supply member may be used to separate the bristle bundles from a loose supply of bristle filaments and provide the bristle bundles in an as-yet-compacted form. With the help of the pressing seat of the device, the uncompressed bristle bundles can be removed from the bristle notch of the supply member in one working step, and then pressed by the pressing member to the bristle bundle downstream. The desired degree of compaction during the processing step and/or on the finished brush. Brushes can be produced particularly efficiently in this way.

In one embodiment of the device, the pressure seat of the device is formed in one stripper or in two or more strippers of the device.

The pressing member can move transversely to the longitudinal extension direction of the pressing seat to a pressing position on or in the pressing seat through the relative movement of the pressing seat and the pressing member. In this case, the relative movement of the pressure seat and the pressure member can be carried out transversely (especially perpendicularly) to the orientation of the bristle bundles and their longitudinal axis in the bristle bundle notches, which orientation is determined by the bristle bundles of the supply member. stipulated by the orientation of the notch.

The pressing seats may respectively have insertion openings through which the bristle bundles and/or the pressing members may be inserted into the pressing seats. The insertion openings can each be oriented transversely or perpendicularly to the longitudinal axis of the associated pressure seat and/or transversely or perpendicularly to the longitudinal axis of the bundle of bristles arranged in the pressure seat. In this way, in a relative movement transversely or perpendicularly to the longitudinal axis of the bristle bundle, the bristle bundle can first be removed from the bristle bundle notch of the supply member and then compressed in the same direction.

For example, the pressing is carried out as follows: in a pressing movement oriented transversely or perpendicularly to the longitudinal axis orientation of the bundle of bristles arranged in the pressing seat, the pressing member enters the pressing member through the insertion opening of the pressing seat. The bristle bundles located in the compression seat are then acted upon in a compressive manner there.

The insertion opening of the compression seat can be defined by an insertion bevel. Inserting the bevel enables gentle insertion of the compression member into the compression seat of the device and helps avoid damage to the compression member and/or the compression seat.

It should be noted here that the pressing seat can either move by itself to reach the pressing position inside the pressing seat, or can move relative to the pressing member to perform the aforementioned relative movement between the pressing seat and the pressing member. It is also possible that both the pressing seat and the pressing member move to perform relative movement for pressing.

In order to prevent the bristle filaments from leaving the pressing seat during the pressing process, it is advantageous if at least one pressing member has a sharp-edged connection between its side surface and its end face facing the corresponding pressing seat facing the pressing member. . By means of the sharp edge connecting portion between the side surface and the end surface of the pressing member, the pressing member can be designed to fit accurately and tightly with the inner wall of the pressing seat. The sharp edge connection between the side surface and the end surface of the pressing member prevents the bristle filaments arranged in the pressing seat from leaving the pressing seat beside the pressing member during the above-mentioned relative movement for compressing the bristle bundles.

At least one pressing member can be smoothed and/or hardened on at least one side adjacent to the end face of the pressing member facing the pressing seat. The sides may have, for example, a surface roughness of Ra 0.01-1.6, preferably Ra 0.01-0.04, and/or a hardness of depth 1.2-1.8 Rht, 55-63 HRC, preferably 60-63 HRC, in particular the edges. layer hardness.

The pressing members may each have a cross-section, and the measurable width of the cross-section is less than the width of the cross-section of the corresponding pressing seat of the pressing members, which is disposed in the same cross-sectional plane. In this way, the pressing member for pressing the bristle bundle can be inserted into the pressing seat through the insertion opening.

At least one pressure component of the device may have an undersize of 0 µm to 50 µm, in particular an undersize of 0 µm to 20 µm, measurable in the width direction of its associated pressure seat, which The insufficient size is relative to the clear width that can be measured in the same width direction of the insertion opening of the compression seat corresponding to the compression member.

The above-mentioned tolerance range of this undersize can depend, for example, on the thickness of the bristle filaments of the bundle of bristle to be pressed. For a bristle filament with a thickness of 3 mil, the tolerance range may be, for example, 0 µm to 20 µm. In the case of larger filament thicknesses, i.e. for bristle filaments with a thickness of 8 mil, for example, a relatively larger tolerance range (e.g. a tolerance range of 0 µm to 50 µm) may be sufficient to achieve the above dimensional deficiencies.

At least one compression seat of the device may have an undercut. This undercut can expand the volume of the pressure seat laterally and/or radially relative to its longitudinal axis. The longitudinal axis of the pressure seat can define the longitudinal orientation of the bristle filaments in the pressure seat.

The undercut enables the pressure seat to have a laterally expanded cross-section relative to the insertion opening of the pressure seat and/or relative to the longitudinal axis of the pressure seat. This facilitates, for example, the shaping and compacting of bristle bundles with a cross-sectional shape that differs from a circular cross-sectional shape and/or asymmetric cross-sectional shapes.

The lower cutout of the pressure seat may be a lower cutout of the pressure seat in a cross-section arranged in a cross-sectional plane oriented perpendicularly to the longitudinal axis of the pressure seat.

The pressure seat is capable of a removal movement and/or a pressure movement oriented transversely or perpendicularly to the longitudinal axis of the bristle notch, which defines the longitudinal orientation of the bristle bundles in the bristle notch, relative to the supply member. Make a move. In this way, the pressing seat can be guided through the supply member and its bristle notch, so that the bristle bundle is first removed from the bristle notch and then compressed by the pressing member.

The device may have at least one target plate located downstream of the pressing seat, the target plate including a target receiving portion for receiving the compressed bristle bundles.

The target plate can be designed, for example, as a box and/or as a transport holder for the compressed bristle bundles. After the compacted bristle bundles have been loaded into their target receptacles, the target plate can be sent to downstream process steps for further processing of the bristle bundles.

The target receiving portion of the target board may have an insertion bevel. Inserting the bevel enables the compressed bristle bundles to be transferred more easily from the compression seat to the target receptacle.

In a preferred embodiment of the device, the target receiving portion of the target plate can be arranged according to the hole arrangement corresponding to the arrangement of the bristle bundles on the bristle carrier of the brush to be made. In this way, it is possible to ensure that the bristle bundles not only have the required compaction in the target plate, but also are arranged according to the subsequent arrangement of the bristle bundles on the bristle carrier of the brush to be made.

At least one retrieval plate of the device may have pressing seats arranged according to a hole pattern corresponding to at least one partial hole pattern of the hole arrangement of the target receiving portion of the target plate. In this way, the bristle bundles in the pressing seat of the pickup plate of the device can be directly transferred to the target receiving portion of the target plate after being pressed. If the pressing seats of the device are distributed on more than one pick-up plate, the bristle bundles can be loaded into the target accommodating portion of the target plate sequentially in a grouped manner.

The device may have a transfer device for transferring the bristle bundles from the pressing seat to the target receiving portion of the target plate. The compressed bristle bundles arranged in the pressing seat can be moved to the target receiving portion of the target board by the transfer device. The transfer device can define and/or execute a transfer movement in the direction of the longitudinal axis of the pressure seat and/or in the direction of the longitudinal axis of the target receptacle and/or in the longitudinal orientation of the bristle bundles located in the pressure seat.

The bristle bundles are preferably removed from the bristle bundle notches of the supply member in a removal movement and/or a pressing movement oriented transversely or perpendicularly to the longitudinal extent of the bristle bundles and/or are subsequently pressed by the pressing member. The compacted bristle bundle is then transferred from the compaction seat to the target receptacle of the target plate. This transfer can be carried out in the longitudinal direction of the longitudinal axis of the bristle bundle, that is, transversely or perpendicularly to the removal direction and/or compaction. proceed directionally.

The transfer device can have at least one sliding pin, by means of which the bristle bundle can be pushed longitudinally along its longitudinal axis from the pressing seat into the target receptacle of the target plate. The transfer device preferably has one sliding pin for each pressing seat. The at least one sliding pin preferably has the same cross-section as the receiving opening corresponding to the sliding pin and/or the compressed bristle bundle therein.

The transfer device may have a pin plate provided for each scraper plate, and the pin plate has a certain number of sliding pins, which number corresponds to the number of pressing seats of the relevant scraper plate.

In this way, the bristle bundles located in the pressing seats of a retrieval plate can be transferred from the pressing seats to the corresponding target receiving portion of a target plate by means of the pin plate and its sliding pin.

The at least one removal plate and/or the at least one pressing member can have a receiving space, for example a slit, in which the supply member is located during removal of the bristle bundle.

This accommodation space makes it possible to position the removal plate and/or the at least one pressing member relative to the supply member during removal and/or compression of the bristle bundle, such that the supply member is at least partially arranged on the removal plate and/or Or in the accommodation space of the compression member. In this way, the bristle bundles can be contacted, supported and/or compressed by the fetching plate and/or the pressing member from both sides of the bristle bundle notch of the supply member during the process of extracting and/or pressing.

The device may have at least one counterpart corresponding to the supply member. The bristle tufts located in the bristle tuft notches can be secured by the fitting to prevent loss when being removed from the supply and transported to the pressing seat. The device preferably has at least one movable fitting in the area of the pressing seat, which movable fitting can be used during the removal and/or pressing movement of the pressing seat relative to the supply member and/or can be moved by the pressing seat. Moving from the initial position to the target position relative to the picking movement and/or pressing movement of the supply member. This allows the movable fitting to get out of the way to create room for movement of the pressing seat during removal and/or pressing of the bristle bundle. The movable fitting member can exert an effect on the bristle bundle located in the compression seat transversely or perpendicularly to the longitudinal axis of the bristle bundle and/or contact the bristle bundle before the bristle bundle is exerted a compression effect by the compression member.

The device can have a separating slide, a separating disk, a circular arc and/or a separating ring as supply components.

In order to achieve the aforementioned object, a brush manufacturing machine is also proposed, such as a brush manufacturing machine or a broom manufacturing machine or a brush manufacturing machine, which brush manufacturing machine has a bristle bundle as described in one of the claims regarding a bristle bundle compression device. Hold down device.

In order to achieve the aforementioned object, a method of using such a device to compress the bristle bundles is also proposed, which method has the means and characteristics of the independent claim for such a method. Accordingly, a solution to achieve this object is a method of compressing bristle bundles using a bristle bundle compression device, in which the bristles provided by a supply member of the device are compressed by means of a compression seat of the device The tufts are taken from the tuft slots of the supply member and compressed by means of the compression member of the device. Among them, it is preferable to compress the bristle bundles to a certain degree of compression.

When carrying out this method, the bristle bundles may be compacted, for example, to a compaction degree of 60% to 90%, a compaction degree of 70% to 80%, or a compaction degree of 75%.

During the process of compressing the bristle bundles, the pressing member enters the pressing seat through the insertion opening of the pressing seat and comes into contact with the bristle bundles located therein. The compression member may exert a compression effect on the bristle bundle transversely and/or perpendicularly to the longitudinal axis of the bristle bundle.

In one embodiment of the method, the bristle filaments of at least one bristle bundle are pushed into the lower cutout of the pressing seat of the device during the compression of the bristle bundle. This allows the bristle bundles to be shaped as they are compressed. During the pressing process, the bristle bundles can be shaped to obtain a cross-sectional shape corresponding to the cross-sectional shape of the pressing seat with the lower cutout. The cross-sectional shape of the compressed bristle bundles may, for example, be different from a circular cross-sectional shape and/or be asymmetrical.

The bundles of bristles can be compressed and transferred to the target receiving portion of the target plate of the device. By means of the target plate, the bristle bundles that have been compacted as required can be provided to the downstream process steps for manufacturing the brush. The target board can be equipped with a bristle carrier. Then the fastening side end of the compressed bristle bundle can be passed through the bristle bundle receiving portion of the bristle carrier. The fastening side ends can then be melted to connect the bristle bundles to the bristle carrier.

In the following description of various embodiments of the present invention, elements with the same function are labeled with the same reference numerals even if they have different designs or shapes. Wherever possible, the following description relates to all embodiments of the invention shown in the drawings, unless stated otherwise.

All figures show at least some parts of a device for compressing bristle bundles 2 , which device is designated as a whole with 1 .

The device 1 has at least one supply element 3 (ie a bristle separator) with a bristle tuft slot 4 , a pressure seat 5 for the bristle tufts 2 and a pressure element 6 for each pressure seat 5 . , the number of pressing seats is at least consistent with the number of hair bundle notches 4.

The pressing seat 5 is provided for removing the bristle bundles 2 from the bristle bundle notches 4 of the supply member 3 , and the pressing member 6 is provided for pressing the bristle bundles 2 located in the pressing seat 5 .

In all the embodiments of the device 1 shown in the figures, the device has a plurality of removal plates 7 on which the pressing seats 5 are distributed.

The device 1 shown in Figures 1 to 6 has a total of two take-out plates 7 with two pressing seats 5 each. The device 1 shown in Figures 12-20 has a total of four pickup plates 7. Two of the scraping plates 7 each have only one pressing seat 5 , while the remaining two scraping plates 7 each have two pressing seats 5 .

Figures 21 to 26 show detailed views of one of the stripping plates 7, which has two pressing seats 5 of different shapes.

Each pressure seat 5 has an insertion opening 8 for the bristle bundle 2 and also for the pressure element 6 , which insertion opening 8 is oriented transversely (that is, perpendicularly) to the longitudinal axis of the pressure seat and thus perpendicularly to the longitudinal axis arranged on the pressure seat. The longitudinal axis of the bristle bundle 2 in the tight seat 5 is oriented. The pressing member 6 is integrally connected to the retaining plate 9 , ie forms a homogeneous one-piece unit with the latter.

The pressing member 6 adopts a sharp edge design at the connecting portion 10 between its side surface 11 and its end surface 12 facing the associated pressing seat 5 . The sharp edge connection 10 between the side 11 and the end face 12 of the pressing member 6 prevents the bristle filaments 37 from sliding through the pressing member 6 from the pressing seat 5 and leaving the pressing seat during the process of pressing the bristle bundle 2 5.

The side surfaces 11 of the pressing member 6 are smoothed and hardened, as explained in the general part of the description.

The pressing members 6 respectively have a dimensional deficiency of 0 µm to 50 µm or 0 µm to 20 µm that can be measured in the width direction of their respective corresponding pressing seats 5 , and the dimensional deficiency is relative to the relevant pressing seat 5 In terms of the clear width of the insertion opening 8 that can be measured in the same width direction. The tolerance range of 0 µm to 50 µm or 0 µm to 20 µm depends on the thickness of the bristle filaments 37 forming the bristle bundle 2 to be compressed in the compression seat 5 .

For example, FIGS. 21-26 show a compression seat 5 with a lower cutout 13 . By means of the lower cutouts 13 , bristle bundles 2 having a cross-sectional shape different from a circular cross-sectional shape can be shaped and compressed.

In order to remove the bristle tufts 2 from the bristle tuft notches 4 of the supply member 3 , the pressing seat 5 together with its removal plate 7 can be moved transversely (ie perpendicularly) to the longitudinal axis of the bristle tuft notches 4 The direction (which defines the longitudinal orientation of the bristle bundles 2 located therein) passes through the bristle bundle notches 4 . This is clear, for example, by comparing Figures 21 to 23, in which the pressing seat 5 together with the removal plate 7 is positioned relative to the bristle notch 4 of the supply member 3 and relative to the pressing The components 6 are in different relative positions.

The compression of the bristle bundles 2 located in the compression seat 5 is achieved through the compression movement, which is a continuation of the material taking movement. For example, Figure 24 shows the compression seat 5 in the compression position at the compression member 6.

Both the pressing movement and the material taking movement are linear movements of the material taking plate 7 and the pressing seat 5 formed therein relative to the supply member 3 and the pressing member 6 .

Subsequently, the bristle bundle 2 is transferred in the pressed state from the pressure seat 5 into the target plate 14 of the device 1 . In order to receive the compressed bristle bundles 2 , the target plate 14 has a target receiving portion 15 .

FIG. 8 illustrates how the bristle bundle 2 is installed into the target receiving portion 15 of the target plate 14 .

First, the target plate 14 is assembled with the bristle carrier 200 . The compressed bristle bundles 2 are then loaded into each target receiving portion 15 of the target plate 14 . This is achieved by: using the transfer device 19 and its sliding pin 20 to axially push the pressed bristle bundle 2 from the pressing seat 5 of the device 1 along its longitudinal axis into the target receiving portion 15 of the target plate 14 .

As shown in FIG. 8 , the bristle bundle 2 is pushed into the bristle bundle receiving portion 201 of the bristle carrier 200 in this process, and its fastening side end 202 protrudes from the bristle carrier 200 . In a subsequent processing step, the bristle bundle 2 can be connected to the bristle carrier 200 by, for example, melting the fastening side ends 202 . This can be done, for example, on one of the processing stations 16 of the brush manufacturing machine 17 shown in FIG. 7 .

The target board 14 shown in the figures is designed as a box and serves as a transport stand. The target plate 14 is therefore also used to transport the compressed bristle bundles 2 to the downstream processing station 16 of a brush manufacturing machine, which is generally designated 17 as shown schematically in FIG. 7 .

As shown in the cross-sectional view of the target plate 14 in FIG. 11 , the target accommodating portion 15 for accommodating the bristle bundle 2 has an insertion bevel 18 . Inserting the bevel 18 facilitates the transfer of the compressed bristle bundles 2 into the target receptacle 15 of the target plate 14 . The target board 14 shown in the figure has target receiving portions 15, and these target receiving portions are formed on the target board 14 in a hole arrangement corresponding to the arrangement of the bristle bundles 2 on the bristle carrier 200 of the brush to be made. . In this way, the bristle bundles 2 compressed to the required compaction degree can be provided from the target receiving portion 15 of the target plate 14 and will be connected to the bristle carrier 200 without having to change their relative positions to each other.

The scraping plate 7 has pressing seats 5 which are respectively arranged according to hole patterns corresponding to at least one partial hole pattern of the hole arrangement of the target accommodating portion 15 of the target plate 14 . This situation requires that the target plate 14 must be moved to different pickup plates 7 and the pressing seats 5 formed therein, as shown in FIGS. 1 to 6 , for example, in order to fill all the target receiving portions 15 .

The target receptacles 15 of the target plate 14 are then filled sequentially with the compressed bristle bundles 2 , see for example FIG. 8 . In the device 1 shown in FIGS. 12 to 20 , the target receiving portion 15 of the target plate 14 is also filled in a similar manner. Here, the target plate 14 is sequentially moved to different picking plates 7 of the device 1 to fill its target receiving portion 15 .

All devices 1 shown in the figures also have at least one transfer device 19 . The transfer device 19 is used to transfer the bristle bundle 2 from the pressing seat 5 into the target receiving portion 15 of the target plate 14 .

The transfer device 19 thus defines a transfer direction which is oriented along the longitudinal axis of the pressure seat 5 and also along the longitudinal axis of the target receptacle 15 of the target plate and thus also along the longitudinal axis of the pressure seat 5 The longitudinal orientation of the bristle bundles 2.

The working mode of the transfer device 19 can be clearly understood from the illustrations in FIGS. 21 to 26 .

The transfer device 19 shown in these figures has a sliding pin 20 for transferring the bristle bundle 2 from the pressing seat 5 to the target receptacle 15 of the target plate 14 . The longitudinal axis of the slide pin 20 is oriented at right angles to the direction of insertion of the bristle bundle 2 and the pressure element 6 into the pressure seat 5 .

In the device 1 shown in the figure, the transfer device 19 used has a pin plate 21 provided for each pickup plate 7, and a certain number of sliding pins 20 are arranged on the pin plate, the number is equal to the number of sliding pins 20. The number of pressing seats 5 of the relevant scraping plate 7 corresponds to that of the corresponding ones.

The pin plate 21 has guide pins 35 . The pickup plate 7 and the target plate 14 have corresponding guide holes 36 . When the bristle bundle 2 is transferred from the pressing seat 5 to the target receiving portion 15 of the target plate 14, the guide pin 35 is inserted into the guide hole 36, thereby determining the distance between the pin plate 21, the pickup plate 7 and the target plate 14. relative position. This facilitates accurate transfer of the compressed bristle bundles 2 into the target receiving portion 15 of the target plate 14 .

Especially as shown in FIGS. 21 to 26 , both the picking plate 7 and the pressing member 6 each have at least one accommodation space 22 . As shown in FIGS. 22 to 24 , the supply member 3 is arranged in the accommodation space 22 of the removal plate 7 during the process of removing and compressing the bristle bundle 2 . The receiving space 22 of the picking plate 7 and the pressing member 6 is designed as a gap.

The device 1 further has a movable fitting 23 provided for each pickup plate 7 . The movable fitting part 23 is used to fix the bristle bundle 2 arranged in the bristle bundle notch 4 of the supply member 3 and prevent it from being lost until the bristle bundle 2 is removed from the bristle bundle notch 4 and pressed.

According to FIGS. 21 to 26 , by moving the picking plate 7 toward the pressing member 6 or when the picking plate 7 moves toward the pressing member 6 , the movable fitting part 23 can also be lifted. During this process, the movable fitting part 23 enters the receiving space 22 of the pressing member 6 (for example, see FIGS. 23, 24, and 25 and 26), thereby creating a space for compressing the bristle bundles 2 located in the pressing seat 5. space. The movable fitting 23 thereby fixes the bristle bundle 2 in the bristle bundle notch 4 until the pressing member 6 contacts the bristle bundle 2 and fixes it.

The device 1 shown also has fittings 24 corresponding to the supply member 3, these fittings being designed as fixed fittings. The fixed fitting 24 is clearly illustrated in FIGS. 1 to 6 , for example, and surrounds the supply member 3 on some of its circumferential sections. The device 1 shown in Figures 1 to 6 has two fixed fitting parts 24 and two movable fitting parts 23. Therefore, the number of movable fitting parts 23 is consistent with the number of two picking plates 7 .

The bristle bundles 2 located in the bristle bundle notches 4 are fixed by fitting pieces 23 and 24 to prevent loss when they are taken out from the supply 25 of loose bristle filaments 37 and transported to the pressing seat 5 . As shown in Figures 1 to 6, in the area of the two picking plates 7 of the device 1, each of the pressing seats 5 corresponds to at least one movable fitting part 23.

During the material picking and pressing movements of the pressing seat 5 and the picking plate 7, the movable fitting 23 moves from the initial position to the target position. Among them, the movable fitting part 23 at the target position enters the accommodation space 22 of the pressing member 6 . In FIG. 1 , the two movable fitting parts 23 of the device 1 are located in the accommodation space 22 of the pressing member 6 .

The device 1 shown in Figures 12 to 20 also has a movable fitting part 23 and a fixed fitting part 24.

In the device 1 shown in Figures 1-6, the supply member 3 is designed as a separation ring. The breakaway ring is also illustrated in the single part view of Figure 32. The separation ring can also be replaced by an arc or a separation disk as shown in Figure 33.

Figures 12-20 show a device 1 with a further embodiment of a supply member 3 designed as a separation slide and capable of supplying 25 loose bristle filaments 37 formed in the take-off plate 7 The pressing seats 5 move back and forth with alternating linear motion.

The supply member 3 of the device 1 shown in Figures 1 to 6 moves in an alternating pivoting movement. This can be seen from the arrows corresponding to the supply member 3, which indicate the direction of rotation of the supply member 3 in the respective figures.

Each device 1 shown has a magazine 26 in which a supply 25 of loose bristle filaments 37 is arranged.

Figure 7 shows a brush making machine generally designated 17. The brush making machine 17 has a total of four devices 1 for removing the bristle bundles 2 and then compressing them. The brush manufacturing machine 17 has a conveying device 27 that includes a closed conveying track 28 and a plurality of conveying carriages 29 with conveying seats 30 that can move along the conveying track 28 . By means of the transfer carriage 29 and its transfer seat 30 , the target plate 14 equipped with the compressed bristle bundles 2 can be transferred from the device 1 to the downstream processing station 16 of the brush manufacturing machine 17 .

The device 1 shown in the figure is suitable for carrying out the method of compacting bristle bundles 2 described below.

First, the uncompressed bristle bundles 2 are taken out of the supply 25 of loose bristle filaments 37 by means of the supply element 3 of the device 1 and made ready for removal and compaction. Then, with the help of the pressing seat 5 of the device 1, the bristle bundle 2 is first removed from the bristle bundle notch 4 of the supply member 3, and then pressed to a certain pressing degree.

Depending on the required compaction, the bristle bundles 2 can be compacted to a compaction of, for example, 60% to 90%, 70% to 80% or 75%.

For example, as shown in Figures 1 to 6, Figures 16 and 17, and Figures 18 and 19, when this method is implemented, the bristle filaments 37 of at least one bristle bundle 2 are pushed during the process of the bristle bundle 2 being compressed. into the lower cutout 13 of one of the pressing seats 5 of the device 1. FIG. 17 shows the details marked with circles in FIG. 16 in an enlarged view. It can be clearly seen that the bristle bundle 2 with the bristle filaments 37 has been arranged in the receiving recess 5 of the removal plate 7 but has not yet been pressed. There is still a certain distance between the bristle bundle 2 and the pressing member 6 that has passed through the insertion opening 8 of the pressing seat 5 and entered the pickup plate 7 .

FIG. 19 shows the details marked with circles in FIG. 18 in an enlarged view. By further raising the pickup plate 7, the bristle bundles 2 together with their bristle filaments 37 contact the pressing member 6 and are pressed. It can be clearly seen that the bristle filaments 37 of the bristle bundle 2 located inside the pressing seat 5 in Figure 19 enter the lower cutout 13 of the pressing seat 5 during the pressing process. The lower cutout 13 is very important for obtaining the cross-sectional shape of the bristle bundle 2 as shown in FIG. 19 . Among them, the cross-sectional shape of the bristle bundle 2 shown in Figure 19 is different from the circular cross-sectional shape.
