Description

Brush making machine and method for inserting tufts of bristles into openings of a tuft carrier

The present invention relates to a brush manufacturing machine and a method for manufacturing a brush.

Different means and methods are known for inserting tufts or tufts of bristles into the brush body. In particular, for brushes, in which expensive bristle bundle arrangements are used, such as toothbrushes having bristle bundles of different orientations and bristle bundles of different bristles, it is very complicated to fit the bristle bundles into the corresponding openings.

The object of the invention is to make it possible to manufacture brushes at low cost, reliably and flexibly, in particular for toothbrushes.

In order to achieve the object, a brush manufacturing machine is provided according to the present invention, which includes: a holder for holding a bristle carrier; a bristle storage container; and a bundle receiver provided with at least two bundle accommodating on the outer edge of the bundle receiver A groove, the at least two bundle receiving grooves corresponding to the bristle carrier, wherein the bundle receiver interacts with the bristle storage container; and a mechanical insertion device that inserts the bristle bundles in the bundle receiving groove outside of the bundle receiver, which is generally perpendicular The adjustment direction of the edge is pushed toward the holder in the direction of the adjustment direction. To achieve this, a method is also proposed according to the invention for inserting tufts of bristles into the opening of the tuft carrier, in particular by means of a brush-making machine of the aforementioned type, The method has the following steps: The bristles forming the tuft of bristles are supplied to a tuft receiver provided with at least two tuft receiving grooves. The beam carrier is suitably positioned relative to the beam receiver. The bristle bundles of the two bundle receiving grooves are mechanically inserted into at least one opening of the bundle carrier.

The invention is based on the idea that a bundle receiver is used to pre-form two or more bristle bundles, especially in terms of mutual spacing. In this way, multiple tufts of bristles can be placed directly and simultaneously in the tuft carrier.

According to a design solution of the present invention, a plurality of beam receivers are provided. This can increase the clock rate on the one hand. On the other hand this makes it possible to efficiently assemble very complex opening patterns on the bundle carrier.

According to a design solution of the present invention, the beam receiver is a beam receiving wheel. This can in particular be further adjusted in a single direction of rotation, so that a plurality of different beam receiving grooves can be provided along the circumference of the beam receiving wheel.

According to an alternative design solution of the present invention, the beam receiver is a beam-receiving slide plate that can be moved in translation. This results in a very compact structure.

According to another alternative design, the beam receiver is a beam receiving rocker arm that can be adjusted by rotating back and forth. In this design, a component that is known in terms of basic characteristics and thus proven can be used as a beam receiver.

According to a design solution of the present invention, a plurality of holders and a holder driver are provided, and the holder driver can adjust the holder relative to the beam receiver. The holder driver ensures that the holder is correctly positioned relative to the bundle receiver so that the bristle bundles located in the bundle receiver can be inserted into the opening provided for the bristle bundles.

It is preferably proposed that the holder driver is a holder indexing driver, which further adjusts the holder evenly. In this way, low control costs are incurred.

According to a preferred embodiment of the present invention, it is proposed that the holder is adjustably arranged on the holder driver. In this way, the holder can be individually oriented relative to the beam receiver. This can be achieved by means of a retainer positioning drive, ie both in the direction of adjustment of the retainer and transverse to this direction. Furthermore, the holder can be rotated so that the bristle bundles can be placed on the holder in different orientations.

It is also possible to position the holder separately with respect to the beam receiver by providing a beam receiver positioning driver and adjusting the beam reception by the position of the beam receiver positioning driver relative to the holder or the holder Device. This has a structural advantage because the beam receiver positioning driver is implemented substantially fixedly, while the holder positioning driver is arranged around the holder driver.

If desired, the insertion device and other components can also be adjusted by the beam positioning driver, which other components participate in the insertion of the beam into the opening of the beam carrier.

According to a preferred embodiment of the present invention, it is proposed that the beam receiving grooves are different from each other in terms of contour and / or cross section. As a result, different bristle bundles can already be preformed in the bundle receiver.

Preferably, the beam receiver is provided with a plurality of sets of beam receiving grooves at an outer edge of the beam receiver. This can increase the clock frequency of the brush maker Rate, because it is not necessary to adjust the beam receivers periodically between the insertion of two tufts of bristles, but only from one set of beam receiving grooves to the next.

Here, it is preferably proposed that each group of beam receiving grooves is different from each other in terms of the outline of the beam receiving grooves, the cross section of the beam receiving grooves, and / or the number of the inner bundle receiving grooves. Very different beam patterns can be created on the brush with different beam receiving groove groups on the beam receiver.

According to an embodiment of the present invention, it is proposed that the beam receiving groove has a non-circular profile at least in part. Such a profile makes it possible to pre-form rectangular, oval, triangular, or other tufts of bristles in the tuft receiver, which tufts are placed in corresponding openings in the holder.

According to a preferred embodiment of the present invention, a plurality of bristle storage containers are provided. As a result, the brushes can be equipped with different bristles at low cost. Here, "different bristles" means that the bristles are different from each other in terms of material, color, diameter, and / or other physical characteristics.

Preferably, an adjustment drive is provided for the storage container, with which the bristle storage container can be adjusted relative to the beam receiver. Adjusting the driver makes it possible to appropriately arrange a bristle storage container equipped with a desired type of bristles on the bundle receiver at each desired point in time.

According to a design solution of the present invention, a filling station is provided to fill the bristle storage container with bristles. This allows the brush making machine to run automatically.

In addition, a welding table can be provided to weld the bristles. Here, the bristles can be welded together with the adjacent bristles and / or with the material of the holder, so that the bristles are fixedly received in the holder.

A final processing station can also be provided to cut, trim and / or round the bristles. It is no longer necessary to supply a holder with tufts of bristles to a separate device to perform these steps in the device.

Basically, mechanically or chemically pre-sharpened bristles can also be used. Similarly, pre-rounded bristles can be processed. In this case, rounding at the final processing table is omitted.

According to a preferred embodiment of the present invention, an introduction aid having at least one beam guide opening is provided between the beam receiver and the holder. The introduction aid can easily introduce the bristle bundles in the bundle receiving grooves into the openings of the holder.

The lead-in aid can be used to properly "push" the beam upon insertion, thereby compensating for deviations between the position of the beam in the beam receiver and the position of the opening in the beam holder. For this purpose, for example, a beam guide opening can be used which extends obliquely through the introduction aid.

The side of the beam guide opening facing the beam receiver matches the contour and cross section of the corresponding beam receiving groove in terms of the profile of the side and the cross section of the side. This ensures that the bristle bundles in the bundle receiving grooves can be inserted into the bundle guide openings. Support for inserting tufts of bristles by setting the introduction bevel.

According to a design solution of the present invention, it can be provided that a profile of a side of the beam guide opening facing away from the beam receiver is different from a profile of a side of the beam guide opening facing the beam receiver. In this embodiment, the introduction aid is used to transform the bristle bundles held in the bundle accommodation grooves and having a cross-section predetermined by the outline of the bundle accommodation grooves into bristle bundles having another profile.

According to a design solution of the present invention, it can also be provided that the beam guide opening extends at least on the side facing away from the beam receiver in a direction that deviates from the extension direction of the bristle bundle held in the beam receiving groove. This embodiment is particularly advantageous when the openings to be filled in the holder are oriented obliquely to the direction in which the bristle bundles are held in the bundle receiving grooves. It is not necessary to position the holder at an appropriate angle to insert the tufts of bristles, but the required turning can be achieved directly by means of the tuft guide opening of the introduction aid.

It may also be proposed that the introduction aid has two or more separate beam guide openings on the side facing the beam receiver, which beam guide openings are integrated into a single beam guide on the side facing away from the beam receiver Opening. In this design scheme, the introduction aid can be used to collect two bristle bundles having better different bristles into a single bristle bundle, and the bristle bundle is placed in a corresponding opening in the holder.

The introduction aid may also have a large beam guide opening in which a plurality of beams are assembled, which are then inserted into a common opening in the beam carrier.

According to one embodiment of the invention, it is proposed that the holders are successively filled with different tufts of bristles, wherein the holders are repositioned between a single assembly procedure. This ensures that the holders for the tufts of bristles to be inserted are each optimally oriented.

According to one embodiment of the invention, it is proposed that the holders are adjusted relative to the beam receivers, wherein the spacing of the individual beam receivers from one another is slightly different from further adjusting the displacement of the holders in each step.在 该 实 In the real This embodiment results in a low cost for further adjustment (indexing) of the holders, as the holders are all further adjusted for the same displacement. This can be achieved, for example, by the holders being connected to one another. The openings arranged at different positions of the beam carrier are "driven" in this design by the fact that each individual beam receiver is positioned differently from the predetermined position of the beam carrier, when the beam carrier is assisted by means of a holder When positioned on each beam receiver, the beam carriers each have the predetermined position.

The beam receiver can be arranged on the beam receiver positioning driver, by which the beam receiver (and other components such as insertion devices and introduction aids if necessary) can be oriented toward a desired position .

According to an alternative embodiment, it is proposed that the holders are adjusted together by means of a holder drive, but are additionally positioned separately with respect to the respective beam receiver, for example by means of a holder positioning drive. In this design, each bundle carrier is positioned on a respective bundle receiver, so that the opening to be assembled is appropriately oriented relative to the bristle bundle located in the respective bundle receiving groove.

According to a preferred embodiment, it is proposed that at least two beam receivers are provided, and each of the at least two beam receivers has at least two beam receiving grooves, wherein the first and second beam receivers are located in the first beam receiving grooves. The bristle bundle is simultaneously inserted into a corresponding opening of the bundle carrier, and then the bundle receiver is further adjusted so that the second bundle receiving grooves of the first and second bundle receivers correspond to the bundle carrier, wherein the bristle bundles of the second bundle receiving groove At the same time it is inserted into the next opening of the bundle carrier. Here, the concept of "simultaneous" does not mean two bristles The insertion of the beam must occur exactly at the same point in time (in the sense of a fraction of a second), but in the same cycle or step, ie, between further adjustment of the beam receiver from one position to the next.

Ten beam receiving wheels used in; FIGS. 9a to 9c illustrate a brush making machine according to another embodiment in a different state when assembling a bristle carrier; 10a to 10c illustrate another modification of the brush manufacturing machine illustrated in FIG. 9; and FIG. 11 schematically illustrates a brush manufacturing machine according to another embodiment.

Some basic components of a brush making machine according to the present invention are illustrated in FIGS. 1 and 2. For each insertion station, these components are a beam receiver 10, a bristle storage container 20, an insertion device 40, and a holder 50 for holding the beam carrier 5, which are implemented as a beam receiving wheel, which should be provided Bunches of bristles. In addition, the introduction aid 30 is illustrated.

The bundle carrier 5 comprises a plurality of openings 6 which should be fitted with tufts of bristles.

When the toothbrush should be manufactured by a brush manufacturing machine, the bundle carrier 5 may be the head of the toothbrush body, and the bristle bundle is directly inserted into the head.

The bundle carrier 5 can also be a small carrier plate whose openings 6 are provided with bristle bundles. The bundle of bristles can be fixed on the bundle carrier, for example, by welding or gluing, and then placing the bundle carrier on the toothbrush body, or encapsulating it with plastic, so that the bundle carrier becomes part of the toothbrush body.

The bundle carrier 5 can also be equipped with additional components, such as rubber or soft plastic parts.

The bundle carrier 5 may also be, for example, an intermediate carrier made of metal, which holds the bristle bundles until further processing, for example, until the bristle bundles are directly squeezed and encapsulated by the material forming the toothbrush body, thereby the bristles The beam is fixed there.

Generally speaking, the bundle carrier 5 is an arbitrary component provided with an opening, and a plurality of bristle bundles should be placed in the opening. The bundle carrier 5 may be a subsequent part of the brush to be manufactured, or it may only temporarily hold the bristle bundles until the bristle bundles are connected to the brush to be manufactured.

The openings 6 in the beam carrier 5 may have different and mutually different profiles. Basically, all the openings 6 may have a circular contour with the same diameter. However, the brush making machine also makes it possible to assemble more complicated opening patterns (see especially FIG. 2). As an example, two elongated openings with different sizes and two circular openings with different sizes or cross sections are illustrated here. Each opening 6 should receive a tuft of bristles 14, wherein the cross-section of the tuft of bristles corresponds to the cross-section or contour of the corresponding opening 6.

In the illustrated embodiment, the beam receiver 10 is implemented as a beam receiving wheel or a beam receiving disc. The beam receiving wheel 10 is positioned so that the beam receiving wheel is rotatable about a central axis of the beam receiving wheel. For this purpose, a driver (not shown in the drawings) is provided. The driver can be, for example, a servo driver, by which the desired angle of rotation can be precisely adjusted in a controlled manner by the driver beam receiving wheel 10.

In particular, the beam receiving wheel 10 is adjusted in a single direction (see, for example, the arrow in FIG. 2).

Each beam receiving wheel 10 is provided with at least two beam receiving grooves 12 (only one beam receiving groove 12 is illustrated for clarity in FIGS. 1 and 2), which correspond to the beam carrier. As a result, at least two bristle bundles can be assembled at the same time for a bundle carrier.

Each beam receiving groove 12 is arranged on the outer circumference of the beam receiving wheel 10 such that the beam receiving groove opens toward the outer circumference of the beam receiving wheel 10. In other words: each beam receiving groove 12 is an interruption of the circumference of the beam receiving wheel 10. When referring to the geometry of the beam receiving groove 12 below, it is always assumed that the radially outer side of the contour is formed by a virtual continuation of the circumference of the beam receiving wheel 10.

Each beam receiving groove 12 is implemented with a specific contour, which corresponds to the contour of a specific opening 6 in the beam carrier 5.

As can be seen in FIG. 2, the beam receiving groove 12 has a triangular cross section, wherein one of the top ends of the triangle faces the center of the beam receiving wheel 10. This contour coincides with the contour of the triangular opening 6, which is arranged in the beam carrier 5. This specific opening 6 is indicated by reference numeral 6T in FIG. 1.

The bristle storage container 20 is embodied such that it can accommodate a very large number of individual bristles 22, which are held here between the guide 24, which is schematically shown. In addition to the guide portion 24 illustrated in FIGS. 1 and 2, at least one bottom plate is provided.

The bristle storage container 20 is arranged such that the bristles contained in the bristle storage container are provided to the outer circumference of the beam receiving wheel 10. In particular, the bristles 22 are squeezed slightly against the beam receiving wheel 10.

The beam receiving wheel 10 is rotated with respect to the bristle storage container 20 so that the beam receiving groove 12 is passed over the bristles provided in the bristle storage container 20. Because the bristles are pressed slightly against the bundle receiving wheel 10, a certain amount of bristles 22 enter the bundle receiving groove 12 until the bundle receiving groove is completely filled and forms a bristle bundle. When the beam receiving wheel 10 is further adjusted, it is contained in the beam receiving groove 12 The bristles 22 in the middle are carried to the insertion position in the form of tufts of bristles 14 which are illustrated in FIGS. 1 and 2 and at which the bristle tracts 14 are inserted into the tuft carrier 5 and are particularly inserted Into the opening 6.

An additional guide (not shown here) is provided along the outer circumference of the bundle receiving wheel 10, and the guide prevents the bristle bundle from leaving the bundle accommodation groove 12 in the following cases, that is, when the bristle bundles are removed from the bristles When the storage position on the storage container 20 is adjusted into the insertion position under the insertion device 40.

In order to push the bristle bundles 14 into the corresponding openings 6 of the bundle carrier 5, an insertion device 40 is provided which applies a pushing force or pressure to the bristle bundles in such a way that the bristle bundles face the bundle carrier 5 and are inserted into the corresponding In the opening 6. Referring to FIGS. 1 and 2, the insertion device 40 presses down the bristle bundle 14 as indicated by the arrow.

The bristles are inserted into the bundle carrier 5 at such a speed that the bristles are not displaced laterally, but are inserted straight into the corresponding openings 6 along the longitudinal axis of the bristles.

The insertion device 40 may be implemented as a punch or piston that simultaneously inserts one bristle bundle or a plurality of adjacent bristle bundles from the bundle receiving wheel 10 into the bundle carrier 5 through the introduction aid 30.

To ensure that the tufts of bristles correctly enter the corresponding openings 6 of the tuft carrier 5, the introduction aid 30 is arranged between the “front” end of the tufts 14 and the opposite side of the tuft carrier 5. Here, the introduction aid 30 is implemented as a plate, which is provided with an introduction opening 32. Contour pair Contours of the respective openings 6 of the bristle bundles 14, which are contained in the bundle receiving grooves 12, and the tufts of bristles which are to be inserted therein.

For example, in FIG. 2, the introduction aid 30 has a triangular introduction opening 32 for a triangular bristle bundle 14 provided by the bundle receiving wheel 10 illustrated on the left side in FIG. 1; and a circular introduction opening 32, For a round bristle bundle 14 provided by a bundle receiving wheel 10 illustrated on the right in FIG. 1. Each of the introduction openings 32 is provided with a chamfer 34 on the side facing the beam receiving wheel, so that the insertion of the bristle bundle 14 is simplified.

During operation, the beam carrier 5 is suitably positioned below the beam receiving wheel 10 by means of a holder 50. In this regard, a holder driver, a holder positioning driver, and / or a beam receiver positioning driver described below can be used.

When the tufts of bristles 14 are transported from the bristle storage container 20 to the insertion position above the tuft carrier 5, the insertion device 40 pushes the tufts of bristles 14 through the introduction openings 32 of the introduction aid 30 first, and then into the corresponding openings 6 of the tuft carrier 5. . The bundle carrier 5 can be seen in FIG. 2, which bundle carrier is already provided with bristle bundles 14 with a circular cross section, and this bundle carrier is next to be provided with bristle bundles 14 with a triangular cross section.

During insertion, each tuft of bristles is pushed completely through the introduction aid 30 so that the end of the tuft of bristles 14 that is affected by the insertion device 40 is flush with the side of the tuft carrier 5 facing the tuft receiving wheel 10 to the greatest extent.

Instead of a "straight" introduction opening 32, it is also possible to use an introduction opening that is an introduction opening for deforming and / or turning the tufts of bristles inserted into the introduction opening. Therefore, the bristle bundles can be inserted from, for example, The vertical extension direction is turned to a direction that extends obliquely with respect to the vertical extension direction, so that the bristle bundle can be optimally inserted into the opening 6 extending obliquely in the bristle carrier 5. Alternatively or in addition, the tufts of bristles may be changed from a first cross-sectional shape predetermined by the contour of the beam-receiving groove 12 in the beam receiver 10 to a second cross-sectional shape, for example from circular to angular. In addition, alternatively or additionally, two or more lead-in openings 32 starting separately on the "upper side" of the lead-in aid 30 may meet in a further extension such that the separate beams held on the beam receiver are retained Two or more bundles of bristles in the receiving groove 12 combine into a single bundle, which is then inserted into the opening of the bundle carrier 5.

The introduction opening can also be used to move the bristle bundles laterally, thereby compensating for deviations between the location of the bundle in the bundle receiving groove and the location of the opening in the bundle carrier.

An embodiment of a brush making machine is illustrated in FIG. 3, in which four different beam receiving wheels 10 are illustrated, wherein each beam receiving wheel first forms a plurality of bristle bundles having different profiles, and the plurality of bristles The bundle is then transported from the receiving position to the insertion position.

During operation, the beam receiving wheels 10 are each adjusted in a single direction (counterclockwise in the drawing).

The brush making machine illustrated in FIG. 3 uses a plurality of bristle storage containers 20 that are placed on a bristle container-adjustment drive 26. The bristle container-adjustment drive 26 is implemented similarly to a carousel, with the bristle storage container 20 being adjusted along the beam receiving wheel 10 and also along a filling station 28 on which each of the bristle storage containers 20 is adjusted. The person is provided with new bristles 22. To transport the storage container, a servo drive can be used.

The holder 50 is mounted on a holder driver 52, which is also implemented here in the form of a carousel. In particular, the holder driver 52 may be in particular a holder indexing drive, by means of which the holder 50 (and thus the beam carrier 5 arranged on the holders) are successively of the same size. The step size is adjusted along a single beam receiving wheel 10.

As can be seen by comparing the positions of the beam carriers 5 with respect to the outer circumference of the first, second, third and fourth beam receiving wheels 10, the beam carriers 5 are provided to the beam receiving wheels 10 in different positions.

The beam carrier 5 is provided to the first beam receiving wheel 10 so that the outer circumference of the beam receiving wheel 10 and the outer right edge of the beam carrier "cooperate". In other words: the right outer edge is provided to the beam receiving groove 12 of the beam receiving wheel 10.

The outer circumference of the second beam receiving wheel 10 interacts with the right middle portion of the beam carrier 5.

The outer circumference of the third beam receiving wheel 10 interacts with the left middle portion of the beam carrier 5.

The outer circumference of the fourth beam receiving wheel 10 finally cooperates with the outer left edge of the beam carrier 5.

Different positions of the beam carrier 5 on the respective beam receiving wheels 10 are achieved by a holder positioning driver 54, which is schematically illustrated in detail 3 of FIG. 3. The holder positioning driver 54 acts between the holder driver 52 and the holder 50 and is designed such that The retainer positioning driver can adjust the retainer 50 slightly forward and backward (see arrow P) with respect to a direction in which the retainer 50 is adjusted by the retainer driver 52. Further, the holder positioning driver 54 may be implemented such that the holder positioning driver slightly rotates the holder 50 so that the beam carrier 5 can be provided to the corresponding beam receiving wheel 10 at different angles (see arrow R). It can also be provided that the holder positioning drive 54 adjusts the holder in a direction transverse to the adjustment direction of the holder drive 52.

As an alternative to the holder positioning driver, a beam receiver positioning driver can also be used, by which the position of the beam receiver can be set relative to the holder driver. The beam receiver positioning driver can be implemented, for example, as a moving guide or a slide rail, by which the beam receiver can be appropriately positioned along the adjustment direction of the holder. The insertion device and the lead-in aid can also be placed on the beam receiver positioning drive so that the insertion device and the lead-in aid are adjusted in synchronization with the beam receiver.

Different beam receiving grooves 12 are illustrated in detail in FIG. 4 a, which are arranged on the outer circumference of the first beam receiving wheel 10. It can be seen that a set of beam-receiving openings 12 are provided, the set of beam-receiving openings having different shapes, such as a circular outline, a parallelogram outline, a triangular outline, and a rectangular outline. The bundle receiving grooves 12 form bristle bundles 14 which have the same cross-section or profile as the corresponding bundle receiving grooves 12, and the bristle bundles are further transported such that the bristle bundles are provided to the insertion position to The corresponding bundle carrier 5. Here, the tufts of bristles are inserted into the corresponding openings 6.

As can be seen in FIG. 4 a, the openings 6 in the beam carrier 5 are not precisely aligned with the beam receiving grooves 12 on the outer circumference of the beam receiving wheel 10. Of course, this is not a problem, because the introduction aid 30 is used to appropriately guide the bristle bundles 14 into the corresponding openings 6, and a certain deviation is also compensated here.

The introduction aid 30 is not illustrated in FIG. 4, so that the beam carrier 5 is not affected.

A second beam receiving wheel 10 is illustrated in FIG. 4 b, which is provided on the outer circumference with a set of beam receiving grooves 12, which in this case all have a circular cross section or a circular profile, but have Different diameters. This bundle receiving groove 12 is used to provide six bristle bundles 14 for the six openings 6 in the bundle carrier 5. It can also be seen here that the position of the beam receiving groove 12 need not exactly coincide with the position of the opening 6 in the beam carrier 5.

In FIG. 4c, the beam receiving wheel 10 is provided with another set of beam receiving grooves 12, that is, two beam receiving grooves having a circular outline and one long hole-shaped beam receiving groove arranged between the two beam receiving grooves. 12. It can be seen that the bristle bundles 14 held in the bundle receiving groove 12 are inserted into the corresponding openings 6 in the bundle carrier 5 in the insertion position, wherein the openings are again not perfectly aligned with the bundle receiving grooves 12 of the bundle receiving wheel 10 Oriented together.

The end step of inserting the bristle bundle 14 into the remaining opening of the bundle carrier 5 is illustrated in Fig. 4d, wherein the outline of the bundle receiving groove 12 arranged on the outer circumference of the fourth bundle receiving wheel 10 mirrors the profile arranged on the first A beam receiving groove 12 on the outer circumference of the beam receiving wheel 10.

As can be seen in Figure 4d, the deviation between the two outer parallelogram beam receiving grooves 12 relative to the corresponding openings 6 in the beam carrier 5 is obvious. Nevertheless, the introduction aid 30 enables the tufts of bristles to be properly inserted into the corresponding openings 6 of the tuft carrier 5.

When all of the openings 6 in the bundle carrier 5 are provided with bristle bundles 14, the holder indexing driver 52 transports the bundle carrier 5 to a schematically illustrated final processing station 60 in which the bristle bundles are finally processed. The final processing may consist in cutting the bristles to a desired length and / or orientation. In addition, the bristles can be rounded at the free ends of the bristles.

When pre-rounded bristles are used, the cost for rounding can be reduced, or rounding can be completely eliminated.

It may also be proposed that specific contouring or appearance of the entirety of the bundle is achieved by moving the bristles axially relative to the bundle carrier.

After the bristles are finally processed in the final processing station 60, the holder indexing driver 52 transports the bundle carrier 5 to the welding station 62, in which the ends of the bristles contained in the bundle carrier are heated, so that the material of the bristles Slightly melted. Here, the material constituting the bundle carrier 5 can also be slightly melted. In this case, the bristle materials are connected to one another in a cooperative manner and, if necessary, are connected to the bundle carrier 5 in a solder-like manner.

Basically, the order of the final processing station 60 and the welding station 62 can be reversed, so that the bristles are first fixedly connected to each other and to the beam carrier 5 if necessary, and then finally processed.

An alternative design of the beam receiving wheel 10 is illustrated in FIG. 5. Here, the beam receiving wheel 10 is provided on the outer circumference of the beam receiving wheel 10 The group beam receiving grooves 12, each of which corresponds to a group of beam receiving grooves provided on the four beam receiving wheels 10 of FIGS. 4 a to 4 d.

During operation, each beam receiving wheel 10 is adjusted in steps of 90 °. Each of these positions corresponds to an insertion position of a bristle bundle 14 arranged in a corresponding group of the bundle receiving grooves 12 and a receiving location for a subsequent group of the bundle receiving grooves 12.
