Abstract:
The invention relates to a transfer station ( 1 ) by which bristle filaments, which can be fed to the transfer station in bristle bundles ( 3 ), in which the bristle filaments are assembled in bundle form by at least one band ( 4 ), are transferred to a magazine ( 2 ), in which the bristle filaments are stored. The transfer station according to the invention is characterized in that the transfer station ( 1 ) has at least two pairs ( 8, 9 ) of gripping fingers ( 10, 11; 12, 13 ) spaced apart from one another in the longitudinal direction of the bundles, in that the gripping fingers ( 10, 11; 12, 13 ) of the gripping-finger pairs ( 8, 9 ) can be moved relative to one another, in order to grip a bristle bundle ( 3 ), such that a distance between said gripping fingers ( 10, 11; 12, 13 ) is reduced, and in that the gripping-finger pairs ( 8, 9 ) here grip the bristle bundle ( 3 ) such that at least one band ( 4 ) of the bristle bundle ( 3 ) is arranged between adjacent gripping-finger pairs ( 8, 9 ). The transfer station makes it possible for the bristle filaments fed in bundle form to be transferred in an automated manner to the magazine, which is arranged upstream of a stuffing tool of a brush-production machine (cf. FIG.  1 ).

Description:
BACKGROUND 
       [0001]    The present invention relates to a transfer station for transferring bristle filaments which are infeedable to the transfer station in bristle bundles, said bristle bundles gathering the bristle filaments as a bundle via at least one band, to a magazine, the bristle filaments being stored in said magazine. 
         [0002]    In brush-making machines bristle filaments are inserted into a brush body. The bristle filaments which are inserted into the brush body subsequently form the bristle field of a brush. 
         [0003]    A brush-making machine having a multi-compartment magazine for infeeding bristle bundles from dissimilar bristle reserves to a bundle separator for a stuffing tool is known from DE 197 45 024 A1, the bundle separator having a separator notch. The multi-compartment magazine has a plurality of infeeding ducts which may be filled with the aid of a loading installation for bristle material. The loading installation has a storage magazine which has a number of obliquely disposed receptacle compartments for in each case a plurality of bristle bundles, said number corresponding to the number of magazine infeeding ducts. Here, the individual bristle bundles are sheathed with a covering, for example of paper, which prior to the bristle material being infed to the infeeding ducts is removed in that gripping pliers retrieve the bristle material from the covering. The uncovered bristle material may then be taken over to the uncovering station by an infeeding gripper and deposited into one of the infeeding ducts. 
         [0004]    A further brush-making machine having a stuffing installation which has a bundle separator having a separator notch has been previously known from DE 101 60 220 A1. The bundle separator is assigned a multi-compartment magazine having a plurality of infeeding ducts for bristles. A storage installation for bristles is provided so as to be spatially removed from the multi-compartment magazine. Here, an intermediate conveying installation having a gripper serves for the removal of bristles from the storage installation and for the transfer thereof into one of the infeeding ducts of the multi-compartment magazine. 
         [0005]    In the case of these two brush-making machines which per se have been successful, the bristle material with the aid of the loading installation or with the aid of the intermediate conveying installation, respectively, may be removed from the bristle reserve and transferred to the magazine in an automated manner, since the bristle material which is processed on these brush-making machines is composed of bristle filaments which across their entire length are cylindrically configured. 
         [0006]    Chemically tapered bristle filaments which are also referred to as “tapered filaments” have already been created. These tapered bristle filaments which taper off in a wafer-thin bristle tip are increasingly used on a world-wide scale in order for particularly soft toothbrushes to be achieved therewith. Since these bristle filaments are particularly thin, such tapered bristle filaments are to this day still manually placed into the magazine of a brush-making machine. Such a magazine which is also referred to as a material hopper has at least one conveying track which on both sides is delimited by a side strip and which is disposed upstream of a stuffing tool of the brush-making machine. 
         [0007]    The chemically tapered bristle elements are typically offered in bristle bundles which are mostly consolidated so as to be of a round cross section. The bristle filaments of a bristle bundle here are held together by at least one band and preferably by at least one rubber band. During manual placing of the bristle filaments which are still held together as a bundle the bristle bundle is put on the base plate of the magazine and subsequently indexed between the side strips of a conveying track which is provided in the magazine up to pushers which are displaceable on both sides of the side strips. Thereafter, the rubber bands which still hold the bristle bundles together are removed, so as to draw the pushers via pressure onto a sensor behind the bristle filaments which are now no longer in a bundle, so that the pushers can press the fresh bristle material against the bristle filaments which are already located in the conveying track. Since the tapered bristle filaments must always be well encompassed, it often arises that the pusher which laterally projects beyond the side strips also pushes onto the fingers. Since the pressure acting on the pusher is not very high, only slight pressure points arise. Since the brush-making machine during the placing phase of the bristle bundles should not be stopped, the magazine moves when switching over from one bristle color to another bristle color has to take place. Due to this, serious pinching may arise, also due to lack of attention of the operator. Such pinching and the injuries to the operator related thereto must, however, be positively avoided. 
       SUMMARY 
       [0008]    There is, therefore, in particular the object of achieving a transfer station of the type mentioned at the outset which permits automated transferring of the bristle filaments which are supplied as a bundle to the magazine which is disposed upstream of the stuffing tool of a brush-making machine, for example. 
         [0009]    The solution according to the invention in the transfer station of the type mentioned at the outset particularly lies therein that the transfer station has at least two pairs of gripper fingers which are spaced apart from one another in the longitudinal direction of the bundle, in that the gripper fingers of the gripper finger pairs for gripping a bristle bundle are movable transversely to the longitudinal direction of the bundle in relation to one another in such a manner that the spacing of these gripper fingers is reduced, and in that the gripper finger pairs here grip the bristle bundle in such a manner that at least one band of the bristle bundle is disposed between adjacent gripper finger pairs. 
         [0010]    The transfer station according to the invention is intended for transferring bristle filaments to a magazine, said bristle filaments being infed to the transfer station as bristle bundles. Here, the bristle filaments of a bristle bundle are typically grouped together via at least one band. The bristle filaments are subsequently stored in a non-bundled manner in the magazine. The transfer station according to the invention has at least two pairs of gripper fingers, said gripper finger pairs being mutually spaced apart in the longitudinal direction of the bundle. The gripper fingers of the gripper finger pairs are movable in relation to one another in such a manner that the spacing of these gripper fingers may be reduced in order for the bristle filaments to be loosely clamped or held, respectively, between the gripper fingers of each of the gripper finger pairs. The provided bristle bundle here is acquired in such a manner that at least one band of the bristle bundle is disposed between adjacent gripper finger pairs. The transfer station according to the invention has at least one band opener which is intended for opening the at least one band of a bristle bundle acquired by the gripper finger pairs. The gripper finger pairs which are mutually spaced apart in the longitudinal extent of the bristles permit the bristle filaments which are delivered in bundles to be unwrapped, due to which automated transferring of the bristle filaments to a magazine which subsequently stores the bristle filaments in a non-bundled manner is enabled. 
         [0011]    In order for a bristle bundle which is held between the gripper finger pairs to be released from the at least one band enclosing the bristle bundle, it is advantageous for the transfer station to have at least one band opener for opening the at least one band of a bristle bundle acquired by the gripper finger pairs. 
         [0012]    Here, preferred embodiments according to the invention provide that the at least one band opener is configured as a knife, as scissors, or as pliers. 
         [0013]    In order for the band which has been opened in this manner to be able to be removed from the region of the bristle filaments, it is advantageous for the at least one band opener to be assigned a band gripper which acquires the band to be opened by the band opener. After the band has been opened by the band opener the band gripper may move the band laterally past the bristle filaments and remove said band. 
         [0014]    Instead of such a band gripper, another advantageous embodiment according to the invention provides that the at least one band opener is assigned a suction installation which suctions the band opened by the band opener and conveys said band away by a suction flow. 
         [0015]    In order to not cause an obstruction when the band is opened with the aid of the band opener, it is expedient for the band gripper or the suction installation to be disposed on the side of a bristle bundle that faces away from a band opener. 
         [0016]    It is possible for the gripper finger pairs of the transfer station to grip the respective bristle bundle in a position in which the bristle filaments by way of their longitudinal extent are oriented approximately in the horizontal direction. However, an embodiment in which the gripper finger pairs grip the respective bristle bundle in a position in which the longitudinal direction of the bristles is oriented approximately in the vertical direction is preferred. 
         [0017]    Since individual bristle filaments may fall out and go astray even from the bristle bundle which is encompassed by at least one band, it is advantageous for the bristle bundles in the region of the gripper finger pairs to be disposed so as to have the one bundle end side thereof on a supporting element. It is ensured in this way that not even a single bristle filament of a bristle bundle which is held by the gripper finger pairs may fall down and go astray. 
         [0018]    In order for the bristle bundles in the region of the gripper finger pairs to be moved and for the bristle bundles to be infed to the transfer station, it is advantageous for the supporting element to be configured as a conveyor belt, said conveyor belt infeeding the bristle bundles to the gripper finger pairs. 
         [0019]    In order for the bristle filaments which are still being held between the gripper finger pairs and are optionally already relieved from the at least one band to be able to be conveyed and moved in the direction of the magazine, it may be advantageous for the bristle bundles located on the supporting element on that end side thereof that faces away from the supporting element to be acquirable by a suction plate. 
         [0020]    Here, one preferred embodiment according to the invention provides that the suction plate has a Dutch-weave fabric which is perfusable by the suction flow of a suction blower. Such a Dutch-weave fabric has a structure which is fine in such a manner that the bristle filaments are indeed not sucked through the Dutch-weave fabric but instead in the suction flow of the suction blower are caught in the Dutch-weave fabric. This suction flow may pass through the Dutch-weave fabric by way of the openings which are formed by the woven-fabric structure. 
         [0021]    In order for the bristle bundles to be able to be de-bundled in an orderly manner and the bristle filaments which are as yet still infed as a bundle to be able to be handed over to the magazine, it is advantageous for the bristle bundles on the supporting element which is configured as a conveyor belt to be kept so as to be spaced apart, and to this end for at least one bristle bundle stopper which is displaceable or pivotable between a standby position and a holding position projecting into the conveying path of the conveyor belt to be provided. This at least one bristle bundle stopper which in terms of control is linked to at least one light barrier or a similar optical bristle-bundle detector is capable of extending the spacing between the bristle bundles located on the supporting element to the desired spacing. In order to be able to hand over the bristle filaments which have been relieved from the at least one band to the magazine, it is expedient for a further gripper finger pair which takes over the bristle filaments to be interjectable into the intermediate space which is disposed between gripper finger pairs which are spaced apart in the longitudinal direction of the bundle. While the bristle filaments which have been relieved in this manner from the band stick to the suction plate, the bristle filaments adhering to the suction plate are held together by the at least one further gripper finger pair which is interjectable into the intermediate space of the gripper finger pairs described above, which are spaced apart in the longitudinal direction of the bundle. 
         [0022]    In order to impart a certain external contour to the bristle filaments which are held together by at least one band and indeed to the bristle filaments which have been relieved of the at least one band, said external contour facilitating handling of these bristle filaments, it is advantageous for on at least one gripper finger of at least one gripper finger pair at least one longitudinal delimitation which projects beyond the gripper finger so as to be lateral to the adjacent gripper finger of the gripper finger pair to be provided. 
         [0023]    Here, one preferred embodiment according to the invention provides that at least one longitudinal delimitation is held so as to be adjustable on the gripper finger. 
         [0024]    In order for the bristle filaments which have been de-bundled in the transfer station to be able to be infed to the magazine and subsequently to be stored in the magazine, it is advantageous for the magazine to have at least one conveying track in which the bristle filaments which are oriented in the vertical direction are disposed between two side strips. 
         [0025]    Threading of the bristle filaments into the conveying track which is delimited by two side strips is facilitated when the at least one conveying track has an introduction region in which the spacing of the side strips which delimit the conveying track is reduced in the conveying direction. 
         [0026]    In order for the bristle filaments which are stored in a conveying track to be held and secured in their position which is oriented in the vertical direction, it is expedient for the bristle filaments which are located in the at least one conveying track to be held by at least one pusher which laterally projects beyond a side strip and is preferably displaceable along this side strip. 
         [0027]    Here, handling of the de-bundled bristle filaments in the region of the at least one conveying track is further facilitated when a laterally projecting pusher is provided on each side strip. 
         [0028]    In order for the bristle filaments to be able to be indexed in the conveying track and to be moved in the direction of a stuffing tool, for example, it is advantageous for each conveying track to be assigned a slider which is displaceable between the side strips of this conveying track. 
         [0029]    Handling of the bristle filaments which are oriented in the vertical direction is facilitated and secured also in the region of the conveying track of the magazine when at least one slider has at least two slider fingers which are mutually spaced apart in such a manner that the at least two slider fingers are placeable so as to bear on the bristle filaments and to be spaced apart in the longitudinal direction of the latter. In this embodiment the slider has at least two slider fingers which in the longitudinal extent of the bristles engage on the adjacent bristle filaments so as to be mutually spaced apart. 
         [0030]    Additionally or alternatively to the already mentioned supporting element, it may be expedient for the transfer station to have at least one supporting element which is preferably configured as a conveyor belt for providing and/or infeeding bristle filaments which are held together as bristle bundles by at least one band and/or by a sheathing, wherein the at least one supporting element may be assigned at least one gripper installation having at least one holding and retrieval gripper and at least one removal gripper. The at least one gripper installation having the at least one holding and retrieval gripper may be specified for acquiring a bristle bundle, which is provided on this supporting element and/or an infed bristle bundle, and for at least partially retrieving the band and/or the sheathing, and the at least one removal gripper may be specified for acquiring a bundle portion which is relieved from the at least one band and/or the sheathing and for removing and conveying the bristle bundle onward. Onward conveying of the bristle bundle which has been relieved of the band and/or of the sheathing may then be performed to a, for example the already mentioned, magazine, or also directly to a brush-making machine which is disposed downstream of the transfer station, in particular to a stuffing tool of a brush-making machine. 
         [0031]    One particularly advantageous embodiment according to the invention provides that the transfer station is disposed so as to be upstream of the stuffing tool of a brush-making machine. 
         [0032]    Refinements according to the invention are derived from the claims in conjunction with the description of the figures and the drawings. The invention will be explained in yet more detail hereunder with reference to a preferred exemplary embodiment.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0050]    The details of a transfer station  1  which is intended for transferring bristle filaments which are infed as a bundle to a magazine  2  which subsequently stores the bristle filaments in a de-bundled manner are illustrated in  FIGS. 1 to 15 . Such bristle filaments are typically offered as bristle bundles  3  in which the bristle bundles are held together by at least one band and in particular by at least one rubber band  4 . For example, the magazine  2  may be disposed upstream of a stuffing tool  5  of a brush-making machine, said stuffing tool  5  removing a part-quantity of bristle filaments from the reserve which is located in the magazine  2 , so as to subsequently insert the bristle filaments into a brush body  6  which is provided in the brush-making machine. To this end, the brush body  6  by means of a positioning device  7  is positioned ahead of the stuffing tool  5 . 
         [0051]    It can be seen in  FIGS. 1, 2, and 5 to 8  that the transfer station  1  has at least two pairs  8 ,  9  of gripper fingers  10 ,  11 ;  12 ,  13  which are mutually spaced apart in the longitudinal direction of the bristle bundles. In order to grip an infed bristle bundle  3 , the gripper fingers  10 ,  11 ;  12 ,  13  of the gripper finger pairs  8 ,  9  here are movable in relation to one another in a transverse manner to the longitudinal direction of the bundle in such a manner that the mutual spacing of the gripper fingers  10 ,  11 ;  12 ,  13  is reduced. If the spacing of the gripper fingers  10 ,  11 ;  12 ,  13  of each of the gripper finger pairs  8 ,  9  is reduced, the bristle bundle  3  is deformed from the original shape which is round in cross section and is depicted on the left side in  FIG. 10  into the shape which is shown on the right side in  FIG. 10  and is now elongate. The gripper finger pairs  8 ,  9  here grip the bristle bundle  3  in such a manner that the rubber band  4  which still holds the bristle filaments together and which in cross section is preferably out-of-the-round and preferably approximately rectangular is located between the gripper fingers  10 ,  11 ;  12 ,  13  of adjacent gripper finger pairs. 
         [0052]    It can be seen in  FIG. 2  that the bristle bundles  3  by way of their one bundle end side are placed on a supporting element which here is configured as a conveyor belt  14 . The bristle bundles  3  are infed on the conveyor belt  14  to the transfer station  1 . In order for the bristle bundles  3  to be able to be released and conveyed onward in an orderly manner, the bristle bundles  3  are set so as to be spaced apart on the conveyor belt  14 . To this end, at least one bristle bundle stopper  15 ,  16  which is displaceable or pivotable between a standby position and a holding position which projects into the conveying path of the conveyor belt  14  is provided. The pairs of bristle bundle stoppers  15 ,  16  which in each case in terms of control are connected to a light barrier and here are disposed on both sides of the conveyor belt  14  make sure that the bristle bundles  3  are kept so as to be spaced apart. The bristle bundles  3  on the conveyor belt  14  are infed to the two gripper finger pairs  8 ,  9 , said gripper finger pairs being mutually spaced apart in the longitudinal direction of the bundle. The gripper fingers  10 ,  11 ;  12 ,  13  of the gripper finger pairs  8 ,  9  are mutually displaceable or movable in relation to one another in a transverse manner to the longitudinal direction of the bundle such that the spacing of these gripper fingers  10 ,  11 ;  12 ,  13  is reduced and a bristle bundle which is located between the gripper fingers  10 ,  11 ;  12 ,  13  of the gripper finger pairs  8 ,  9  is securely held. Here the gripper finger pairs  8 ,  9  grip the bristle bundle  3  in such a manner that the at least one rubber band  4  which holds together the bristle filaments of a bristle bundle  3  is disposed between adjacent gripper finger pairs  8 ,  9 . 
         [0053]    It is indicated in  FIG. 2  that the transfer station has at least one band opener  17  which here is designed as scissors. The band opener  17  is provided for opening the at least one rubber band  4  which surrounds the bristle bundle which is being gripped by the gripper finger pairs  8 ,  9 . While the band opener  17  which is configured as scissors severs the at least one rubber band  4 , the rubber band  4  on that side of the bristle bundle  3  that faces away from the band opener  17  is held by a pliers-type band gripper  18  which subsequently pulls and conveys away the cut-open rubber band  4  past the bristle bundle. The rubber band  4  is subsequently dropped into a waste container. Instead of the band gripper  18 , direct suctioning of the cut-open rubber band  4  may also be provided. In the case of the band opener  17  and of the band gripper  18  a circular filament displacement element  19  which makes sure that individual bristle filaments are not severed in addition to the rubber band  4  or jammed is provided at the tip of the scissor arms or pliers arms, respectively. 
         [0054]    In  FIG. 3  the bristle bundle  3  is deformed in a subsequent method step. When the gripper fingers  10 ,  11 ;  12 ,  13  converge, the bristle bundle  3  which in cross section is initially still round is deformed in such a manner that in terms of its cross section it assumes the elongate shape which is shown in  FIG. 10 . Prior to this deformation taking place, a cover plate  20  is pivoted or moved in such a manner that the latter is held over the bristle bundle  3 , so as to prevent even a single bristle filament escaping. The deformation of the bristle filaments which are still held together as a bundle by the gripper finger pairs  10 ,  11 ;  12 ,  13  is performed by the two gripper finger pairs  8 ,  9 . 
         [0055]    It is indicated in  FIG. 4  that a further gripper finger pair  21  having gripper fingers  22 ,  23 , which takes over the bristle filaments which are now no longer held by a rubber band  4 , is interjectable into the intermediate space which is provided in the longitudinal direction of the bundle between the gripper finger pairs  8 ,  9 . At the same time a suction plate  24 , which by way of a suction flow holds the bristle filaments at the ends thereof, is moved over that end side of the bristle filaments that faces away from the supporting element. This suction plate  24  has a Dutch-weave fabric which is fine in such a manner that the bristle filaments cannot be suctioned through the suction plate. 
         [0056]    In  FIG. 5  the gripper finger pair  21  and the suction plate  24  have removed the bristle filaments which have been relieved of the rubber band from the infeed which is formed by the conveyor belt  14  and by the gripper finger pairs  8 ,  9 , so as to now move these bristle filaments to the magazine. In  FIG. 7  the construction of a gripper finger pair is shown in detail by the gripper finger pairs  8 ,  9 . As can be seen, a longitudinal delimitation  25  which in each case laterally projects over the gripper finger toward the adjacent gripper finger of the gripper finger pair  8  or  9  is provided on each gripper finger on both sides of the bristle filaments. This longitudinal delimitation which is held so as to be displaceable or adjustable on the gripper finger assigned to the former, in relation to the gripper finger that supports the longitudinal delimitation  25  has an obtuse angle, for example an angle of 100 degrees. Light barriers  26  which signal the presence of the bristle filaments are also provided in the region of the gripper finger pairs  8 ,  9 . 
         [0057]    The gripper finger pair  21  and the suction plate  24  subsequently move the bristle filaments to the magazine  2  shown in  FIGS. 1 to 15 . The magazine  2  has at least one conveying track  27 , the bristle filaments which have been relieved of the bands  4  being stored in said conveying track  27 . The conveying track  27  has two side strips  28 ,  29  which are mutually spaced apart and which guide the bristle filaments which are oriented in the longitudinal direction of the bristles. 
         [0058]    The conveying track  27  has an introduction region  30  in which the spacing of the side strips  28 ,  29  which delimit the conveying track  27  is reduced in the conveying direction. In  FIGS. 11 and 13  the bristle filaments which are held on the gripper finger pair  21  and on the suction plate  24  in the introduction region  30  between the two side strips  28 ,  29  are pushed into the conveying track  27 . Direct placing from above between the side strips  28 ,  29  is also possible if and when the spacing between the side strips  28 ,  29  is larger than the cross section of the bristle filaments which are held together in an elongate shape. 
         [0059]    In the conveying track  27  the bristle filaments are held by way of at least one pusher which laterally projects beyond a side strip  28 ,  29  and is displaceable along these side strips  28 ,  29 . It can be seen in  FIGS. 11 and 13  that the side strip  28  has two pusher ducts  31  in which in each case one pusher  32  is displaceable, and that the pushers  32  which are displaceable on the side strip  28  and pivotable into a holding position in the conveying track  27  are mutually spaced apart in the longitudinal direction of the bristles. 
         [0060]    The conveying track  27  is also assigned a slider  33  which is displaceable between the side strips  28 ,  29  of the conveying track  27  and compresses the bristle filaments which are stored there. This slider  33  here has at least two slider fingers  34 ,  35  which are mutually spaced apart in the longitudinal direction of the bristles and which in the side strips  28 ,  29  are guided in slider ducts  36 . The slider ducts  36  in the introduction region  30  are configured so as to be funnel-shaped, so as to be able to acquire and receive the slider fingers  34 ,  35 . 
         [0061]    The bristle filaments which in  FIG. 14  are situated in the conveying track  27  there are lowered up to a base plate of the conveying track  27  and pushed against the pushers  32 . In order to ensure secure holding of the bristle filaments here, the pusher  33  is placed to bear on the bristle pack from behind. The gripper finger pair  21  may subsequently be removed, such that the slider  33  now presses the bristle pack against the two pushers  32 . The two pushers are laterally removed, so as to be able to again be pivoted parallel with the slider  33  into their holding position behind the newly infed bristle pack, the entire bristle reserve now being held together by the pushers  32  in said holding position. 
         [0062]    The gripper finger pair  21  and the suction plate  24  have been removed from the region of the bristle filaments in  FIG. 15 . It is indicated in  FIGS. 11 and 13 to 15  that a contact element  37  is assigned to the conveying track  27 . This contact element  37  in the longitudinal direction of the bristles is movable by a few millimeters between an upper and a lower contact element position, the bristle filaments being impinged in the lower contact element position at the free bristle ends of said bristle filaments. Impinging the bristle filaments stored in the conveying track  27  is intended to prevent that individual bristle filaments move upward while being moved onward in the conveying track  27 . In order for a protrusion of this type of individual bristle filaments to be effectively prevented it is advantageous for the contact element  37  to extend across the entire region of the bristle material which is stored in the conveying track  27 . 
         [0063]    In one embodiment of the transfer station  1 , which is not illustrated in the figures, said transfer station  1  is provided with at least one further supporting element which is preferably configured as a conveyor belt for providing and/or infeeding bristle filaments which are held together as bristle bundles  3  by at least one band and/or by a sheathing. This at least one further supporting element is assigned a gripper installation having at least one holding and retrieval gripper and at least one removal gripper. The gripper installation having the at least one holding and retrieval gripper is specified for acquiring a bristle bundle  3  which is provided and/or infed on the supporting element assigned thereto and is covered with at least one band and/or a sheathing, and for at least partially retrieving the band and/or the sheathing. By way of the at least one removal gripper a bundle portion of the bristle bundle  3 , which has been relieved of the at least one band and/or of the sheathing may be gripped and the bristle bundle  3  in this way be removed from the supporting element and conveyed onward. Onward conveying of the bristle bundle  3  is then performed, for example, to the magazine  2  and/or to a brush-making machine which is disposed downstream, in particular directly to a stuffing tool of such a brush-making machine. 
         [0064]    The transfer station  1  illustrated here permits automated transfer of bristle filaments which have been infed as a bundle to the magazine which is disposed upstream of the stuffing tool of a brush-making machine. Since this transfer no longer has to be performed manually, unintentional pinching of and injury to the operator are prevented. The transfer station  1  shown here is particularly well suited to operation in conjunction with such bristle filaments which are processed, treated and/or marked on at least one bristle end. The transfer station  1  illustrated here in this way may be advantageously used with bristle filaments which are chemically or mechanically tapered on at least one bristle end. Such bristle filaments can have unilateral chemically tapered ends, bilateral chemically tapered ends, or unilateral or bilateral bristle ends which have been mechanically tapered. The transfer station may also be used in conjunction with such bristle filaments which have pre-rounded or spliced bristle ends. The transfer station  1  may also be used with such bristle filaments which on at least one bristle end are colored, preferably by way of a marker.
