Definitions
- the brush filling device The brush filling device
- the invention relates to a Bürstenstopfvorraum for stuffing and fixing bristle tufts in a brush body.
- the classic method is to fold an isolated bristle tufts in half and to fix it in the middle via a metal plate, called anchor, or a loop (usually a wire loop) in the opening in the brush body.
- the anchor then pushes or cuts into the wall of the opening, a loop typically in the bottom of the opening.
- the brush darning device comprises a tuft singler which removes bristles from a bristle magazine in which large amounts of bristles lie next to one another and thereby separates them into tufts.
- This singulation is accomplished by having the tuft singler on its outer periphery one or more receiving recesses which line the edge of the bristle magazine so that bristles are forced into the receiving recess to form a tuft. This tuft is then moved out of the area of the magazine, where it is taken over by a stuffing tool. The tamping tool moves the tuft along a straight path directly to the brush body, folds it in advance, and abuts it with the bent end of the tuft together with the anchor or loop.
- bristle tufts are either stuffed directly into the brush body or stuffed into an intermediate container and then pushed into the brush body or encapsulated end side to form the brush body.
- the attachment of the Bostenbüschel on prefabricated brush body is done for example by gluing, heating, welding and / or encapsulation.
- a tuft singler so far mainly circular arc segment parts or discs are used, each having on their outer circumference, the receiving recesses.
- Circular arc segments are a kind of pivoting lever, which are pivotable about an axis of rotation and at its the outer axis of the rotation axis remote outer circumference have a circular arc segment shape whose center is the axis of rotation.
- the circular arc segment is reversed, ie pivoted back and forth, between a separating position in which the receiving recess in the region of the magazine, and a transfer position, in which the preferably linearly movable stuffing tool takes over the scattered tuft.
- These circular arc segment-like tuft singles usually only take one tuft per stroke.
- tuft singlers which have a plurality of receiving recesses on their outer circumference and which are rotated only in one direction of rotation, i. do not drive in reversing mode. These tuft singles are always indexed step by step and immediately connect to the stuffing tool, which takes over the isolated tufts one after the other.
- Object of the present invention is to provide a stuffing tool with anchor technology, in which the clock rate is increased and the stuffing quality is improved.
- the Bürstenstopfvoroplasty invention for stuffing and fixing bristle tufts in a brush body comprises a tuft singler, which removes bristle tufts from a bristle magazine and at its outer periphery at least one receiving recess for bristle tufts, which are transported by rotating the tufts singulator along a circular segment or a circular path.
- the brushing device comprises a stuffing tool which moves tufts along a preferably rectilinear path, abuts an opening in the brush body and anchors the bristle tufts therein or abuts an opening in the tundish.
- a movable takeover tool is provided, the tuft takes the tuft singler and transferred to the tamping tool, wherein the takeover tool axially on opposite sides of the tuft singler each having at least one holding unit, and wherein the at least two holding units together hold the bristle tufts to be removed and moved to the tamping tool.
- the invention provides that the movable stuffing tool does not itself, as was customary in the prior art, the isolated bristle tufts the tuft singles removes, but that here a takeover tool is interposed. Through this takeover tool, it is possible to grab the bristle tufts and hold them until the tamping tool has actually taken over the tuft safely. In previous Stopfvorraumen there was the problem in the transfer of bristle tufts from the separator to the stuffing device that occasionally bristles are slipped in the acquisition by the stuffing tool, so that they protrude in the finished brush against the exactly aligned bristles. This leads to rework or rejects.
- the transfer tool can be reciprocated along a circular arc segment path between a receiving and dispensing position or along a linear path.
- the transfer tool comprises at least one movable, in particular movable back and forth tuft picker and a counterpart.
- This counterpart may preferably be stationary, ie not movable.
- the tuft picker moves the bristle tufts along the edge of the counterpart (holder between counterpart tuft picker) and the tamping tool.
- a variant provides that the tuft picker has a plate shape. This plate has at the same time a circular arc section, with which it moves along the complementary counterpart.
- the tuft taker can in particular have a marginal arcuate section with at least one laterally open receiving opening for the isolated bristle tuft to be transported.
- the tuft picker is so pivoted
- the tuft picker can be pivoted back and forth on a circular path.
- the counterpart has a circular path complementary to the concave arc edge, which prevents slipping out of the tuft from the receiving opening.
- the counterpart can therefore be seen in the axial direction (longitudinal direction of the tuft) closing the laterally open receiving opening during the process of tufts of bristles, so that the isolated bristle tufts is held.
- the counterpart can be axially at the height of the tuft picker, but also axially offset to him.
- the holding unit may comprise a movable part along a circular path, in particular an arm which has a slot open laterally to the counterpart, which forms the receiving opening.
- the movable part is adjustable in the lateral direction, towards the counterpart. About this evoked movement to the counterpart takes the part in a transfer point the bristle tufts laterally in the slot.
- the transfer tool has a common or in each case a tuft picker for the parts movable along a circular path, which form the holding units.
- the transfer tool has according to a variant at least or exactly one tuft picker and additionally the two along a circular path movable parts. These movable parts lie in the transport direction of the isolated bristle tufts after the tuft picker and take isolated bristle tufts from the tuft pickup, then to the To bring stuffing tool. At the transfer point, the parts are then moved laterally to pass on the bristle tufts.
- a variant of the invention provides that the stationary counterpart is provided both for the tuft picker and for the movable part, so that the common counterpart laterally closes the receiving opening of the tuft picker and the movable part.
- the counterpart has a concave edge with two arc sections, which are connected to each other via a radial shoulder.
- the transfer point from the tuft picker to the movable part is then the transfer point from the tuft picker to the movable part.
- the tuft is moved radially outward on the heel, it is simultaneously pushed out of the receptacle in the tuft picker.
- the movable part then takes over the holder of the bristle tufts.
- the transfer tool can have at least one clamping unit, which transports the bristle tufts in a clamping manner from the tuft singler to the tamping tool.
- this clamping unit or the plurality of small units can be constructed.
- An embodiment of the invention provides that at least one
- Clamping unit or a plurality of clamping units axially offset from the tuft singler capture the bristle tufts to be removed.
- At least one clamping unit can be provided axially on opposite sides of the tuft singler, which grip the bristle tufts to be removed by clamping.
- the several clamping unit which attack on both sides of the tuft singler on bristle tufts, the bristle tufts is held more secure during transport.
- the detached bristle tufts between the tuft picker and the counterpart or, in general, already clamped in the clamping unit in some way it may be advantageous to provide at least one movable clamping finger.
- This clamping finger clamps the removed bristle tufts and secures it during transport.
- the clamping finger can be installed in the tuft picker.
- clamping fingers may be plate-shaped, which is not to be understood as limiting.
- the clamping finger is received in a recess in the tuft picker. If the tuft picker is plate-shaped, then the plate is laterally, i. Provided frontally open recess in which the clamping finger is located. The clamping finger protrudes, optionally, into the receiving opening in the tuft picker.
- the clamping finger can also serve to reduce the already existing receiving opening in the tuft picker in cross section, with a view of the receiving opening in the axial direction. Then, the clamping finger protrudes at least in its closed position into the receiving opening (seen in the axial direction) and reduces the cross section of the receiving opening.
- Another variant provides to form the clamping unit by a pair of pliers.
- a pair of pliers For secure holding of the bristle tufts, at least one pair of pliers is provided on the transfer tool, which still clamps the bristle tufts in the receiving recess and moves in a clamping manner to the stuffing tool.
- the at least one pair of pliers can grasp the bristle tufts, in particular offset axially from the tuft singler, wherein they preferably adjoin the tuft singler, ie the disk or the circular arc, axially directly.
- An embodiment of the invention provides that in each case at least one pair of pliers is provided axially on opposite sides of the tuft singler, which grip the bristle tufts in a clamping manner.
- each bristle tuft is detected with two pliers, which preferably clamp synchronously, are loosened and moved. These two pliers can eg be directly adjacent to the tuft singler.
- the subsequent stuffing tool then grasps the bristle tufts between the tongs, so that they are finally held perfectly aligned in the tamping tool.
- the at least one pliers can sit on a swivel arm or form part of it. For clamping itself, preferably only one arm of the forceps is moved while the other remains stationary.
- the at least one pair of pliers can be e.g. in that it has two axially bent fingers, between which the tufts are clamped. This makes it possible to position the associated pivot arm slightly farther from the tuft singulator and from the tamping tool so as not to create space problems in these areas.
- the tuft singler can only be rotated in one direction of rotation and is here e.g. be designed as a disc, wherein the receiving recesses circulate on a circular path.
- the tuft singler has a circular arc segment on the outer circumference and is pivoted back and forth.
- a tuft singler with a disk or a cylinder which rotates in only one direction, with respect to the clock rate of advantage, because by further indexing in one direction eliminates the return stroke that occurs in a circular arc segment-like tuft singler. This also gives more time to grab the tufts exactly and pass them on.
- the invention provides in a further improvement that a centering unit is provided which axially aligns the tuft taken out of the tuft singulator. This is to avoid that individual bristles protrude from the rest of the tuft.
- a centering unit is provided which axially aligns the tuft taken out of the tuft singulator. This is to avoid that individual bristles protrude from the rest of the tuft.
- brushes that have bristles of different lengths. These brushes are made by providing a plurality of bristle magazines containing bristles of different lengths. The tuft singler then removes a tuft from the bristle magazine, which due to its length is to be stuffed next.
- FIG. 9 shows diagrammatically a corresponding situation in the case of three juxtaposed bristle magazines 26, 26 ', 26 "with bristles of different lengths., 100, 102 and 104 denote the axially differently oriented bottoms of the bristle magazines 26, 26', 26".
- the median plane 106 indicated by a dot-dash line is the axial center plane of the tuft singler, that is to say a circular arc segment or a disc, as well as the stop plane.
- the support surface may be axially adjusted to adjust its height to the length of the bristles being processed and to align the tufts in their longitudinal direction with the stuffing tool.
- This adjustable abutment surface may also be used to evenly displace all the bristles of a tuft. by the support surface optionally axially repeatedly tapping against the tuft.
- Another way of axial tuft adjustment and its axial alignment is to provide the axial centering unit with an axial drive to axially at least that portion of the transfer tool that clamps the bristle tufts, and axially align the clamped bristle tufts depending on its length.
- the centering unit moves the bristle tufts in the movement phase between the transfer position on the tuft singler and the delivery position on the tufting tool in the axial direction, so that an adjustable with the high clock rates support surface is no longer necessary.
- the axial drive of the centering unit also makes it possible to have the bottoms of the bristle magazines on the same plane. This at least opens the theoretical possibility to work with the same axial bearing surface, if this is necessary at all.
- the removed tufts of bristles be aligned axially so that their axial center lies exactly in the stop plane.
- the bristle tufts are not folded centrally at the stopper but off-center to produce two different length bristle tuft halves.
- the axial drive of the centering unit can be controlled so that it moves before assumption or after taking over the respective bristle tufts from the tuft singler at least that portion of the takeover tool that clamps the bristle tufts in the axially aligned position in which the bristle tufts is taken over by the tamping tool. If a bearing surface is to be provided, the axial alignment can also take place as late as possible, for example only immediately before transfer to the stuffing tool.
- the entire transfer tool for example, including its drives, are axially moved by the axial drive of the centering unit in order to simplify the overall construction.
- both tongs can be moved together in the same axial direction, or one of the tongs can only be moved axially, for example the upper tongs, if the bottoms of the bristle tins are in the same plane lie.
- the lower pliers must be open in this case.
- the stuffing tool has e.g. a linear guide, along which the tufts are moved and stuffed, and a movable tongue which pushes the tuft to be stuffed with folding the bristle tuft together with an anchor or a loop in the opening.
- the tuft to be stuffed is moved by the tongue in the folded state.
- the tongue clamps the bristle tufts and only then the takeover tool is opened and releases the tuft. This prevents individual bristles from partially slipping out of the tuft during transfer.
- the bristle tufts are first clamped in the tuft singler and then removed, wherein the clamping can also take place during or after removal, when the tuft is still guided axially.

- FIG. 8 a prior art brush plugger is shown having a tuft singler 10 and a stuffing tool 12 immediately adjacent thereto.
- the tuft singler 10 is in this case a reciprocally pivotable crescent-shaped element 14, which has on its outer circumference 16 a circular arc segment shape with center on the pivot axis of the tufts singler 10.
- a receiving recess 18 in the element 14 is formed, which is adapted to receive a single bristle tufts 20 is dimensioned.
- a guide 22 abuts the element 14 and has a concave surface 24 adapted to the outer circumference 16 along which the element 14 travels as it moves towards the stuffing tool 12 and prevents bristle tufts from falling out of the receiving recess 18.
- a bristle magazine 26 also adjoins the outer periphery 16 and has bristles parallel to one another. The magazine is biased to push bristles against the outer periphery 16.
- the tamping tool 12 has a linear guide 28 along which bristle tufts are transported to a brush body 30 or intermediate container 31 having prefabricated openings into which bristle tufts are stuffed.
- the brush body may either be the complete, non-brushed part of a brush, e.g. with handle, neck and head, or he may also be only part of the brush, for example, a small plate with openings, which is then encapsulated or inserted into a prefabricated carrier, glued or welded there. All of these variants of brush bodies with openings can be used for the following and aforementioned invention.
- An intermediate container 31 is usually a metal carrier with openings which are arranged according to the tuft pattern of the later brush.
- the stuffing tool 12 also has a tip in addition to the linear guide 28
- a channel 34 formed therein as well as a so-called tongue 36, e.g. has the shape of a long, flat rod that can penetrate into the channel 34.
- the thus separated bristle tufts 20 is then transferred during pivoting clockwise along the guide 22 to the stuffing 12, here to a transfer point 38.
- the tuft singler 10 stops momentarily.
- the tongue 36 is moved to the left. It takes an anchor 40 or a wire loop which has been previously generated for example in a wire cutter.
- the tip 32 then moves to the left towards the brush body 30, and the
- Tongue 36 makes this movement at least at the same speed.
- the tip 32 either stops immediately before the brush body 30 or touches it. Thereafter, the tongue 36 presses the bristle tufts with the folded end together with anchor 40 or wire loop in the opening in the brush body 30th
- the bristle magazine 26 is not visible, but it is carried out according to FIG. 8 and immediately adjacent to the tuft singler 10, which is designed here as a disc 1 14, which has numerous receiving recesses 18 on its circular cylindrical outer periphery 16.
- the receiving recesses 18 bristles are separated into bristle tufts 20 and transported in the direction of the arrow along the guide 22, ie along a circular arc path, into a so-called receiving position for a downstream transfer tool 44.
- the transfer tool 44 is also in the receiving position in which it receives a transported bristle tufts 20.
- the transfer tool 44 serves to pick up bristle tufts 20 from the tuft singler 10, to clamp them on the tuft singler 10 and then to transport them to the tamping tool 12.
- the transfer tool 44 is pivotable about a pivot axis 46 from a receiving position (see FIG. 1) to a delivery position (see FIG. 5). In the receiving position, a bristle tuft 20 is picked up by the tuft singler 10, and in the dispensing position, this picked tuft 20 is delivered to the tamping tool 12.
- the transfer tool 44 comprises at least one, in the present case two axially superimposed holding units, which may optionally be designed as clamping units; Here, for example, in the form of, about the pivot axis 46 pivotable pliers 48 (see in particular Fig. 3).
- the two holding units hold the same isolated bristle tufts 20 at its two halves and therefore provide perfect support and guidance.
- Each pliers 48 has an arm 50, which is designed as a kind of support arm and is directly coupled to the axle 46.
- a clamping arm 52 is provided for each pliers 48, wherein the clamping arm is pivotally coupled via a pin 54 with the support arm 50.
- the clamping arm 52 is e.g. via its own pivoting drive, such as a servo motor, pivoted about the pin 54 relative to the support arm 50 to clamp bristle tufts 20 between the arms 50, 52. Together, the arms 50, 52 are pivoted in a constant relative position to each other in the dispensing position about the axis 46 to a transfer point.
- a cam plate 53 rotatable separately from the arm 50 can control the deflection of the arm 52 via a cam follower 55 mounted on the arm 52.
- a common drive for both pliers 48 which pivots these simultaneously and synchronously about the common axis 46 between receiving and dispensing position.

- the finger 60 has a lateral recess 64 into which a laterally angled end 66 of a clamping finger 68 can penetrate (see Fig. 3).
- the clamping finger 68 is coupled to the clamping arm 52.
- each receiving finger 60 In the receiving position, the receiving fingers 60 are just above and below the edge of the disc 14.
- the slot 62 of each receiving finger 60 is aligned in the direction of rotation to the receiving recess 18 and thus to the incoming bristle tufts 20 in the retraction direction R, so that the incoming bristle tufts 20, without the side to proceed, is moved directly at its opposite end portions in the receiving slots 62.
- FIG. In this position, the clamping arm 52 is pivoted away, so that the cranked end 66, as shown in FIG. 1, is removed from the clamping position and the incoming tuft 20 is not in the way.
- each clamping arm 52 is pivoted, so that the respectively bent finger 66 penetrates into the recess 64 and the Bristle tufts 20 laterally against the finger 60 presses and pinches.
- This clamping then takes place laterally, preferably at right angles to the retraction direction R of the tuft in the slot 62 of the finger 60th
- the bristle tufts 20 is thus clamped at opposite end regions and moved out of the receiving recess 18 in this already clamped state (see FIG. 3).
- the pressing against the tuft 20 portion of the bent end 66 may, as shown in FIG. 4, be concavely rounded in order to achieve the desired tuft cross-section. Also, the end in the retraction direction end of the slot 62 may be rounded to also, for example. to provide a circular tuft cross-section.
- the bristle tufts 20 are pivoted into the dispensing position shown in FIG. 5.
- the takeover tool may also have a linear path along which the singulated bristle tufts 20 are moved to the tamping tool.
- the tool tip 32 When retracting the incoming bristle tufts 20, the tool tip 32 has briefly moved to the left to make room for the incoming bristle tufts 20. Subsequently, the tool tip 32 is moved back again, close to that in the dispensing position, i. bristle tufts 20 located in the transfer point.
- the tongue 36 is moved against the tuft 20 with the anchor 40 or wire (if present), not shown here for clarity, and the tuft is folded into the channel 34 which has a V-shaped inlet portion at the tuft-like end.
- the folded tuft 20 can be seen in this inlet section of the channel 34.
- the clamping arm 52 again moves into the open position, so that the clamping is released.
- the tuft is thus no longer clamped in the transfer tool 44.
- the transfer tool 44 pivots back to the tuft singulator 10, see FIG. 6.
- a stuffing tool can be provided, which is not moved along a rectilinear path, but along a circular path.
- the bristle tufts is usually folded unfolded with one end in the brush body or an intermediate container 31 with openings.
- the hole pattern in the intermediate container 31 corresponds to that of the brush body, so that all bristle tufts from the intermediate container 31 can be pushed into the adjacent brush body.
- the intermediate container 31 serves as a mold half of an injection mold, so that the protruding from the intermediate container bristle tufts are encapsulated to form the brush body and connected to the brush body.
- a centering unit 80 is provided.
- This centering unit 80 aligns the bristles of a bristle tuft 20 and thus, so to speak, the entire bristle tufts in the axial direction, so that the tongue 36 actually engages in the middle of the axial length of the bristle tufts 20 at this.
- the centering unit 80 may, for example, be an active moving unit that presses axially and / or upwardly on the bristle tufts, or it may be a passive unit.

- a contact surface 100 may be present, so that the tuft would then be guided up and down to align all bristles axially equal.
- a contact surface 100 may be movable, as indicated in Fig. 1 by arrows, so that the surface taps against the tuft to move the bristles within the tuft easier to each other.
- the axial length positioning of the tufts can also be achieved by an adjustable contact surface 100.
- FIG. 10 shows a variant of the previously described brush-filling device, which is provided with a centering unit 80.
- the centering unit 80 is arranged to axially displace at least a portion of the transfer tool 44, namely that portion which clamps the bristle tufts 20, so that the bristle tufts are aligned with the plane 106 irrespective of their length.
- FIG. 9 Shown, for example, are three bristle magazines 26, 26 'and 26 ", the bottoms of which (as shown in Figure 9) are at the same axial height, and this embodiment is expressly not limited to these magazines 26.

This displacement can, if two opposite fingers or arms are to be moved, also done together, coupled in the same direction, so that in this case a drive 1 10 may be sufficient.
- the axial displacement and orientation of the bristle tufts removed can be carried out over the entire period of acquisition and support, optionally the clamping of the bristle tufts from the tuft singler 10 to the transfer to the tamping tool. It is not mandatory that in the case where the bristle tufts are held and grasped at their two halves, the holding or clamping points are equidistant from the axial center. It is sufficient if an axial alignment of the removed and further transported bristle tufts takes place at the latest at the transfer of the isolated bristle tufts to the stuffing tool.
- the stuffing tool 12 is shown without the existing stuffing tool 12 for reasons of simplicity, which may optionally be implemented as in the previous figures, which also applies to details of the transfer tool 44 and the tuft singler 10, without thereby being understood as limiting is.

- two-piece transfer tool 44 such as (but not limited to) two axially spaced pliers 48
- two plier 48 may be axially displaced, and lower plier 48 will always engage an axial one Height above the respective bottom 100, 102, 104 on the scattered bristle tufts 20, no matter from which magazine 26, 26 ', 26 "the bristle tufts 20 has been removed.
- Figure 12 shows a variant of the Bürstenstopfvoroplasty according to Figures 1 to 7, wherein in the following only those parts will be discussed, which are different from the parts of the variant according to Figures 1 and 7.
- the essential difference between the variant according to FIGS. 1 to 7 and the variant according to FIGS. 12 to 15 is that the two holding units are not designed in each case as pliers.
- the tuft singler 10 in this embodiment also has a type of disc 14 having at its outer periphery a plurality of circumferentially spaced receiving recesses receiving bristle tufts 20.
- the transfer tool 44 is different in this embodiment.
- each individual bristle tuft 20 is held laterally by the transfer tool 44, optionally clamped, and transferred to the tamping tool 12.
- the transfer tool 44 here has, for example, one or (in the figures) two holding units.
- Each holding unit comprises a so-called tuft picker 122, which is for example plate-shaped and can be pivoted back and forth about an axis.
- a corresponding double arrow in FIG. 12 symbolizes the movement of the tuft picker 122.
- the tuft picker 122 has a radial outer edge 124
- a receiving opening 126 is formed, which is radially outwardly open and which can receive a bristle tufts 20.
- the delimiting element 120 has not only one to the disc 1 14 complementary, minimally spaced from her, the outer periphery of the disc 1 14 opposite edge 131, but also an edge 132 which directly adjacent to the outer edge 124.
- the two edges 131 and 132 merge into each other to form a tip in the region of a tuft deflector 134.
- the peripheral outer edges of the disc 1 14 and the Tuft collector 122 borders, viewed in plan view, directly to each other.
- the separated bristle tufts 20, which are transported one after the other, are transferred directly to the tuft collector 122 in the area of the tuft deflector 134 by the tuft singler 10. This means that the receiving opening 126 is ready in the area of the tuft deflector 134 when the next bristle tuft 20 is transported up.
- the picked bristle tuft 20 is received and held radially (or even clamped) radially between the receiving aperture 126 and the abutment edge 130 and moved along the abutment edge 130 to the tamping tool 12. Even if there is no clamping of the bristle tufts 20, the tuft 20 is held laterally.
- a support surface 108 can secure the tuft 20 against slipping out.
- the bearing surface 108 may also be part of a previously explained centering unit 80.
- the counterpart 128 is stationary and stands.
- the holding unit formed by the tuft collector 122 and the counterpart 128 is positioned axially offset relative to the tuft singler 10, in particular to the pane 14.
- a holding unit is above and a holding unit under the tuft singler 10, seen in side view.
- the bristle tufts 20 are gripped and transported at its two halves.
- each holding unit when embodied as a clamping unit, can also have a clamping finger 68 ', which in this embodiment is, for example, plate-shaped.
- a clamping finger 68 ' In the tuft picker 122, more precisely in each tuft picker 122, is a lateral, ie to the outer edge 124 open receiving opening 140 (see FIG. 14), in which the clamping finger 68 'is pivotably received about an axis 142.
- the axis 142 is shown in FIG.
- a motor-driven pivot arm 144 engages one of the two lever arms of each clamping finger 68 'and pivots both clamping fingers 68' simultaneously about their axes 142.
- the respective opposite lever arm of each clamping finger 68 ' can thereby protrude into the receiving opening 126, seen in the axial direction to reduce the cross-section of the receiving opening and thereby exert a radial force on the bristle tufts 20 to clamp it more secure.
- the clamping fingers 68 ' are pivoted into their receiving position in which they do not or only minimally reduce the free cross-sectional area of the receiving openings 126.
- an axial centering unit can be provided, which moves the holding units axially or only one holding unit moves axially. This can be realized, for example, but not by way of limitation, by means of the centering unit, as shown in FIGS. 10 and 11.
- a central, singular tuft picker 122 is provided, which takes over the separated bristle tufts 20 from the tuft singler 10. This is implemented according to the embodiment of Figure 12 in the variant according to Figures 16 and 17.
- the tuft picker 122 has a laterally open receiving opening 126 (see Figure 17), which receives the isolated bristle tufts 20.
- a counterpart 128 with a concave abutment edge 130 complementary to the outer edge 124 is present.
- This abutment edge 130 is also referred to as a sheet edge.
- the transfer tool 44 shown in Figs. 16 and 17 comprises a central tuft picker 122 and two arms 150 located on axially opposite sides of tuft singler 10 and on opposite axial sides of tuft picker 122 and counterpart 128.
- the arms 150 are each core of the two thus formed, superimposed holding units. In Figure 17, the two superposed arms 150 can be seen.
- the arms 150 are along a circular path having the same center, i. has the same axis of rotation as the tuft picker 122, movable. In addition, the arms 150 but also in the lateral direction (see arrow in Figure 16) can be moved. This lateral movement, like the movement along the circular path, takes place synchronously for both arms 150.
- the arms 150 have a laterally open slot 62 towards the counterpart 128, which is delimited by two adjacent fingers 152, 154.
- the finger 152 closer to the stuffing tool, is laterally longer.
- the movable arms 150 together take over the bristle tufts 20 brought up by the tuft collector 122 at a transfer point to be seen in FIG. 16.
- the abutment edge 130 has a lateral, radially outwardly projecting shoulder 156.
- the counterpart 128 has a concave abutment edge 130 with two arc sections 160, 162, which are connected to each other at the radial shoulder 156.
- the radial shoulder 156 then forms the transfer point from the tuft collector 122 to the arms 150.
- the tuft 20 When the tuft 20 has been transported from the tuft cup 122 to the heel 156, it is pushed laterally outwardly of the receiving opening 126 by the arms 150 and thereby moved radially outwardly at the heel 156 (see FIG. 16).
- the arms 150 collect the tuft 20 together in their slots 62.
- the tuft picker 122 then pivots back to receive the next bristle tuft 20.
- the arms 150 together with the arch portion 162 take over the support of the bristle tufts 20, as shown in FIG. A clamping of the tuft 20 need not necessarily be present here.
- the counterpart 128 also closes the slots 62 of the arms 150 here, even if a common counterpart 128 does not lie in the plane of the arms 150 but in between.
- the common counterpart prevents lateral slipping out of the tuft 20 from the slots 62 of the arms 150th
- a support surface 108 may be present. If appropriate, the support surface 108 can also be moved in the longitudinal direction of the tufts in order to align it, in its axial position, matched to the length of the bristles.
