    The invention relates to an insertion tool for inserting and fixing tufts of bristles, in particular by means of anchoring plates, into hair holes which are formed in a toothbrush. curved surface of a brush body and / or obliquely in a surface of a brush body, the insertion tool having a slide that can be moved in a slide along an insertion axis to go a receiving position for receiving a tuft of bristles in an insertion position and returning to the receiving position, a push tab being reciprocable with respect to the slide along the axis inserting the insertion tool into a pusher channel and a tool head movable between a receiving position and an insertion position along the insertion axis, provided with a pair of jaws guide for the push-tab, the jaws of which can be moved relative to one another during movement of the tool head from the receiving position to the insertion position. The invention also relates to a brush making machine provided with such an insertion tool.
    Such insertion tools and such brush making machines provided with such insertion tools are known in various embodiments.
    For example, EP 0289059 discloses an insertion tool whose guide jaws are kept movable in the longitudinal direction, the guide jaws of this insertion tool being pushed into a forward position by a force which acts in the direction of movement. 'insertion. When the guide jaws come into contact with the brush body to be filled, they are urged against the force by the brush body and in a manner corresponding to the oblique position of a surface of the brush body by relative to the insertion axis of the insertion tool.
    With regard to this known insertion tool, however, it is not excluded that the brush body is damaged by the guide jaws which come into contact with it.
    It is known from DE 39 35 760 C2 that the two guide jaws of the insertion tool are coupled to one another by means of a rotating part and slideways in the form of oblong holes so that a guide jaw moves forward when the other guide jaw is brought back. Here too, the relative movement of the guide jaws is initiated by the meeting of the guide jaws with the surface of the brush body.
    DE 196 00 193 A1 discloses an insertion tool whose guide jaws are also coupled to one another. To allow alignment of the two guide jaws on an inclination of the surface of the brush body to be filled already before the meeting of the guide jaws with the surface of the brush body, this booklet proposes to bring the two guide jaws in a corresponding relative position by means of a motor and a numerical control.
    The object of the present invention is to provide an insertion tool and a brush making machine of the type mentioned at the beginning which allow an orientation of the guide jaws of the insertion tool adapted to an oblique position or an inclination a surface of the brush body to be filled without contact between the guide jaws and the brush body and without a comparatively complex numerical control and a separate servomotor.
    With regard to the insertion tool defined at the beginning, this object is achieved by the features of claim 1 and in particular the fact that the insertion tool has a return lever connected to the tool head and a deflection slide for the return lever, disposed at a deflection angle with respect to the insertion axis of the insertion tool and that the two guide jaws are coupled to each other through the deflection lever and the return lever is guided in its deflection slide so that a movement of the tool head in the insertion position is linked to an advance of one of the clamping jaws in the direction of insertion and withdrawal of the other guide jaw in the opposite direction to the direction of insertion, the deflection slide being adjustable relative to the insertion axis to change the angle of deflection between insertion axis of insertion tool and the deflection slide. In this way, the two guide jaws are oriented in the desired manner already during the advancement of the tool head. The orientation of the two guide jaws can be adapted in the desired manner to the different orientations of the surfaces and / or the bristle holes of the brush body to be filled by the variable deflection angle that the deflection slide takes with respect to the insertion axis of the insertion tool. It is thus possible to dispense with the use of a comparatively complex numerical control and of a motor with which the guide jaws are driven and oriented relative to each other in insertion tools known in the state of the art. the technique. It should be noted that a change of the deflection angle between the insertion axis and the deflection slide can take place by moving the deflection slide with respect to the insertion axis during operation only between two filling operations.
    It may be appropriate in this case that the front sides of the two guide jaws oriented towards a brush body are offset from each other towards the insertion axis in the insertion position of the head. tool or guiding jaws so that they have a distance comparable to the surface of the brush body in the insertion position. In this way, the two guide jaws take a predefined distance and especially practically identical to the brush to fill hair tufts. This prevents the fixing means, in particular the anchoring plates, used for fixing the tufts of bristles in the respective holes for the bristles of the brush body to escape laterally or to be shifted laterally shortly before introduction into the body. of brush.
    This is possible since the pusher channel through which the fastening means is brought with the tufts of bristles into the respective bristle hole can be extended by means of the guiding jaws positioned at a defined distance from the surface of the bristles. brush body or the orientation of the brush body to be filled or adjacent to its surface, in the hole for bristles to be filled without a significant gap remains for the introduction of the tufts of bristles and means of attachment between the front sides of the guide jaws and an edge of the hair hole. The tufts of bristles can thus be reliably introduced with the fastening means in the hole for bristles concerned.
    It should be mentioned at this stage that the two guide jaws can also, in the insertion position, come into direct contact with the brush body to be lined to achieve even more reliably the transfer or the supply of tufts of hair and means for securing the pusher channel in the bristle hole. The insertion tool according to the invention thus makes it possible, on the one hand, to reliably introduce the tufts of bristles into the bristle holes of the brush body and anchor them thereon and, on the other hand, to also realize the positioning of the guiding jaws necessary for this reliable introduction and anchoring of the tufts of bristles in a way as delicate as possible for the surface of the brush body.
    The deflection slide can be designed in this case as a linear slide. It is further possible that the deflection angle between the deflection guide and insertion axis of the insertion tool is an acute angle. The deflection slide can thus, particularly when it is designed as a linear slide, be oriented at an acute angle, preferably between 0 ° and 45 °, with respect to the axis of insertion of the insertion tool . It may further be appropriate for the deflection angle to be variable, in particular between 0 ° and 45 °, in order to be able to adapt the insertion tool to different insertion tasks or to different brush bodies or hair holes. fill.
    As a function of the angular offset of the deflection slide relative to the axis of insertion of the insertion tool, the two guide jaws of the head coupled to each other are pushed towards each other. other at different distances during the advancement of the tool head into the insertion position to finally exhibit relative to each other, in the insertion position, a desired offset adapted to the body surface brush to provide tufts of hair.
    In the presence of hair holes which are made at an angle, for example, greater than 30 ° in the brush body or in the presence of curved surfaces which have an inclination greater than 30 °, in particular with respect to the insertion axis of the insertion tool, it may be appropriate for the guide jaws to be already offset from one another in the direction of the insertion axis to the receiving position of the tool head and / or guide jaws. One of the two guide jaws can thus already protrude beyond the other insertion jaw in the direction of insertion into the receiving position of the tool head and / or the guide jaws. In such an insertion tool, the two guide jaws thus have, with respect to each other, an offset already adapted to the surface of the brush body to be filled with tufts of bristles. This offset already present in the starting position can then be enlarged by means of the return lever and the deflection slide during the advancement of the tool head in the insertion position to the point that the guide jaws can in the insertion position, to be positioned in the desired manner close to the brush body or adjacent to the brush body even when the latter has an obliquity greater than 30 °, in particular with respect to the insertion axis of the brush body, the insertion tool.
    In order to be able to adapt the insertion tool to different angles at which the hair holes are made in the brush body or to brush bodies with different curves, it may further be appropriate for the deflection slide to be arranged on a adjustment lever for changing an angle between the deflection slide and the insertion axis. It is furthermore possible for the deflection slide and / or the adjusting lever to be pivotable about a pivot axis, in particular by means of a pivoting drive, and / or to be able to be fixed in a pivoting position or selected angle, to change an angle between the deflection slide and the insertion axis.
    In order to be able to connect or couple the two guide jaws with one another by means of the return lever, it may be appropriate for the return lever to be designed in the shape of a T or in the form of a cross. It is also possible that the return lever, particularly when it is designed T-shaped or cross-shaped, has a longitudinal branch and, for each of the two guide jaws, a transverse branch apart, in particular at right angles, of the longitudinal branch and connected rigidly in rotation to the longitudinal branch, each of the transverse branches engaging in use position with one of the two guide jaws.
    When each of the two guide jaws has a receiving groove, in particular oriented perpendicularly to the insertion axis, for the return lever, in particular T-shaped or in the form of a cross, and / or for a transverse branch the return lever associated with the guide jaw, for example one of the transverse branches already described above, in which the receiving groove the return lever and / or the relevant transverse branch engages in the use position with a directed end to the guide jaw, it is possible to make a connection, in particular by form of complementarity, between each of the two guide jaws and the return lever.
    When the transverse branches of the deflection lever have respectively on their ends oriented in the use position towards the guide jaws a deflection roller which engages in the position of use in a groove for receiving the guide jaw, groove already described above, associated with the transverse branch concerned, a friction between the return lever or the two transverse branches and the two guide jaws can be reduced or avoided during the advancement of the tool head or the end position of the two coupled guide jaws, which end positioning is adapted to an inclination / obliquity of the brush body. In this way, it may also be possible to avoid damaging wear for the production process and / or for the insertion tool.
    It may be particularly advantageous if the deflection slide and / or the adjustment lever have two guide branches directed towards each other for the return lever, which have a constant distance relative to each other. on their length.
    In a particularly advantageous embodiment of the insertion tool according to the invention, it can be provided that the return lever has, in particular on a longitudinal branch, for example the longitudinal branch for example already mentioned above, preferably on a free end of the lever facing the deflection slide, a guide member, in particular a guide roller and / or a guide cam, which guide member engages in the position of use in the deflection slide and / or is positioned between the guide branches of the deflection slide. In this way, it may be possible to accurately and reliably guide the diverting lever in the deflection slide which couples the two guide jaws to one another and thus causes and permits the shifting of the guide jaws. relative to each other during advancement of the tool head from the receiving position to the insertion position. The exact guidance of the return lever can contribute at least indirectly to a safe supply of a tuft of bristles in the push channel of the insertion tool, since it allows in the receiving position adjustment and maintenance precise distance between one of the two guide jaws and at least a portion of the slider. This distance between one of the two guide jaws and the slider defines a tuft feeding channel through which the tufts of insertable bristles can be fed to the insertion tool. This should be able to be adjusted and maintained as exactly as possible so that neither the tuft of bristles nor a fastener or anchor plate is lost and / or imprecisely taken during an insertion process, in particular during a feed into the insertion tool.
    It may be particularly advantageous if a longitudinal central axis of a guiding element, for example of the guiding element already described above, of the return lever, in particular an axis of rotation of one or of the guide roller and or a longitudinal central axis of one or of the guide cam is disposed coaxially with a pivot axis of the adjustment lever and / or the deflection slide and / or the guide branch, for example the axis of pivoting already mentioned above, and / or be aligned thereon, when the slide is pushed to the receiving position and / or when the guide jaws are pushed to the receiving position. In this way, it is possible that the two guide jaws can always be brought into their starting position, either with a predefined offset or without shifting with respect to each other, when the slider and / or the head of tool and / or the guide jaws are pushed into their receiving position, regardless of the angle or the deflection angle at which the deflection slide is oriented relative to the axis of insertion of the tool insertion.
    If, in a brush body, several holes or holes for bristles are made at the same angle in the brush body, the deflection slide can in this way remain oriented in a corresponding angular position with respect to the insertion axis of the insertion tool. It is thus possible in this way to avoid a change of positioning of the deflection slide during the return stroke of the insertion tool.
    It is also possible that an imaginary intersection point of a central longitudinal axis of the return lever and the longitudinal center axes of the transverse branches of the return lever is located on or above a longitudinal central axis of the channel pusher in the receiving position and insertion position of the tool head.
    In one embodiment of the insertion tool according to the invention, it can be provided that a pivoting drive of the adjustment lever and / or the deflection slide, for example the pivoting drive already mentioned previously. , has a belt transmission, in particular a toothed belt transmission, by which the adjustment lever and / or the deflection slide can be pivoted about the pivot axis of the adjusting lever and / or the slide deviation.
    In another embodiment, it may be provided that the swivel drive, in particular an output shaft of the swivel drive, is connected directly to the adjustment lever and / or the deflection slide. In this case, the output shaft of the pivot drive and the pivot axis of the adjustment lever and / or the deflection guide can then be arranged or oriented coaxially with each other.
    A uniform transmission of force on the two guide jaws of the head of the insertion tool is possible when the transverse branches of the return lever are arranged symmetrically on the longitudinal lever. It is further possible that a longitudinal central axis of the return lever is disposed on or above a longitudinal central axis of the pusher channel in the retracted position of the slider and / or the tool head and / or guide jaws.
    The above mentioned object is achieved for a brush making machine of the type defined at the beginning by the features of claim 14 and in particular by the fact that the insertion tool is an insertion tool according to any one Claims 1 to 13.
    The brush making machine may have a support on which is arranged an arcuate separator, a box of material with a reserve of tufts of bristles, a clamping device for a brush body to be filled, a feeding means for fixation, in particular for the anchoring material in which the anchor plates are cut, and the insertion tool according to any one of claims 1 to 13. The arcuate separator is designed to take a tuft bristles in the tuft of bristles of the material box and return it to the insertion tool. The insertion tool can then anchor in a hair hole of a brush body oriented obliquely to the insertion axis of the insertion tool or to a surface of the oriented brush body. obliquely to the axis of insertion of the insertion tool the tuft of bristles together with a fixing means, in particular an anchor plate, delivered to the insertion tool by the supply of fastening means. It is especially when the brush body is provided with bristle holes that are oriented at different angles relative to each other and / or relative to the surface of the brush body that it may be appropriate that a device clamping device for the brush body to be filled, for example the clamping device already mentioned above, is arranged on a multi-axis coordinate table. In addition, the multi-axis coordinate table may be arranged, preferably so as to rotate by means of a rotating device, in particular on the support of the brush-making machine.
    In this way, the brush body to be filled may, depending on the orientation of the bristle hole to be trimmed with a tuft of bristles, be brought to the aid of the multi-axis coordinate table and / or the device. rotary device carrying the multi-axis coordinate table in a desired position and orientation with respect to the insertion axis of the insertion tool of the brush making machine.
    An exemplary embodiment of the invention is described in more detail below based on the drawing. It is shown in a representation in part highly schematized in Figure 1: a machine for making brushes according to the invention with a support on which can be seen a box of material with a stock of tufts of bristles, a clamping device for a brush body to be filled, a supply of fixing means, an arcuate separator and the insertion tool according to the invention, the insertion tool being shown in the receiving position relative to the separator in arc of circle, as well as FIG. 2: the machine for manufacturing brushes represented in FIG. 1, the insertion tool being pushed from the receiving position into the insertion position and the two guiding jaws of the head of the insertion tool being adjacent to a surface of a brush body held in the clamping device of the brush making machine.
    FIGS. 1 and 2 show an insertion tool designated in its entirety by 1 on a brush-making machine designated in its entirety by 100. The insertion tool 1 is designed to insert and fix tufts of bristles 2 to by means of fixing means designed as anchoring plates 3 in holes 43 for bristles formed in a curved surface of a brush body or in holes 43 for bristles made obliquely in a surface of a body of brush 4.
    Figures 1 and 2 show that the brush body 4 to be filled is kept ready for insertion on the brush making machine 100 at an angle other than 90 °. The insertion tool 1 has a slider 5 which can be moved in a slider 6 along an insertion axis to go from a receiving position (shown in FIG. 1) to receive a tuft of bristles 2 in an insertion position (shown in Figure 2) and return to the receiving position. The insertion tool 1 is furthermore equipped with a push-tab 8 that can reciprocate with respect to the slide 5 along the axis of insertion of the insertion tool 1. in a pusher channel 7 and a tool head 9 movable between a receiving position and an insertion position along the insertion axis.
    The tool head 9 has a pair of guide jaws 10 and 11 for the push tab 8, the guide jaws 10, 11 being movable relative to each other during the advancement of the head 9 of the receiving position in the insertion position to orient the guide jaws 10 and 11 in a manner adapted to the obliquity of the brush body 4 and holes 43 for bristles.
    To be able to orient in a desired manner the two guide jaws 10, 11 relative to each other and in a manner adapted to the obliquity of the brush body 4 to provide tufts of bristles 2 during the displacement of the head 9 of the tool, the insertion tool 1 has a return lever 12 connected to the tool head 9 and a deflection slide 13 for the return lever 12, which is disposed at a deflection angle relative to the insertion axis of the insertion tool. The two guide jaws 10 and 11 are coupled to each other via the return lever 12 and the return lever 12 is guided in its deflection chute 13 so that a displacement of the head 9 in the insertion position is linked to an advance of one of the guide jaws 10 in the direction of insertion and a withdrawal of the other guide jaw 11 in the opposite direction to the direction of insertion. The deflection slide 13 can be moved relative to the insertion axis to change the angle of deflection between the insertion axis of the insertion tool 1 and the deflection slide 13, the angle of The deviation is therefore variable and the insertion tool 1 can thus be adapted to different brush bodies to be filled and to their geometries.
    The displacement of the deflection slide 13 relative to the insertion axis of the insertion tool 1 can take place, as required, during an insertion operation but also between two insertion operations.
    In the insertion position, shown in Figure 2, of the insertion tool 1 or the tool head 9, the front sides 14 and 15 of the two guide jaws 10 and 11 facing the body of brush 4 have relative to each other, in the insertion position of the tool head 9 or the guide jaws 10, 11, an offset in the direction of the insertion axis so that they have, in the insertion position, a comparable distance with respect to the surface 16 of the brush body 4.
    In the exemplary embodiment of the insertion tool, shown in FIG. 2, the two end faces 14 and 15 of the two guide jaws 10 and 11 rest, in the insertion position, on the surface 16 of the body of the brush 4 or are at a negligible small distance which does not affect the reliable transfer of the tufts of bristles 2 with the anchoring plates 3.
    A movement of the guide jaws 10, 11 thus goes along with a displacement of one of the guide jaws 10 in the direction of insertion and a displacement back of the other guide jaw 11 in the direction opposite to the direction insertion.
    As both figures show, the deflection slide 13 is designed as a linear slide and is oriented at an acute angle to the axis of insertion of the insertion tool. The angle or the angle of deflection between the deflection slide 13 and the insertion axis of the insertion tool 1 is about 30 ° in the embodiment of the insertion tool shown in the figures but can be freely adjusted at least in an angular range between 0 ° and 45 °.
    In an exemplary embodiment of the insertion tool 1 not shown in the figures, the guide jaws 10 and 11 are already offset from one another in the direction of the insertion axis in the receiving position of the tool head 9 or the guide jaws 10, 11. This means that one of the two guide jaws 10, 11 is already in the receiving position of the tool head 9 or the guide jaws 10, 11 above the other guide jaw 11 in the direction of insertion.
    This is advantageous when surfaces 16 of the brush body 4 are to be filled with tufts of bristles 2 which are held ready at an angle greater than 30 ° with respect to the insertion axis on or for the tool. insertion 1.
    The deflection slide 13 is disposed on an adjusting lever 17 to change the deflection angle between the deflection slide 13 and the insertion axis. The insertion slide 13 may by means of a pivot drive 18 be caused to pivot about a pivot axis S together with the adjustment lever 17 to change the deflection angle between the deflection chute 13 and the insertion axis of the insertion tool 1 and can be fixed in a pivoting or angular position chosen with respect to the insertion axis of the insertion tool 1.
    The two figures show that the return lever 12 is designed T-shaped or cross-shaped and has a longitudinal branch 19 and, for each of the two guide jaws 10, 11, a transverse branch 20 or 21 which s separates at right angles from the longitudinal branch 19 and is connected rotatably to the longitudinal branch 19, each of the two transverse branches 20 and 21 applying in the use position on one of the two guide jaws 10, 11 so that the two guide jaws 10, 11 are coupled, on the one hand, to the return lever 12 and, on the other hand, to one another via the two transverse branches 20 and 21 and can be pushed towards each other in the desired manner, during advancement of the tool head 9 into the insertion position, interacting with the deflection chute 13.
    Each of the two guide jaws 10, 11 is further equipped with a receiving groove 22 or 23 oriented perpendicularly to the axis of insertion of the insertion tool 1, for the return lever 12 or again to each of the transverse branches 20, 21 of the return lever 12 T-shaped associated with the two guide jaws 10, 11. The return lever 12 engages in these receiving grooves 22, 23 with one end 24 or 25 d one of its two transverse branches 20, 21, which end is directed towards the guide jaw 10, 11, to establish a form-complementary connection between the guide jaw 10, 11 concerned and the deflection arm 12 in position d 'use.
    The transverse branches 20 and 21 of the return lever 12 have at their ends 24 and 25 respectively directed towards the guide jaws 10, 11 in the position of use a deflection roller 26, 27 which engages in the position of use in a receiving groove 22, 23 of the guide jaw 10 or 11 associated with the transverse branch 20, 21 concerned.
    The deflection slide 13 is formed by two guide branches 28 and 29 which are oriented parallel to each other and have a constant spacing along their length.
    The return lever 12 has at a free lever end 30 of the longitudinal branch 19, which end is directed towards the deflection chute 13, a guide element 31 which is designed as a guide roller 32 in the embodiment of FIG. the insertion tool 1 shown in the figures. This guide element 31 engages in the position of use in the deflection slideway 13 and is positioned between the two guide branches 28 and 29 of the deflection chute 13.
    In this way, the guide element 31 designed as guide roller 32 can roll on the two parallel guide branches 28 and 29 and thus transmit the movement of the return lever 12 to the guide jaws 10 and 11 associated with the transverse branches 20 and 21 through the longitudinal branch 19 and the two transverse branches 20 and 21.
    In an exemplary embodiment of the insertion tool 1 not shown in the figures, the guide element 31 is designed as a guiding cam which can slide in both directions in the deflection chute 13 between the two guide branches. 28 and 29.
    FIG. 1 shows that the guide roller 32 of the deflection lever 12 is arranged coaxially with the pivot axis S of the adjustment lever 17 and with the deflection slide 13 as well as with the guide branches 28 and 29 when the slide 5 is pushed into the receiving position and when the guide jaws 10, 11 are pushed into the receiving position. This means that an axis of rotation of the guide roller 32 of the return lever 12 is aligned with the pivot axis S of the adjustment lever 17, so that the adjustment lever 17 can be guided particularly accurately in the deflection slide 13.
    In addition, an imaginary intersection point of a central longitudinal axis of the return lever 12 and the longitudinal central axes of the transverse branches 20 and 21 of the return lever 12 is located in the receiving position and in the insertion position of the tool head 9 on or above a longitudinal central axis of the pusher channel 7 according to the two figures.
    According to the two figures, the swivel drive 18 of the adjusting lever 17 and / or the deflection chute 13 is equipped with a belt drive 33 which is designed in the present embodiment as a toothed belt drive. With this belt transmission 33, the adjusting lever 17 and the deflection chute 13 are pivoted about the pivot axis S of the adjusting lever 17 and the deflection chute 13 to adjust an angle or angle of rotation. desired deflection between the deflection slide 13 and the insertion axis of the insertion tool 1.
    In an exemplary embodiment of the insertion tool 1 not shown in the figures, the pivoting drive 18 is connected directly to the adjustment lever 17 or to the deflection chute 13 via a control shaft. output of the swivel drive 18. In this case, the output shaft of the swivel drive 18 and the swivel axis S of the adjustment lever 17 or the deflection guide 13 are coaxially arranged therein. one in relation to the other, so turn around the same axis.
    The two figures show that the transverse branches 20 and 21 of the return lever 12 are arranged symmetrically on the longitudinal lever 19 and that a longitudinal central axis of the return lever 12 is disposed in the retracted position of the slider 5 and the head 9. of the tool as well as the two guide jaws 10 and 11, on or above a longitudinal central axis of the pusher channel 7.
    The brush machine 100 in its entirety has the insertion tool 1.
    The brush making machine 100 has a support 34 on which is disposed an arcuate separator 35, a box of material 36 with a reserve of tufts of bristles 37, a clamping device 38 for a brush body 4 to be filled , a supply of fixing means 39 and the insertion tool 1.
    The arcuate separator 35 has an arcuate notch 40 with which it is guided on a lower side of the box of material 36 along a circular arc and takes a tuft of bristles 2 in the tuft bank bristles 37 which is pressed against the arcuate separator 35 by means of a pressure spring 41 and a press 42 and returns it to the insertion tool 1. The insertion tool 1 then anchors in a manner known per se, in a hole 43 for bristles of the brush body 4, by means of the push-tab 8, the tuft of bristles 2 together with a fixing means which is delivered to the insertion tool 1 by the supply of fixing means 39 and is in this case an anchor plate 3.
    It should be mentioned at this point that a distance L between the upper guide jaw 10 of the tool head 9 and the slider 5 must be exact when introducing a tuft of bristles 2 by the arch splitter. of circle 35 until the collection of the tuft of bristles 2 of the notch in an arc of circle 40 by means of the anchoring plate 3 which is pushed through the pusher channel by the push-tab 8. If this distance L is too small, the tufts of bristles 2 will not be introduced correctly by the arcuate separator 35. If the distance L is too large, the anchoring plate 3 may be lost.
    The exact guidance previously described of the return lever 12 which is made possible by the aligned and coaxial arrangement, visible in particular in FIG. 1, of the axis of rotation of the guide element 31 designed as a guide roller 32 in relation to to the pivot axis S of the adjusting lever 17 contributes to a reliable supply of a tuft of bristles 2 in the pusher channel 7 of the insertion tool 1, in that it allows an adjustment and a precise maintenance of the distance designated L between the upper jaw of the two guide jaws 10, 11 and at least a portion of the slider 5 in the receiving position. This distance L between that of the guide jaws 10, 11 which is above in the figures and the slider 5 defines, in particular according to Figure 1, in the receiving position of the slider 5 and the tool head 9 and the two guide jaws 10, 11, a tuft feeding channel 48 through which the tuft of bristles 2 to be inserted is fed to the insertion tool 1. The supply of fixing means 39 comprises a roller 44 on which is wound an anchor wire and a knife 45 with which individual anchoring plates 3 are cut from the anchor wire brought to the insertion tool 1 via the supply of means fixing 39.
    As shown in both figures, the clamping device 38 for the brush body 4 to be filled is arranged on a multi-axis coordinate table 46 which is pivotally arranged on the support 34 of the brush making machine. 100 by means of a rotary device 47. Using the multi-axis coordinate table 46 and the rotary device 47, the brush body 4 kept ready to be filled in the clamping device 38 can be kept oriented to at almost any angle to the axis of insertion of the insertion tool 1. The brush body 4 is always oriented so that a central longitudinal axis of a hole 43 for bristles or d a hole hole for bristles is in the rectilinear extension of the insertion axis of the insertion tool 1 or with respect to the longitudinal central axis of the push channel 7.
    According to FIG. 2, the two guiding jaws 10 and 11 in the insertion position are adjacent to the brush body 4 to be filled with tufts of bristles 2, which is advantageous, since thus anchoring plates 3 and tufts of bristles 2 carried by the push tab 8 through the push channel 7 can not escape laterally as the push channel 8 passes through the hole 43 for the bristles concerned but are reliably introduced into the hole 43 for bristles to provide the tuft of bristles 2 and the anchor plate 3 in the brush body 4 and be anchored there. The insertion tool 1 is arranged to insert and fix tufts of bristles 2, in particular by means of anchoring plates 3, into holes 43 for bristles formed in a curved surface of a brush body 4 and / or or holes 43 for bristles made obliquely in the surface of a brush body 4, the insertion tool 1 having the slide 5 which can be moved in the slide 6 along an insertion axis to go a receiving position for receiving a tuft of bristles 2 in an insertion position and return to the receiving position. The insertion tool 1 furthermore has the push-tab 8 capable of reciprocating with respect to the slider 5 along the axis of insertion of the insertion tool 1 into the channel 7 and the tool head 9 can be moved along the axis of insertion between a receiving position and an insertion position. It is equipped with two guide jaws 10 and 11 through which the push tab 8 pushes the tuft of bristles 2 together with an anchor plate 3 in a hole 43 for bristles to provide a tuft of bristles 2 .
    The two guide jaws 10 and 11 can be moved relative to each other during the advancement of the tool head 9 from the receiving position into the insertion position to adapt the two guide jaws 10 , 11 at the inclination or obliquity of a surface 16 of the brush body 4 and / or holes 43 for bristles. In order to be able to move the two guide jaws 10 and 11 relative to one another, the insertion tool I has the return lever 12 connected to the tool head 9 and the deflection slide 13 for the return lever 12, the two guide jaws 10 and II being coupled to the return lever 12 and the return lever 12 being guided in its deflection chute 13 so that a displacement of the tool head 9 in the insertion position is linked to an advancement of a guide jaw 10 in the direction of insertion and a withdrawal of the other guide jaw 11 in the opposite direction to the direction of insertion, the deflection slide 13 that can be adjusted relative to the axis of insertion to change the angle of deflection between the insertion axis of the insertion tool 1 and the deflection slide 13.
