    The invention relates to a cutting machine for cutting to length a stock of pile filaments formed of a plurality of pile filaments and designed at least in a free end region such as a flat strip-shaped beam. hair filament bundle segments, comprising a feeding device by which the free end region of the pile filament stock can be moved towards a cutting device which has a cutting blade and a counter blade provided with a cutting edge, which cutting blade and cutting edge can be moved relative to one another in a cutting position to cut and lengthen the pile filament bundle segments.
    Mascara brushes or interdental brushes are already known in which a flat band-shaped hair liner is held between two sections of wire twisted together in a spiral shape so that the pile lining also takes the form of a helix or of spiral. For brushes that are twisted this way, the pile filaments used for the hair trim are always thinner. Since hair filaments of less than two or three mil (1 mil = 1 thousandth of an inch = 0.0254 mm) are increasingly used, the stiffness of the individual pile filaments is also necessarily always lower.
    During the lengthening of the segments, necessary for the filling of bristles, a bundle of filaments of bristles shaped flat strip serving as a reserve of hair filaments in a cutting device consisting of a cutting blade and d Against a blade, it is found that some of these thin pile filaments remain stuck to the counterblade after cutting or shearing. This adhesion may be due to very small fusions that form during the cutting process or that occur due to the static charge of the pile filaments.
    In the case of thicker pile filaments, the adhesions dissolve because the rigidity of the pile filaments is greater during the advancement. In the case of thinner pile filaments, it may happen that at least one of the pile filaments used for the pile lining still adheres to the counterblade after the end of advancement and protrudes from the counterblade. in one arc, which can lead to operational disturbances in the cutting device or to a defective lining of the brush. Such undesirable adhesions are further promoted because the pile filaments may have not only a round pile filament cross-section but also a triangular, parallelepipedal, star-shaped cross section or other oval cross sections. The roughness or similar nature of the hair filaments can play also play a role; Thus, surface coatings, such as for example a layer of wax applied to the pile filaments, can cause the latter to stick to the counterblade.
    The problem therefore consists in producing a cutting device of the type mentioned at the beginning with which, as far as possible, all the pile filaments can be safely detached from the cutting edge of the counter blade after the cutting process.
    The solution according to the invention to this problem consists for the cutting device of the type mentioned at the beginning in particular in that the cutting edge can be moved between the close cutting position of the cutting blade and a spaced detachment position against the cutting blade and in that the counterblade is movably guided and / or is mounted so as to rotate relative thereto.
    In addition or instead, another proposed solution to the above problem provides that the advancing device can be moved between a position close to the cutting edge of the counterblade and a detachment position spaced apart by against the cutting edge and that the advancing device is movably guided and / or rotatably mounted thereon.
    In order to be able to detach the hair strands which initially still adhere to the counter blade from the counterblade after the cutting process, the present invention provides in a concordant manner to allow the transverse forces such as these hair filaments to act on the pile filaments. can completely detach from the counterblade and its cutting edge. It is possible in this way to avoid malfunctions of the cutting machine according to the invention, which could otherwise be due to the pile filaments adhering to the counterblade. The cutting device of the cutting machine according to the invention also has a cutting blade and a counter blade with a cutting edge which can be moved relative to one another in a cutting position for cutting or shearing or lengthening the pile filament bundle segments. To be able to let such transverse forces act on the pile filaments, it is provided according to said proposal according to the invention that the cutting edge can be moved between the close cutting position of the cutting blade and a spaced detachment position. on the other hand, the cutting blade and the counterblade is movably guided and / or rotatably mounted thereon. In addition or instead, it is also possible that the advancing device can be moved between a close position of the counterblade and a detachment position spaced from the counterblade and the advancement device is movably guided and / or rotatably mounted thereon.
    To bring the cutting edge to the counterblade away from the cutting blade, the counterblade can be rotatably mounted. But it is also possible that the against-blade is in addition or instead guided movably. Thus, an advantageous embodiment according to the invention provides that the counter-blade is movably guided in a plane of movement arranged transversely and preferably at right angles to the flat side of the terminal region free of the stock of hair filaments.
    Another embodiment according to the invention provides that the counterblade is guided in a displaceable manner transversely and preferably at right angles to the sides of the free end region of the stock of pile filaments.
    In order to be able to store as large a stock of pile filaments as possible in the cutting machine according to the invention, it is appropriate for the stock of pile filaments to be stored on at least one storage roll.
    In order to be able to bring the free end region of this stock of hair filaments to the cutting device in the cutting machine according to the invention, the feeding device is necessary, the latter preceding the cutting device in the direction of advancement. A preferred embodiment according to the invention provides that the advancing device has two clamping elements which can be moved relative to each other and are movable in the advancing direction to clamp a partial region of the stock of hair filaments. Due to the displacement of the two clamping elements relative to each other, the free end region of the pile filament supply, which is intended to be lengthened, can be clamped between the clamping members and then moved in the direction of advancement to the cutting device.
    In an embodiment in which the advancing device is rotatably mounted and / or movably guided relative to the counterblade, it may be advantageous that the clamping members of the advancing device can be moved to the detachment position spaced apart from the cutting blade, particularly when the pile filament bundle segments have been gripped by the gripper. A preferred embodiment according to the invention provides that the clamping elements of the feed device which are in their stop position can be moved upwards in the detachment position spaced apart from the counter-blade and in particular its cutting edge;
    In particular, in an embodiment in which the counterblade is displaceably guided and / or rotatably mounted, it may be advantageous that a first of the two clamping elements of the feed device which can be moved in the advancing direction is held immobile transversely to the advancing device and a second clamping member can be moved towards and away from the first clamping member. To be able to move the free end region of the stock of pile filaments towards the cutting device, the two clamping elements of the cutting device can be moved in the direction of advancement. To grasp the free end region of the pile filament stock and to be able to clamp it between the clamping members, the second clamping member can be moved toward and away from the first clamping member.
    A preferred improvement according to the invention provides that the first clamping element preferably disposed below the end region of the stock of pile filaments is designed in the form of a plate or bridge and that the second clamping element disposed in particular at above the free end region of the stock of pile filaments has at least one rubber insert. If the first clamping member is disposed below the end region of the stock of pile filaments, the stock of pile filaments is functionally reliably pushed by the feed device. By moving the second clamping member towards the first clamping member of the feed device, the end region of the stock of pile filaments to be lengthened can be appropriately gripped and moved towards the cutter. Proper gripping of the end region of the stock of pile filaments is further ensured by the fact that the second clamping element of the feed device, which can be moved towards the first clamping element, has at least one rubber insert .
    A safe mode of operation of the cutting machine according to the invention is furthermore ensured when the free end region of the pile filament supply is guided below an upper delimiting element and / or between two lateral delimiting elements. .
    To avoid adhesion of the individual pile filaments to the delimiting elements of the cutting machine according to the invention, it is appropriate that at least one of the lateral delimiting elements can be moved transversely to the direction of advancement of the terminal region. free from the stock of hair filaments.
    In order to be able to produce the pile lining required for a twisted brush, it is appropriate that a gripping device be provided which clamps and grasps between two sections of yarn the portion, intended as a pile filament bundle segment, of the region. free end of the stock of pile filaments, preferably before the cutting device in the direction of advancement. The portion provided as a hair filament bundle segment at the free end of the pile filament store is gripped between two sections of yarn and is still held in a first time between these two sections of yarn even after the stitching. the necessary pile filament bundle segment.
    In order to be able to shape the pile lining retained between two sections of yarn and to obtain a mascara brush or a twisted interdental brush, it is appropriate for the pile filament bundle segment retained between two sections of yarn to be able to of the stock of pile filaments, be moved by means of the gripping device to a twisting device in which the sections of yarn are twisted or twisted with each other in pairs.
    Improvements according to the invention emerge from the description of the figures which follows in relation to the claims as well as with the drawing. The invention will be described in more detail below on the basis of exemplary embodiments.
    It is shown in fig. 1 a cutting machine shown in a perspective view, which has a cutting device provided with a cutting blade and a counterblade with a cutting edge, the counterblade being rotatable; a close cutting position of the cutting blade in a detachment position spaced therefrom, FIG. 2 the cutting machine of Figure 1 directly after the cutting process during the spacing by rotation of the cutting edge provided on the counter blade, FIG. 3 the partial region of the stock of pile filaments advancing above the cutting device and cutting as a pile filament bundle segment, FIG. 4 the partial region of the pile filament supply provided as hair filament bundle segment directly with the cutting process, the partial region of the pile filament supply already advancing above the cutting device and provided as a beam segment being clamped and retained between two sections of wire, FIG. 5 a cutting machine made in a manner comparable to that of Figure 1 to 4, provided with a cutting device, the counter blade cooperating with the cutting blade being here designed in the form of block or plate and can be moved transversely and in particular at right angles to the plane of movement of the stock of hair filaments, FIG. 6 the cutting blade and counterblade of the cutting machine of FIG. 5 guided in opposite directions after the cutting process, FIG. 7 the cutting machine of FIGS. 5 and 6 directly before cutting a hair filament bundle segment in the cutter, and FIG. 8 the cutting machine of FIGS. 5-7 with the free end region of the stock of pile filaments retained between two sections of yarn and provided as a pile filament bundle segment directly prior to the cutting process.
    Figures 1 to 8 show two embodiments 1, 10 of a cutting machine which is intended to cut to length a stock of pile filaments 2 formed of a plurality of pile filaments into individual flat pile filament bundle segments. . This stock of pile filaments 2, which is stored here on at least one storage roll 3, is designed as a flat strip-shaped beam in its free end region 4 intended to be cut to length.
    The cutting machines 1, 10 has a feed device 5 by means of which the free end region 4 of the pile filament stock 2 can be moved towards a cutting device 6. The cutting device 6 has a cutting blade 7 and a counterblade 8 having a cutting edge 9. The cutting blade 7 and the cutting edge 9 can be moved relative to each other in a cutting position for cutting or shear or lengthen the hair filament bundle segments.
    To prevent adhesion of thin individual pile filaments to the counterblade 8, its cutting edge 9 can be moved between the close cutting position of the cutting blade 7 (see Figs 1 and 5) and a position of detachment spaced against the cutting blade 7 (see Figures 2 and 6). It is clear from the comparison of Figures 1 and 2 on the one hand and Figures 5 and 6 on the other hand that the counterblade 8 is further guided movably and / or mounted so as to rotate. After the cutting process, the counter blade 8 can thus be rotated and / or moved in such a way that the cutting edge 9 on the counterblade 8 is moved from the close cutting position of the cutting blade 7 in a detachment position spaced therefrom, in which the detachment position of the individual pile filaments still adhering initially to the counterblade 8 has become detached. Due to the movement of movement or rotation of the counterblade 8, such transverse forces act on the pile filaments that the pile filaments still adhering at the beginning are detached from the cutting edge 8 of the counterblade 8 In this way it is possible to avoid malfunctions of the cutting machine 1, 10 according to the invention, which could otherwise be due to the pile filaments adhering to the counterblade 8.
    In embodiment 1 of the cutting machine shown in FIGS. 1 to 4, counterblade 8 is rotatably mounted. As can be seen in FIG. 2, the counterblade 8 can, after moving away from the cutting blade 7, rotate about its longitudinal axis so that its cutting edge 9 moves away from the cutting blade 7.
    It will be clear on the basis of the cutting machine 10 shown in FIGS. 5 to 8 that an undesirable adhesion of pile filaments can also be avoided by moving the counterblade 8. As can be seen from a comparison of FIGS. at 8, the counterblade 8 of the cutting machine 10 is displaceably guided in a plane of movement arranged transversely and preferably at a right angle to the flat side of the free end region 4 of the pile filament reserve. 2. In an embodiment of the cutting machine which is not depicted, against the blade 8 can also be guided in a displaceable manner transversely and preferably at right angles to the (small) sides of the free terminal region 4 of the stock of hair filaments 2.
    It can be seen in Figures 4 and 8 that the cutting machines 1, 10 have a gripping device 11 which clamps and grasps between two sections of wire 12, 13 the part, provided as a segment of hair filament bundle, the free end region 4 of the stock of pile filaments 2. The pile filament bundle segment clamped and grasped between the two sections of yarn 12, 13 and cut to the length of the stock of pile filaments 2 is mu, after the cutting the length of the pile filament stock 2 by means of the gripper 11 to a twisting device not shown here in which the yarn sections 12, 13 are twisted or twisted with each other in pairs of such that the flat-band-shaped pile filament bundle segment between these twisted yarn sections 12, 13 also takes a spiral or helical shape, as is usual for mascara brushes or even for interdental brushes.
    The wire sections 12, 13 may be separated from one another or may also be connected to one another at one of their ends.
    It is clear from a comparison of FIGS. 1 to 4 on the one hand and from FIGS. 5 to 8 on the other hand that the feed device 5 of the cutting machines 1, 10 has two clamping elements 14, 15 which can be moved relative to each other to clamp a partial region of the pile filament stock 2 and can be moved in the advancing direction. In the cutting machines 1, 10 shown here, a first 14 of the two clamping elements 14, 15 of the feed device 5 which can be moved in the direction of advance is held immobile transversely to the feed device and a second clamping element 15 can be moved towards and away from the first clamping member 14. Due to the displacement of the two clamping elements 14, 15 relative to each other, the free end region 4, intended to be cut to length, of the stock of pile filaments 2 can be clamped between the elements of FIG. 14, 15 and then - as is apparent from a comparison for example of Figures 1 and 4 and 5 and 8 - can be moved towards the cutting device 6. Proper entry of the terminal region 4 of the reserve of hair filaments 4 is further ensured by the fact that the second clamping element 15 of the feed device, which can be moved towards the first clamping element 14, has at least one rubber insert. The first clamping member 14 is designed as a plate or bridge to ensure high positional accuracy. While the first clamping member 14 is disposed below the free end region 4 of the pile filament stock 2, the second clamping member 15 is provided above the free end region 4. The free end region 4 the stock of pile filaments 2 may also be guided between two lateral delimiting elements, at least one of which may be moved transversely to the direction of advance of the free end region 4 of the pile filament reserve 2.
    In the cutting machine 10 shown in FIGS. 5 to 8, the counter blade 8 is guided in a linearly displaceable manner. To cut the pile filament bundle segments, the cutting blade 7 in the cutting machines 1, 10 can be moved upwards towards the cutting edge 9 of the counter blade 8. in Figures 1 to 4 and 5 to 8 that in the cutting machines 1, 10 shown here, the gripping device 11 is disposed behind the cutting device 6 in the direction of travel. But it is also possible that the gripping device already grasps the free end region 4 of the stock of pile filaments 2 before the cutting device 6 in the direction of advance and that in addition the gripping device 11 is arranged before the cutting device 6 in the direction of advancement. It can be seen in FIGS. 1 to 4 that the counterblade 8 can be turned forwards in the detachment position in the direction of advancement while on the other hand the hair filament bundle segment provided as a fur trim stay motionless; as a result, this pile lining is detached from the cutting edge 9 of the counterblade 8 while the cutting edge 9 moves downwards due to the rotational movement of the counter blade 8. the cutting machines 10 shown in FIGS. 5 to 8, the counterblade 8 is in contrast pulled down from the cutting position to the detachment position, while the gripper 11 still holds the beam segment hair filaments provided as a hair pad. The pile filament bundle segment is preferably maintained in the middle between the thread sections 12, 13. For a larger pile lining, the pile filament stock 2 can be stored on a plurality of storage rolls 3. The filaments bristles are then drawn from the at least one storage roll 3 by means of the advancement device 5.
