    Brushware, of which the bristle ends on the side used are rounded and lie in a contour deviating from the surface of the bristle bearer, are manufactured by the method that the bristles are pressed with their ends on the side used with axial displacement against a negative mould corresponding to the contour and are attached by their opposite ends to a bristle bearer. In order to shape individual bristles, bristle bundles or an entire set of bristles and, at the same time to round the ends of the bristles on the side used in an effective and even manner, provision is made for the bristles to be clamped at a distance from their ends on the side used lying in a flat plane, for their ends on the side used to be rounded mechanically or chemically, subsequently to be released from the clamping and then to be shaped against the negative mould. Furthermore, an apparatus for carrying out this method is described.

    The invention relates to a method of making bristle products from synthetic material with bristles and a device for its implementation.
    The purpose of the invention is to improve the quality of products.
    FIG. 1-9 schematically shows all stages of the implementation of the method; in fig. 10-14 - different stages in the manufacture of contoured groups of bristles, for example tufts of bristles; in fig. 15 illustrates an embodiment of the product in the form of a toothbrush, a slit; on
    FIG. 16 shows an embodiment of a round brush, section.
    A method of making bristle products from synthetic yarns consists in that bundle 1 (three bundles are shown in FIGS. 1-9) of long, parallel one other synthetic filaments is fed to guide 1 with channels 3 and flaps 4. Simultaneously with supply of bundle 1 to guide 2 it is conducted through a clamping device 5 with a pusher 6 and channels 7 located in the cut-off zone from the bundle 1 of the individual bundle. Then move for XI N) O O CO

    with
    pressing device 5 along the length of the rope
    The formation of working ends 8 and fixing the non-working ends 9 in the clamping device 5, after which 1 separate bundle (in this case, three pieces) is cut off with a knife 10. In each bundle at the working end, the threads are rounded off by a mechanical (rotating tool
    II is symmetrical to the beam thread) or chemical attack. Place the beams in the additional guide 12 with the channels 13 and the cutting plate 14 and align the working ends of the beams with a plate 15 that moves the beams to the channels 13.
    The working ends of the beams are given a certain shape by axial displacement of the threads of the piece with the working ends from the additional guide in the form 16. They trim the non-working ends, then fix them in the bristle holder (not shown) and remove the form 16, freeing the working ends of the beams.
    An apparatus for carrying out this method comprises a guide 2 for feeding endless bundles 1 of filaments with channels 3 according to the number of bundles 1, a cutting mechanism 10 for separating the bundles from the bundles, means for holding the bundles when fixing their non-working ends in the bristle holder, a clamping device 5 located in p d with a guide 2 in the direction of the harness supply, means 11 for processing the working ends of the threads with rotational drive, a mechanism for shaping the working end of the bundles, containing the shape 16 with blind holes 17 according to the number tufts and a base 18c with pistons 19 mounted with the possibility of axial movement in the channels 13 and acting on the non-working ends of the bundles up to the stop of their working ends into the bottom of the openings 17 of the mold 16.
    The device has an additional guide 12 for placing the non-working ends of the beams and means for translating the beams in the channels 13 in the form of a plate 15 for placing their ends flush with the ends 20 of the clamping device 5 and the additional guide 12. The latter has the channels 13 according to the number of harnesses 1. The number of pistons 19 the base 18 corresponds to the number of channels 13 of the additional guide 12. The pistons 19 have different lengths corresponding to the path of beam movement in the channel 3 of the guide 2. The clamping device 5 is located in a row with n 2 ruler in the feeding direction harness 1 and the cutting mechanism 10 - front clamping device 5, means 11 for processing the working end is located in front of the clamping device 5 with respect to the feeding direction of the harness. The base 18 with the pistons 19 and the additional guide 12 are mounted in a row behind the clamping device 5 and the mold 16 to obtain the length of the non-working ends of the beams needed to secure them in the bristle carrier. A knife 21 is provided for trimming the dead ends.
    The yarn bundle is indicated by the numeral 22. To obtain the final length of the bundle 22, an expansion plate 23 is additionally provided between the clamping device 5 and the mold 16. With the open clamping device 5, the tufts 22 move in the direction of their end on the working side, while the holder 18 with pistons 19 and the mold 16, with the fixed clamping device 5 of the additional guide 12, moves synchronously (Fig. 7) to the right. By this, a gap is formed between the clamping device 5 and the mold 16, into which the spacer plate 23 enters. It has grooves, for example splines or the like, through which the bundles of threads pass. After re-clamping beams using the pusher 6 in the clamping device 5 is cut off by their knife 21.
    Then the spacer plate 23 emerges from the gap between the clamping device 5 and the mold 16 (FIG. 18). The mold 16 moves in the direction of the jig 5 until it is bumped against it. Bundles of threads with ends 24 on the fixation side protrude above the cutting plate 14 to the same length (Fig. 9). In this position, the ends 24 are connected to a bristle holder (not shown) in a known manner.
    FIG. 10-14, a separate tuft of bristles 25 is shown on the basis of three separate bristles 26 lying in the plane of the drawing. The pre-cut and tucked bristles 26 (Fig. 10) are first clamped and trimmed at the ends 27 in the form of rounding (Fig. 11). The individual bristles 26 contour when they are moved in the guide channel by means of the contoured piston, so that, for example, the middle bristle 26 (the greater number of bristles in the middle of the bundle 25) protrudes its end 28 above the rest of the bristles (Fig. 12). The dashed line in FIG. 12 shows a cut to form the ends from the securing side 29, and at 30, 31, different lengths of sections obtained by cutting.
    After contouring, the bristles 26 in the bundle 25 are fixed, melted into a thickening 32 (Fig. 13). The next work operation
    this thickening is fixed inside the bristle holder 33, for example, by injection, foaming or insertion (Fig. 14).
    FIG. 15 shows a toothbrush 34, the back side 36 of which, made integral with the handle 35, is made of plastic. It has tufts of bristles i 37 and 38 of various lengths, the ends of which from working sides 39, 40 respectively lie in the contoured envelope surface and in turn are contoured. The ends of the bristles 37 and 38 are similar to those described in FIG. 13, 14 and can be fixed by means of bulges 41, 42, respectively, on the back side 36 of the toothbrush 34.
    FIG. 16 shows a circular brush 43 used to care for teeth and with the help of an axial support 44 mounted on a drive shaft (not shown). The round brush 43 has an outer bristle crown of tufts 45, which are contoured at the ends on the working side 46, and an inner bristle crown of tufts 47, which are contoured at the ends of the working side 48.
