  • the invention relates to a method for fusing the axial Ends of bundled fibers made of thermoplastic plastic Exposure to heat.
  • the invention further relates to a device for attaching tufts of bristles for brushes to carrier plates thermoplastic plastic.
  • the carrier plates with the on them attached bristle tufts are built into the brush body, especially for the production of toothbrushes.
  • the tufts of bristles attached to a carrier plate, which then in a Brush body is installed.
  • the carrier plate can with the brush body can be connected by injection molding or welding.
  • the carrier plate is provided with holes according to the desired hole pattern.
  • the tufts of bristles are inserted into the holes, taking on a surface of the carrier, the ends of the bristle tufts on the usage side and on the opposite side those to be anchored in the brush
  • the axial ends of the bristle tufts protrude slightly.
  • the invention provides a method for fusing fiber ends provided in which the fused fiber ends clean of let the heated surface peel off and one by the shape of the surface have certain geometry. In the process, the fiber ends brought into contact with a heated surface, which then suddenly is cooled. Only after the surface has cooled down are the Fiber ends separated from this.
  • the method is particularly suitable for the production of tufts of fibers for the production of brushes. Fibers for brush production mostly consist of a thermoplastic Plastic such as poyamide ("nylon"). This material leaves shape well with the given procedure.
  • the invention also provides a device for fastening Bristle tufts on carrier plates for the production of brushes for Provided with the influence of the stamp on the Bristle ends are carried out in a controlled and reproducible manner, so that the desired deformation of the bristle ends without undesirable Deformation of the carrier plate is guaranteed.
  • Device is stamped by electrical current flow heated and cooled by a flowing cooling medium.
  • the Stamp can be heated very quickly and specifically by electrical current flow, especially if it is in accordance with the preferred embodiment has a low heat capacity, so that it is then by the flowing cooling medium can be cooled quickly again. Since the Bristle ends heated only for a short time and then immediately are cooled again, smearing of the heated bristle material avoided on the carrier plate.
  • the carrier plate itself is only slightly heated, since the stamp through the electrical current flow only for a short time to fuse the Bristle ends heated temperature and then immediately again is cooled.
  • the electrical current flow in particular by pulse duration modulation, the strength and duration of the Control heating well.
  • the stamp preferably has a body made of electrically conductive Material on which two electrical high-current connections in the form of angled contact shoes are formed.
  • the body of the stamp has a thin-walled stamp plate that is angled by a Edge strips can be stiffened.
  • Suitable materials for manufacturing of the stamp are metals that on the one hand have sufficient mechanical Have strength so that for rapid temperature changes desired low heat capacity is guaranteed, on the other hand but have a relatively high specific resistance, thus the electrical heating power through an uncritically low electrical voltage can be provided.
  • the necessary Heating currents are then a hundred amperes and more, for example, two hundred amps at 7 volts, but can be control such high currents well with available semiconductor elements. Due to the criteria mentioned are stainless steel, titanium and NiCr-containing alloys suitable materials for the production of the Stamp.
  • Compressed air is preferably used to cool the stamp. Because of the low heat capacity of the stamp can be directly Blowing with compressed air can be cooled again in a very short time, so that Cycle times in the range of one second are possible.
  • stamps there are several stamps arranged in a group on a stamp carrier plate, and the the same number of carrier plates is placed opposite the stamps inserted into corresponding openings in a support plate.
  • the stamp are preferably electrically connected in series on the stamp carrier plate, so that the current of the heating current does not increase. This Measure is particularly useful if the stamp carrier plate with the stamps relative to the carrier plates arranged in the support plate is moved back and forth, then the electrical leads for the heating current must be moved, so that large conductor cross sections would be unfavorable.
  • the stop 3 can be flat or have a profiled shaped surface and thus for profiling the bristles by axially moving the bristles be used in a known manner.
  • the free fiber ends are opposite to an electrical current flow heatable stamp 4, of any shape, especially with a molded surface.
  • the stamp 4 has a small one Heat capacity so that it is very much by electrical resistance heating heated quickly and just as quickly by a flowing cooling medium can be cooled again.
  • a first phase the stamp 4 is heated and against the fiber ends pressed, as shown in Fig. 2.
  • the fiber ends fused and reshaped.
  • a second phase Fig. 3
  • the stamp 4 quickly cooled by targeted blowing with compressed air. Only then is in a fourth phase, Fig. 4, the stamp of the now fused and cleanly formed fiber ends separated.
  • this is used for Manufacture of toothbrushes in which a tuft of bristles is provided Carrier plate inserted into a brush head and welded to it becomes.
  • Details of such a device are, for example EP 0 972 464 A1 and EP 0 972 465 A1.
  • a stamp carrier plate 12 On a stand 10 is a stamp carrier plate 12 by means of guide rods 14 arranged vertically back and forth, the drive is ensured by a pneumatic cylinder 16.
  • a pneumatic cylinder 16 At the Four support bases 18 are fastened to the underside of the carrier plate 12, which each carry a heatable stamp 20 directed downwards.
  • a carrier plate 26 can be used made of plastic, with a perforated field corresponding to the desired bristle field is provided.
  • a compressed air line 28 branched on the stamp carrier plate 12 can be delivered to the device targeted compressed air blows that are directed directly at the stamp 20.
  • To the stamp carrier plate 12 also carry two flexible power cables 30, one via pulse duration modulation regulated electrical current can be supplied.
  • This stamp 20 the design of which can be seen in more detail in FIG. 8 is made of a metallic body, especially stainless Steel, with a thin-walled stamp plate 20a and two molded, angled high-current connections in the form of rectangular Contact shoes 20b, 20c. These contact shoes 20b, 20c serve simultaneously to attach the stamp 20 to the support base 18, via the further the electrical connection of the four stamps 20 is accomplished. How 6 can be seen, the power cables 30 are each immediately connected to a cable lug.
