Definitions

  • the invention relates to a method for fastening bristle tufts for brushes on supports made of thermoplastic, the be installed in the brush body.
  • brush bodies with a Hole field are provided, the desired bristle field corresponds.
  • the bundles of bristles are then in the holes of the Brush body inserted and anchored in it.
  • Anchoring the Bristle tufts in the brush body using anchor plates or loops but requires very powerful and therefore complex machines.
  • the Tufts of bristles attached to a carrier, which is then in a brush body is installed, for example molded during injection molding becomes.
  • the generally platelet-shaped carrier becomes with holes according to the desired hole pattern.
  • the tufts of bristles are inserted into the holes, being on one surface of the support the usage-side ends of the bristle tufts and on the opposite Side the axial ends of the to be anchored in the brush
  • the bristle tufts protrude slightly. This in the brush body too Anchoring ends of the tufts of bristles are then heated together fused and formed into a thickening.
  • the invention provides a method for fastening tufts of bristles for brushes on supports made of thermoplastic created a safe with the simplest procedural steps Anchoring the bristle ends in the carriers is guaranteed.
  • a heated stamp with Protrusions between the holes penetrate into the mass of the carrier and this softens and laterally into the spaces between the bristle tufts repressed.
  • the material of the Carrier softens and deforms so that it ends the bristle tufts tightly and by penetrating the gaps between the Bristles creates a tight fit.
  • the procedure will then use the stamp with its in between the projections at the axial ends of the bristle tufts pressed, the displaced mass of the bristles over the deformed mass of the carrier engages. This creates a intimate bond between the straps and the bristle tufts.
  • the Projections encompass the axial ends of the bristle tufts and give the fused plastic mass a precisely specified shape. During this process, the tufts of bristles preferably become axial held or supported so that they are not in the holes of the wearer be moved axially.
  • the invention also relates to a device for carrying it out of the process, which is heated by a heatable stamp Attack surface is characterized by a variety of protrusions in association with the holes of the bristle field.
  • the platelet-shaped carrier 10 shown in FIG. 1 consists of thermoplastic and comes with a variety of through holes 12 provided, the arrangement of a desired Hole pattern or bristle field of the brush corresponds.
  • the holes 12 are used, as shown in Figure 2, tufts of bristles 14, so that it with the use-side ends 14a on one main surface of the Stand out carrier 10 and on the opposite surface with the The ends 14b to be anchored in the brush protrude slightly.
  • On heatable stamp 16 with a plurality of annular projections 18 is in opposition to the ends 14b of the bristle tuft 14 brought, as shown in Figure 2.
  • the stamp 16 will then, as by an arrow indicated in Figure 2, against the ends 14b of the Bristle tufts 14 moves, the projections 18 initially between the holes 12 or the bristle tufts 14 inserted therein into the Penetrate material of the carrier 10.
  • Material of the carrier 10 softens and at the same time against the tufts of bristles 14 displaced, it also in the spaces between the bristles penetrates, as shown in Figure 3.
  • the material of the carrier 10 also moves radially and encloses the axial ends 14b of the Bristle tufts 14.
  • the material of the softened bristles also becomes also displaced radially and reaches over the shaped elevations of the Carrier between the penetrated projections 18 of the stamp 16 arise, as shown in Fig.
  • the carrier 10 with the bristle tufts 14 anchored therein can be installed in a brush body, for example by Inserting into an injection mold and overmolding with plastic compound.
  • the carriers are mechanically attached to a brush body attached, or they are welded to the brush body, e.g. by ultrasound.
  • Figure 5 shows a greatly enlarged area of the stamp 16, at which the projections 18 pyramid-shaped and ring-shaped with respect to the corresponding holes 12 of the carrier 10, indicated by dashed lines are arranged. The tips of the projections 18 are flattened.
  • Figure 7 shows schematically in plan view one in the larger area of the stamp 16 in the embodiment according to Figure 5, i.e. With pyramid-shaped projections 18 in association with the holes 12 of the Carrier 10.
  • FIG. 8 shows a variant with conical projections 18.
  • Figure 9 shows an embodiment of the stamp according to the in FIG. 6 shows the circular shape of the projections 18.
