Definitions

  • the invention relates to a method for configuring the use-side bristle ends of at least one bristle bundle in the manufacture of bristle articles, in particular toothbrushes, in which the bristle bundle inserted into a channel of a carrier and cut to a predetermined size with its use-side bristle ends on the surface of a configuration plate be brought to concern, the surface of the configuration corresponds to the bristle ends of the bristle bundle on the use side.
  • bristle goods which are used in the field of personal care, for example toothbrushes
  • a method for configuring the bristle ends of bristle bundles on the use side is already known from US Pat. No. 2,488,873, in which each individual bristle bundle is inserted into a correspondingly arranged channel of a carrier, in which it can also be clamped. After loosening the clamp, the bristle bundle is attached receiving carrier created a configuration plate, the surface of which corresponds to the configuration of the bristle bundle or which has a blind hole for the bristle bundle, the bottom surface of which has a depth and shape which corresponds to the desired configuration of the bristle bundle's use-side bristle ends.
  • At least one piston is now attached to a support plate, the length and shape of the free end face of which is precisely matched to the surface or the bottom surface of the blind hole of the configuration plate.
  • the support plate is now moved with its piston toward the carrier, so that the piston penetrates into the channel of the carrier and can move the bundle of bristles or the individual bristles therein until it has rest on the surface of the configuration plate or on the bottom surface of the blind hole.
  • a predetermined configuration of the bristle bundle or of the bristle ends of the bristle bundle on the use side is thereby achieved.
  • the invention is based on the object of providing a method for configuring the bristle ends on the use side of at least one bristle bundle in the manufacture of bristle products, in particular toothbrushes, in which the bristle bundle or the bristle ends on the use side can be configured without a support plate with pistons for moving the bristle bundle or the bristles into the channel of the carrier is required.
  • the bristle bundle with its bristle ends on the use side is brought into contact with the surface of the configuration plate by a compressed gas and / or by vacuum.
  • the previously required support plate with its piston can be omitted. This reduces the manufacturing effort and wear of the corresponding device.
  • the method according to the invention also ensures that no individual bristle-deforming pressure is exerted on the bristle bundle. The wear caused by the support plate with the piston is eliminated.
  • a plate-like carrier 1 which is formed in one piece in the exemplary embodiment shown. If necessary, this carrier 1 can also consist of two plates aligned with one another.
  • a plurality of channels 2 are incorporated into the carrier 1, the number and arrangement of which corresponds exactly to the design of the brush head of a toothbrush.
  • the carrier 1 has only four channels 2 arranged at a distance from one another to simplify the illustration.
  • each channel 2 there is a bundle of bristles 3, which consists of a plurality of bristles 4.
  • the number of bristles 4 in the bristle bundle 3 corresponds to the cross section of the channels 2.
  • bristles 4 of the bristle bundles 3 located in the channels 2 are shown.
  • the length of the bristles 4 or the bristle bundle 3 can correspond exactly to the thickness of the carrier 1 and thus to the length of the channels 2.
  • the bristles 4 are all the same are long, but longer than the channels 2. All bristles 4 assume such a position that all end faces or ends of the bristles 4 are in one plane.
  • the ends 5 of all bristles 4 on the use side are rounded, while the other ends 6 have a flat cutting surface running perpendicular to the bristle axis.
  • a housing 7, which has a chamber 8, is now brought into sealing contact with the side surface of the carrier 1 facing the flat ends 6.
  • An opening 9 opens into this chamber 8, to which a known compressed air line, not shown, is connected.
  • each blind hole 11 has a different depth.
  • the bottom surface 12 of each blind hole 11 is shaped differently. This bottom surface 12 can be concave, convex, arch-shaped and a straight or inclined plane. The depth of the blind holes 11 and the shape of the bottom surface 12 correspond exactly to the desired configuration of the individual bristle bundles 3.
  • the chamber 8 is pressurized with compressed air at a pressure of about 2-6 bar, advantageously at 5 cash, applied.
  • the bristle bundles 4 are treated further in the usual way. This can be done in such a way that the bristles 4 of each bundle of bristles 3 are melted to a thickening at their fastening-side ends, which serve in a further operation for fastening the bundles of bristles 3 in a bristle carrier.
  • the exemplary embodiment in FIG. 2 largely corresponds to the exemplary embodiment in FIG. 1.
  • the blind holes of the configuration plate 10 are initially formed as continuous bores 13, into which plugs 14 are then inserted, so that blind holes 11 are created again.
  • the plugs 14 have an end face at their inner end which corresponds exactly to the bottom surfaces 12 of the blind holes 11 according to FIG. 1.
  • the plugs 14 are made of a sintered metal and have continuous pores.
  • the configuration plate 10 is now assigned a chamber 15, which is provided with an opening 16. Vacuum can be applied to chamber 15 via this opening 16.
  • the configuration plate 10 now rests on the carrier 1 and a vacuum has been built up in the chamber 15, the bristles 4 are drawn against the bottom surfaces 12 of the blind holes 11, so that a configuration of the use-side bristle ends 5 of the bristle bundles 3 is also created by vacuum is possible.
  • the porous plugs 14 can also be replaced by channels or the like. In this case, however, it must be ensured that individual bristles 4 cannot be drawn into these channels. It is also possible that a configuration plate 10 is used which does not have any blind holes 11 corresponding to the arrangement of the bristle bundles 3. In order nevertheless to enable the bristles 4 of the individual bristle bundles to be configured, it is sufficient if the surface of the configuration plate 10 is shaped or configured in accordance with the bottom surfaces 12 of the blind holes 11. Finally, it is also possible to configure the bristles 4 of the individual bristle bundles 3 by a combination of compressed gas and vacuum.
