Definitions

  • the present invention relates to a method for producing bristles from plastic brushes, in particular hairbrushes, or bristle carriers for such brushes according to the preamble of claim 1 and to brushes or bristle carriers produced by this method.
  • GB-A-1076967 has made known bristles with a core and a different colored outer layer surrounding it. By removing the outer layer at the bristle ends, the different colored core is exposed.
  • the object of the invention is to provide a method of the type mentioned at the beginning which allows the bristles to be provided in a simple manner with a head part which can no longer be detached from the bristles and at the same time and without additional effort the bristles together with the head parts have an aesthetically pleasing effect to rent.
  • the head parts can be attached to the bristle ends in a simple manner and without great additional effort, for example by moving the bristles past a heat source relative to the latter .
  • the head parts formed from the bristle material itself are permanently connected to the bristles and can no longer detach from them unless the end of the bristles is broken off. Since the bristles are two-colored, the head part that forms when the bristle ends soften or melt differs in color from the bristle. An additional process step to achieve such a color effect is therefore not necessary.
  • the brushes or bristle carriers produced by this method are distinguished by the features of claims 7 and 8.
  • the hairbrush 1 shown in FIG. 1 has a brush body 2 with a handle 3.
  • a bristle carrier 4 is inserted into a cavity in the brush body 2 and is provided with protruding bristles 5 made of plastic.
  • the bristle carrier 5 is formed by a plate made of a flexible material, preferably rubber, into which the bristles 5 are inserted in a manner known per se.
  • the pin-like bristles 5 are provided at their free end with a head part 6 which is formed in one piece with the associated bristle 5.
  • the head parts 6 have an essentially spherical shape and have a diameter which is larger than the diameter of the cylindrical bristles 5, as can be seen particularly clearly from FIG.
  • the bristles 5 have a core 7, which is surrounded by an outer layer 8, which is of a different color than the core 7.
  • the core is brown
  • the outer layer 8 is black
  • Such a bristle 5 can be produced, for example, by coloring the brown core 7 black on its outside.
  • the head parts 6 are formed by exposing the bristle ends to heat. The outer layer 8 melts away at the bristle end, with the result that the head parts 6 have a color which essentially corresponds to the color of the core 7. For example, with a brown core 7 and a black outer layer 8, a head part 6 of brownish color is obtained.
  • the color transition from the outer layer 8 of the bristle 5 to the head part 6 takes place in the transition area designated by 9 in FIG.
  • the bristle carriers 4, which are equipped with bristles 5 in a manner known per se, are moved past a heat source in the direction of arrow A at a substantially constant conveying speed by means of a conveyor belt 10.
  • this heat source is a Gas burner 11.
  • burner nozzle 11 a is directed against the bristle carrier 4 together with bristles 5 which are moved towards the burner 11, so that these bristles run towards the end 12 a of the open flame 12.
  • the axis of the burner nozzle 11a and thus also the flame 12 run essentially parallel to the direction of movement A of the bristle carrier 4 together with the bristles 5.
  • the bristles 5 which are passed under the flame 12 at a constant speed are heated at their free ends to the softening or melting point of the bristle material.
  • the substantially spherical head parts 6 are formed from the bristle material. Since the outer layer 8 melts away at the bristle ends and thus the core 7 is exposed, the head parts 6 are given a color which essentially corresponds to the color of the core 7. Behind the burner 11, the bristle ends together with the head parts 6 are cooled again by the ambient air.
  • the size and shape of the head parts 6 can be influenced by appropriate adjustment of the flame 12 and suitable selection of the conveying speed of bristle carrier 4 including bristles 5. It goes without saying that for the perfect formation of the head parts 6 the bristles 5 must consist of a suitable plastic material, e.g. made of "nylon 6/6".
  • the formation of the head parts 6 can be carried out in a simple manner, without the need for considerable time and equipment. Since the head parts 6 are formed from the material of the bristles 5 and thus consist of one piece with the latter, a permanent connection between the head part 6 and the bristle 5 is ensured. Through the use of two-color bristles, the head parts 6 receive a color in the course of their manufacture that is different from the color of the outside of the bristles 5. An aesthetically pleasing color effect is thus achieved without additional measures.
  • two-colored bristles 5 can also be used, the color appearance of which is different from that described and which e.g. have a white core 7.
  • the head parts 6 are given a different color, so that bristles with a different color appearance can be obtained without difficulty. In this sense, it is also possible to use both two-color bristles and single-color bristles for the same brush.
  • the head parts 6 are formed with bristles 5 attached to a bristle carrier 4.
  • This bristle carrier 4 together with bristles 5 is then inserted into the brush body 2 in a manner known per se.
