Definitions

  • the present invention relates to an apparatus for making rotary-brush bristle assemblies; according to another aspect thereof, the invention relates to a method for making the mentioned rotary-brush bristle assemblies.
  • rotary brushes including bristles formed by a given preset number of bristle yarns is mainly due to the fact that the bristles must be evenly distributed on the brush surface in order to prevent said brush from vibrating as it is turned and in order to provide a perfectly balanced rotary brush.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing an apparatus which is adapted to automatically accurately count the bristle yarns.
  • a main object of the present invention is to provide such an apparatus which can be quickly and easily fitted downstream of the bristle yarn extruding assembly, without the need of performing substantial modifications to this extruding assembly.
  • Another object of the present invention is to provide such an apparatus which is very reliably and safe in operation and can be easily constructed starting from easily available elements and materials and which, moreover, is very competitive from a mere economic standpoint.
  • a bristle yarn counting apparatus for accurately counting the bristle yarn to be used for making rotary-brush bristle assemblies, characterized in that said apparatus comprises, downstream of a bristle yarn extruding assembly, a bristle yarn drawing and guiding assembly adapted to supply with a set number of bristle yarns a bristle yarn bundling assembly, adapted to associate the bristle yarns with one another by means of an outer wrapped thread so as to form a bristle yarn bundle holding a set number of bristle yarns, downstream of said bristle yarn bundling assembly there being moreover provided a reeling frame adapted to form a bristle yarn hank.
  • the apparatus for making rotary-brush bristle assemblies comprises, downstream of an extruding assembly, of a substantially known type and which is not shown in the drawings, a conventional bristle yarn drawing assembly, indicated overally at the reference number 1, which supplies with extruded and drawn bristle yarns a guide assembly 2, including a plurality of guiding pulleys 3 which are so arranged as to properly drive a set number of bristle yarns which have been subdivided after the bristle yarn drawing step.
  • the bristle yarns are then supplied to a bristle yarn bundling assembly, indicated overally at the reference number 10, comprising a guide tube 11 there-through the yarn material is caused to pass, and supporting a binding-thread bobbin 12 of an assembling yarn 13.
  • the thread bobbin 12 is coupled to an electric motor 15 which, by means of warm screw transmission elements 16 causes said thread bobbin 12 to turn about its axis so that the assembling or binding thread 13 is wrapped about the yarns 5 to provide a yarn bundle containing a set number of yarns.
  • the assembling thread 13, supplied from the thread bobbin 12, is driven inside an yarn guiding element 17, into which there is introduced the yarn 5 assembly coaxially supplied to the assembling thread 13 bobbin 12.
  • the thus made yarn bundles are wound on a reeling frame, overally indicated at the reference number 20, which is operated to provide a yarn assembly hank holding a set number of yarn bundles which, in turn, hold a set number of individual yarns.
  • This hank which is made with an easily controllable turn numbers, is then cut so as to provide a bundle of yarn assemblies which is wrapped in by a tape material so as to provide a stable bundle.
  • the thus made bundle is then properly cut to given desired lengths.
  • the invention provides a method in which, by counting the yarns immediately downstream of the drawing step, it is possible to obtain an end product including an already known yarn count, thereby the bristles can be made according to a pre-set yarn number, so as to provide perfectly balanced rotary brushes.
