Definitions

  • ABSTRACT Card Clothing wire is coated in strand form with a permanent baked on layer of polytetrafluoroethylene.
  • metallic wire for card clothing teeth while in strand form is coated with a permanently applied coating of polytetrafluorethylene release agent.
  • the coating is of a permanent nature, that is to say it is bonded to the teeth in such a manner that it will not easily wear off, and in this sense, the invention is distinguished from the mere treatment of card clothing by the spraying of such release agents as silicone oils.
  • a suitable material for coating the teeth is that sold under the registered trade mark Teflon or Fluon.
  • a strand of metallic wire card clothing is traversed continuously under a spray 12 of pure polytetrafluoroethylene resin, so that it is coated all over with a film of the P.T.F.E. Beyond the spray 12, the wire 10 passes under heaters 14 which bake the P.T.F.E. on to the steel wire which is toothed as shown. The wire can then be wound on to a drum or roller of a carding machine and will function in the conventional manner.
  • the P.T.F.E. coating acts as an anti-friction material relatively to grease, added oil, and like foreign matter, particularly in the grooves between adjacent convolutions of the card clothing wire. It will be appreciated there fore that the invention is of particular significance, in woollen carding, although it is by no means limited in its application to woollen carding machines.
  • the non-stick properties of the P.T.F.E. coating are primarily intended to prevent the accumulation of foreign matter in the card clothing when it is applied to the roller or flats of the carding machine, but it will be appreciated that it might also have some advantageous effect on the carding section of the teeth relatively to the fibres themselves. Therefore, in practice, it might be found necessary to vary the construction of the teeth (in respect of such characteristics as angle of slope of the fronts and backs of the teeth or the pitch of the teeth) in order to obtain a specific carding effect.
  • the strand of metallic wire card clothing is first immersed in a bath of water-based P.T.F.E. resin, so that when the wire is removed from the bath it is covered with a film of the resin before the treatment.
  • the P.T.F.E. coating by preventing contact between the steel wire and the atmosphere, reduces the danger of deleterious corrosion of the wire.
  • a method of treating a strand of card clothing wire in which the wire is coated with polythetrafluoroethylene and the coating is baked by heat treatment so that it becomes secured in a permanent manner on said wire.
  • a method of treating card clothing wire in which a coating of polytetrafluoroethylene is applied to the wire in strand form after the formation of teeth on the wire, and said coating is secured to said wire by baking so that it becomes secured in a permanent manner on said wire.
  • Card clothing which includes carding wire coated in strand form with a permanently applied baked-on layer of polytetrafluoroethylene.
