Definitions

  • This invention relates to a device for guiding a fine wire and for bringing the end of a fine metal wire into the vicinity of an intensely heated body, especially an apparatus for carrying out a metal vapour coating process by vaporisation of the said wire.
  • the wire used necessarily very fine (a few tenths of a millimetre in diameter) curves if it is in a horizontal or inclined position and has to be guided to the vicinity of the heating radiator.
  • This guiding is preferably effected by means of a fine tube into which the wire enters through an orifice on issuing from a delivery reel, pressure being applied by a roller-type driving device, from which the wire issues through another orifice, at a distance of about 10 to 20 mm. from the heating radiator, in the form of a bar, for example of boron nitride.
  • the wire is guided by an assembly of at least two rotary discs which partly overlap one another, defining an orifice which is fixed in space with mobile edges, through which the wire can pass.
  • FIGURE 1 is a perspective view showing the basic arrangement of a system for guiding wire by using two discs.
  • FIGURE 2 is a perspective view in exploded form showing a three-disc wire guiding device.
  • FIGURE 1 two identical discs 12, 14, with parallel axes, are provided, each with a slot of circular form at 13, 15 respectively. These discs partly overlap, the illustration showing the disc 12 in front of the disc 14.
  • the distance between the opposite faces is preferably about several tenths of a millimetre.
  • the positions of the discs relatively to one another are chosen so as to bring the two slots 13, 15 opposite one another over part of their angular development.
  • the zone of intersection is bounded by four equal curved sides.
  • a driving device causes the two discs to receive a rotational movement, for example, as indicated by the arrows f f respectively.
  • a fixed shield in which a through hole 17 is formed is situated in front of the discs.
  • the rotational speed of the discs is regulated so as to permit continuous operation as long as a metal vapour coating operation lasts, for example about an hour and a half.
  • the edges of the slots are protected by the shield to prevent the formation of a deposit which might cause blockage.
  • FIGURE 2 which shows only the necessary elements for the understanding of the invention
  • a fine wire 21 is unwound from a delivery reel 31, mounted on a shaft 30, for example by a clamping effect between a roller 32 driven on its shaft 33 by a device (not shown) and another roller 34 on shaft 35.
  • the wire 21 passes through a hollow shaft 36 which is driven in rotational movement about its axis by means of a gear rim 37 by a device (not shown).
  • another gear rim 40 acts on three gearwheels 41, 42, 43 which are uniformly distributed over the periphery of the rim 40.
  • Each gearwheel comprises a shaft 511, 52, 53 respectively which are each fast with a disc 71, 72, 73 respectively.
  • Each disc is advantageously constituted by a metallic hub or central portion 81, 82,. 83 respectively and a peripheral web 61, 62, 63 respectively which can advantageously be made of polytetrafluorethylene (registered trademark Tefion).
  • Tefion polytetrafluorethylene
  • the hollow shaft 36 can be fixed and serves as a fixed support for the gearwheel 40 which in this case is driven by other means.
  • edges of the three webs define an equilateral triangle with curved sides indicated at 90, through which the wire 21 passes.
  • a shield which may be advantageously be constituted by a metal disc 38 whose periphery is in close thermal contact, for example by brazing, with a tube 39 of annular form connected at its ends 44, 45 to a cold water circulation system.
  • the shield 38 also comprises a hole 91 centrally for the passage of the wire.
  • Device for guiding a fine wire comprising at least two rotatable discs which partly overlap one another, said discs defining an orifice which is fixed in space, with mobile edges, through which the wire passes.
  • each disc comprises a central portion which is preferably metallic, and a peripheral web made of a plastic material.
  • the guiding device of claim 1 further including a hollow rotating shaft through which the wire passes, a gear rim carried thereby, identical gearwheels operatively coupled thereto, and means coupling said discs which form said orifice to said gearwheels to rotate.
  • the guiding device of claim 1 further including a heat shield comprising a disc with cooling means, the centre of said wire passing therethrough.
  • cooling means comprises a tube brazed to the periphery of said heat shield disc and carrying liquid coolant.
