Definitions

  • the present invention relates to an improved device for twisting a wire by double twisting, a device commonly designated by the expression "double twist spindle”, an expression which will be adopted in the description below.
  • the wire of the winding taken in the parade, forms a reeling balloon and is engaged from top to bottom in the fixed hollow axis, passes through the channel of the rotating return member, then into a centering barbin- balloon stop, arranged in the extension of the axis of the spindle, the wire forming the balloon between the peripheral surface of the rotating return member and said barbin and then being returned in a conventional manner.
  • Double twist pins have been known for a long time and have been the subject of numerous publications. notably in French patents 878,641, 885,434, 57,274 (second addition to French patent 955,185), in British patents 618,028 and 989,608, as well as in patents in the United States of America 2,207,574 and 3 640,060.
  • Such a device has numerous advantages and in particular makes it possible to increase the speed of rotation of the spindle for an equivalent tension given to the wire or, to treat fragile wires having to be subjected to low tensions at equal speed. Furthermore, such a device makes it possible to significantly reduce the height of the balloon and consequently the size of the installation.
  • the rotary hollow bowl according to the invention has substantially the shape of a trumpet horn, a megaphone, or the like.
  • the upper end of the hollow bowl according to the invention is advantageously curved inwards, which facilitates the release of the wire during the formation of the balloon.
  • the wire guide channel that the bowl has has a part arranged in the extension of the hollow axis of the winding door assembly and a part preferably arranged orthogonally to the previous one.
  • a deflection element for example made of ceramic, is arranged in the elbow formed by the two parts of the wire guide channel.
  • the double-twist spindle comprises a rotary shaft 1 mounted on the frame 2 of the loom by means of an assembly forming a bush 3.
  • the rotation drive of this shaft 1 is obtained for example by a tangential belt 4.
  • the other end of this shaft 1 is integral with a return magazine member 5, in accordance with the invention, which is in the form of a volume of revolution whose axis coincides with the axis of the shaft 1, and which has a part 6 having the shape of a cone of slight slope, extended by a flared curved part 7 of concave shape.
  • the upper end 8 of this return magazine member is curved and curved inwards.
  • a fixed winding door 9 Inside the rotary reference store member 5 described above is disposed a fixed winding door 9.
  • This winding door is mounted to rotate freely, by means of ball bearings 10-11, relative to the axis 1 and consequently with respect to the rotary store return member.
  • This winding holder 9 is immobilized by any known means, such as for example by magnetic means 21.
  • This winding holder 9 essentially consists of a base 12 on which is fitted the end of the coil supporting the wire to be processed, coil 13 which is not shown in FIG. 1 for the sake of simplification. It also comprises a hollow axis 14, the upper part 15 of which serves as water blocking the torsion imparted to the wire 16.
  • the channel of the hollow axis 14 is arranged in the extension of part 17 of the wire guide channel which comprises the store return member, this guide channel 17 being extended by a part 18 disposed orthogonally to it, a deflection element 19 being disposed at the elbow formed by these two channels 17 and 18.
  • the wire first takes a first twist in its path from its unwinding point to the top 15 of the hollow axis 14, then a second twist in the outer balloon B between its exit of the store reference member and the guide barbin 20.
  • Curves I and II of FIG. 3 appended show that, at 6000 revolutions per minute, a spindle produced in accordance with the invention (curve I) consumes a power of around 13 watts, whereas with a shape magazine bowl tapered (curve II) the power consumption is approximately 15 watts. Furthermore, in both cases, the voltages communicated to the wires were identical.
