Definitions

  • the invention relates to a device for forming a leno selvedge consisting of mutually moving heald frames, a thread guide device being attached to one heald frame and a needle holder having two parallel, essentially U-shaped frame rails, which holding a thread guide element, is arranged on the other heald frame.
  • a device of the type mentioned is known for example from German utility model 79 31 872. It has been shown that these frame rails are subject to high wear, especially when the magnets arranged in the thread guide element come into direct contact with the frame rail. If the frame rails of a needle holder are worn out to such an extent that the thread guide element is no longer properly guided, so that there is a risk of binding errors, the entire needle holder must be replaced, which is expensive.
  • a leno device is known with a guide frame which guides a warp thread holder in the frame rails, a thread guide device being guided in the parallel frame rails.
  • a guide frame which guides a warp thread holder in the frame rails
  • a thread guide device being guided in the parallel frame rails.
  • needle bearing strips are provided in the end faces of the rails. The wear problem is solved by the arrangement of needle bearing strips, which have low friction.
  • the invention has for its object to provide a needle holder in which the wear problem is solved with simpler means.
  • a groove is arranged in each leg base of one leg of the U-shaped frame rail, which is used to receive and guide the metal rail.
  • frame rails made of plastic could not be used.
  • a frame rail made of plastic can now also be used; the magnetic braking of the thread guide element now takes place in cooperation with the metal rail.
  • Frame rails made of plastic have the advantage of lower weight, which opens up the possibility of increasing the number of strokes of a weaving machine.
  • Metal rails which according to the prior art are only nickel-plated for protection against rust, also have the disadvantage that they quickly become rusty when used in wet weaving. This is impossible with plastic frame rails.
  • the metal rail itself is made of rustproof but magnetic steel.
  • a device for forming a leno selvedge consists of reciprocating heald frames, a needle holder being arranged on one heald frame and the other heald frame having a thread guiding device.
  • the second heald frame with the thread guide device arranged thereon has been omitted in FIG. 1.
  • the needle holder designated as a whole by 1, is arranged on the heald frame 2.
  • the needle holder 1 consists of the two parallel frame rails 3 and 4, which serve to guide the thread guide element 5 (FIG. 2).
  • the substantially U-shaped frame rail 3, 4 has a groove 6 and 7 in the leg base of each leg.
  • the metal rails 8 and 9 are located in the grooves 6 and 7 respectively.
  • the thread guide element 5 guided in the two frame rails 3, 4 is therefore not in direct contact with the frame rails, but is in contact with the metal rails 8, 9 on both sides. If the metal rails are worn, they can easily be replaced with new ones.
