Definitions

  • the invention relates to a heald frame device suitable for achieving a leno selvedge with lifting strands attached to opposing heddle support rails and a half heddle which is attached to a half shaft which is mutually controlled by the heddle support rails (see AT-A-141409).
  • a heald frame suitable for a leno selvedge is known to consist of two lifting shafts equipped with heddle support rails, which alternately, i.e. back and forth, are moved, and the associated half shaft.
  • the lifting strands, which guide the upright threads, are lined up on the heddle support rails.
  • the half strand, which guides the leno thread, is pushed onto the half shaft. Since the half shaft is controlled by the heddle support rail, reversal of the movement of the half heddles takes place in the crossing position of the opposing heddle support rails, so that the half heddles only carry out half a stroke in comparison to the heddle support rail. As a result, the leno thread is alternately lifted into the compartment formed by the upright thread.
  • the control of the half shaft with the attached half heddle is carried out by a so-called leno yoke, which essentially represents a frame which is in contact with the heddle support rails and is carried by a heddle support rail, whereby a spring is tensioned. If the heddle support rail runs back, the leno yoke remains connected to the heddle support rail, since the leno yoke is under spring tension. In the crossing position of the heddle support rails, the half shaft and thus the half heddles are carried along by the other heddle support rail.
  • the object of the invention is therefore to create a heald frame device which is suitable for a leno selvedge and which avoids these disadvantages.
  • This is achieved according to the invention in that the half shaft is magnetically connected to the heddle support rail.
  • the design is such that the half-shaft has a slide provided with magnets, which is guided on rods which are connected to the synchronous strand support rails.
  • This magnetic connection and the arrangement of the half-shaft on the rods ensure that the half-shaft and thus also the half-strand attached to it are properly guided.
  • any displacement of the half-shaft is possible.
  • the half shaft on the rod is also transported downwards. If the direction of movement of the heddle support rail reverses, then the half-shaft is taken up again as a result of the magnetic connection to the heddle support rail until the other heddle support rail brings about the opposite movement of the half-shaft again.
  • the design according to the invention also ensures that the half shaft, because of the magnetic coupling with the heddle support rails, only runs through half the stroke in comparison to the entire stroke of the heddle support rail. This measure significantly reduces wear on the lifting strands.
  • the heald frame device consists of the two lifting shafts 1 and 2, which perform an opposite movement using known means (not shown).
  • the heddle support rails 3 and 4 are arranged on the lifting shafts and are connected to the lower heddle support rails 3a and 4a by shaft supports (not shown).
  • a half shaft 7 is attached via clamping pieces 10 and 10a.
  • the half shaft 7 has a sliding piece 8 which is guided on the rods 9 and 9a provided with the clamping pieces 10, 10a, which are connected to the heddle support rails.
  • the half-shaft 7 is magnetically connected by the slider 8 to the heddle support rail 4, specifically according to the exemplary embodiment by the clamping piece 10, by incorporating corresponding magnets 11 in the slider 8.
  • the rods can be non-circular.
  • 10 guide means can be provided on the slider 8 and on the opposite clamping piece, which ensure a perfect position of the half-shaft.
  • a wedge 12a can be provided on the slider 8 and a corresponding recess 13 can be provided on the clamping piece 10.
  • the half-shaft 7 also carries out a corresponding alternating movement, so that the half-strand 12, which is attached to the half-shaft, takes the leno thread guided in the half-strand 12 shortly before the closed shed position, which has the consequence that the leno thread is passed once to the left of the upright thread and once to the right of the upright thread, so that a binding is achieved.
