Definitions

  • the invention relates to a shed-forming module for the selective movement of shed-forming elements using lifting elements, wherein several shed-forming elements, in projection onto a plane perpendicular to their movement direction, are situated next to each other in a first direction and in a second direction perpendicular to the first direction, wherein the shed-forming module comprises the components as described in the preamble of the first claim.
  • a shed-forming module is used more particularly in open-shed jacquard machines with two or more positions.
  • the invention furthermore relates to a weaving machine provided with such a shed-forming module or a jacquard machine provided with such a shed-forming module.
  • the warp threads are positioned during the successive weaving cycles with respect to the level at which a weft thread is introduced in each cycle.
  • the positions of the warp threads in the successive weaving cycles are in this case determined in such a manner that the weaving process results in a fabric with a predetermined weaving pattern.
  • This positioning of the warp threads with respect to the weft insertion level on a weaving machine, known as shed forming, is realized automatically by means of a shed-forming device or shed-forming module.
  • the known shed-forming device comprises one or more selection systems which are provided to select or not select one or more hooks.
  • a hook is selectively carried or not carried by a lifting element which is movable in the vertical direction and forms part of a set of lifting elements consisting of at least two lifting elements which move up and down in pairs in antiphase.
  • These lifting elements are driven in an up and down movement in antiphase with respect to each other, according to an adjustable amplitude, via lifting means such as for example knife grids.
  • a shed-forming device comprises at least two sets of knife grids moving up and down, for example on two opposite sides of the shed-forming device.
