Definitions

  • each heddle 22 is provided at each end with a C-shaped hook member 23.
  • These C-shaped hook members 23 each provide an opening 23a which is somewhat higher than the respective heddle guide rail 20 or 21, so that such hooks can be slipped or pushed over the legs 24 or 25 and onto the corresponding heddle guide rails 20 or 21, respectively, when such C-shaped hooks 23 are located in inclined position, as clearly shown in FIGURE 6.
  • This opening 23a of each hook member 23, however, is not so large that these hook members, once they have been pushed-on and have assumed a vertical position, can slide past the upright projections or projecting means 24 and 25 extending in the same direction.
  • the corresponding mouth 23b of each associated opening 23a is advantageously wide enough to permit displacing of each heddle hook member 23 past the bolts 19.
  • harnesses which, as shown in FIGURE 5, are arranged side-by-side and in tandem with each such harness 18, 18a being supported and individually driven by a drive rod 10.
  • the harnesses arranged side-by-side will hereinafter be designated as a row, and those arranged in tandem will be designated as a group.
  • the drive rods 18 for the harnesses 18 or 18a of each group, in accordance with the spacing of such harnesses are offset forwardly and rearwardly, and in consideration of their driving mechanism are also laterally oifset.
  • the harnesses 18 and 18a support one another in the One direction, and due to the mutual engagement over one another of the upper projections or projecting means 24 such harnesses support their heddle guide rails 20 in the opposite direction from excessive bending towards the front or rear under the effect of the forces transmitted through the warp threads.
