Definitions

  • This invention relates to a weaving heddle for ridermovable weaving shaft or machine with hook-formed ends to assemble the heddles on the shaft or track and assembled removably on the assembly track.
  • the heddles In order to provide the necessary play and spacing on the assembly track for satisfactory or perfect weaving, the heddles must have the possibility to easily move in a vertical direction for a short distance and at the same time must be held on the assembly track, which can be accomplished providing a projecting attachment nose on one or the other side of the elongated hole or perforation in the heddle.
  • the invention consists essentially therein that closed back part on the ends of the weaving heddles each shall have a longitudinal recess, the length being greater than the length of a rib on the end of the track on which the heddles are hooked.
  • the rib together with an abutment in the slot as to the vertical play or movement of the heddles, will limit the movement of the heddles and thus prevent the falling off of the heddles from the track.
  • the receiving track must be provided with a longitudinal groove in which the heddles can move vertically.
  • This receiving track must be at least so thickly dimensioned that the groove can be applied without influencing the stability of the track. Greater dimensions will result in higher weight and since in a weaving frame the smallest weight saving is of value, the invention presents an essential advantage by having a low weight for the track since the form of the weaving heddles, the receiving track must only be thickened Where the heddles hang over the longitudinal edge.
  • a lateral curvature or vaulting in both or only in one direction is provided at the closed or open side of the hook part of each heddle. This curvature serves the purpose to provide a stable mounting for the heddles on the track.
  • FIGURE 1 is a side elevation partly in section showing an end of a heddle on an assembly track
  • FIG. 2 is a side view of a heddle on its track showing an outwardly curved hook end
  • the weaving heddle 10 On its end the weaving heddle 10 is provided with a hook 10a, 10b. At the closed hook part 1001, of the heddle 10 there is formed a recess 11 which has a stop or abutment 12 and at the other end there is provided a bent part to form an open hook part 10b to over grip the upper part of the string track 16.
  • the hook part 10a as well as the hook part 10b may have either a projecting curvature or vault-like portion 15, FIG. 2, or double counter-directed curvatures 17, FIG. 3, which provides a stable reinforcement for the heddle 10 on the receiving track 16.
  • the hook part 10b as in FIG. 1 is curved or concave-convex as shown at 15 as viewed in end elevation, and as to FIG. 3 the hook part 10]; is straight but the hook part 10a, 10 as in FIG. 1 is reversed curved with two curved or concavoconvex portions 17 as viewed in end elevation.
  • Rider-free weaving heddle for a track member having a single projecting rib portion on an end side thereof where the heddle is supported comprising a hook-shaped end which is J-shaped and having a back part and a front part forming a recess between them, said back part having an abutment at a lower end of the recess to cooperate with the rib portion of the track member which latter projects into the recess, said rib portion having a counter stop to cooperate with the abutment in the heddle and the recess in the heddle being of greater length than the rib portion on the track member.
  • a loom harness comprising a rectangular frame with upper and lower staves arranged in spaced relation, riderless heddle carrying tracks supported by each of said staves, and a plurality of heddles supported between said heddle carrying tracks, each of said heddles having a pair of hook-shaped end portions embracing said heddle carrying tracks, said hook-shaped end portions each having a back part and a front part forming an opening between them, said front part being shorter than said back part in the longitudinal direction of the heddle, each of said heddle carrying tracks having a single longitudinal rib portion projecting towards said back part of the hook-shaped end portions of the heddles and being arranged along one edge of the heddle carrying tracks, said edge being turned away from the other one of said tracks, said back part of the hook-shaped end portions of the heddles having a recess for receiving said rib portion of the heddle carrying tracks, said recess being placed opposite said front part of the hook-shaped end portions and having a width, measured
