Definitions

  • the present invention concerns important improvements in the weft carrying grippers for shuttleless weaving looms, namely in those members by which the weft yarns are inserted at one end of the Loom and are carried to the opposite end thereof through the warp shed.
  • the present invention faces the problem of constructing the members carrying the weft yarn through the shed in a fully original way, by taking advantage of the positive aspects of the specific characteristics of the two types of grippers known so far, while eliminating the defects of both.
  • each gripper is formed of a composite structure consisting of two metal sheLLs, stiffly connected with a central body of synthetic plastic material, wherein said metal shells are partially incorporated.
  • said shells are provided with hooks, projections, recesses, or Like, for anchorage to the central body of plastic material.
  • the carrying gripper P is shown to be formed of a lower metal shell 1, having a V-shaped section with the sides joining into a single element 2 at the front and parting into two ears 3 rearwardly, of a central body 4 of synthetic plastic material, and of an upper metal shell 5, in the form of a warp guard for the body 4 and having a front hook end 6 and a rear forked end 7.
  • the gripper P has its structure formed by the stiff connection - obtained by injection molding of the body 4 between the metal sheLLs 1 and 5 - of the three component elements. Thanks to the shape of the ends of the shells 1 and 5, and to the presence therein of other coupling elements, as recesses 8 or projections, the connection between said elements is most efficiently achieved.
  • the shells 1 and 5 are moreover substantially incorporated into the central body 4 and, once assembled, the structure of the gripper appears as a very compact unit.
