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.
  • One such gripper does include a metal part rigidly connected to the body of plastics material.
  • the metal part is intended to promote engagement of the weft yarn, and does not stiffen the gripper body.
  • 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, at least one of the shells extending substantially over the whole length of the gripper body.
  • 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 couplings 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.
  • the drawing gripper T of figure 2 which is formed of a lower metal shell 9, having a shape which is fairly similar to that of the shell 1 of the carrying gripper P, of a central body 10 of synthetic plastic material, and of an upper shell 11, comprising a frame portion 12 and an extension or tail 13 ending with ears 14.
