Definitions

  • the present invention concerne a gripper strap, of the type used to move the weft fooding grippers along the shod of shuttleless looms.
  • the present invention supplies a gripper strap according to the claim.
  • Said end element of the strap according to the invention is engaged with the rest of the strap by a free fit and is romovably fixed thereto by way of the gripper and together therewith.
  • the end 1 of the strap according to the invention - shaped so as to allow mounting thereon the front part of a weft feeding gripper - is separate from the rest of the strap 2.
  • Said strap end 1 is provided with a seat 3, into which is meant to fit the profiled end section 4 of the rest of the strap 2.
  • said section 4 has a shape mating with that of the seal 3, with corresponding semicircular ends 4A and 3A respectively.
  • the strap end 1 is made of stiff and highly wearproof material and is thus apt to move efficiently and for a long time, without creating any problems, into the elements guiding it along the shed.
  • the remaining part of the strap 2 is made of highly flexible material, allowing it to be deformed to the extent required for its winding around the goar wheels provided for its reciprocating motion.
  • a plurality of screws 7 (figs. 6 and 7) arc provided to fix the strap end 1 to the rest of the strap 2, when these two parts are reciprocally engaged by a free fit as shown in fig. 2, said screws crossing holes and/or corresponding notches, 5 and 6 respectively, formed in the two strap parts (fig. 1).
  • the illustrated embodiment provides for through holes and notches 5 and 6, and the screws 7 screw simultaneously into threaded seate of the gripper 8, whereby the fixing between the two freely engaged strap parts 1 and 2 is obtained by way of the gripper itself.
  • the holes 5 of the strap end 1 are also provided with countersinks 9 to house the honds of the screws 7.
  • the strap end 1 can be easily replaced when starting to gel worn: in this case, it is sufficient to looson the screws 7, to remove the gripper 8 from the strap parts 1, 2, and to then connect again the gripper to the strap formed by a new end part 1 and by the rest of the strap 2 already in use.
  • the operation is simple and very quick, and it allows to dispose, at a reduced cost, of a practically new strap.
  • the life of a gripper strap according to the invention is in any case longer than that of the conventional straps, even without replacing the strap end 1, due to the advantages - as far as flexibility and wear - guaranteed by the rational choice of the materials used for the two parts 1 and 2 forming the strap.
