Definitions

  • This invention relates to important improvements in the means for controlling the reciprocating movement of the weft conveying grippers in shuttleless looms.
  • the present invention now provides an arrangement for controlling the movement of the weft conveying grippers in shuttleless looms, which satisfies the wishes of loom constructors and users in terms of the various listed requirements, and constitutes a modern, rational and satisfactory solution to the stated problems, also when high and very high weaving speeds are involved.
  • the arrangement for controlling the movement of the weft conveying grippers according to the invention is characterised essentially by the fact that it comprises continuous fixed guides extending over a wide arc of the gearwheels along the periphery thereof and at a short distance therefrom, and acting on both lateral portions of the straps in order to keep them in constant and precise engagement with said gearwheels along said arc.
  • the slots in said straps are of elongated rectangular shape, and the teeth of said gearwheels are of a corresponding shape, and have a roundedged periphery.
  • the arrangement according to the invention comprises, on each side of a loom, a gearwheel 1 controlling a strap 2, to impart cn said strap and on the gripper carried thereby the to-and-fro movements which govern the insertion of the weft yarn into the loom shed.
  • the strap 2 comprises at its centre a row of elongated rectangular slots 3, which are different in shape and dimensions from all the slots provided up to date in the straps used for similar purposes, and which are clearly shown in Figures 4 and 5.
  • the strap 2 meshes with the peripheral teeth 4 - of corresponding or complementary shape (see figure 3) - of the gearwheel 1, over a wide arc of which it extends, said teeth being also distinguished by their round-edged periphery.
  • the arc of the gearwheel 1, over which the strap 2 extends, is defined by guides 5 which partly surround the wheel close thereto.
  • the guides 5 are U-shaped so as to act at 6 and 7 on the lateral strap portions to the side of the slots 3, and thereby ensure a continuous and reliable engagement into said slots of the base of the teeth 4, which substantially project from the periphery of the gearwheel 1.
  • the thorough engagement of the gearwheel teeth 4 into the strap slots 3 - made precise by the shape of the teeth and slots, and made continuous and accurate by the presence and configuration of the guides 5 - determines the mutual positioning between the strap and the gearwheels (or overlap) with a precision so far inconceivable, thereby allowing a particularly even distribution of the loads over the teeth and thus less wear, reduced temperatures and less noise.
  • the elongated rectangular shape of the strap slots 3 substantially reduces the bending stresses in the straps and facilitates their deformation when meshing with the gearwheels, with no harmful consequences as far as strength and wear.
  • the straps bend with a greater continuity than those of conventional technique which comprise much smaller and , in particular, less elongated slots).
  • the round-edged periphery of the gearwheel teeth 4 ensures a smooth engagement, with no impact or wear, between the gearwheels 1 and the straps 2.
