Definitions
- the invention relates to an arrangement for controlling the movement of the weft conveying gripper in shuttleless looms, of the type using a pair of gearwheels which perform short reciprocating rotations at the loom shed ends, and a pair of gripper advancement straps having longitudinally aligned central slots meshing with the teeth of said gearwheels.
- the DE-B 20 20 765 discloses an arrangement, in which the strap having longitudinally extending slots positioned at close distance is laid around a wheel without special guide for the strap.
- this object is solved in that the arrangement comprises continuous fixed guides extending over a wide arc of the gearwheels along the periphery thereof and acting on both lateral portions of the outside surface only of the respective strap whereby the latter is held in constant and precise engagement with said gearwheels along said arc.
- the arrangement according to the invention comprises, on each side of a loom, a gearwheel 1 controlling a strap 2, to impart on 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 clearly shown in Figures 4 and 5. Through such slots, 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 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.
