(54) Mechanism for actuating the sley and the belts of grippers in a weaving loom


(57) In a mechanism for actuating the sley (7) and the belts (N) of grippers (Z) in weaving looms, the continuous rotary movement of the main axis (A) of the loom is transferred, by means of an angular transmission comprising a bevel gear pair (2), to a secondary shaft (1) which is perpendicular thereto. A pair of conjugate radial cams (3) is keyed onto the secondary shaft (1) and causes, by means of an associated rocker arm (9), the movement of the gear wheel (D) driving the belts (N) of the grippers (Z). A spherical cam (4) is also axially mounted on the free end of said secondary shaft (1), said cam actuating a rocker arm (6), the fulcrum of which is directly connected to the shaft of the sley (7).
