<p>A device capable of converting a continuous rotary motion into a reciprocating rotary motion, in particular for controlling the translation of a weft thread picking gripper in a textile loom where the axes of the two motions are perpendicular one to the other and lying in one and the same plane, comprises a spherical cam (21) having two complementary profiles, the cam being driven by the axis having continuous rotary motion; acting respectively on the two complementary profiles are two cam sensors of a lever (28) oscillating about the other axis (29) and thus having reciprocating rotary motion.</p> |
