摘要

The device has a fixed element (2), mobile driving element (1) and mobile driven element (4) which are respectively equipped with cams, where the mobile elements are moved in rotation. A cylindrical mobile element (3) i.e. slide, is moved in transverse translation with respect to a rotation axis. The cam of the driving element actuates the cylindrical element (3) and pushes the cam of the driven element at speed and angle different from the cam of the driving element.
