The control unit has two cam tracks on a single rigid assembly (5) to provide a relative displacement of a follower moving between two different positions. The rigid assembly consists of sections (12 - 15) with the cam tracks and intermediate sections (16, 19); it is basically trough-shaped, with a base and two side walls with the cam tracks, and it can be fixed, with the follower having a roller on a moving axle (2). Alternatively, the cam tracks can be mobile and the roller mounted on a fixed axle. |
