Disclosed is a controller drum (1) made of plastic, the individual elements (3) of which have lateral faces (4, 5). These lateral faces (4, 5) form matching pairs, each of which establishes an engagement slot (6). The individual elements (3) have a radial centering collar (7). At each interface (8) of the elements (3) there are three true-fitting axial contact faces (9). The centering collar (7) ensures the concentricity of the individual members of the controller drum. The engagement fork to the controller drum is made of plastic or a plastic-metal element, with pins or rollers that engage with the controller drum.
