Abstract

The invention concerns a rotor-type element (1) designed to co-operate with a stator part, having therefor at least an axis of rotation (A) parallel to the view plane, with respect to which it is adapted to pivot along specific axial positions and having at least a localised permanent polarity adapted to co-operate with at least a drive unit (7a, 7b; A, B, C) of said stator part, said element being divided into at least two angular sectors (1a-1f, 10a-10f) with different main shade and said element being a composite element consisting of a section (10) of wires. The inventive method for making said element consists in assembling the wires in contiguous fashion into a strand of wires, said strand being then cut into sections, each section corresponding to a rotary element.
