ABSTRACT:
A process and device for forming the winding core of a stator or rotor. The winding core is only partially exposed to shaping pressure. Shaping is then continued progressively over the core periphery. A device for effecting the method includes a single or multipartite pressing tool for the winding core. The tool is rotatable relative to the long axis of a stator or rotor. In a preferred embodiment, the tool has a narrow shaping part positioned adjacent to a wrapping tool used to provide a wrapping about the shaped coil.
