  • Patent number: 4327478
    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.

  • Patent number: 4269235
    Abstract: Method and apparatus for sequentially winding a plurality of windings on a winding form and for transferring the windings sequentially from the winding form to a collecting tool such that the plurality of windings are disposed on a collecting tool for subsequent collection axially through an aperture of a stator sheet packet positioned in adjacency with said collecting tool. In accordance with the invention, during the transition from winding one winding on the form and winding the next winding on the form, the winding wire is held clamped at a point within the peripheral region of the windings disposed on the collecting tool to be drawn through the aperture during subsequent collection.
