Abstract
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. This arrangement offers great simplicity compared to known systems since the forthcoming path of movement of the clamping means is short and simple and because the available relative motion of conventional parts of conventional devices may be utilized to actuate the clamp, thus eliminating the need for a separate drive or control.
