ABSTRACT:
Methods and apparatus are disclosed for producing dynamoelectric machine coil groups or winding poles. A clamp device, relatively axially movable coil form and turn receiver, and relatively rotatable flyer are used, and interpole wire segments are established by intercepting, at a fixed location, a segment of wire extending between the form and flyer prior to complete cessation of relative rotation between the same.
Intercoil winding segments are also accurately established. For example, an intercoil winding segment is deflected out of the winding plane and in a direction toward a subsequent winding form stage during the development of the last turn of a coil developed on the previous winding stage. Deflection of the intercoil winding segment is preferably accomplished substantially concurrently with advancement of the winding form relative to the turn receiver. In one form, a inclined ramp is moved into the winding plane and into interfering relation with an intercoil winding segment as the winding segment is being developed and as a subsequent winding stage is being moved into the winding plane.
