Abstract: Apparatus involves advancing wedge material stock and also substantially permanently forming the stock material to precise dimensional tolerances by squeezing and deforming the material with pinch rollers. Deforming of the material includes pinching the material and thereby reducing the thickness of the material at preselected locations, with the reduced thickness portions of the material establishing precise dimensional tolerances of wedges produced by the process. A wedge magazine comprises the lower tooling of a coil injection machine and forms, in effect, an extension of tool gaps that accommodate winding coils in a coil injection machine. The magazine receiving the wedges may be a short term storage magazine which in turn feeds the wedges to a wedge magazine that forms the lower tooling of a coil injection machine.

Abstract: Methods and apparatus for selecting increments of relative travel of portions of at least one coil insertion apparatus in response to the actual height of a selected magnetic core and interdependently adjusting the mechanical interrelationships between two or more parts of winding turn establishing means of winding apparatus so as to provide one or more turns of conductive material having a size and shape that is particularly adapted for placement in slots of the selected magnetic core. During the interdependent adjustment, one or more additional coil insertion apparatus may be interdependently adjusted. In one approach, a gauge measures actual axial length of core and mechanism concurrently sets up winding size determining means. The gauge may be coil insertion apparatus.
