ABSTRACT:
The present invention concerns improved methods and apparatus for forming undulated wire coils that are placed into the cores of dynamo electric machine components. In particular, the invention concerns improved methods and apparatus for controlling the direction of deposit (along the axis about which the coil is wound) for the turns of a wire coil and for positioning the leads of the coil. This is accomplished by forming a series of wire coils using a programmable apparatus that controls a sequence of directions (along the coil axis) in which the wire turns are deposited, as well as positions of the final leads. The same methods and apparatus may also be used to form continuously wound wire portions.
