ABSTRACT:
Method and apparatus for forming a multi-pole winding for a dynamo-electric machine wherein a skein of magnet wire is wound and mounted on spaced retaining jaws biased outwardly to keep the wire under light tension during a subsequent forming process. Forming tools are moved inwardly against the wire between the retaining jaws to produce a petalled, serpentine form with a series of apices between the retaining jaws. Holding pins are inserted between the wire and the forming tools at the apices, and the forming tools are retracted. While the wire is held between the retaining jaws and holding pins, it is loaded onto a fingered transfer tool.
