Abstract
A method for forming an edgewise wound core from a lanced strip of generally thin ferromagnetic material. The lanced strip includes a pair of sets of segments extending generally lengthwise thereof with the segments of one of the segment sets being integrally interposed between the segments of the other of the segment sets, and a set of salient pole teeth are integral with the segments of the one segment set extending generally laterally therefrom. In practicing this method, successive segments of the other segment set are successively and independently edgewise constrained, and the salient pole teeth and segments of the one segment set are unconstrained. Only the edgewise constrained segments of the other segment set are edgewise deformed, and the unconstrained salient pole teeth and segments of the one segment set are maintained in their original lanced configurations. A method of operating apparatus for continuously forming edgewise wound cores is also disclosed.
