ABSTRACT:
A method of continuouly forming edgewise wound cores from a continuous lanced strip of a ferromagnetic material having a pair of opposite faces interposed between a pair of opposite edges at least in part extending lengthwise of the lanced strip. In practicing this method, the lanced strip is continuously drawn through a bending zone in which at least the opposite edges are constrained, and the lanced strip is continuously deformed generally edgewise thereof about an axis of the bending zone so as to continuously from a plurality of helical convolutions. At least as the lanced strip travels beyond the bending zone, the lanced strip is pressed against a rotatable surface to effect the continuous drawing of the lanced strip through the bending zone.
A core, a lanced strip, and apparatus are also disclosed.
