ABSTRACT:
A method of forming an edgewise wound core from a strip of a generally thin metallic material. In this method, a plurality of segments arranged generally in side-by-side relation are formed in the strip along the length thereof, and each segment is freed from an adjacent segment at each of a plurality of reaches thereof along the length of the strip with the segments being supported at junctures disposed between the ends of the reaches. The strip is deformed generally edgewise thereof thereby to form a plurality of convolutions of the strip, and each segment is also deformed edgewise thereof free of the adjacent segments along each of the reaches with the deformed segments being supported at the junctures between the reaches, respectively.
