Abstract
A wound core is formed by forming a core element having slots for inserting a wire and teeth with equal spaces on one side of a band steel sheet; and winding the core element by engaging pins and applying local stress at the part of the slots to the opposite side to deform the core element to sequentially bend it in a multi-angle structure and to wind it helically.
