<p>An edgewise winding apparatus is arranged to produce a coil by winding a wire. The coil includes a plurality of bent portions having equal bending angles and unbent portions each existing between the bent portions. The apparatus includes a holding shaft which will contact with an inner periphery surface of a flat wire and clamp one of the bent portions in a thickness direction of the flat wire and bending jigs which will contact with an outer periphery surface of the flat wire and rotate while pressing the flat wire in cooperation with the holding shaft to bend the flat wire to form the bent portion. The bending jigs are configured to move forward and backward in a lamination direction of the flat wire. The bending jigs are arranged in number equal to the number of bent portions or unbent portions of the coil so that the bending jigs are placed at equal angular intervals around the holding shaft so as to rotate around the holding shaft.</p> |
