Patent ID: 10819199

Abstract:
A winding apparatus 23 forms a rectangle-tubular edgewise coil 1 by alternately repeating bending of a rectangular conductor 2 in a clockwise direction in a plan view in an edgewise manner and feeding of the rectangular conductor 2. The winding apparatus 23 includes a bending jig 31 configured to bend the rectangular conductor 2, five sway-prevention guides 50 arranged at regular intervals on the same circumference to prevent the edgewise coil 1 from losing its shape, the five sway-prevention guides 50 being configured so that when the rectangular conductor 2 is bent in the edgewise manner, the edgewise coil 1 is sandwiched between two adjacent ones of the five sway-prevention guides 50 in the clockwise direction, and a guide holding member 51 configured to be rotationally driven in synchronization with the bending of the rectangular conductor 2 in the edgewise manner and the feeding of the rectangular conductor 2.
