Abstract
A control device moves a split claw (11) holding a projecting portion (4d) of an eighth-layer coil segment (4) in a counterclockwise direction D1. At this time, the control device moves first to third extended blades (13a) to (13c) in an outward direction D3 so that the projecting portion (4d) of the eighth-layer coil segment (4) is bent in the outward direction D3. Then, the control device moves the first to third extended blades (13a) to (13c) in an inward direction D4. Through the above steps, the projecting portion (4d) of the eighth-layer coil segment (4) is bent in the counterclockwise direction D1 while being bent in the outward direction D3. As a result, a return force tending to return in the inward direction D4 is generated by an elastic deformation force.
