Firstly, a flat conductor raw wire is formed in a rectangular cross-section and bent in a continuous meandering pattern in a same plane to include in-slot wire portions arranged in each slot of the stator core, coil-end wire portions arranged as a coil end outside the slots, and bent portions joining the in-slot wire portions and the coil-end wire portions. Thereafter, in a setting step, the bent portions located at the opposite ends of the in-slot wire portion are grasped by a pair of grasping tools and the in-slot wire portion is grasped by a twisting jig. Next, in a processing step, the bent portions are twisted and bent into crank-shape by displacing a predetermined axis to a predetermined direction while rotating the twisting jig about the axis. The flat conductor is obtained by performing the setting step and the processing step each of the in-slot wire portions. |
