Abstract
A stator coil producing method and a stator coil production machine. The stator coil is used in an electric rotating machine. The stator coil production machine includes a rotary retainer which retains and moves shaping press pairs along a looped path to press or shape portions of a conductor wire into in-slot portions to be disposed in slots of a stator core and coil-end portions which extend outside the slots. The method comprises a coil-end portion shaping step of bringing press members of each of the shaping press pairs close to each other in sequence to shape the coil-end portions and an in-slot portion shaping step of advancing the shaping press pairs on the looped path in contact with the cam mechanism and also moving selected ones of the shaping press pairs in sequence in a direction perpendicular to the path to shape the in-slot portions.
