Abstract
A conductor wire insulating film separating method disclosed includes: a preparing step involving preparing rectangular cross-section coil pieces each of which is a conductor wire coated with insulating film and used to provide a stator coil of rotary electric machine; a delivering-in step involving, after the preparing step, delivering coil pieces into a laser separator, with coil pieces aligned such that extremities thereof are adjacent to each other; an applying step involving, after the delivering-in step, continuously applying film removing laser to the extremities of the aligned coil pieces such that the laser is applied to one extremity and then to another extremity, thus removing at least portions of the insulating film from the extremities of the coil pieces; and a delivering-out step involving delivering the coil pieces, from which the at least portions of the insulating film have been removed by the applying step, out of the laser separator.
