The present invention relates to a method of coating-peeling and a coating-peeling apparatus. The method of coating-peeling includes a gripping step and a peeling step, and peels by a pair of peeling blades peeling target portions of an insulating coating covering peeling target side surfaces of a rectangular conductor wire. In the gripping step, abutting sections of a pair of gripping members abut on gripping target portions of the insulating coating, whereby the rectangular conductor wire is gripped between the abutting sections. In the peeling step, in a state where the rectangular conductor wire has been gripped by the gripping members, the peeling blades are moved relatively following a surface direction of the peeling target side surfaces while opposing each other sandwiching the peeling target side surfaces, whereby the peeling target portions are peeled.

Coating-peeling apparatus of rectangular conductor wire

An insulator of a coil winding component constituting part of a rotary electric machine is resin molded integrally with a divided iron core. A first accommodating groove in which a coil terminal wire can be arranged is formed on an outer end surface of a wiring member of the insulator. A plurality of recesses are formed in a circumferential direction of a stator core on a groove bottom surface of the first accommodating groove. Further, a rib, which supports the coil terminal wire that is arranged in the first accommodating groove, is disposed between the mutually adjacent recesses.
