Method of coating-peeling and coating-peeling apparatus of rectangular conductor wire

A method of coating-peeling of a rectangular conductor wire by which, assuming opposing side surfaces of the rectangular conductor wire to be a pair of peeling target side surfaces, peeling target portions of an insulating coating covering the peeling target side surfaces are respectively peeled by a pair of peeling blades that oppose each other at a distance, comprising:

• a gripping step in which abutting sections of a pair of gripping members abut on gripping target portions of the insulating coating covering the peeling target side surfaces, whereby the rectangular conductor wire is gripped between the abutting sections opposing each other sandwiching the gripping target portions;
• and
• a peeling step in which, in a state where the rectangular conductor wire has been gripped by the gripping members, a pair of the peeling blades are moved relatively so as to be orthogonal to an extending direction of the rectangular conductor wire and follow 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 from the peeling target side surfaces.
