PURPOSE:To perfectly and beautifully peel a polyurethane insulating layer in the corresponding position to a lead wire. CONSTITUTION:A polyurethane insulating layer 4 for enamel wire is baked and hardened on a coil winding 1. The end part of a polyurethane insulating layer 4A in the corresponding position 6 to a lead wire 5 in the polyurethane insulating layer 4 is damaged 8. The polyurethane insulating layer 4A in this corresponding position is peeled by drawing. Thus, the coil winding 1 can be surely insulated. The polyurethane insulating layer 4A to which the lead wire 5 corresponds can be perfectly peeled. |
