Abstract

PURPOSE:To prevent the shortcircuit and improper insulation of a welded part without burr by winding two layers of sheet-shaped conductor boundle isolated from insulating coating at the prescribed interval in advance, cutting at the isolated part, removing the exposed core wires, and then welding them. CONSTITUTION:The insulating film of a sheet-shaped conductor boudle 1 is isolated at the prescribed gradient at the every prescribed interval L to form insulating film isolated part 2 exposed with the core wires. The bundle 1 is spirally wound on the periphery of the cylindrical wound core 4 that both ends 3 of the part 2 are coincided to form an inner coil 5. Further, the same bundle 1 is reversely spirally wound to coincide with the position of the isolated part 2 to form an outer layer coil 6. The inner and outer layer coils are cut at the part 2, the exposed core wires 11 are removed until becoming in the same plane as the film 10, they are then welded to form a closed loop.
