Abstract
The present invention is to provide a process for the preparation of coil for an electric appliance by which a coil for electric appliances comprising an edgewise wound square coil having small intervals between coils and high quality can be easily prepared in good productivity and low-cost. The coil for electric appliance comprising edgewise wound square coilis prepared by processing mechanically an electrically conductive flat plate to form plural strip-shaped coil fragmentsA toE, butting ends of the coil fragmentsA toE each other and welding the ends by beam to form plural one-turn square coils, each of the one-turn square coils having a ring-shape provided with a beginning endA and a terminal endB divided by a notchwhose location is different from one another in the one-turn square coils, and superposing the one-turn square coils on one another with shifting the locations of the notcheslittle by little in order so that the terminal and beginning ends of the one-turn square coils adjacent to each other are contact with each other to weld the terminal and beginning ends in the notch, whereby the one-turn square coils are spirally combined.
