PURPOSE:To eliminate a mold for forming a winding and outer layer insulator, by winding and fixing a thin plate around the periphery of a winding drum, by forming in turn an inner insulating layer, conductor winding layer and outer insulating layer, by heating and hardening resin impregnated preliminarily in the inner and outer insulating layers, and by removing the winding drum and the thin plate. CONSTITUTION:Since the sleeve 12 of a winding drum is displaced relatively to the center axis 9 by rotating a handle 11, links 14, 15, 16 are displaced radially just as an umbrella is opened and closed. A thin plate 18 which is later removed is wound and fixed around the outer periphery of the winding drum pieces. A conductor wound layer 21a of conductor 21 and an outer insulating layer 22 are formed in turn through an inner insulating layer 19 and inter-layer insulating layers 20 on the bobbin which is constituted through the thin plate 18 by the winding drum 8, thus constituting a winding 17. Thereafter, resin which is preliminarily being impregnated in the inner and outer insulating layers 19, 22 is heated and hardened, and then the winding drum 8 and thin plate 18 are removed. |
