Abstract

PURPOSE: To improve an yield of a material, and to insert windings easily into the slots of wound cores by punching two rectilinear core blank sections having the same shape from one band plate and molding these sections to the wound cores.
CONSTITUTION: Holes 7 are punched zigzag at sections as the nose sections of the teeth of one band plate 8. Teeth 2, face width of which is kept constant and nose sections of which are formed to an arcuate shape, and slots 3 having the same contour shapes as the teeth 2 are punched continuously, thus acquiring two rectilinear core blank shapes 9 mutually having the same shape. The rectilinear core blank sections 9 are molded successively to the arcuate shape while the tooth-slot forming side 9a is directed inward, thus shaping a wound core 1. Strands are wound into each slot 3 of the wound core 1, and windings 4 previously molded to an elliptical form are inserted. The nose sections 5 of teeth and the holes 7 are crushed in the radial direction, and the holes 7 are removed while the nose sections 5 of teeth are deformed in the circumferential direction. The nose sections 5 of teeth is widened, and the clearances of the slot opening sections 6 are narrowed.
