COIL FORMING APPARATUS AND COIL FORMING METHOD

A coil molding apparatus being capable of easily forming the band-shaped coil into a wound state, without the winding posture in the coil winding jig being disturbed by spring back of the band-shaped coil. The coil molding apparatus includes: a coil winding jig for winding the band-shaped coil with inserting straight portions thereof into a plurality of comb-shaped grooves in the outer periphery; a coil conveying mechanism unit for pivotally conveying the band-shaped coil along the outer periphery of the coil winding jig; and guide members for inserting the band-shaped coil into the plurality of comb-shaped grooves by guiding in an arc shape while contacting with the side end of the band shaped groove thereby gradually reducing in diameter accompanying pivoting at a second half portion of pivot conveying of the band-shaped coil, then extending with maintaining curvature of the oprtion of which the diameter has already been reduced.
