Coil forming apparatus and coil forming method

A coil forming apparatus that forms a belt-shaped coil in a wound state, the belt-shaped coil including a plurality of straight portions and side ends provided on both ends of the plurality of straight portions, the apparatus comprising:

• a coil winding jig that winds the belt-shaped coil, the coil winding jig including a jig body arranged between axial ends of the coil winding jig and including a plurality of comb-shaped grooves on the outer periphery thereof each of which can hold a respective one of the plurality of straight portions therein;
• a coil conveying organizer that pivotally conveys the belt-shaped coil along at least a portion of the outer periphery of the coil winding jig;
• and
• guide members with a substantially U-shape that are provided laterally along the coil conveying organizer in a vicinity of both axial ends of the coil winding jig and guide the belt-shaped coil in an arc shape along the outer periphery of the coil winding jig while being in contact with the side ends of the belt-shaped coil to insert the plurality of straight portions into a respective one of the plurality of comb-shaped grooves of the coil winding jig in a second half portion of the coil conveying organizer upon pivot conveyance,
• wherein the guide members include a reforming portion in a first half portion of the coil conveying organizer upon pivot conveyance, and the reforming portion including a guide plate that deforms and reforms the belt-shaped coil in an arc shape along the outer periphery of the coil winding jig in a state sandwiching the side ends of the belt-shaped coil between the reforming plate and a reforming groove of the guide members.
