• FIG. 11 (D) shows four (8 8 a to 8 8 d) connecting coils 8 9.
• the wire 1 between the coil 8 8 d and the nozzle 4 is cut by the cutter 8 4.
• the first lead portion 26a of the first coiled coil 8a is drawn diagonally from the coil 8a as shown in Fig. 11 (D).
• the connecting coil 8 9 is held by the coil holding shaft 95. Therefore, the discharge rod 9 shown in the first embodiment is used. It can be easily recovered by using only 3.
• the inner surface of the divided chuck 24 e is provided with each coil 8 8 a so that the distance between the coils sequentially fed to the coil holding shaft 95 is constant.
• a plurality of guides 99 for locking ⁇ 8 8 d are provided at predetermined intervals.
• each time the winding of each coil of the connecting coil 8 9 is completed each coil goes to the coil holding shaft 9 5 coupled to the tip of the winding body 2 e. Led.
• the coil holding shaft 95 is formed with a smaller diameter than the winding shaft body 2 e, even if the flange 1 is thick, the coil that is wound on the winding shaft body 2 e can be held smoothly. Can lead to axis 95.
• the lead portions between the coils of the connecting coil are drawn out along the winding direction of the coils. Therefore, to form the lead portion, the wire wound around the coil is peeled off. It was necessary to bend the coil perpendicular to the outer peripheral surface of the coil.
• the rigidity of the wire 1 is large, so it takes a lot of labor to form the lead portion on the connecting wire between the coils of the dissimilar coil.
• the lead portion 26a can be formed only by closing the chuck 24 and the lead portion 26a can be formed by the forming pin 97. 2 6 b can be molded. Therefore, even when the wire 1 is thick, the lead end portion 26 a and the lead portion 26 b can be easily formed.
• the present invention can be applied to a connecting coil winding apparatus.
