<p>PURPOSE:To enable simultaneously fabrication of a number of coils by a relatively simple construction with a plurality of winding core pieces, driving means and coil retaining member. CONSTITUTION:Wire material 1a is wound at one end on the respective grooves 4 in the expanded radius state of respective winding core pieces 3, then the pieces 3 are rotated through a holder 6 via a motor 8, and the material 1a is wound in the respective grooves 4. When the material 1a is wound in predetermined length, the motor 8 is stopped operating to move the respective coil retaining members 10 toward axial center 5 to bring the members 10 into contact with the coil. Then, the pieces 3 are moved to approach each other to reduce the respective diameters. Thereafter, the members 10 are moved to remove the coils from the respective pieces 3.</p> |
