ABSTRACT:
A magnet wire having generally round cross section is taken out from a wire pack and formed by a forming roller mechanism into a polygonal shape in cross section to be wound on a bobbin tightly, thereby increasing the space factor of a coil. Then, magnet wire having round cross section is wound in a portion where pressure may be applied from the outside. Since the round wire is easy to move and able to dodge the pressure, a reliable coil of a high space factor can be obtained.
