ABSTRACT:
A winding apparatus for winding a coated wire on the drum for making a coil which is used for a stator or an alternator. A sectional shape of the wire which is introduced to the winding apparatus is circular, and the wire is deformed in order to make the sectional shape of the wire polygonal, so that the polygonal wire is fed to the bobbin in order to be wound on the bobbin. The resulting coil wound by the apparatus has an increased density.
