ABSTRACT:
An apparatus for forming a field coil with a low load comprises a rotary table, a reel table to be turned together with the rotary table, six reel bars for guiding and winding a conductor into the coil according to the rotation of the rotary table, and six shaping units disposed alternately with the reel bars. The shaping units are radially movable on the rotary table. A groove-cam-type moving mechanism radially reciprocates, at a rate of one reciprocation per turn of the rotary table, the shaping units on the rotary table with predetermined phase shifts between the movements of the shaping units, thereby pushing the conductor stretched between the reel bars toward the center of the rotary table and shaping the conductor.
