Abstract
A forming machine for forming a loop winding having a plurality of meandering parts and disposed in a stator of a motor which includes: a first die unit having a plurality of first dies spaced from each other at regular intervals in a circumferential direction; and a second die unit having a plurality of second dies which are spaced from each other at the same intervals as the regular intervals in a circumferential direction and which are each disposed between adjacent ones of the first dies, wherein each of the second dies has a winding holding part for holding a loop winding; and the first die unit and the second die unit are each provided with a winding diameter reducing means for reducing the loop winding in the radial direction thereof according to a displacement of the first die unit in the axial direction relative to the loop winding held by the winding holding parts.
