Abstract
A coil segment forming apparatus includes a second bending section for bending a first bent body consisting of a pair of slot insertion portions that are substantially parallel to each other and a linking portion for connecting the pair of slot insertion portions formed in the same plane. The bending of the first bent body is carried out in a plane perpendicular to the aforementioned same plane. The second bending section has a plurality of pairs of press jigs arranged to oppose to each other in directions intersecting with the aforementioned same plane for pinching and pressing the linking portion, and a plurality of drive mechanisms for moving respectively the plurality of pairs of press jigs in directions intersecting with the aforementioned same plane based on moving amounts respectively set depending on forming conditions of the coil segment to be formed.
