A coil winding jig (5), a coil winding machine employing the coil winding jig, and a coil winding method to be carried out by the coil winding machine are provided. The coil winding jig (5) comprises: a first block (50) having a first flange (50a) to which the free end of the wire is fixed; a second block (51) having a second flange (51a) and disposed opposite to and coaxially with the first block (50) with the front surface of the second flange (51a) facing the front surface of the first flange (50a) and spaced apart a distance corresponding to the width (w) of the coil (C) to be formed from the front surface of the first flange (50a); a third block (52) disposed coaxially with the second block (51), having a middle portion contained within the second block (51), and a coil form (52a) having a front end to be pressed against the first flange (50a) and projecting from the middle portion through a hole (51c) formed in the second flange (51a) toward the first flange (50a) of the first block (50). The coil form (52a) is tapered toward the first flange (50a), has an outer circumference consisting of inclined side surfaces (T) and is provided with steps (55) having a size smaller than the diameter of the wire on its side surfaces contiguously with the front surface of the second flange (51a). <IMAGE> |
