Abstract
A winding apparatus includes a nozzle that is adapted to rotate about a core along a locus that is inclined relative to a center line of the core, wire material winding members that are adapted to guide a wire material wound via the nozzle to the core, and a core rotating mechanism that is adapted to rotate the core relative to the wire material winding members. The wire material winding members are disposed on either side of the core so as to sandwich a plane that includes both a rotary center of the nozzle and the center line of the core, whereby the wire material winding members extend in a tangential direction to the core such that respective tip ends thereof are oriented in a rotation direction of the core. The wire material is successively wound diagonally around the core.
