Abstract
A coil winding apparatus 1 includes a transvers mechanism which displaces a wire supply part 8 and a spinds 5 to which a bobbin 4 is fitted relative to each other in an axial direction. This traverse mechanism includes a first traverse mechanism 11 and a second traverse mechanism 15 which have a different displacement range and displacement pitch. The first traverse mechanism 11 and second traversemechanism 15 are displaced independently of one another, so even when a wire of fine diameter is rapidly wound on a narrow width, the coil winding alignment does not break down, and the coil turns can be wound at high speed in an orderly arrangement.
