Abstract
There is provided a system for readily and efficiently fabricating a wound coil composed of a bobbinless coil. The system includes a coil winding device having an upper jig to which an upper plate is attached and a lower jig to which a lower plate is attached which are provided so as to be relatively displaceable and a tension device for applying predetermined tension to a wire rod fed from a wire rod supplying source. The coil winding device is provided with a claw section having first through third split claws that function as a winding section around which the wire rod is wound between the upper and lower plates and that slide in a radial direction when the upper jig is assembled coaxially with the lower jig.
