ABSTRACT:
The present invention comprises a method of helically winding wire on an endless ring-shaped core, and an apparatus used for practicing such method, which feature novel means for fixing the wire to the core when coiling the former on the latter. Heretofore, fixing of the wire to be wound to the core has been accomplished by either soldering the end of the wire to the core or by manually holding the wire end, but these methods are poor in working efficiency and reliability. According to the present invention, the wire is securely fixed to the core by projecting the leading end of the wire in a direction pointing away from the section of contact with the core and holding the same against rotation about the circumferential line of the core with a guide disposed about the core periphery and having transfer means thereon for permitting passage of the wire therethrough.
