ABSTRACT:
Coil winding apparatus includes wire tap pulling needles with the needles for pulling taps on each side of the bobbin mounted on separate mounting plates with a quick change cam mechanism and springs for spacing the plates and thus the needles to accommodate coil bobbins of different sizes with terminals at different spacings. The apparatus also includes wire feed means for clamping the wire between the winding flyers and the wire supply rolls to advance the wire at a rate greater than required by the flyer to make a winding to provide slack in the wire just prior to retraction of the tap pull needles so that the wire does not break or stretch during the tap pulling sequence.
