ABSTRACT:
A coil-forming apparatus includes three pinch wheels spaced about the periphery of an idler roller rotatably mounted to a platen. Wire is fed through the platen between the pinch wheels and idler roller where the wire is held in place. Rotation of the platen relative to the idler roller imparts a longitudinal twist to the wire, and the pinch wheels drivingly engage the twisted wire with a controlled gripping force and form it into coils against a tapered, forward surface of the idler roller. The coiled wire is then advanced outwardly from the idler roller to a mandrel having an axially adjustable pitch setting roller which engages the coil at a predetermined location from the idler roller to set the wire with the desired pitch.
