ABSTRACT:
A wire feeding and cutoff machine in which the feed mechanism continuously advances wire along a path past a wire cutoff arm and into an elongated wire guide having a stationary guide member and a movable closure member. The cutoff arm is pivotally mounted on a cutoff arm axis and is driven by a crank connected to the output shaft of a one-revolution clutch. The crank drives the cutoff arm and moves a cutter downwardly from an initial position and then back to clear the wire path during a first half of the crank revolution. A drive mechanism for the movable closure member is connected to the cutoff and moves movable closure to an open position in response to movement of the cutoff arm in a cutting stroke and to a closed position during movement of the cutoff arm in the return. The drive mechanism also operates an ejector pin for ejecting a wire from the wire guide when the movable closure member is opened.
