Abstract
A two part input shaft is drivingly connected to a crankshaft of a punch press for rotation at a predetermined speed. An adjustable cam drive mechanism drivingly connects the input shaft to a driven feed roll. Continuous rotation of the input shaft is converted by the adjustable cam drive mechanism to intermittent rotation of the feed roll. The intermittent rotation of the feed roll is timed with the press operation so that the feed roll intermittently advances a preselected length of the workpiece to the press after each press operation. A clamp arrangement releasably engages a first portion of the input shaft to a second portion of the input shaft so that, upon disengagement of the clamp arrangement, relative rotation is permitted between the input shaft first and second portions. The input shaft first portion is drivingly connected to the crankshaft of the press and the shaft second portion is drivingly connected to the adjustable cam drive mechanism. When the input shaft first and second portions are drivingly connected, the continuous rotation of the crankshaft is transmitted to the adjustable cam drive mechanism. Releasing the clamp disengages the shaft first and second portions from one another to permit adjustments to be made in the timed relationship between the feeding of the workpiece to the press and the operation of the press on the workpiece.
