ABSTRACT:
An input shaft is drivingly connected to a crankshaft of a punch press for rotation at a preselected speed. A geared cam drive drivingly connects the input shaft to a driven feed roll so that continuous rotation of the input shaft is converted to intermittent rotation of the feed roll. The intermittent rotation of the feed roll is timed with the punching operation so that the feed roll intermittently advances a preselected length of stock material to the punch press after each punching operation. Bevel gears drivingly connect the input shaft to a pull roll that rotates to continuously unreel stock material from a coil. During the punching operation, rotation of the feed roll is interrupted forming a loop in the stock material between the pull roll and the feed roll. At the end of each punching operation the material forming the loop is fed by the feed roll to the punch press so that the stock material between the pull roll and the feed roll moves from a loop to a horizontal position to insure feeding the same length of material to the punch press for each cycle of operation.
