ABSTRACT:
A roller hold down is designed to restrain parts being cut from a stack of flat sheets. The roller hold down eliminates the need for secondary fastening means to restrain the parts during the cutting operation. The parts are restrained in position on a flat worktable by a pair of cylindrical rollers adjacent the cutter which force the parts against the table. By use of the roller hold down, the restraining force applied through the rollers follows the excursions of the cutter and is applied near the cutter where the force is the most effective.
