Abstract

A rotary die cutter for cutting sheet material has a drive mechanism which reduces the shock applied between the work piece and the die. Including a drive train for the die cutting rollers which permits slippage. The drive train can have a tension belt system which allows slippage when excessive force is required at the die so that the shock on the prime mover and drive train is minimized.
