ABSTRACT:
An improved rotary die cutter apparatus where an anvil roller is powered separately from the die roller. The anvil roller and one embodiment of the present invention is completely unpowered or freewheeling as soon as cardboard is fed through the rotary die cutting apparatus, and in another embodiment is driven at a compensating speed either slightly slower at the same speed as or faster than the die cutting roller to eliminate noise pollution and tolerance problems.
