ABSTRACT:
A piece of scrap material cut from a web passing through the nip of a pair of rotary cutting dies is removed by a mechanism with an actuator carried by one of the cylinders, a pin and ejector sleeve carried by the other cylinder and a release roller downstream of the nip and adjacent the other cylinder. As the scrap piece is cut from the web it is impaled on the pin by cooperation with the actuator which also retracts the sleeve to expose the pin and actuates an indexable ring to releasably retain the sleeve in a retracted position from the head of pin. The scrap piece is impaled on the pin and is carried away from the nip and web by rotation of the other cylinder and downstream thereof passes through the nip of a roller and the other cylinder which moves the sleeve and actuates the ring to release the sleeve so that as it passes out of the nip it moves to the fully extended position to strip the cut piece from the pin and thereby release and remove it from the cylinder. Preferably, the released scrap piece is propelled into a chute or other container for collecting scrap pieces.
