Abstract
This application discloses removing scrap trimmed from a moving web with a series of pins mounted upon a disc which brings the pins into an impaling engagement in the scrap. The movement of the pins into such engagement is carefully synchronized between the cutting roller and the pins. The scrap is removed from the pins by causing it to be grasped between an abutment on one side and a nip roller on the other side and pulled from the pins at the same time as the pins are being withdrawn.
