ABSTRACT:
A rotary die cutting and scoring machine including a free wheeling resiliently covered anvil roll, an adjustable pusher having a velocity profile insuring that the velocity of the leading edge of the fed sheets matches the peripheral speed of the cutting roll, guides for guiding the side edges of the fed sheets maintaining their guide services parallel to the direction of feed and a reciprocating cutting tool for removing a selected portion of the resilient coating on said anvil roll to produce a fresh anvil surface. The machine also includes a support plate located on the reciprocating pusher to insure accurate feeding of warped sheets.
