A rotary die cutter includes a rotatable anvil cylinder; and a knife cylinder made rotatable in a face-to-face relation to and in synchronism with the anvil cylinder and having knives fixed on the cutter circumference thereof for subjecting a sheet running at the central portions of the two cylinders to a predetermined cutting treatment by clamping the same together with the anvil cylinder. A thin film having a tape adhered thereto is attached removably to the outer circumference of the anvil cylinder in registration with the corresponding edges of the knife cylinder.
