To easily perform the cutting operation without high quality and technique, by comprising a rotation supporting part of which an axial direction is located in parallel with an axial direction of a knife cylinder, and which is kept into contact with an outer periphery of an anvil part while permitting the rotation of the anvil part, for supporting the anvil part.
A rotary cut-off device rotates and drives a long support cylinder 8 while keeping in phase with a travelling speed of a sheet, when the sheet is fed, and the control of the rotation from the acceleration to the deceleration, and from the deceleration to the acceleration at a rotation peripheral speed which is almost agreed with the travelling speed of the sheet, is executed by a controller 12, so that the cutting operation is started when a knife cylinder 1 is moved to a specific cutting length on the basis of the travelling length of the sheet measured by the detector. Then a knife 2 spirally mounted on the knife cylinder 1, is stopped to one edge of an anvil 7 through the sheet, the engagement is advanced in an axial direction, while successively separating the sheet, and the cutting is completed by the engagement with the other edge part of the sheet.
