Abstract
A method for cutting a running web includes the steps guiding the web over a circumferential surface of an abutment drum; rotating a blade, that extends in the axial direction of the abutment drum, about an axis of rotation parallel to the axis of the abutment drum; holding the blade in a retracted position in which a cutting edge of the blade is spaced apart from the web on the abutment drum; impacting the blade against the web and the surface of the abutment drum at a time when the blade passes through a plane that contains the axis of the abutment drum and the axis of rotation, supporting a knife shaft carrying the blade in an oscillating crank which in turn is mounted on a rotary eccentric, and controlling the impact movement of the blade by controlling the drive of the eccentric.
