Abstract
A cutting and transport roller and a process for cutting the material webs which rest on the peripheral surface of the cutting and transport roller. In so doing, the material webs are severed with the aid of a cutter, which is located inside the shell of the cutting and transport roller in its resting position and which exhibits at least one knife, which during the cutting process of the material web reaches through an opening in the shell of the cutting and transport roller. The cutting motion, which is executed by the cutting surfaces of the knife during the cutting process, exhibits rotary components, whereby the rotational motions of the knife run about an axis of rotation, which is either parallel or at an acute angle to a perpendicular line on the plane which is defined by the radial (r) and axial (z) coordinates of the cutting and transport roller.
