ABSTRACT:
A method for setting the cut register in a web-fed rotary press includes assigning a cut register function to a predetermined speed function, wherein the predetermined speed function describes a time curve of an operating speed of the rotary press starting from a predetermined initial value and the cut register function describes a time curve of the set value of the cut register, and changing the set value of the cut register continuously and synchronously in accordance with the associated cut register function during a variation in the operating speed of the rotary press according to the predetermined speed function, the cut register function being chosen empirically such that it counteracts a change in the actual value of the cut position as a result of the change in the operating speed.
