Patent ID: 7496426

Claim:
A method for controlling a cut register in a web-fed rotary press, wherein a plurality of printing material webs are combined into one strand which is cross cut and folded in the web-fed rotary press, said method comprising the steps of: measuring a position of a cut register mark on a printed material web and thereby registering an actual value measurement of the position of the cut register mark on the printed material web; using the registered position in a control loop as an actual value of the positions of the cut register mark for cut register control; and correcting, in the control loop, a first set value of a cut register setting element assigned to the printing material web based on a mathematical model to approximately compensate for an error contribution of a proportion of the path of the printing material web that is not registered by the actual value measurement, the first set value being the value necessary to achieve a control difference of zero, the control difference being the difference between the measured actual value of the position of the cut and a desired value of the position of the cut.
