Patent ID: 7137338

Claim:
A method for controlling a cutting register error in a rotary press including a plurality of clamping points through which a web is drawn, comprising the steps of: registering, by a first sensor, a cutting register by sensing one of a specific item of image information and measuring marks on the web running through the rotary press; supplying a first register signal from the first sensor to a control device, the first register signal being generated by the first sensor in response to the cutting register; registering, by a second sensor, a web tension of the printed web by sensing the web tension; supplying a second register signal from the second sensor to the control device, the second register signal being generated by the second sensor in response to the web tension; determining, by the control device, one of a partial cutting register error and a total cutting register error from the first register signal, the one of a partial and total cutting register error representing a deviation of the cutting register from its intended position at the time of registering; and influencing, by the control device, the one of the partial and total cutting register error and the web tension, wherein the influencing of the cutting register error is decoupled from the influencing of the web tension.
