A method for computer-aided sheet running control in a sheet-fed printing machine includes, during a printing operation, using a measuring sensor to detect a printed sheet in the printing machine and using an activation sensor to initiate measuring performed by the measuring sensor by emitting an activation signal. The activation sensor is mechanically fixedly installed without adjustment, and temporal deviations of the activation signal are determined and compensated. A system for computer-aided sheet running control in a sheet-fed printing machine is also provided.

Method and system for improved sheet running control in a sheet-fed printing machine

An apparatus for conveying sheets through a printing machine allows continuous monitoring of the position of a sheet with regard to a guide element over a long time period. There is provided a circulating conveyor element with grippers in which the sheet is held at a leading edge. A device for setting the position of the sheet can adjust the position with regard to a desired position. A measuring configuration measures the position and the presence of the sheet. A control device is connected to the device for setting the position and to the measuring configuration. The measuring configuration is mounted so as to circulate with the conveyor element.
