Described is a method for operating a winding machine used for winding up and/or unwinding a winding material, said winding machine comprising a device for controlling and/or regulating the winding process. A variable value is monitored that concerns a machine state and/or a change in the winding material, and at least one parameter of said controlling and/or regulating device is modified in accordance with the change identified.

Method for operating a winding machine

There is described a regulating system for register adjustment in a printing press which has at least one printing unit, wherein the regulating system has at least one register regulator. In the regulating system, a pilot control variable and/or a register error estimated variable are/is provided for influencing the register adjustment. A drive bus is advantageously used for transferring these variables between different printing units, wherein the register regulation is advantageously distributed in a decentralized manner among different regulating devices for carrying out the drive regulation.

Register regulation in a printing press

In a method and a device for the detection, at the correct time, of pressure marks situated at regular intervals on a print web, use is made of cameras, with a processing unit which is assigned to the camera. The activation of the camera is no longer triggered externally in order to detect the pressure marks. Instead, the drive control system, which actuates a movement of the print web, is connected to a bus to which the cameras and therefore the processing units are also connected. It is thereby possible for the drive control system to provide the processing units with process data which the processing units can use to calculate detection times. The activation of the camera takes place, on the basis of the calculation, automatically by means of the cameras with the processing unit itself.
