Patent ID: 6874724

Claim:
A method for the positionally correct winding up of a metal strip in a coiling device, the metal strip, in particular rolled hot strip, being fed to the coiling device by a driving device including driving rollers with a gap between said rollers, the driving rollers being tiltable in relation to one another by a mutli-variable controller by means of actuators for changing the gap between the driving rollers, wherein the controller is fed (a) the position of the edge of the metal strip upstream of the driving device as a measured variable and as a setpoint reference variable, (b) the setpoint strip tension between the driving rollers and the coiling device as a further reference variable, and (c) the surface geometry of the metal strip as a measured variable; wherein the actual strip tension between said driving rollers and the coiling device is determined by a model-aided determination of measurable variable and is fed to the multi-variable controller as a measured variable; and wherein the driving roller drive and the setting of the driving roller gap are activated by said controller.
