Abstract
A pinch roll delivers a respective rolled product. A control device opens the pinch roll at a respective trigger time and at a respective transport speed of the respective rolled product. The control device determines the respective trigger time and/or the respective transport speed using a model that depends on a coefficient of friction. After opening the pinch roll, a measuring device detects iteratively a position or a derivation in time of the position of the respective rolled product. The detected positions or the detected derivations in time of the position are provided to the control device. The control device in dependency on the positions or the derivations in time of the position updates the coefficient of friction and uses the updated coefficient of friction for determining the respective trigger time and/or the respective transport speed for the next rolled product delivered by the pinch roll.
