ABSTRACT:
A method for setting a straightening roller of a straightening unit designed to be translationally adjustable with an adjusting mechanism, and a setting device for performing the method. Each straightening roller to be adjusted is individually identified and then coupled, if necessary with simultaneous setting of an aligned mutual position, to the adjusting mechanism, whereby the respective position of the straightening roller is determined after the coupling and the position of the straightening roller, which is pre-selected and/or pre-calculated dependent on the process material, dimensions and straightening process, and is then set in relation to a previously determined limit position. The setting device has a roller positioner, a detachable coupling arranged between the roller positioner and the adjusting mechanism of an adjustable straightening roller of the straightening unit, whereby one coupling part is connected to the adjusting mechanism and another coupling part to the roller positioner, a sensor device is used to determine the actual position of the currently coupled straightening roller in relation to a limit position, and an initiablizable actuator is used for the automatic setting of a specific pre-selectable and/or calculable position of the coupled straightening roller in relation to the limit position.
