Method of operating a roll stand for rolling a metal strip with at least one lateral guiding straight-edge, which is arranged in the entry and/or exit of the roll stand on at least one of the two sides as seen in transport direction of the metal strip, for guiding the metal strip, comprising the following steps: performing a pivot regulation in which an actual wedge shape of the metal strip is determined and regulated to a predetermined target wedge shape by dynamic adjustment of the work rolls in the roll stand; and performing a positional or force control of the at least one lateral guiding straight-edge; wherein the pivot regulation and the positional or force control of the lateral guiding straight-edge can be coupled with one another; characterised in that optionally an actual offset of the metal strip relative to the centre line of the roll stand after the rolling is determined; the actual wedge shapes and/or the actual offset is or are checked for allowability; and the coupling is carried out only when either the determined actual wedge shape is greater than a predetermined maximum permissible wedge shape and/or when the determined actual offset of the metal strip after the rolling is impermissible because it is greater than a predetermined maximum permissible wedge shape; and the coupling then comprises the following step: individual control of the lateral guiding straight-edge on at least one of the two sides - as seen in transport direction of the metal strip - in the entry and/or exit of the roll stand by a force or position target value, which is individually predetermined in accordance with the determined actual wedge shape and/or in accordance with the determined actual offset, for prevention of formation of camber in the metal strip exiting the roll stand. performing a pivot regulation in which an actual wedge shape of the metal strip is determined and regulated to a predetermined target wedge shape by dynamic adjustment of the work rolls in the roll stand; and performing a positional or force control of the at least one lateral guiding straight-edge; wherein the pivot regulation and the positional or force control of the lateral guiding straight-edge can be coupled with one another; characterised in that optionally an actual offset of the metal strip relative to the centre line of the roll stand after the rolling is determined; the actual wedge shapes and/or the actual offset is or are checked for allowability; and the coupling is carried out only when either the determined actual wedge shape is greater than a predetermined maximum permissible wedge shape and/or when the determined actual offset of the metal strip after the rolling is impermissible because it is greater than a predetermined maximum permissible wedge shape; and the coupling then comprises the following step: individual control of the lateral guiding straight-edge on at least one of the two sides - as seen in transport direction of the metal strip - in the entry and/or exit of the roll stand by a force or position target value, which is individually predetermined in accordance with the determined actual wedge shape and/or in accordance with the determined actual offset, for prevention of formation of camber in the metal strip exiting the roll stand.
