Abstract
Within a coating device, a metal strip first runs through a coating container with a liquid coating agent and then a stripping nozzle device for stripping off excess coating agent from the surface of the strip. After the stripping nozzle device, the strip runs through a strip stabilizing device with a plurality of magnets on both broad sides of the strip. A form control deviation is determined as the difference between an actual form of the strip and a desired form of the strip and this form control deviation is used for activating the magnets in order to transform the actual form of the strip into the desired form. The magnets of the strip stabilizing device may be moved in the widthwise direction of the strip into a traversing position in relation to the magnets on the respectively opposite broad side of the strip.
