Abrégé

A device for coating a metal strip with a liquid coating material comprises a coating container filled with, for example, liquid zinc. After the metal strip exits the coating container, liquid coating material adheres to the metal strip. Excess coating material is blown away from the surface of the metal strip by a blowing device. Thereafter, the metal strip runs through an electromagnetic stabilization device which is supported on the blowing device. Disturbing influences may cause the metal strip to no longer run centrally through a slot of the blowing device. A displacement or re-alignment of the blowing device is then required to guide the metal strip back to the set middle position. A first displacing device displaces the electromagnetic stabilization device relative to the blowing device in the plane transverse to the direction of transport of the metal strip to avoid an undesirable displacement of the electromagnetic stabilization device.

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.
