Method and device for coating a metal strip with a coating material which is at first still liquid

A method of coating a metal strip with an initially still liquid coating material, comprising:

• passing the metal strip to be coated through a coating container filled with the liquid coating material;
• blowing excess parts of the still liquid coating material off the surface of the metal strip with the help of a blowing device after passage through the coating container;
• stabilising the metal strip, after leaving the blowing device, with the help of an electromagnetic stabilising device which is arranged downstream of the blowing device in the transport direction of the metal strip and which is supported on the blowing device;
• regulating the actual position of the metal strip to the predetermined target centre position by suitable displacement of the blowing device in a plane transverse to the transport direction of the metal strip;
• displacing the electromagnetic stabilising device relative to the blowing device in a plane transverse to the transport direction of the metal strip so that the actual position of the metal strip at least approximately corresponds with a predetermined target centre position in the slot of the electromagnetic stabilising device;
• and
• wherein deviation of the actual position of the metal strip from a predetermined target centre position in the slot of the blowing device is detected;
• the displacement of the blowing device is directly or indirectly detected relative to a pass line reference position;
• and
• the displacement of the electromagnetic stabilising device is carried out as a function of and in opposite direction to the detected displacement of the blowing device so that as a result the electromagnetic stabilising device remains at its original location.
