Abstract
A method of coating at least one liquid medium onto a moving material web, in particular of paper or cardboard, in which method the material web is led either in a first mode of operation along a first treatment path or, in a second mode of operation, along a second treatment path, the material web being led along the first treatment path through a roll gap formed by a primary roll and a secondary roll for indirect coating of the liquid medium via the shell surface of the primary roll, or along the second treatment path over a region of the shell surface of the primary roll remote from the roll gap for directly coating the liquid medium onto the material web in the mentioned region of the shell surface of the primary roll, wherein the primary roll is driven in the one rotational direction in the first mode of operation and in the other rotational direction in the second mode of operation, and the respective general run-in and run-out direction for the material webs is substantially the same in the region of the primary and the secondary rolls along both treatment paths.
