Abstract
A coating section for coating a traveling web of material, such as paper, wherein the web to be coated travels along a selected one of two different web paths. There is a lower counter roll and an upper press roll which define a nip between them and the distance apart of the two rolls is adjustable. A respective applicator for coating composition is on each of the first and second sides of the lower roll and on the third side of the upper roll, and the third side is the same side of the coating section as the first side of the lower roll. First web guide rollers guide the web from below, past the counter roll and the first applicator and not through the nip. Second guide rollers guide the web through the nip.
