ABSTRACT:
Paper or cardboard webs are coated by dipping an applicator roll in the liquid coating material and forming a uniform coating on that roll with a grooved doctor bar before applying the coating to the web against a drum. Thereafter, any excess is removed from the web by a doctor blade which is pressed against the web while it is on the drum.
