ABSTRACT:
The invention concerns a coating system for running webs of cardboard or paper which are carried, or backed, by at least two moving surfaces, in which system the coating substance is applied first on at least one moving surface carrying the web and thereafter transferred, in a press gap formed by the moving surfaces, on the web on one or both sides. The invention is characterized by the following features: the moving surfaces are formed by two continuous belts; the belts proceed jointly with the web contained in between successively through a first press gap and through a second press gap, with each press gap being formed by two rolls that are movable relative to each other; the rotatable roll body of each of the rolls of the second press gap is backed against flexure by means of a stationary element; the diameter of the rolls of the second press gap amounts to maximally one-half, preferably less than one-third, of the diameter of the rolls of the first press gap.
