ABSTRACT:
The coating device features a first applicator which, to begin with, forces coating substance applied on the shell of a web roll (1), in a press gap formed between said roll and a press roll (2), into the web (W), thereby impregnating it. This makes it possible to apply with maximum uniformity and without web breaks and wrinkles, immediately successively, a second coating layer during the still wet condition of the first layer where, naturally, again a web guide roll (3) is provided.
