ABSTRACT:
In a device for alternatively one- or double-sided coating of a running paper web the final evening-out of the coating is made in a smoothing nip including a first roll and a counter member. The device includes means for leading the web from below upwards into the smoothing nip. At a considerable distance before the smoothing nip, there is a coating substance applicator including an applicator chamber, where the coating substance is brought into a substantially non-pressurized contact with the running web for adhering thereto and travelling therewith upwards to the smoothing nip. The web moves linearly from the applicator to the smoothing nip.
