ABSTRACT:
The present invention relates to a device for coating traveling webs of paper or board having two web guide rolls closely adjacent each other. Each roll has an applicator associated on its periphery. The applicators cooperate with each other at least in part for the coating of the web directly one after the other, preferably within at most 0.15 seconds. The rolls are arranged one above the other--possibly somewhat laterally shifted from each other. The lower roll has an applicator chamber of a nozzle applicator in the region of its periphery remote from the upper roll. The upper roll has at least one of the following on its web-entrance side--with respect to the lower roll--a sump chamber for coating composition formed of a doctor element and its mount and on its other side, an applicator chamber of a nozzle applicator. The lower roll may be adapted to be swung or lowered away from the upper roll and/or the upper roll may be liftable away from the lower roll.
