摘要

Device for determining the amount of coating agent in a to a fibrous web (w) applied coating agent layers (44) with respect to a single coating agent layers when the case of a multilayer coating, wherein the fibrous web (w) by means of coating with two or more coating agent layers (44) with the use of a sliding means for feeding - curtain coating is coated, which has a nozzle beam (40) with at least two supply chambers (12) and which are in connection with the same nozzle slots (30) for supplying at least two coating layers on the means by the nozzle bar (40) has elapsed, which is formed of sliding web (35), characterized in that for measuring the quantity of the coating agent current in each coating agent layer measuring devices (28) in the supply pipe (22) of the respective coating agent layer in front of the feeding of the coating agent in the supply chamber (12) of the coating agent layer are arranged, and that the amount of the coating composition in the respective coating agent layer on the fiber web is provided for this purpose, on the basis of the amount of the current to be determined, which is measured by simultaneous be taken into account of at least the speed (v) of the fiber web (w) and..
