Abstract

The invention concerns a method for regulation of the transverse profile of the coating quantity on a paper or any other web material in a coating station, in which the web is passed over a backup roll and a coating agent is smoothed by means of a coating blade loaded against the web. The quantity of coating agent applied onto the web is regulated by actuators acting upon the constructions of the coating station. In the method; the transverse profile of the coating quantity applied onto the web is measured constantly, and a differential profile of the measured transverse profile and the desired transverse profile is calculated. The differential profile is fed as a regulation quantity to the actuators that adjust the transverse profile of the coating quantity so as to correct the transverse profile. The invention is advantageously carried out so that, in the method, an equation is approximated by means of calculation which corresponds to the transverse differential profile of the web coating quantity between the measured transverse profile and the desired transverse profile, and out of said equation, the average error and/or inclination and/or curvature of the differential profile and/or the frequency of a cyclic error of coating quantity is/are determined, they parameters corresponding to said values being fed as regulation quantities to regulation devices that regulate the properties of coating quantity so as to correct the transverse profile. The invention further concerns a coating station construction intended for carrying out the method.
