Abstract

This invention concerns a method for evening out the coating mixture and for separation of surplus coating mixture on a paper or cardboard web. Ordinary scraper blades and bars or an air doctor 4 are used to scrape off the coating mixture. When an air doctor process is used, the coating mixture applied to the web 1 is evened out on the surface of the web 1 by blowing air at high speed from the narrow slot 16 in the air doctor 4 against the web 1. Since the impulse force of the air is low, according to the invention a solid substance is mixed into the air jet in order to improve the scraping effect. <IMAGE>
