METHOD OF PRODUCING PAPER OR CARDBOARD

摘要

Method of coating paper or cardboard webs. The method comprises the steps of applying a coating colour onto a smooth surface to form a first layer, drying the first layer at least partially, applying at least one second coating colour with different coating mineral particles on top of the first layer to form at least one second layer, which contains an amount of binding polymer, partially drying the second layer on the first layer to form a combined layer, and transferring the combined layer onto the paper or card-board web. By means of the invention it is possible to transfer the coating curtain onto the web without interference from any unevenness or air streams associated with the moving web.
