摘要： A method and apparatus for coating a paper or board web, wherein the web to be coated is brought to a film transfer coater and taken to a nip between the film transfer roll of the coater and its backing roll, and coating mix is applied onto the surface of the film transfer roll. The web is taken through the nip between the rolls and the rolls are turned, whereby the coating mix applied onto the applicator roll is at least partly transferred onto the surface of the web. The web is supported through the nip by means of a belt traveling at the same speed as the web, the belt having been arranged to travel on the backing roll. The web is taken onto the surface of the belt prior to the nip and separated from the belt after the nip, and it is pressed against the film transfer roll by means of the belt. The length of the path where the web and the film transfer roll are in contact with each other is controlled by varying the position of the web and the belt.

摘要： A method and apparatus for producing paperboard, the method comprising the steps of applying a coating mix layer having a thickness greater than that of the final coat thickness to the surface of the web being coated using a coating mix formulation in which the solids content is at least 55%, passing the web with the coat applied thereto to a doctor blade located downstream in the travel direction of the web at a distance from the applicator apparatus such that the dwell time from the application step of the coating mix to the doctoring step is at least 130 ms, and smoothing the coat layer to its final thickness by means of a doctor blade. By this method a smooth surface can be obtained even on high coat weights.
