Abstract: A method and apparatus for coating a moving web of paper of paper-board. In the method, the web to be coated is passed to a coater station, wherein a coat layer is applied to at least one surface of the web, and the web is dried at least to some degree and passed to the next treatment step. The coat is applied by spraying the coating mix on the web surface by a high-pressure spraying nozzles, the pattern width covered by a single nozzle is essentially narrower than the cross-machine width of the web being coated.

Abstract: A method and apparatus for coating a moving web of paper or paperboard. The web to be coated is passed to a coater station, wherein a coat layer is applied to at least one surface of the web by means of high-pressure spraying nozzles, whereby the pattern width covered by a single nozzle is essentially narrower than the cross-machine width of the web being coated. The nozzles are located in an enclosure and the excess coat mist formed in the process is removed by means of suction tubes, and advantageously, with the help of a falling film of coating mix flowing down the internal wall(s) of the enclosure.
