Japanese Patent JP2003508190
Kind Code:
A
Abstract:
A curtain coater and a curtain-coating method for coating a moving web of paper or board are described. The curtain coater has an applicator nozzle for applying a coating mix to the surface of the web in the form of a continuous curtain extending uniformly over the cross-machine width of the web. In one aspect, a doctoring means located upstream (in terms of the direction of travel of the web) from the applicator nozzle substantially removes the air boundary layer traveling on the surface of the web. In another aspect, the doctoring means comprises a suction nozzle for removing the air boundary layer. In yet another aspect, a gas nozzle located downstream from the applicator nozzle sprays gas on the coating curtain in order to help apply the coating mix to the surface of the web.
