Abstract (en)
[origin: WO9512031A1] A fountain applicator for applying coating liquid onto a web of paper carried past the applicator, has a coating liquid flow path that includes a curved surface along which a sheet of the coating liquid is flowed to subject the sheet to centrifugal force to cause air entrained in the coating liquid to move toward one side of the sheet away from the curved surface. After being flowed along the curved surface, the sheet of coating liquid is directed toward the web in a free standing jet curtain of coating liquid, to contact an opposite relatively air-free side of the coating liquid sheet against the web surface while the one side of the sheet is out of substantial contact with the web surface. Contacting the web with coating liquid that is relatively free of entrained air minimizes the occurrence of skip coating on the web, especially when the web is travelling past the applicator at high speeds.
