Abstract

The invention relates to a method for surface sizing a fibrous web. The method comprises bringing a fibrous web to a surface sizing station, at which a surface size, which has its dry matter content preferably within the range of 20-30%, is applied to at least one side thereof as spray application. The application stage is followed by conducting the fibrous web, optionally by way of a surface sizing nip and/or optionally by way of a separate drying stage, to a metal belt-equipped processing unit, which includes a metal belt adapted to circle around at least one guide element, outside said metal belt being provided at least one backing element establishing a contact face with the metal belt, such that between the metal belt and the backing element is provided an extended web processing zone, the web to be processed being conducted therethrough.
