Abstract

The invention relates to a method and apparatus for removing water in paper-making, wherein paper is formed by feeding pulp to a wire section (2) through a headbox, a web is formed at the wire section, and the web is led from the wire section to a drying section (4) through a press section (3). According to the invention, dewatering the web is enhanced and moisture content of the paper is reduced by removing water from the web (5) the is being formed by at least one dewatering unit (8) comprising a belt circulating member (10) with a belt (11) and at least two rolls (12) over which the belt is arranged to pass.
