Abstract

A method and an apparatus for removing liquid from a liquid containing material. The material is caused to run through a press nip formed by two rolls at least one of which is grooved together with an endless wire or felt. The liquid is removed from the press nip by creating a greater air pressure at the offrunning side of the press nip than at the oncoming side of it e.g. by blowing air between the wire or felt and the respective roll at the offrunning side, whereby water removed during the pressing effect is forced to flow in the direction upstream of the oncoming side of the press to reduce the re-wetting of the produced sheet of the material
