Abstract

A press mechanism for dewatering a travelling fibrous web comprises: opposed first and second press rolls 10, 12 defining a nip N therebetween for receiving a travelling fibrous web W and applying pressure to the web for expressing water therefrom an endless looped belt B passing through the nip formed of a thin noncompressible material, such as metal, with small perforations in the belt for receiving liquid expressed from the web W in the nip and guide rolls 14-18 for guiding the belt through the press nip. The press roll 12 engaging the belt B is peripherally grooved, and a suction box 23 is provided for removing liquid from the perforations in the belt in advance of entry of the perforations into the nip N.
