Patent ID: 7794568

Claim:
A method for dewatering a fiber suspension in a twin-wire press, having an endless lower wire and an endless upper wire, and a first and a second dewatering table, which supports the respective wires such that an oblong dewatering space is defined by the wires between the wires, by which method the wires transport the fiber suspension under the compression of the wires by the dewatering tables in a predetermined direction, such that the fiber suspension is dewatered and forms a fiber web between the wires, the method comprising: applying a separate pressing force against one of said wires at an end of said dewatering tables located downstream in said predetermined direction including a subsequent roll arrangement of said twin wire press, so that said one of said wires presses the formed fiber web via the second wire against one of the dewatering tables and further dewaters the fiber web independently of the load on the fiber web achieved by the dewatering tables, and adjusting the separate pressing force so that a desired dryness of the fiber web leaving the dewatering tables is achieved.
