Zusammenfassung:	Methods for dewatering a fiber suspension in a twin-wire press, having a lower wire and an upper wire, and a first and a second dewatering table, which supports the wires such that a dewatering space is defined by the wires, are disclosed. The wires transport the fiber suspension under compression of the wires by the dewatering tables, such that the fiber suspension is dewatered and forms a fiber web between the wires. A separate pressing force is applied against one of the wires, such that this wire presses the formed fiber web via the second wire against one of the dewatering tables and further dewaters the fiber web. The separate pressing force is adjusted such that a desired dryness of the fiber web leaving the dewatering tables is achieved. A twin-wire press is also disclosed.
