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.

Method and apparatus of a twin-wire press

A frame for a twin-wire press is disclosed including pairs of side members including upper and lower side members arranged on opposite sides of the press, between which upper and lower rolls are attached, a plurality of transverse beams arranged between the pairs of side members which themselves are sections of flat sheet metal and spacers for mutually releasably connecting the side members with the sheet metal being formed so that it permits a degree of curing in the vertical plane to facilitate access to the space between the upper and lower rolls. A method for exchanging wire in a twin-wire press of this type is also disclosed.

Pulp-dewatering roll press

Apparatus for sealing a roll press including a seal extending along at least one of a pair of press rolls, the seal including a resilient member extending from the vat in which the press rolls are disposed towards one of the press rolls and a wear member attached to the resilient member for contacting the outer shell surface of the vat press roll whereby the wear member can be replaced upon wearing down of same.
