摘要： A paper or board machine and a method for passing a paper or board web from a forming section to a press section in a paper or board machine wherein the web is carried on a first wire in the forming section or transferred to a first wire from a forming wire of the forming section. The web that runs on the first wire is made to adhere in a transfer and pre-press zone to an outside face of a transfer belt which is substantially non-water-receiving. The pre-press zone includes an extended nip defined by an extended-nip roll and a smooth-faced press roll, the extended-nip roll having a hose mantle and a press shoe arranged in a loop of the hose mantle. After this pre-press zone, the web is separated substantially immediately from the wire and passed on support of the transfer belt onto the next press fabric in the press section and/or into the next press nip. In the pre-press zone or zones, a substantial amount of water is removed out of the web substantially in one direction only, and, at the same time, the web is made to adhere reliably to the outside face of the transfer belt.

摘要： A method and device for removing water from a paper or board web and for passing the web as a closed draw from a forming wire or transfer wire of the web former to the press section and through one or more dewatering press nips in the press section. The web that runs on the forming wire or transfer wire is made to adhere in a transfer and pre-press zone to an outside face of a transfer belt which is substantially non-water-receiving. After this pre-press zone, the web is separated substantially immediately from the wire and passed on support of the transfer belt onto the next press fabric in the press section and/or into the next press nip. In the pre-press zone or zones, a substantial amount of water is removed out of the web substantially in one direction only, and, at the same time, the web is made to adhere reliably to the outside face of the transfer belt.

摘要： A press roll belt is arranged to be used in connection with a roll (10) forming a press nip. The belt (12) of the press roll (10) is provided with a groove pattern formed of intersecting grooves (11A, 11B). A press concept has at least one press nip formed between two rolls (30, 32) to remove water from a web. At least one press nip (NA) of the press concept is formed such that the cover (22) or the belt (12) of at least one roll (30A, 32A) forming the press nip is provided with groove patterning formed of intersecting grooves (11A, 11B; 21A, 21B).
