ABSTRACT:
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.
