Abstract
A multi-nip press portion or section of a paper or cardboard machine wherein a web is detached from a forming wire by a pick-up roller and transferred onto a first fabric which carries the web into the first nip and wherein the press section includes at least two water-removing press nips which include a common smooth-surface central roller. The central roller has a downwardly facing open sector with which a scraper is associated for passing the web in the case of a break to a pulper or the like. The first nip, which can constitute a press nip and/or a transfer nip is formed by a counter-roller situated in nip-defining relationship with the pick-up roller. A second fabric passes through the first nip over the counter-roller and carries the web on its upper face from the first nip to a second double-fabric nip through which the second fabric, constituting a lower fabric, and a third fabric, constituting an upper fabric pass. The third fabric has a substantially vertical run on which the web is carried from the second nip to a third nip defined by a press roller and the smooth-surfaced central roller. After passing through the third nip, the web separates from the third fabric and follows the surface of the central roller to either a following nip or nips or to a web detachment point.
