Abstract
An arrangement and method for transferring a paper web in high-speed paper machines having a press section arranged between a web former and a dryer section. In the press section, there is one or more press nip zones dewatering the web, at least the last one of which is preferably an extended nip through which at least two press fabrics that receive water are passed. The web is passed between the press fabrics through the last extended-nip zone so that the draining of water out of the web takes place through both faces of the web. After the last press nip zone, the web follows one of the fabrics passing through the last extended-nip zone by the effect of a difference in pressure avoiding rewetting of the web. The fabric carrying the web is passed through a gently loaded transfer nip zone in which the web is transferred onto a transfer surface more adhesive than the face of the fabric. The web is transferred on this transfer surface as a closed draw onto the drying wire or equivalent in the dryer section following after the press section.
