ABSTRACT OF THE DISCLOSURE A press section of a paper machine, and method for pressing a web therein, with separate press nips being formed between respective pairs of press rolls, each roll disposed opposite another. An elastic resilient belt substantially thicker than a fabric passing through a press nip, is disposed to run through the same nip, whereby the nip is lengthened and compression impulse usable therein is increased. The paper web is also passed as a closed draw through the successive press nips in the press section, from a pick-up point to a sub- sequent transfer point thereof. Additionally, a transfer belt passes through at least one of the press nips, whereby a closed draw is obtained between two subsequent press nips and/or between a final press nip and a drying section of the paper machine.
