Abstract

The machine has a press section with single-felt-press nips (N1, NP1) formed between a suction press roll (11) and a central roll (31) and between the central roll and a press roll e.g. flat nip roll (41), respectively. A metal coil loop (30) is arranged at the central roll, and web (W) is brought in the nip (N1) for adhesion at surface of the loop. The loop is formed by an airtight metal band that is heated by a heating device (32). A mesh running around a transfer suction roll (51) is formed as a transfer sieve (50), where the web is supportably transported from the mesh into the machine. An independent claim is also included for a method for producing a material web.
