The machine includes a press section, for dewatering the fibrous web, with a press nip, a former, located before, relative to a web travel direction, the press section for sheet formation, and a dryer section, located after the press section for drying the fibrous material web including a first dyer section having no more than three dryer cylinders. Two press rolls are arranged to form the press nip, and at least one press felt is located on each surface of the material web, such that the material web and the at least one press felt on each side of the material web are guided through the press nip. The fibrous material web is dewatered in the former to a dry content of at least approximately 18 %, partially loops around the no more than three dryer cylinders, and is constantly supported from the former to an end of the first dryer group. This arrangement permits the provision of a small but efficient, low cost machine.
