Abstract

A machine for producing fiber-containing web material, in particular tissue paper, includes a permeable dewatering belt for transporting fiber-containing source material used for producing web material from a forming section to a suction/pressing section, and a press belt assembly assigned to the suction/pressing section. The source material is received in the suction/pressing section between the press belt assembly and the dewatering belt and the press belt assembly presses the source material and the dewatering belt against a suction assembly of the suction/pressing section. The press belt assembly has a single press belt providing a source material contact surface.
