摘要： A tissue papermaking machine is described, comprising a wet section (2) and a press section (3) comprising a single press (11) with first and second press elements (12, 13) forming a press nip (N1), and with a press felt (17) running through the press nip in contact with the formed fibre web (1′), whereby the second press element is arranged inside the loop of the press M felt, and a smooth belt (14) runs through the press nip in contact with the formed fibre web, whereby the first press element is arranged inside the loop of the belt, and a transfer roll (16) arranged inside the loop of the belt forming a transfer nip (N2) with a drying surface (20), whereby the smooth belt carries the fibre web between the press nip and the transfer nip. Furthermore, the machine has a dry section (4) for final drying of the fibre web (1″). According to the invention, a pre-dewatering device (25) is arranged upstream of the press to dewater the fibre web to a dry content of 15-30%, before the fibre web runs into the press nip, and the press felt and the smooth belt, which is impermeable to water, are arranged to be separate from each other immediately after the exit of the press nip and define there between an angle α, which is at least 5°, to prevent rewetting of the fibre web. The invention also relates to a method of manufacturing a tissue paper web therein and a method of lowering the energy requirement therein.
