ABSTRACT:
A first endless felt belt (43) which absorbs water from the belt (9) passes through a first press nip (1) having a stone roll (42C) and a similar second felt belt (57) passes through a second press nip (II). The arrangement is such that the web (9) is continuously in contact with at least one transport means (for instance, with one of the felt belts). One side of the web comes into contact with the stone roll (42C) in the first press nip (I) and the other side of the web comes into contact with the water impermeable elastic press element (53) in the second press nip (II).
