Abstract

A paper or board machine having a double-felted first press nip and a double-clothed second press nip. According to the invention the first press nip has a suction roll (11) with a suction zone (49), the downstream end (51) of which is situated downstream of the press nip, the top felt (15) being separated from the bottom felt (13) at a point (P) before the downstream end of the suction zone. The bottom felt (13) of the first press nip carries the web to the second press (10) which has a top felt (22) which carries the web from the bottom felt (13) of the first press nip to the second press nip, which is an extended press nip. A pickup suction roll (24) is arranged in the top felt loop (22) of the second press (10) for transfer of the web from the bottom felt of the first press to the top felt of the second press (10). The latter bottom felt (13) leaves the suction roll (11) at the downstream end (51) of the suction zone (49) and is provided in its loop with suction boxes (17) situated at a point before the transfer of the web to the top felt of the second press. Heat-supply devices (40) are arranged outside the two top felts at points where one side of the web is exposed and the other side adheres to the top felts.
