发明名称 Press-section for manufacturing paper or paperboard in a continuous web comprises a web-stabilizing device with two air-deflectors
摘要 A press-section comprises a web-stabilizing device with two air-deflectors (14) which are arranged to deflect the air flows away from the wedge-shaped space (9) defined by the press felts (5, 7). A press-section comprises double-felted press (2) with first and second press elements (3, 4), forming a press nip, and first and second press felts running through the press nip. It also comprises a web-stabilizing device that eliminates axial air flows that are detrimental to the stability of the web and which are caused by a partial vacuum arising in the press after the press nip. The device has two air-deflectors on the tender and drive sides outside the side openings of a wedge-shaped space defined by the press felts. The air-deflectors are arranged to deflect the airflows away from the wedge-shaped space by the press felts.
