Abstract

Bei einem Verfahren und einer entsprechenden Vorrichtung zur Entwässerung einer Faserstoffbahn (12), insbesondere einer Papier- oder Kartonbahn, wird die Faserstoffbahn (12) durch eine Entwässerungszone (E) geführt, in der sie zumindest teilweise durch eine Beaufschlagung mit unter Druck stehendem Verdrängungsgas (14) entwässert wird. Dabei wird die Faserstoffbahn (12) innerhalb der Entwässerungszone (E) nacheinander durch mehrere Gasdruckimpulse (141 - 144) beaufschlagt.

Figure 00000001
In a method and a corresponding device for dewatering a fibrous web (12), in particular a paper or cardboard web, the fibrous web (12) is guided through a dewatering zone (E), in which it is at least partially exposed to pressurized displacement gas ( 14) is drained. The fibrous web (12) within the dewatering zone (E) is acted upon in succession by several gas pressure pulses (14 1 - 14 4 ).
