Abstract

Die Erfindung betrifft eine Pressanordnung zur Entwässerung einer Papier-, Karton-, Tissue-oder einer anderen Faserstoffbahn (1) in einer Maschine zur Herstellung und/oder Veredelung derselben, bestehend aus zumindest einem, von zwei gegeneinander gepreßten Presswalzen (2,3) gebildeten Preßspalt, durch den neben der Faserstoffbahn (1) wenigstens ein oberhalb (4) und ein unterhalb (5) der Faserstoffbahn (1) verlaufendes Entwässerungsband läuft, wobei die Faserstoffbahn (1) nach dem Preßspalt in einer sich anschließenden Führungsstrecke (6) mit dem oberen (4) und dem unteren (5) Entwässerungsband in Kontakt steht.The invention relates to a press arrangement for dewatering a paper, cardboard, Tissue or another fibrous web (1) in a machine for production and / or refining the same, consisting of at least one, of two press nips pressed against each other (2,3) formed by the next the fibrous web (1) at least one above (4) and one below (5) the Fibrous web (1) running drainage belt runs, the fibrous web (1) after the press nip in a subsequent guide section (6) with the upper (4) and lower (5) drainage belt is in contact.

Davon ausgehend soll der Rückbefeuchtung der Faserstoffbahn (1) bei guter Führung derselben dadurch begegnet werden, daß das untere Entwässerungsband (5) im Bereich der Führungsstrecke (6) über zumindest eine quer zur Faserstoffbahn (1) verlaufende Saugvorrichtung (7) geführt wird, welche mit einer Unterdruckquelle verbunden ist.

Figure 00000001
Proceeding from this, the rewetting of the fibrous web (1) should be countered with good guidance by the fact that the lower dewatering belt (5) is guided in the region of the guide section (6) via at least one suction device (7) running transversely to the fibrous web (1), which is connected to a vacuum source.
