Abstract

Die Erfindung betrifft eine Pressenpartie zur Entwässerung einer Faserstoffbahn (1), insbesondere einer Papierbahn mit mindestens zwei Preßspalten (2, 3), wobei zumindest der erste Preßspalt (2) von einer Schuhpreßwalze (4) und einer zylindrischen Gegenwalze (5) gebildet wird und die Faserstoffbahn (1) nach einer teilweisen Umschlingung der Gegenwalze (5) des ersten Preßspaltes (2) auf möglichst kurzem Weg zur ebenfalls zylindrischen Gegenwalze (6) des letzten Preßspaltes (3) gelangt.
Davon ausgehend soll die Führung der Faserstoffbahn insbesondere nach dem letzten Preßspalt verbessert werden.
Erreicht wurde dies dadurch, daß zumindest durch den letzten Preßspalt (3) jeweils wenigstens ein beidseitig der Faserstoffbahn (1) angeordneter Preßfilz (7, 8) verläuft und nach dem letzten Preßspalt (3) ein Preßfilz (7, 8) mittels einer Saug- (9) oder Blaselementes (10) von der Faserstoffbahn (1) getrennt und weggeführt wird.
