Abstract

Die Erfindung betrifft eine Pressanordnung zur Entwässerung einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn (1) in einer Maschine zur Herstellung und/oder Veredlung derselben mit einer Zentralwalze (3), die mit zwei Gegenpresseinheiten zwei Pressspalte bildet, wobei die Gegenpresseinheiten von einem wasseraufnehmenden Entwässerungsband (8,9) und die Zentralwalze (3) von einem Zentralband (2) umschlungen sind.The invention relates to a press arrangement for dewatering a paper, cardboard, tissue or another fibrous web (1) in a machine for producing and / or finishing the same with a central roll (3), which forms two press nips with two counterpressure units, wherein the Counterpressure units of a water-absorbing dewatering belt (8,9) and the central roller (3) by a central band (2) are looped.

Dabei soll die Zweiseitigkeit der Faserstoffbahn (1) dadurch vermindert werden, dass das Zentralband (2) eine Rauhigkeit von mindestens 2 Mikrometer aufweist.

Figure imgaf001
In this case, the two-sidedness of the fibrous web (1) should be reduced by the fact that the central band (2) has a roughness of at least 2 microns.
