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 zumindest zwei Pressspalten, von denen wenigstens der erste verlängert ausgeführt ist und eine Länge von wenigstens 100 mm hat, wobei der erste Pressspalt in Bahnlaufrichtung (14) länger als der letzte Pressspalt ausgebildet ist und die Faserstoffbahn (1) gemeinsam mit zumindest einem wasseraufnehmenden Entwässerungsband (2,3,4) durch die Pressspalte läuft.The invention relates to a pressing arrangement for dewatering a paper, board, tissue or another fibrous web (1) in a machine for producing and / or finishing the same with at least two press nips, of which at least the first is made extended and a length of has at least 100 mm, wherein the first press nip in the web running direction (14) is formed longer than the last press nip and the fibrous web (1) runs together with at least one water-absorbing dewatering tape (2,3,4) through the press nip.

Dabei soll eine volumenschonende Entwässerung bei möglichst ebenen Feuchtequerprofil dadurch erreicht werden, dass die Linienlast im ersten Pressspalt höher als im letzten Pressspalt und der Spitzendruck im ersten Pressspalt geringer als im letzten Pressspalt ist.

Figure imgaf001
In this case, a volume-sparing drainage is to be achieved with flat as possible moisture profile that the line load in the first press nip is higher than in the last press nip and the peak pressure in the first press nip less than in the last press nip.
