Abstract

Es wird eine Siebpartie (10) und ein Verfahren zum Entwässern einer Faserstoffbahn in einer Siebpartie einer Papiermaschine angegeben, bei dem eine Faserstoffsuspension (18) aus einem Stoffauflauf (12) zwischen zwei Siebe (14, 16) ausgebracht und entwässert wird, wobei noch vor Erreichen des Immobilitätspunktes die Entwässerungsgeschwindigkeit quer zur Bahnlaufrichtung (11) gesehen in den Randbereichen im Verhältnis zur Mitte der Faserstoffbahn (18) verlangsamt wird, um eine Verbesserung des Formationsquerprofils zu erreichen.
