Abstract

Die Erfindung betrifft ein Verfahren zur Messung und Regelung des Nipdrucks in der Presse einer Papiermaschine, insbesondere in einer Schuhpresse, quer und/oder längs zur Bahnlaufrichtung. Sie ist vornehmlich dadurch gekennzeichnet, dass der hydraulisch statische Druck an Referenzpunkten über Messbohrungen im Pressnip gemessen und laufend angepasst wird. Weiters betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.

The invention relates to a method for measuring and controlling the nip pressure in the press of a paper machine, in particular in a shoe press, transversely and / or lengthways to the web running direction. It is primarily characterized by the fact that the hydraulic static pressure at reference points is measured via measuring holes in the press nip and is continuously adjusted. The invention further relates to a device for carrying out the method.
