Abstract

Eine Dichtungseinrichtung 10 zur seitlichen Abdichtung wenigstens einer an eine bewegte Fläche 12 angrenzenden Überdruck- oder Unterdruckzone S1, S2 in einer Papiermaschine umfaßt wenigstens ein der bewegten Fläche 12 gegenüberliegendes Dichtelement 14, einen diesem zugeordneten Halter 16, in dem das Dichtungselement 14 in Richtung auf die bewegte Fläche 12 zu und von dieser weg bewegbar gelagert ist, und wenigstens ein Belastungselement, durch das das Dichtelement 14 in Richtung auf die bewegte Fläche 12 zu belastbar ist. Zusätzlich ist wenigstens ein Rückstellelement 20 vorgesehen, durch das das Dichtelement 14 entgegen der Wirkrichtung des Belastungselements 18 von der bewegten Fläche 12 weg beaufschlagbar ist, wobei ein sich im Betrieb zwischen dem Dichtelement 14 und der bewegten Fläche 12 ergebender Dichtspalt 40 über das Rückstellelement 20 und/oder das Belastungselement 18 vorgebbar ist.
