Abstract

Es wird eine Pressenanordnung 10 einer Papier- oder Kartonmaschine zur Behandlung einer Faserstoffbahn 12 in einem in Laufrichtung L der Faserstoffbahn 12 verlängerten Preßspalt 14 beschrieben. Der Preßspalt 14 ist durch zwei Preßflächen begrenzt, von denen wenigstens eine durch einen flexiblen, über wenigstens einen Preßschuh 16 geführten Preßmantel 18 gebildet ist, der durch den Preßschuh 16 unter Ausbildung eines Fluidkissens zwischen Preßschuh 16 und Preßmantel 18 gegen die gegenüberliegende Preßfläche preßbar ist. Hierbei ist der Preßschuh so beaufschlagbar, daß sich eine resultierende Hauptpreßkraft einstellt, die in einer Richtung wirkt, die zumindest im wesentlichen senkrecht zur durch den Preßspalt 14 geführten Faserstoffbahn 12 verläuft. Es sind Mittel 28 vorgesehen, um den Preßschuh 16 durch positive und/oder negative Zusatzkräfte zu belasten, die zumindest im wesentlichen senkrecht zur resultierenden Hauptpreßkraft auf den Preßschuh 16 wirken und diesem ein Kippmoment um eine jeweilige Kippachse vermitteln, die sich zumindest im wesentlichen senkrecht zur Laufrichtung L der Faserstoffbahn 12 in Querrichtung der Pressenanordnung 10 erstreckt, so daß durch diese Zusatzkräfte ein sich in Laufrichtung L der Faserstoffbahn 12 im Preßspalt 14 einstellendes Druckprofil zumindest im wesentlichen unabhängig von der resultierenden Hauptpreßkraft beeinflußbar ist.

Figure 00000001
A press arrangement 10 of a paper or board machine for treating a fibrous web 12 in a press nip 14 extended in the running direction L of the fibrous web 12 is described. The press nip 14 is delimited by two press surfaces, at least one of which is formed by a flexible press jacket 18 guided over at least one press shoe 16, which can be pressed by the press shoe 16 to form a fluid cushion between the press shoe 16 and the press jacket 18 against the opposite press surface. In this case, the press shoe can be acted on in such a way that a resulting main press force is set, which acts in a direction which is at least substantially perpendicular to the fibrous web 12 guided through the press nip 14. Means 28 are provided to load the press shoe 16 by positive and / or negative additional forces which act at least substantially perpendicular to the resulting main press force on the press shoe 16 and impart a tilting moment about a respective tilt axis which is at least substantially perpendicular to the press shoe 16 Running direction L of the fibrous web 12 extends in the transverse direction of the press arrangement 10, so that a pressure profile which is established in the running direction L of the fibrous web 12 in the press nip 14 can be influenced at least essentially independently of the resulting main pressing force by these additional forces.
