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 16 derart beaufschlagbar, daß insbesondere bei einer zumindest im wesentlichen gleichbleibenden durchschnittlichen Gesamtbelastung des Preßschuhs 16 der sich ergebende Kraftschwerpunkt relativ zum Preßschuh 16 in Laufrichtung L der Faserstoffbahn 12 verstellbar und damit das sich in Laufrichtung L der Faserstoffbahn 12 im Preßspalt 14 einstellende Druckprofil entsprechend beeinflußbar ist. Zusammen mit der zu behandelnden Faserstoffbahn 16 wird wenigstens ein Entwässerungsfilz 28 durch den Preßspalt 14 geführt. Zudem ist wenigstens eine Einrichtung 30 zur Steuerung und/oder Regelung des Druckprofils vorgesehen, durch die die jeweilige Lage des relativ zum Preßschuh 16 in Laufrichtung L der Faserstoffbahn 12 verstellbaren Kraftschwerpunkt in Abhängigkeit von wenigstens einer Eingangsgröße Ei einstellbar ist, die für die Beschaffenheit und/oder das Verhalten des Entwässerungsfilzes 28 während des Betriebs repräsentativ ist, so daß die relative Lage des Kraftschwerpunkts bei sich während des Betriebs und im Verlauf der Lebensdauer des Entwässerungsfilzes 28 ergebenden Änderungen der Beschaffenheit bzw. des Verhaltens dieses Entwässerungsfilzes 28 entsprechend verstellbar ist. 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. Here, the press shoe 16 can be acted on such that, in particular with an at least substantially constant average total load on the press shoe 16, the resulting center of gravity is adjustable relative to the press shoe 16 in the running direction L of the fibrous web 12 and thus that which occurs in the running direction L of the fibrous web 12 in the press nip 14 Pressure profile can be influenced accordingly. At least one dewatering felt 28 is passed through the press nip 14 together with the fibrous web 16 to be treated. In addition, at least one device 30 for controlling and / or regulating the pressure profile is provided, by means of which the respective position of the center of gravity, which is adjustable relative to the press shoe 16 in the running direction L of the fibrous web 12, can be set as a function of at least one input variable E i which is suitable for the properties and / or the behavior of the drainage felt 28 during operation is representative, so that the relative position of the center of gravity can be adjusted accordingly during changes in the nature or behavior of this drainage felt 28 during operation and in the course of the life of the drainage felt 28.
