Abstract

Eine Pressenanordnung zur Behandlung einer Faserstoffbahn 10 wie insbesondere einer Papier- und/oder Kartonbahn umfaßt einen zwischen einer Schuhpreßeinheit 12 und einer Gegenwalze 14 gebildeten, in Bahnlaufrichtung L verlängerten Preßspalt 16 und einen zwischen der Gegenwalze 14 und einer weiteren Walze 18 gebildeten Walzenspalt 20. Die Schuhpreßeinheit 12 umfaßt ein um einen drehfesten Träger 22 umlaufendes, im Bereich des verlängerten Preßspaltes 16 durch wenigstens ein Stützelement 24 an dem Träger 22 abgestütztes flexibles Preßband 26. Die Gegenwalze 14 ist als Durchbiegungsausgleichswalze mit einem um einen drehfesten Träger 28 umlaufenden Walzenmantel 30 ausgebildet, der im Bereich des verlängerten Preßspaltes 16 wieder durch wenigstens ein Stützelement 32 an dem betreffenden Träger 28 abgestützt ist. Die vorzugsweise druckfluidbetätigten Stützelemente 24, 32 sind so ausgelegt und beaufschlagbar, daß sich bezüglich der durch die Stützelemente 24, 32 erzeugten, auf das flexible Preßband 26 der Schuhpreßeinheit 12 bzw. den Walzenmantel 30 der Gegenwalze 14 wirkenden inneren Anpreßdrücke ein Differenzdruck einstellt. Dabei ist der Differenzdruck veränderbar.

A press arrangement for treating a fibrous web 10, such as in particular a paper and / or cardboard web, comprises a press nip 16, which is formed between a shoe press unit 12 and a counter roller 14 and is elongated in the web running direction L, and a nip 20 formed between the counter roller 14 and a further roller 18 Shoe press unit 12 comprises a flexible press belt 26, which rotates around a non-rotatable carrier 22 and is supported in the region of the extended press nip 16 by at least one support element 24 on the carrier 22 in the region of the extended press nip 16 is again supported on the carrier 28 in question by at least one support element 32. The preferably pressurized fluid-actuated support elements 24, 32 are designed and can be acted upon such that a differential pressure is established with respect to the internal contact pressures generated by the support elements 24, 32 and acting on the flexible press belt 26 of the shoe press unit 12 or the roller jacket 30 of the counter-roller 14. The differential pressure can be changed.
