Abstract

Eine Preßanordnung zur Behandlung einer Materialbahn (1) in mehreren Preßspalten (2, 3) umfaßt eine Walze (4), die einen von innen abgestützten flexiblen Preßmantel (5) besitzt und mit wenigstens zwei weiteren, angetriebenen Walzen (6, 7) jeweils einen Preßspalt (2, 3) bildet. Dabei kann bei einer der angetriebenen Walzen (6) die Antriebsleistung oder die Geschwindigkeit entsprechend einem vorgegebenen Sollwert geregelt sein, um auf einfache Weise insbesondere eine gleiche Geschwindigkeit der angetriebenen Walzen (6, 7) zu gewährleisten. Vorteilhafterweise ist auch eine solche Ausführung möglich, bei der die maximale Linienkraft und/oder die Antriebsleistung eines in Bahnlaufrichtung (8) betrachtet vorderen Preßspaltes (3) zumindest innerhalb eines bestimmten Bereichs in Abhängigkeit von der maximalen Linienkraft bzw. der Antriebsleistung eines in Bahnlaufrichtung (8) betrachtet hinteren Preßspaltes (2) steuer- und/oder regelbar ist.

A press arrangement for treating a material web (1) in a plurality of press nips (2, 3) comprises a roller (4) which has an internally supported flexible press jacket (5) and one with at least two further driven rollers (6, 7) Press nip (2, 3) forms. In the case of one of the driven rollers (6), the drive power or the speed can be regulated in accordance with a predetermined target value, in order in particular to ensure in a simple manner that the driven rollers (6, 7) have the same speed. Such an embodiment is advantageously also possible in which the maximum line force and / or the drive power of a front press nip (3) viewed in the web running direction (8) at least within a certain range as a function of the maximum line force or the drive power of one in the web running direction (8 ) considered rear press nip (2) is controllable and / or adjustable.
