Abstract

Eine Vorrichtung zur Herstellung von Materialbahnen (12) umfasst ein umlaufendes, mit einer bewegten Gegenfläche einen Pressspalt (20) bildendes Pressband (14) sowie mehrere in Bahnlaufrichtung aufeinanderfolgende Durchbiegungseinstellwalzen (22), durch die das umlaufende Pressband (14) im Pressspaltbereich gegen die bewegte Gegenfläche pressbar ist, wobei die Durchbiegungseinstellwalzen (22) jeweils einen umlaufenden Walzenmantel (24), ein den Walzenmantel (24) durchsetzendes drehfestes Joch sowie zwischen dem Walzenmantel (24) und dem Joch angeordnete Anpresselemente (28) umfassen, die auf der dem Pressspalt (20) zugewandten Jochseite vorgesehen sind und über die der Walzenmantel (24) in Richtung des Pressspalts (20) beaufschlagbar ist. Dabei ist zumindest ein Teil der Durchbiegungseinstellwalzen (22) jeweils mit wenigstens einem zwischen dem Walzenmantel (24) und dem Joch angeordneten Gegenelement versehen, das auf der vom Pressspalt (20) abgewandten Jochseite vorgesehen und über das der Walzenmantel (24) in einer Richtung vom Pressspalt (20) weg beaufschlagbar ist.

Figure 00000001
An apparatus for producing webs of material (12) comprises a circumferential press belt (14) which forms a press nip (20) with a moving counter surface and a plurality of web deflection rolls (22) which follow one another in the web running direction, through which the revolving press belt (14) moves in the press nip region Counter surface is pressed, wherein the deflection adjustment (22) each comprise a peripheral roll shell (24), a roll shell (24) passing through a rotationally fixed yoke and between the roll shell (24) and the yoke arranged pressing elements (28) on the said press nip ( 20) facing the yoke side are provided and over which the roll shell (24) in the direction of the press nip (20) can be acted upon. In this case, at least a part of the deflection adjustment rollers (22) is in each case provided with at least one counter element arranged between the roll shell (24) and the yoke, which is provided on the yoke side facing away from the press nip (20) and over which the roll shell (24) in a direction from Pressing gap (20) can be acted upon away.
