Abstract

Die Erfindung betrifft eine Vorrichtung (100) zur Herstellung von Tissuebahnen (T), umfassend eine Vorrichtung (101) zur Entwässerung mit einem endlosen, permeablen strukturierten Band (4) und ein, eine Saugwalze (6) teilweise in Umfangsrichtung umschlingendes endloses permeables Entwässerungsband (5), wobei das permeable strukturierte Band (4) über einen Teilbereich seines Umlaufweges gemeinsam mit dem permeablen Entwässerungsband (5) über zumindest einen Teilbereich des Umschlingungsbereiches (37) des permeablen Entwässerungsbandes (5) mit der Saugwalze (6) unter Ausbildung eines Entwässerungsabschnittes (38) geführt wird und mit Mitteln zum Aufbringen eines Druckes auf die beiden Bänder (4, 5) und die zwischen diesen geführte Tissuebahn (T) in diesem Entwässerungsabschnitt (38). Die Erfindung ist dadurch gekennzeichnet, dass die Mittel eine in Durchlaufrichtung der Tissuebahn (T) betrachtet nur im Einlaufbereich (22) der Bänder (4, 5) in den Entwässerungsabschnitt (38) an der Saugwalze (6) in Umfangsrichtung dieser örtlich begrenzt einen Druck aufbringende Einrichtung (36) umfassen.

The invention relates to a device (100) for the production of tissue webs (T), comprising a device (101) for dewatering with an endless, permeable structured strip (4) and a continuous permeable dewatering strip partially encircling a suction roll (6) ( 5), wherein the permeable structured band (4) over a portion of its circulation path together with the permeable dewatering band (5) over at least a portion of Umschlingungsbereiches (37) of the permeable dewatering belt (5) with the suction roll (6) to form a dewatering section ( 38) and with means for applying a pressure to the two belts (4, 5) and the tissue web (T) guided between them in this dewatering section (38). The invention is characterized in that the means in the direction of passage of the tissue web (T) only in the inlet region (22) of the bands (4, 5) in the dewatering section (38) on the suction roll (6) in the circumferential direction of this locally limited pressure applying means (36).
