Abstract

Vorrichtung zur Entwässerung eines Stoff-Wasser-Gemisches, insbesondere als Teil einer Papiermaschine, mit einer ersten Walze (1), insbesondere Formierwalze, und einer zweiten als offene Walze ausgebildeten Walze (2), insbesondere Brustwalze, deren Mantelflächen einander in einem Abstand (d) gegenüberliegen, einem ersten Sieb (3), welches um die erste Walze (1) herumgeführt ist, und einem zweiten Sieb (4), welches um die zweite Walze (2) und anschließend um die erste Walze (1) herumgeführt ist, so daß zwischen den Sieben (3, 4) ein Formierspalt (5) ausgebildet ist, und einer Vorrichtung zur Zuführung eines Stoff-Wasser-Gemischstrahles (6) zu dem Formierspalt (5). Durch die Vorrichtung wird die Entwässerung bei Doppelsiebformern verbessert.

Device for dewatering a substance-water mixture, in particular as part of a paper machine, with a first roller (1), in particular a forming roller, and a second roller (2), in particular a breast roller, whose outer surfaces are at a distance from one another (i.e. ), a first screen (3), which is guided around the first roller (1), and a second screen (4), which is guided around the second roller (2) and then around the first roller (1), so that a forming gap (5) is formed between the screens (3, 4), and a device for supplying a substance-water mixture jet (6) to the forming gap (5). The device improves dewatering in twin wire formers.
