Abstract

Ein Doppelsieb-Former zur Herstellung einer Papierbahn aus einer Faserstoffsuspension hat zwei Siebbänder (Untersieb 11 und Obersieb 12), die miteinander eine Doppelsiebzone bilden. In einem ersten Abschnitt der Doppelsiebzone, in dem die beiden Siebbänder (11, 12) über eine Formierwalze (30) laufen, bilden die beiden Siebbänder unmittelbar an der Formierwalze miteinander einen keilförmigen Einlaufspalt (28), der unmittelbar von einem Stoffauflauf (26) die Faserstoffsuspension aufnimmt. In einem zweiten Abschnitt der Doppelsiebzone laufen die beiden Siebbänder (11, 12) mit der dazwischen sich bildenden Faserstoffbahn über weitere Entwässerungselemente (36, 37). Wesentlich ist, daß die Doppelsiebzone unmittelbar ausgehend von der Formierwalze (30) steil nach unten verläuft.
