Abstract

Die Entwässerungseinrichtung besteht aus zwei parallelen Walzen 1 und 2, von denen die erste Quernuten, also zur Walzenachse parallele Nuten 21 und die zweite, hohl ausgeführte Walze 2 Ent­ wässerungsbohrungen 18 in ihrem Mantel aufweist. Dadurch kann zwischen dem Siebband 6 und der Oberfläche der ersten Walze 1 eine relativ große Stoffmenge eingebracht werden und die Entwäs­ serungsleistung der zweiten Walze 2 auch erhöht werden.
