Abstract
Die Erfindung ist dadurch gekennzeichnet, daß eine der beiden Trennlamellen starr ausgebildet (4) ist und die andere Trennlamelle mit einem Gelenk (5) versehen ist.
Das erfindungsgemäße Verfahren enthält die folgenden Merkmalen:
- es werden über die Maschinenbreite hinweg mit Hilfe eines Dreischichtenstoffauflaufes drei unterschiedliche Suspensionsströme erzeugt;
- die drei Suspensionsströme werden unmittelbar vor oder beim Auftreffen auf das Sieb zusammengeführt;
- die Geschwindigkeiten der Suspensionsströme werden so eingestellt, daß die Geschwindigkeit des Suspensionsstromes der Außenschicht größer ist als die der Innenschicht.
