Abstract

Die Erfindung betrifft eine Vorrichtung zum Trocknen einer Faserstoffbahn in einer Zwei-Sieb-Trockenzylinder-Anordnung mit jeweils einem den zwischen den Trockenzylindern (4,5) angeordneten Siebleitwalzen (6) zugeordneten Luftleitkasten (11).
Aufgabe der Erfindung ist es die Vorrichtung dahingehend zu verbessern, daß gelegentlich in den Schacht zwischen den Trockenzylindern (4,5) gelangende Papierfetzen oder sonstige Fremdkörper selbsttätig wieder aus dem Schacht entfernt werden.
Erreicht wird dies dadurch, daß eine nahe der Ablaufstelle des Siebes (8) von der Walze (6) am Mantel der Walze (6) anliegende Längsdichtleiste (17) nach Art einer Klinge ausgebildet ist.
