Abstract

Eine Vorrichtung zum Führen einer zu trocknenden Faserstoff-Bahn zusammen mit einem porösen Stützband (15) durch eine Trockenvorrichtung, mit einer Anordnung zum Führen der Bahn und des Stützbandes (5) auf einem im wesentlichen geraden Laufweg von einem heizbaren Trockenzylinder (11), der auf einem Teil seines Umfangs von der Bahn und dem Stützband umschlungen wird und dabei die Bahn berührt, zu einer Umlenkwalze (10), die auf einem Teil ihres Umfangs vom Stützband umschlungen wird und dabei das Stützband berührt, zu einem weiteren Trockenzylinder (12), einem in dem Zwickel zwischen den Trockenzylindern (11,12) und der Umlenkwalze (10) angeordneten, an einen Absaugkanal (18) angeschlossenen Saugkasten (14), der im Bereich der Ablaufstelle (A) vom ersten Trockenzylinder (11) eine Pick-up-Zone aufweist, welche durch eine vor der Ablaufstelle (A) gelegene, sich quer zur Bahnlaufrichtung erstreckende erste Dichtleiste und eine nach der Ablaufstelle gelegene, sich quer zur Bahnlaufrichtung erstreckende zweite Dichtleiste (36) begrenzt und an einen Absaugkanal (3) angeschlossen ist, zeichnet sich dadurch aus, dass die Pick-up-Zone mit einem höheren Unterdruck beaufschlagt ist als der Saugkasten (14).

A device for guiding a fibrous web to be dried together with a porous support belt (15) through a drying device, with an arrangement for guiding the web and the support belt (5) on a substantially straight path from a heatable drying cylinder (11) which is wrapped on part of its circumference by the web and the support belt and thereby touches the web, to a deflection roller (10) which is wrapped on a part of its circumference by the support belt and thereby touches the support belt, to a further drying cylinder (12), a suction box (14) arranged in the gusset between the drying cylinders (11, 12) and the deflecting roller (10) and connected to a suction channel (18), which has a pick-up in the area of the outlet point (A) from the first drying cylinder (11) Zone which has a first sealing strip located in front of the discharge point (A) and extending transversely to the web running direction and a seal strip located after the discharge point and transverse to the Bahnlau The second sealing strip (36), which extends in the direction of the direction of rotation, and is connected to a suction channel (3), is characterized in that the pick-up zone is subjected to a higher vacuum than the suction box (14).
