Abstract

Die Erfindung betrifft einen beheizten Trockenzylinder (4) zur Trocknung einer ihn teilweise umschlingenden Faserstoffbahn (1), insbesondere einer Papier-, Karton- oder Tissuebahn in Maschinen zu Herstellung und/oder Veredelung derselben, wobei ein endlos umlaufendes Band (2) die Faserstoffbahn (1) gegen den Zylindermantel (3) des Trockenzylinders (4) drückt.The invention relates to a heated drying cylinder (4) for drying it partially wrapping fibrous web (1), in particular a paper, cardboard or Tissue web in machines for producing and / or finishing the same, one endless belt (2) the fibrous web (1) against the cylinder jacket (3) of the Drying cylinder (4) presses.

Davon ausgehend soll das Ablösen der Faserstoffbahn (1) bei gleichzeitiger Gewährleistung eines guten Trocknungsergebnisses erleichtert werden.Proceeding from this, the detachment of the fibrous web (1) should at the same time Ensuring a good drying result can be facilitated.

Erreicht wird dies dadurch, daß der Zylindermantel (3) im Kontaktbereich der Faserstoffbahn (1) luftdurchlässig ist und der Innenraum des Trockenzylinders (4) an eine Druckluftquelle (5) angeschlossen ist.

Figure 00000001
This is achieved in that the cylinder jacket (3) in the contact area of the fibrous web (1) is permeable to air and the interior of the drying cylinder (4) is connected to a compressed air source (5).
