Two-wire cylinder dryer

摘要

In a two-wire cylinder dryer, the wire guide rolls are so arranged that the web and wire proceed jointly from the first cylinder to the wire guide roll. An air carrier box is arranged in the shaft contained between two cylinders. The air carrier box has an air channel connecting the area of the leaving point A with an opposite pressure zone. Hot air flows into the air channel through a driver nozzle, so that in the area of the leaving point there is a vacuum zone created which is outwardly bounded by a sealing strip. The pressure zone is bounded by further sealing strips.
