Abstract
Device for handling a material web that includes a suction roll having a perforated jacket, and a porous support belt guided over the suction roll between a take-on region and a lift-off region. A surface of the porous support belt is adapted to guide the material web and the surface adapted to guide the material web is arranged away from a surface of the suction roll. The suction roll includes suction zones adjacent to an inner side of the perforated jacket, such that a first suction zone, arranged in the take-on region, is coupled to a vacuum source, and a second suction zone, arranged in the take-off region, is coupled to the vacuum source through the first suction zone. One of an outer web holding box and a suction tube is positioned subsequent to the take-off region, relative to a web travel direction, and is arranged to be suctioned by the second suction zone.
