Abstract
A device for guiding a sheet as it is conveyed through a deliverer or between printing units of a sheet-fed printing machine is provided. The sheet guiding device includes a guide surface which has a plurality of openings therein and a housing which is arranged below the guide surface and which together with the guide surface defines a flow duct. The guiding device also includes a air system which is in fluid communication with the flow duct. At least one flexible hollow seal member is arranged in the flow duct and is adapted such that it can be selectively filled with a fluid medium which expands the seal member into a sealing position wherein it seals off a predetermined portion of the openings in the guide surface from the air system.
