摘要

Device for positioning sheets (2) in the extension arm of a sheet-processing machine, especially a printing machine, comprises a first sheet guiding device (6) arranged below the sheet transport path and loaded with blast air to produce an air cushion supporting the sheets, and a sheet braking device (8). The sheets lie at least in the region of their rear edge under the action of the blast air on a second sheet guiding device (7) arranged above the sheet transport path. The second sheet guiding device guides the sheets relative to the sheet braking device designed as a handling system so that the rear edges of the sheets are picked up by the handling system. Preferred Features: The second sheet guiding device is a rotatably mounted guide drum or guide cylinder.
