A device for guiding sheet material in a printing press, the device having a guide surface located below a path in which a sheet is guidable, includes nozzles arranged in zones within the guide surface, the zones including a first zone extending along a longitudinal axis of the guide surface, and a second and a third zone, respectively, located at left-hand and right-hand sides of the first zone, the nozzles in the first zone being blast nozzles having a blowing direction with a component extending orthogonally relative to the guide surface, the nozzles in the second and third zones being blast nozzles having a blowing direction extending essentially from the longitudinal axis of the guide surface to lateral edges of the guide surface, the nozzles of the first zone being suppliable with blast air independently of a supply of air to the nozzles of the second and the third zones; and a method of operating the guiding device.
