Abstract
In a sheet-fed printing press, a contact-free sheet guiding device having a sheet guiding surface is provided including at least one blast air nozzle disposed in the sheet guiding surface and having an air guiding surface directed obliquely downwardly with respect to the sheet guiding surface, the air guiding surface defining a cross section of the blast air nozzle disposed obliquely downwardly from the sheet guiding surface, the blast air nozzle being disposed so that a flow direction of blast air emerging from the blast air nozzle encloses, with the sheet guiding surface, a steep angle directed against the sheet from below, the blast air flow having a vertical directional component which is greater than a horizontal directional component thereof.
