Sheet delivery for a sheet-processing machine includes a conveyor system for transporting sheets successively and for releasing the sheets above a sheet pile having a horizontal surface, and a plurality of ventilators or air blowers having a controllable output, the ventilators being disposed in an array above the horizontal surface of the sheet pile for directing blown air from above the sheet pile towards respective oncoming sheets successively transported by the conveyor system and released thereby above the sheet pile, the ventilators being high-speed ventilators constructed for small air volumes and blowing, at a high flow rate, a concentrated air jet with laminar flow substantially vertically from above against the respective oncoming sheets.
