Abstract
In a sheet feed bench with two parallel sheet feed rails that are adjustable relative to one another and with each having blowing jets on their surfaces facing one another directly above the level of the bench, connected to a common source of compressed air, the sheet feed rails resting on the bench surface are provided with groove-like or notch-like enlargements at the level of the blowing jets. Each of these extend over the entire length of the sheet feeder rails. These enlargements make it possible to position the inner surfaces of the sheet feeder rails so closely and tightly against the longitudinal edges of the stack of sheets that only small amounts of compressed air can escape upward. The formation of an air cushion is improved by this in such a way that the stack height can be more than double without adversely affecting the single-sheet separation.
