Abstract
A method and system are provided for aligning the lateral edge of sheets fed to a printing press. The lateral position of a sheet is detected. A slidable suction device beneath the sheet is operated to pull the sheet toward a lateral abutment at a constant speed, the suction being applied at an individual time for each sheet in accordance with the detected position. Suction pressure is released when the sheet reaches the side lay, such that suction pressure is only applied for the time necessary to place the sheet in proper registration.
