摘要

Device for depositing printed sheets on a sheet pile, including at least one pair of mechanical grippers for seizing the printed sheets at a respective leading edge thereof, the gripper pair being movable over the sheet pile and being controllable for releasing the printed sheets at a given instant of time, a pneumatic device for applying varying pressure to defined regions over a depositing surface of the respective printed sheets for decelerating and transporting the sheets against a mechanical stop, and adjusting elements for the grippers and the pneumatic device, also includes a control device including a computer and having an input and an output, the control device being connected via the output thereof to the adjusting elements, an input device for receiving sheet-specific and process-specific data being connected to the control device via the input thereof, the sheet-specific and process-specific data including data regarding two-dimensional mass distribution of the respective printed sheet, the adjusting elements of the pneumatic device being controllable by the control device so as to produce a pressure distribution on the depositing surface of the respective printed sheet which is correlated with the mass distribution of the respective printed sheet.
