Abstract

An apparatus for the removal of proof sheets from a sheet-processing machine has at least one sheet catcher provided with a gripper device. The gripper draws the sheet out of the stacking region. A lower sheet catcher is first moved into the stacking region above the sheet stack. Following a deposition of at least one proof sheet, the sheet is gripped with the gripper device, and following sheets are held back with an upper sheet catcher. Then the proof sheet is drawn out of the stacking region by moving the lower sheet catcher and the gripper device back.
