摘要

The sheet turner, at a sheet-fed rotary printing press, has a gripper system (2.2) at the turner drum for two-sided printing to grasp the leading edge of the sheet at the printing cylinder (1), to pass the trailing edge to the turner drum (2). A doctor blade (5) guides the sheet, positioned to use the gripper (2.1) for one-sided printing or the gripper for printing on both sides.
