ABSTRACT:
In a reversing device of a sheet-fed rotary printing machine, there is provided a suction gripper for taking over a trailing edge of a sheet conveyed on an upline sheet-conveying cylinder, the suction gripper being movable out of a periphery of a downline sheet-conveying cylinder, gripping the sheet to be reversed in a region of the trailing edge thereof, and being movable back in a substantially radial direction towards the downline sheet-conveying cylinder for transferring thereat the trailing edge of the sheet to a further gripper device, including a device for converting the substantially radial return movement of the suction gripper into an axial movement of the suction gripper so as to tauten the sheet.
