Abstract
A method for transferring, by a trailing edge thereof, a sheet conveyed on an upline sheet-conveying cylinder to a gripper device of a downline sheet-conveying cylinder in a reversing device of a sheet-fed rotary printing press, the gripper device having sheet-holding surfaces for accepting the sheet trailing edge, which comprises lifting the sheet by the trailing edge thereof from the upline sheet-conveying cylinder; moving the sheet-holding surfaces of the gripper device out of the periphery of the downline sheet-conveying cylinder; with the sheet-holding surfaces of the gripper device, accepting the sheet trailing edge outside the periphery of the downline sheet-conveying device; and moving the sheet-holding surfaces back into the periphery of the downline sheet-conveying cylinder; and a transferring device for performing the method.
