Abstract
A method for smear-free guidance of a printed sheet on a given sheet-guiding cylinder of a printing press includes taking over a leading edge of the sheet by a gripper device of the given sheet-guiding cylinder from a preceding or up-line sheet-guiding cylinder and, after the take-over of the leading edge of the sheet by the gripper device, fixing a first section of the underside of the sheet to the circumferential surface of the preceding or up-line sheet-guiding cylinder in a manner that the sheet, which has been pushed onwardly by the preceding or up-line sheet-guiding cylinder, is kept spaced from the circumferential surface of the given sheet-guiding cylinder, and the circumferential surface of the given sheet-guiding cylinder is located, as viewed in radial direction, within a circular path described by the gripper device during the rotation of the given cylinder.
