Abstract
A method for taking over a sheet by a trailing edge thereof from an upline cylinder of a sheet-fed rotary printing press and transferring the sheet by the trailing edge thereof to a gripper system, by placing a suction gripper on the sheet in a marginal region of the trailing edge and, during the sheet takeover, having the suction gripper follow the periphery of the upline cylinder, having the suction gripper guided at a constant tangent into the periphery of a downline inverting drum and, along this course, having the suction gripper execute a relative motion in the direction of the tangent so as to tauten the sheet, which comprises, upon reaching a transfer position at the gripper system, having the suction gripper execute a relative motion in the sheet transport direction and, when the grippers close, having the suction gripper and the gripper system disposed at rest relative to one another; and a transmission system for performing the method.
