Zusammenfassung:A gripper device for a printing machine for handling sheet-shaped material with a gripper shaft swivellable about its longitudinal axis and a gripper finger firmly connected to the gripper shaft so that a gripper point thereof is movable away from a gripper support when the gripper shaft is swivelled in a first direction, is initially displaceable into contact with the gripper support when the gripper shaft is swivelled in a second direction opposite to the first direction, and is capable of exerting a holding force on the gripper support when the gripper shaft is swivelled farther in the second direction, and a device for adjusting contact between the gripper point and the gripper support includes a resilient section forming a part of the gripper finger and connected to the gripper point, the resilient section having neutral fibers and formed as at least one resilient rod extending substantially in the direction of a plane determined by the longitudinal axis of the gripper shaft and by the gripper point.
