ABSTRACT:
A device for changing an operating state of a gripper-control device in a sheet-reversing device of a sheet-processing machine including a cylinder having an actuating shaft accommodated therein, includes an activating element cooperatively engaging with the actuating shaft for changing the operating state of the gripper control device. An actuating element is coupled mechanically with the actuating shaft. An adjusting element is movable relative to the cylinder. The adjusting element is disposed externally to the cylinder and cooperatively engages with the actuating element for moving the actuating element at least approximately synchronously with the cylinder during operation of the sheet-processing machine while the actuating shaft remains in a prescribed position with respect to the cylinder. The actuating element is changeable in position relative to the cylinder by the adjusting element, whenever the operating state is changed. A sheet-processing machine is provided with the operating-state changing device.
