Patent ID: 6848363

Claim:
A device for changing an operating state of a gripper-control device in a sheet-reversing device of a sheet-processing machine, the sheet-reversing device including a first cylinder having an actuating shaft accommodated therein, the actuating shaft being rotatably mounted coaxially with an axis of rotation of the first cylinder, the sheet-processing machine including a second cylinder, the operating-state changing device comprising: an activating element cooperatively engaging with the actuating shaft for changing the operating state of the gripper control device; an actuating element coupled mechanically with the actuating shaft; and an adjusting element movable relative to the first cylinder, said adjusting element being disposed externally to the first cylinder and cooperatively engaging with said actuating element for moving said actuating element at least approximately synchronously with the first cylinder during operation of the sheet-processing machine with the actuating shaft remaining in a prescribed position with respect to the first cylinder, said adjusting element serving for changing a position of said actuating element relative to the first cylinder whenever changing the operating state; said actuating element and said adjusting element being respective first and second mutually meshing gearwheels, said first gearwheel being connected to the actuating shaft, and said second gearwheel being in drive connection with the second cylinder of the sheet-processing machine; said second gearwheel being disposed coaxially with the second cylinder and being connected to the second cylinder so as to be fixed against rotation relative to the second cylinder.
