Claim:
A sheet-processing machine, comprising: at least one processing station being a printing unit; a stacking station for holding a stack formed from processed sheets and disposed downstream of said printing unit; a delivery with an endless conveyor transporting the processed sheets in a direction of the stack and disposed downstream of said printing unit; after-grippers following an annular after-gripper path during operation for taking over the processed sheets from said endless conveyor and releasing the processed sheets over the stack; an after-gripper bar having said after-grippers disposed thereon; a mechanism guiding said after-gripper bar together with said after-grippers along said annular after-gripper path, said mechanism being set to positions correlating with different formats of the processed sheets; said endless conveyor and said mechanism having a torque-transmitting connection with each other, said torque-transmitting connection being a flexible drive having an endless flexible drive unit acting on said mechanism; and a drive actuating said mechanism, said drive keeping said mechanism at one and the same phase angle with respect to said printing unit in each of the positions.
