Claim 17:
18. A process for processing printing individual sheets, the process comprising:
gripping a sheet of the individual sheets by a gripper conveyor running in a transport direction;
transporting, by the gripper conveyor, the gripped sheet along the transport direction, through a processing station;
during the transport through the processing station, supporting a region of the gripped sheet by a support conveyor running in the transport direction; and
during the transport of the support conveyor through a processing region of the processing station, selectively switching a number of connections of a vacuum system of the support conveyor, the connections being arranged along the transport direction,
wherein the gripper conveyor comprises a first gripper conveyor and a second gripper conveyor, and
a leading edge of the gripped sheet is gripped by the first gripper conveyor and a trailing edge of the gripped sheet is gripped by the second gripper conveyor, the support conveyor being arranged between the first gripper conveyor and the second gripper conveyor in the transport direction,
wherein after the gripping, a distance between the first gripper conveyor and the second gripper conveyor is controlled in such a way that a tensioning force is applied to the individual sheet for straightening the individual sheet.
