ABSTRACT:
A sheet-guiding device in a sheet-processing machine, in particular a sheet-fed rotary printing press, includes gripper devices disposed on revolving components of the sheet-processing machine for guiding the sheets to be printed on an air cushion formed by blast air. A multiplicity of free jet nozzles, disposed radially outside a path of movement of the gripper devices, form the air cushion. The free jet nozzles serve for producing free air jets tangentially delimiting an optimized path of movement of the sheets. The optimized path of movement extends in the vicinity of the path of movement of the gripper devices.
