摘要： A sheet guide apparatus for use in a rotary printing press which is adapted for the smear and mark free transfer of sheets between two sheet holding and transfer systems, such as a pair of sheet-carrying cylinders or a sheet-carrying cylinder and circulating sheet conveyor. The sheet guide apparatus includes a sheet guide having a guide surface disposed beneath the transfer area, and a pneumatic system for blowing a positive pressure air stream in the direction of a transfer area or tangent point between the sheet holding and transfer systems. A further pneumatic system optionally may be provided for drawing or blowing air through apertures in the guide surface.
