摘要： An air assisted sheet guide device in a printing machine which is operable during either positive pressure (blast) air operation as well as suction air operation to permit reliable and stable sheet guidance with reduced air flow turbulence. The sheet guide device includes at least one module that defines a guide surface having air flow openings therein and an air flow channel, and a pneumatic system for creating either a positive or suction pressure generated air flow in the flow channel. One or more plate-like air directional elements are mounted within the air flow channel which create a uniform pressure distribution on the guide surface during positive (blast) air operation and which more uniformly direct air to the pneumatic system during suction pressure operation.
