Method for guiding sheet material in processing machine e.g. sheet-fed rotary printing machine, involves controlling air supplied through flow nozzles of pneumatic unit by valve

摘要

The sheet material in the conveying direction (5) is supported by the pneumatic support provided by a pneumatic unit. The air supplied through the flow nozzles of the pneumatic unit is controlled by a valve. The distance between the nozzle and the guided sheet material is detected, and the valve is driven based on the detected distance. An independent claim is included for sheet transport device.
