ABSTRACT:
A self-valving vacuum distribution system for a belt-driven sheet conveyor utilizes the sheets to automatically open vacuum control valves sequentially in a downstream direction as the sheet is carried on the belts. The system also automatically adjusts for varying sheet widths to automatically apply vacuum holding force only to the belt conveyor area covered by the sheet.
