ABSTRACT:
A device for transporting sheets to a sheet processing machine includes a feed table, and at least one suction belt endlessly revolvable over the feed table. The suction belt is subjectible to vacuum from suction regions of different pressure levels disposed behind one another in a direction of sheet transport and the suction regions are producible by a single vacuum source. The suction belt is formed with through openings, and the feed table is formed with suction openings and ventilation openings, both of which correspond with the through openings formed in the suction belt.
