Abstract

In a reduced pressure conveyor belt device for guiding a moving sheet (2), with an air-permeable endless transporting belt (5) guided in a loop (8) with upper and lower tracks (6, 7) and a reduced pressure source (9) to fix the sheet to the inside of a track (6), reduced pressure is applied by long gap ejector(s) (10, 11), each having an air jet injector (12) with air outlet nozzles (14) along the inlet side (15, 16) of the long gap (17, 18), under the inside of the sheet fixing track (6).
