Zusammenfassung: | Conveying tables for overlapping sheet transport between a feeding device and a printing machine are known, which work with suction air acting through suction bands. The underpressure created in a suction chamber must not, however, fasten, by suction, the printed sheet on the conveying table via spurious air flowing through side regions.
The suction bands 6 are let into the conveying table 3. At the side of the guide grooves 10, ventilation openings 11, 12 are provided, which are connected to the environment separately from the suction chamber. To this end, ventilation ducts are provided, which unite the ventilation openings 11, 12. The perforation in the suction band 6 can be made in the form of slots 14 which are arranged in a mutually offset manner and leave free support regions on the edge and in the centre 16 of the band.
Spurious air caused by band expansion is avoided. The printed sheets are held uniformly on both sides and guided across the conveying table without distortion. |
