Sheet transfer between color printing stations has a perforated guide surface to form an air cushion for a clean sheet movement without flutter

摘要

To move sheets between printing stations, in multi-color printing processes, they travel over a guide surface (4.7) in a chain conveyor along the line of movement (4.17). An air cushion is generated between the sheets and the guide surface through alternating surface openings (4.8,4.8') which blow and extract air.
