DEVICE FOR TURNING SHEET-LIKE SUBSTRATES

摘要

The present invention relates to a turning unit (14) for sheet-like substrates (6) with at least one first turning element (20), (24) with a basic body having an outer, round substrate contact surface for deflecting the substrate. The deflection is from a first sheet conveying direction to a second sheet conveying direction describing a predetermined angle to the first sheet conveying direction. Furthermore, a channel structure is provided that is formed in the substrate contact surface and onto which open a plurality of gas outlet openings which are in fluid communication with a gas supply.
