Abstract
A conveying device for sheet-like workpieces having low specific gravity (21), such as paper or cardboard, comprises two median conveying elements (11, 12) arranged side by side along the path of the workpieces (21), for changing the orientation of the sheets or plates about a perpendicular axis. Separate drive mechanisms with adjustable speed (18) are connected to each of the median conveying elements (11, 12). A plenum (22) provided with a fan (23) is used to apply a downward air pressure to the workpieces (21), pressing them against the median conveying elements (11, 12) in order to transmit different speeds to each of the surface parts of the workpieces (21) in contact with the respective conveying elements (11, 12).
