A sheet-fed printing machine contains a printing unit, a drier, and a sheet handling device for transporting or guiding print sheets. The sheet handling device has an opening disposed downstream of the drier in the direction of transport. A humidification device for rehumidifying the print sheets is disposed in such a way that it rehumidifies the print sheets through the opening. The sheet handling device may contain a guide plate or several guide plates.

The invention relates to a machine for processing sheets, having a deliverer for delivering the sheets which comprises a delivery drum that is acted on pneumatically. The delivery drum has vacuum applied to it. The delivery drum also has disks for carrying the sheets, each of the disks defining vacuum channels for holding the sheets. The vacuum channels have openings and a vacuum connection. The openings and the vacuum connection together form a rotary valve cyclically applying vacuum to the vacuum channels.
