  • Patent number: 8561987
    Abstract: 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.
