  • Patent number: 5599013
    Abstract: A printing machine has side frames and a printing machine drive. A paper sheet guiding cylinder is mounted in the side frames of the printing machine, is drivingly connected to the printing machine drive and has an axis. The paper sheet guiding cylinder includes a cylindrical casing and side walls with through holes formed therein. The paper sheet guiding cylinder has a rotatably mounted radial ventilator being coaxial with the axis of the paper sheet guiding cylinder for supplying blowing air into the paper sheet guiding cylinder and for deflecting the blowing air inside the paper sheet guiding cylinder towards the cylindrical casing. The radial ventilator has end surfaces communicating with the ambient air through the holes and ventilator blades being disposed concentrically about the axis of the paper sheet guiding cylinder and extending along the paper sheet guiding cylinder. A drive for the paper sheet guiding cylinder has adjustable speed and is independent of the paper sheet guiding cylinder.

  • Patent number: 5568919
    Abstract: A delivery of a sheet-processing machine for transporting a sheet along a sheet-conveying path to a stacking device, includes a sheet braking device engaging, during operation, with an underside of a sheet and retarding it by suction belts or the like. A suction region is adjacent to and upstream of the sheet braking device. A suction device applies suction, in the suction region, to the underside of the sheet. A brake carriage carries the sheet braking device and the suction device and is displaceable between selective positions within a segment of the path. A stationary first guide device has a first sheet guide surface segment set back upstream from the sheet braking device. A second guide device has a guide element displaceable by the brake carriage and forming a second sheet guide surface segment between the sheet braking device and the first sheet guide surface segment. The second segment, together with the first segment, form a combined sheet guide surface having a telescopically variable length.
