  • Sheet-fed printing machine with a humidification device
    Patent number: 11014377
    Abstract: 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.

  • Device for the transport of sheets by means of a chain-driven gripper bar
    Patent number: 7891660
    Abstract: In a device for the transport of sheets in a sheet-processing machine, preferably a printing press, provision is made to transport the sheets on chain-guided gripper bars. The gripper bars are fixed respectively to two chain links arranged indirectly beside each other. The forces acting on the gripper bars are more evenly distributed.

  • Method and delivery for a sheet-processing machine
    Patent number: 7823881
    Abstract: A method of depositing sheets coming out of a sheet-processing machine includes decelerating the sheets and depositing the sheets of a main pile. Certain sheets are decelerated and fed to a second sheet pile. The system includes a device for decelerating the sheets arriving from the sheet-processing machine and for depositing the sheets on a main pile. A chain gripper system is configured to hold and decelerate a trailing edge of the sheets. The chain gripper system includes an adjustable gripper opening cam.
