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.

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.

Abstract: An apparatus for ejecting sheets from a sheet transport path onto an auxiliary stack disposed upstream of a main stack, includes a planar sheet guide surface having a sheet ejection opening formed therein. The sheet ejection opening is closed by a sheet separating element and a flap, in a closed state. The separating element and the flap also serve as guide elements during the ejection of sheets.

Abstract: A device for unrolling sheets, with positively guided leading edges, travelling along a conveying path of a delivery of a printing machine for processing the sheets, the sheet unrolling device being formed with a first unrolling groove followed upline in the conveying direction by at least one second unrolling groove, and having a negative-pressure generator for subjecting a respective unrolling groove to negative pressure, includes a delaying device for delaying a negative-pressure increase in the second unrolling groove relative to a negative-pressure increase in the first unrolling groove; and a delivery of a printing machine combined with the sheet-unrolling device.

Abstract: Method of introducing an auxiliary sheet pile carrier above a main sheet pile to be removed, the introduction being effected during uninterrupted feeding of additional sheets above the main sheet pile in a sheet travel direction and in synchronism with the travel of a sheet to be deposited, includes controlling respective drives at a sheet delivery by a control device which determines actual data of a printing press, so that the auxiliary pile carrier traverses a velocity profile identical with a velocity profile of the sheet to be deposited in order to avoid relative movement between the auxiliary pile carrier and the sheet to be deposited.

Abstract: A method of controlling the secretion of sebum in humans which comprises administering to a sensitized human an adjuvant agent selected from 5-fluorouracil and uracil in an amount sufficient to reduce the secretion of sebum produced.

Abstract: A method for the immuno-therapeutic control and treatment of acne by administering an effective amount for treatment of an immunological preparation comprising an immunogen and at least one anti-mitotic adjuvant agent together with a pharmaceutically acceptable carrier.
