    摘要: 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.

    摘要: 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.
