The invention relates to a storage drum in turning drives of sheet-printing machines. It is an object of the invention to change the relative angular position of sheet-holding positions at a storage drum in turning devices with little expense and simple means. Pursuant to the invention, this objective is accomplished owing to the fact that sheet-holding systems (8, 9) are provided at the storage drum for taking hold of the sheets (7) in the front and rear regions, the sheet-holding systems (8, 9) can be adjusted relative to one another in the circumferential direction, the sheet-holding systems (8) for the front region of the sheet at the basic body (12) and the sheet holding systems (9) for the rear region of the sheet is assigned to a central axis (13), which is taken up by the basic body (12) and the sheet-holding systems (8, 9) are connected to one another by a clutch (18, 20), which can be released by means of the oil of an oil-under-pressure connection (29, 30, 31, 32).

1. A storage drum in a turning device of a sheet-fed printing machine for alternately printing sheets either in recto printing mode or recto and verso printing mode, said storage drum comprising a basic body, a central axis and sheet holding systems, wherein said sheet-holding systems are provided at said storage drum for taking hold of front and rear regions of said sheets; wherein said sheet-holding systems can be adjusted relative to one another in circumferential direction; wherein said sheet-holding system for said front regions of said sheets is assigned to said basic body, and said sheet holding system for said rear regions of said sheets is assigned to said central axis, which is within said basic body, and a clutch for connecting said sheet-holding systems to one another, said connecting element can be disconnected by releasing an oil-under-pressure connection. 2. The storage drum of claim 1, wherein said sheet-holding systems comprise a gripper element and a suction element. 3. The storage drum of claim 1, wherein said clutch comprises a hub and a clutch ring, said hub being disposed non-rotationally on said central axis, said clutch ring being seated in a press fit on said hub, and a pipeline for oil under pressure leading to said press fit. 4. The storage drum of claim 1, wherein said oil-under-pressure connection comprises a pump, a directional control valve, a rotation initiation and a pipeline for oil under pressure. 5. The storage drum of claim 3, wherein said clutch ring is assigned to a gear ring over a stop plate and a cylindrical pin, said cylindrical pin being securely disposed at said gear ring. 6. The storage drum of claim 1, wherein said sheet-holding systems are adjusted relative to one another over a main wheel pull which includes a double gear wheel. 7. The storage drum of claim 2, wherein said suction system can be arrested by a first braking device engaging said central axis when said sheet-holding systems art adjusted relative to one another. 8. The storage drum of claim 1, wherein said sheet-holding systems arc adjusted relative to one another by a motor, which engages said central axis. 9. The storage drum of claim 2, wherein said gripper system can be arrested by a second braking device engaging a tubular extension when said sheet-holding systems are adjusted relative to one another.
