The invention relates to an arrangement of sheet-holding systems at storage drums in turning devices of sheet-fed printing machines. It is an object of the invention to provide an arrangement of sheet-holding systems at storage drums, which ensures a stiff construction of the storage drum and a simple adjustment of the sheet-holding systems relative to one another. Pursuant to the invention, this objective is accomplished owing to the fact that sheet-holding systems (8, 9) are provided in the front and rear regions for taking hold of the sheet (7) and can be adjusted relative to one another in the circumferential direction and the sheet holding systems (8) are assigned to the basic body (11) of the storage drum (5) for the front region and the sheet-holding systems (9) are assigned to a central axis (4), which can be fixed and rotated relative to the basic body (11) of the storage drum (5) for the rear region and the central axis (14 is connected with the sheet-holding system (9) by the side disk (17) of the basic body (11) of the storage drum (5).
