摘要:
A folding device includes a first partial cylinder and a second partial cylinder. These two partial cylinders form a cylinder body. The two partial cylinders are rotatable relative to each other and each partial cylinder includes first and second groups of functional elements distributed around the circumference of the partial cylinder. Each of the first and second partial cylinders is provided with its own dedicated drive motor to accomplish the rotational movement of each partial cylinder.

A cylinder of a rotary printing machine has cylinder parts that can be driven and rotated independently of one another. The cylinder parts each have a drive connection to an electric motor and can be driven independently of one another.

The method includes rotating a drum about an axis of rotation. A discrete length of elastic substrate is positioned on the outer circumferential surface of the rotating drum, wherein the discrete length of elastic substrate is in a stretched state and defines a first length. The discrete length of elastic substrate may be defined by a first end region, a second end region, and a central region separating the first and second end regions. The method may comprise applying vacuum pressure to the first, second, and central regions of the discrete length of elastic substrate. Vacuum pressure may be reduced on the first and second end regions such that the discrete length of elastic substrate consolidates to a second length that is less than the first length.

A machine for processing printing material sheets, in particular a sheet-fed printing press, has a sheet transport drum for transporting the printing material sheets and at least one sheet supporting element. The sheet supporting element, which is formed with a sheet supporting surface, is compatible with the sheet transport drum, for supporting the printing material sheets in a first operating mode. When the machine is operated in the first operating mode the sheet supporting element is held attached to the sheet transport drum, and when the machine is operated in a second operating mode the sheet supporting element is stored in the machine detached from the sheet transport drum. A corresponding printing material processing machine is suitable for carrying out the novel method.

A folding cylinder includes a frame having a work-side support and a gear-side support, at least one expansion segment for providing an effective diameter of the cylinder, the expansion segment being located between the work-side support and the gear-side support and spaced apart from at least one of the work-side support and the gear-side support, and an actuating device for contacting the at least one expansion segment and setting the effective diameter.
