Examples include a die-cutting unit that includes a device for changing a die-cutting cylinder. The die-cutting unit includes at least one die-cutting cylinder and at least one anvil cylinder. The die-cutting cylinder is arranged in a die-cutting position for die-cutting, and the at least one die-cutting cylinder is exchangeable for at least one other die-cutting cylinder by means of the device for changing the die-cutting cylinder. A shortest straight connecting line between the axis of rotation of the die-cutting cylinder in the die-cutting position and the axis of rotation of the die-cutting cylinder in the move-out position is inclined less than 30 degrees with respect to a horizontal plane. Further, a shortest straight connecting line between the axis of rotation of the die-cutting cylinder in the move-out position and a maintenance position is inclined less than 30 degrees with respect to a vertical direction.

Die-cutting unit comprising a device for changing a die-cutting cylinder and method for changing a die-cutting cylinder

A transport device for a sheet-format substrate has at least one first substrate feed device and has at least one second substrate feed device. The at least one second substrate feed device comprises at least one forward stop and at least one singulating device. At least one substrate guiding device is arranged between the at least one first substrate feed device and the at least one second substrate feed device. The at least one substrate guiding device has at least one directing element. The at least one directing element is mounted such that it is movable or is moved in two different directions independently of one another.

Transport devices for a sheet-format substrate and method for transporting at least one sheet-format substrate

A substrate-feeding device has at least two acceleration devices, which are arranged one beside the other, beneath a storage region, and having a framework and a lifting frame, which lifting frame can be moved relative to the framework. The at least two acceleration devices are arranged for movement jointly with one another, and with the lifting frame. Each of the acceleration devices has at least one body of rotation, which is driven via a common shaft which has at least two shaft portions arranged one behind the other. Directly adjacent shaft portions are arranged in a state in which they are connected in each case, via a coupling. There are subassemblies provided which each have a deflecting device, a shaft portion and at least one transporting belt and which are each one of fastened on the lifting frame, and are arranged for movement jointly with the lifting frame and are connected to one another by virtue of their shaft portions being connected via couplings to form the common shaft. The invention also relates to a sheet-processing machine.
