DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a cylinder for a rotary printing press, a method for dividing a cylinder and a method for producing a cylinder.
DESCRIPTION OF THE INVENTION
DE-PS 875 205 describes a cylinder with several individual sleeve-like cylinders arranged on a common shaft.
It is disadvantageous in connection with this cylinder that the individual cylinders cannot form an uninterrupted surface.
DE 27 45 086 A1 describes an ink duct cylinder for containing different inks in adjacent areas, whose barrels have circulating separating grooves. These separating grooves can be filled with a flexible tape.
SUMMARY OF THE INVENTION
It is the object of the invention to create a cylinder.
The advantages which can be attained by means of the invention reside in particular in that a barrel of a cylinder can be selectively divided into sections. In this way it is possible, for example, to adapt the cylinder to a plurality of plates placed at a distance next to each other, without it being necessary to change cylinders. Accumulations of ink in the area of the spaces between the plates are prevented. Printing disruptions are reduced by this and the print quality is increased.
If the division is obtained by means of a constriction of a continuous surface area, the latter sealingly covers the operating means for creating this constriction, so that no ink, for example, can penetrate into the interior of the cylinder.
The cylinders can be remotely controlled, i.e. they can also be adjusted while the press is running, for example.
The cylinder in accordance with the invention for a rotary printing press is represented in the drawings and will be described in greater detail in what follows.

DESCRIPTION OF THE PREFERRED EMBODIMENT
A cylinder 1 essentially has two journals 3, 4 and a barrel 6. The journals 3, 4 are stationary fastened, for example in relation to lateral frames, not represented, and the barrel 6 is rotatably seated on the journals 3, 4. In the present exemplary embodiments, a surface area 8 of the barrel 6 is provided with a circulating groove 11 in its center, so that the cylinder 1 is designed approximately axis-symmetrically in respect to a center line 12 of this groove 11. This cylinder 1 preferably is an ink or moistur
