Embodiment Construction

[0022] The present invention will be described below with reference to FIGS. 1 to 5 .

[0023] FIG. 1 shows a schematic end view of a converter sleeve 4 with a fitted circulation sleeve 1 . The converter sleeve 4 is fitted with an inner diameter of 4.3 onto the cylinder core of the new plate cylinder. The printing format can be adjusted by adjusting the outer diameter 4.4 of the converter sleeve 4 . Both the inner diameter 4.3 and the outer diameter 4.4 of the converter sleeve 4 can be adapted to the cylinder core and the printing format.

[0024] FIG. 2 shows the converter sleeve 4 from FIG. 1 , in which the welded sleeve 2 is fitted. In the upper part of the converter sleeve, the welding seam 2.1 of the sleeve is indicated by a dot.

[0025] Figure 3 shows a cross-sectional view of the structure of the plate cylinder along the longitudinal axis of the cylinder. The plate cylinder 3 , which rotates about an axis of rotation 3 . 2 , is mounted on both sides in the printing...

Abstract

A printing cylinder for a rotary web press to which at least one printing form is attached and a method for operating a rotary web press is disclosed. The printing cylinder is built up of at least one cylinder core and an adapter sleeve installed thereon, wherein the adapter sleeve is configured in such a way that either printing forms in the shape of sleeves or printing plates can be attached thereto before the printing process, depending on the size of the print run.

Description

technical field [0001] The invention relates to a printing plate cylinder of a web printing press, to which at least one printing plate is mounted. Furthermore, the invention relates to a method for driving a web printing press. Background technique [0002] In the known printing presses, forme cylinders or platen cylinders with clamping systems are used in the printing units in order to clamp the respective printing formes on the forme cylinders or platen cylinders. Most of the printing plates are disposable platens, which are usually produced off-line in plate-setting machines. Printed images are usually imprinted on such disposable press plates, which usually support a high printing force. After printing, the disposable platen is discarded. [0003] In the field of digital printing, for example, the applicant's DICOWEB system has disclosed a plate cylinder or a platen cylinder used in a printing device, which uses a sleeve (ie, a sleeve-shaped platen) instead of a plat...
