Embodiment Construction

[0025] exist Figure 1 to Figure 9 In , elements and components corresponding to each other are denoted by the same reference numerals.

[0026] exist Figures 1 to 9 A printing press 41 for lithographic offset printing on sheets is shown in a partial view. The corresponding detail shows the anilox printing unit 2 of the printing press 1 . In all exemplary embodiments, the anilox printing unit 2 comprises a printing form cylinder 3 with a first pillow 4 and a zone-free or keyless (English: keyless) inking unit 5 . The blanket cylinder and impression cylinder of the anilox printing device 2 are not shown in the figure. The inking unit 5 comprises an anilox roller (Anilox roller) 6 with a second pillow 7 and an ink application roller 8 with a third pillow 9 . The ink application roller 8 is mounted on the operating side of the printing press 1 in a bearing device and on the drive side in such a further bearing device 10 . Only the drive-side bearing device 10 is shown in th...

Abstract

The invention relates to an anilox roll printing apparatus (2), comprising a plate cylinder (3) with a first cylinder bearer (4), an anilox roll (6) with a second cylinder bearer (7) and an ink applying roller (8) supported in a supporting device (10). The supporting device is loaded by a spring (28); the spring presses a third cylinder bearer (9) onto the second cylinder bearer (7); and the spring (28) presses the third cylinder bearer (9) onto the first cylinder bearer (4) simultaneously.

Description

technical field [0001] The invention relates to an anilox printing unit according to the preamble of claim 1, comprising a printing plate cylinder with a first pillow, an anilox roller with a second pillow and a printing cylinder with a third roller. An ink applicator roller of the roller, wherein the ink applicator roller is supported in a support device loaded by a spring which presses the third roller pillow against the second roller pillow during printing operation. Background technique [0002] One such anilox printing unit is described in DE 10 2007 052 ​​761 A1. In this prior art printing unit, springs keep the compression between the bolsters of the anilox roller and the bolsters of the ink applicator roller substantially constant. This is important, for example, when changing anilox rolls which, within the scope of manufacturing tolerances, have different pillow diameters from one anilox roll to another. However, no attention is paid here to the compression betwee...
