Embodiment Construction

[0030] figure 1 A first embodiment of the gravure printing unit 10 according to the invention is shown schematically in a printing press 12 , in particular in a combined or hybrid printing press. An embodiment of the gravure printing unit 10 has a printing cylinder 14 (gravure printing cylinder) which cooperates with an impression cylinder 16 to form a printing nip and against which an inking unit 18 rests. The path of a web of printing material 34 extends across the printing nip. When the intaglio printing unit 10 is in operation, the impression cylinder 16 rotates in the direction of rotation 20 and the printing cylinder 14 rotates in the direction of rotation 22 , while the printing web moves along its path in the direction of transport 24 . In this embodiment, the axes of rotation of the two rollers lie in a substantially horizontal plane. The inking device 18 is designed as an ink fountain scraper 26, which is filled with gravure ink 28 and is arranged on the left secti...

Abstract

The invention relates to a printing machine (12), in particular to a recess printing device (10) which is used to print drum printing material (34) in a label-printing machine, and the invention comprises at least a printing drum (14), an inking device (18) and an impression cylinder (16), wherein the recess printing device (10) is provided with at least a connecting component (36,48,50) which is used to be detachably received on at least a connecting platform (38,52,54) of the printing machine (12), and is used to connect with a detachable function of a single driving device (68) which is used on the printing drum (14), and thus, the printing drum (14) and the inking device (18) can be separated with at least a connecting platform (38,52,54), wherein the impression cylinder (16) is still kept in the printing machine (12).

Description

technical field [0001] The invention relates to an intaglio printing unit for printing webs in a printing press, which has at least one printing cylinder, an inking unit and an impression cylinder. technical background [0002] There is an ever-increasing demand for greater flexibility or variability in printing machines for printing labels, especially self-adhesive labels, in order to realize as many different types of finishing tasks as possible, especially with printed images or printed text Print finishing tasks that produce specialized optical effects. For the production of labels, in particular printing presses are often used which process narrow webs of printing material and which have a plurality of connection platforms or interfaces, each of which detachably receives a label for printing with a defined printing method. A functional unit or method component. An embodiment of such a printing machine is described, for example, in document US Pat. No. 4,384,522. The ...
