Embodiment Construction

[0026] FIG. 1 shows a printing unit 10 according to the invention, which is embodied as a flexographic printing unit. The printing unit 10 has a printing form cylinder 2 , an anilox roller 1 and a counterpressure cylinder 3 . A doctor blade 5 is installed on the anilox roll 1 . The anilox roller 1 and the printing plate cylinder 2 have a bearing 6.1 which is arranged on a common bearing plate 6.2. Mounted on the bearing 6 . 1 of the printing plate cylinder 2 is a toggle linkage system 4 . 1 which exerts a prestressing force F on the bearing 6 . 1 and thus onto the printing cylinder 2 . The carrier plate 6.2 is assigned a servo drive 7, wherein the movement of the servo drive 7 is transmitted via the spindle 9 to the carrier plate 6.2. It is thereby possible to slide the position of the bearing plate 6 . Figure 1a A plate cylinder 2 of larger diameter is shown in , while Figure 1b A plate cylinder 2 of smaller diameter is shown. In order to form a further printing gap bet...

Abstract

The invention relates to a printing unit (10) with an anilox roller (1), a plate cylinder (2) and a counter-pressure cylinder (3), wherein the rotation of the anilox roller (1) and the plate cylinder (2) The axes are arranged in a horizontal plane (HE) and the axes of rotation of the plate cylinder (2) and counterpressure cylinder (3) are arranged in a vertical plane (VE). The printing unit (10) has at least one toggle system (4.1) for applying a preload (F) to the plate cylinder (2).

Description

technical field [0001] The invention relates to a printing unit having the features of the preamble of claim 1 and to a narrow-web label printing machine having the features of claim 10 . Background technique [0002] There is an increasing need for greater flexibility or variability in printing machines for printing labels and folding boxes in order to be able to perform as many different types of printing tasks as possible, especially by printing images or printing text to create special visual effects . For the production of labels and folding boxes in particular printing machines are often used which process narrow strips of printing material and which have a number of connecting platforms or interfaces on which correspondingly detachable receiving functional A unit or method module for printing with a specific printing method. An embodiment of such a printing machine is described, for example, in document US Pat. No. 4,384,522. In this case, individual functional uni...
