Problems solved by technology

Common narrow-belt printing presses designed for label printing, especially for self-adhesive labels, in a tandem structure generally have a machine structure in which the printing material or substrate is passed through several cylinders or rollers on different between process planes (eg for printing and for drying), whereby very long belt sections are stored in the printing press and corresponding waste pages may be produced

Embodiment Construction

[0038] figure 1 shows a view of a preferred embodiment of a printing machine 42 according to the invention, more precisely a label printing machine according to the invention, in the form of a tandem structure with several horizontally consecutive printing machines according to the invention The printing device 10. The label printing machine is used for processing web-shaped printing materials 44 . The substrate is unwound from a substrate roll 46 in an input section 48 of the printing press 42 and is guided through the printing press 42 along a path. The printing press 42 has a plurality of frame modules 26 , here by way of example three frame modules 26 . In this embodiment, two printing units 10 or a printing unit 10 and a processing unit 50, here a stamping unit (Stanzwerk) for stamping labels on a web-shaped printing material 44, are accommodated in each case. on a rack module 26. Following the individual processing stations is an output section 52 in which the manufa...

Abstract

The invention relates to a printing unit (10) of compact construction and includes an impression cylinder (14) and a printing form cylinder (12) to be pivoted around the impression cylinder (14) about a pivot axis running parallel to an axis of rotation of the impression cylinder (14). A spacing between the axes of rotation of the printing form cylinder (12) and of the impression cylinder (14) can be varied and the printing form cylinder (14) and the impression cylinder (14) can be set against each other, to form a press nip in which a substrate (44) can be printed. A first drive (38) for producing a rotational movement of the printing form cylinder (12) is connected to the printing form cylinder (12) through a drive train (64). At least one component of the drive train (64) has a torque axis running through the impression cylinder (14). A printing press (42) according to the invention comprises at least one printing unit (10).

Description

technical field [0001] The invention relates to a printing unit having an impression cylinder and a plate cylinder, which is pivotable around the impression cylinder about a pivot axis extending parallel to the axis of rotation of the impression cylinder , wherein the distance between the axis of rotation of the printing plate cylinder and the axis of rotation of the impression cylinder can be varied and the plate cylinder and the impression cylinder can be pressed against each other, thus forming a printing gap, and the substrate can be printed on the To be printed in the gap, the printing unit also has a stationary first drive device for generating a rotational movement of the printing plate cylinder. Furthermore, the invention relates to a printing press with such a printing unit. Background technique [0002] Increasingly, particularly high demands are placed on printing machines designed or used for label printing or packaging printing in terms of economy and ease of o...
