Embodiment Construction

[0032]Figure 1 to 7 The preferred embodiment of the present invention in accordance with the preferred embodiment of the present invention is illustrated in a schematic side view.

[0033]infigure 1 The printing press of the printing machine 1, in particular processing page is shown, which has an automated plate transform device 2 and a roller 3, in particular imprinting plate (or plate drum). The plate transform device has a swingable first guide 2a and a swingable second guide 2b for the plate to be converted, and a roller having not shown. The drum 3 and the plate transform device 2 are supported (or fixed) in a side wall not shown in the printing press 1. In order to perform an automated plate transformation, a control device that is also not shown is provided. The control device controls the rotational motion of the drum, the swing moving movement of the guide, and the translation of the plate to be shifted, and the translational movement of the plate to be transformed.

Abstract

The invention relates to a method for changing printing plates on a cylinder, comprising the following rotation step: a first rotation of the cylinder (3) in a first direction (7), wherein the first printing plate (5) is moved by the cylinder Disassembly of the circumferential surface (4) of (3); second rotation of the cylinder (3) in the opposite second direction (8), wherein a second printing plate (6) replacing the first printing plate (5) is assembled on the circumferential surface (4) of the cylinder (3); and includes the following opening steps: opening the first clamping device (9) and releasing the front edge (5a) of the first printing plate (5); opening the second clamping tightening device (10) and release the trailing edge (5b) of the first printing plate (5); characterized in that both the first clamping device (9) and the second clamping device (10) are on the cylinder (3) opens before the first spin. The invention advantageously enables the reduction of retooling times for changing printing plates. The invention also relates to a device for carrying out the method.

Description

Technical field[0001]The present invention relates to a method for transforming a plate on a roller, and further relates to an apparatus for performing the method described.[0002]The present invention is based on the technical field of graphics industries, in particular, based on the field of IndiRekten FlachDRUCK, known as offset printing, is related to the flat substrate, and is also applying to the printing ink and / or brilli. In the form of the form or the forming material, the receiving material is preferably made of paper, thick paper, cardboard or plastic; in particular, the invention, in particular, based on the field of DRUCKPLATENWECHSEL.Background technique[0003]In the automated task transformation in offset printing, the printing plate is converted, ie the printing plate is disassembled from the plate drum, and the new printing of the subsequent task is mounted on the plate drum. Here, the clamping device of the plate drum (these clamping means holds these clamping plat...
