Abstract

The invention relates to a plate cylinder, said plate cylinder having a channel in which a tensioning device is arranged. The tensioning device has a front and a rear clamping device, and the rear clamping device is part of a slide of the tensioning device. The slide is arranged so as to be movable along a tensioning path in a tensioning direction towards the front clamping device within the channel by means of a tensioning drive, and a maximum displacement of the slide in and / or opposite the tensioning direction relative to a plate cylinder body is at least as large as an extension of a provided contact surface between a printing plate that is clamped in the rear clamping device and a radially outer clamping element of the rear clamping device, said extension being measured in the tensioning direction.; The invention also relates to a method for arranging a printing plate onto a plate cylinder.

Description

technical field

[0001] The invention relates to a printing plate cylinder according to the preamble of claim 1 and a method for arranging printing plates on a printing plate cylinder according to the features of claim 22 . Background technique

[0002] In printing presses, forme cylinders are frequently used which are designed as plate cylinders and which carry printing formes in the form of printing plates. These printing plates can be replaced. For this purpose, a device is required which detachably fixes the printing plate on the plate cylinder. As the demands placed on the accuracy of the printed products produced by the printing press are increasing, so are the demands placed on the accuracy of the arrangement of the printing plates on the plate cylinder. In currency printing, for example, at least the accuracy of the position of the printing plates relative to each other is required to be in the micrometer range. This level of precision cannot be achieved with the p...
