Problems solved by technology

This can lead to the fact that the downstream pre-registration is started before a stable state of the upstream printing unit has been reached, for example due to erroneous readings or due to haste, and must therefore be restarted.

Embodiment Construction

[0035] exist figure 1 A processing machine is shown in FIG. 2 , which is designed as a printing press and is suitable for carrying out the method according to the invention for automatic presetting or resetting of the register state. The printing press is indicated generally at 100 .

[0036] In the schematic illustration, the printing press 100 has four clamping points, here configured as printing units. It goes without saying, however, that a larger or smaller number of printing units can also be provided without departing from the invention. The printing unit 10 accordingly has a printing cylinder 11 . The printing cylinders 11 are each provided with a drive, preferably a single drive (so-called “shaftless drive technology”), but these are not shown in the figures. The printing press 100 is designed to process a material web 1 , here a paper web.

[0037] Furthermore, each printing unit 10 has a pressure roller 12 with which the paper web 1 can be pressed against the pr...

Abstract

The present invention relates to an automatic axis correction method for use in a treatment machine for treating a material web (1), especially in a shaftless printing press (100), the material web (1) being subdividable into at least two web tension sections, a web tension section being delimited by two clamping positions (10, 50, 60) that are designed as transport or treatment devices (10). According to said method, an axis deviation from at least one clamping position (10, 50, 60) which is designed as a treatment device (10) is determined, the at least one clamping position (10, 50, 60) is then released, the axis position is automatically corrected based on the axis deviation determined earlier and the clamping point is closed after axis correction.

Description

technical field [0001] The invention relates to a method for automatic axis alignment on a processing machine for processing a material web, a corresponding computer program and a corresponding computer program product. [0002] Although the following mainly refers to printing machines, the invention is not restricted thereto, but rather relates to all types of processing machines for processing material webs or material webs. However, the invention can be used in particular on printing presses such as newspaper printing presses, odd-print printing presses, gravure printing presses, packaging printing presses or security printing presses and on processing machines such as bag-making machines, envelope-making machines, packaging on board. The web may consist of paper, fabric, cardboard, plastic, metal, rubber in film form or the like. Background technique [0003] For the relevant processing machines, especially printing presses, the web is driven along a driven axis (web t...
