Problems solved by technology

[0010] The disadvantage of this solution according to the prior art is that, on the one hand, input errors can occur when the data are predetermined by the user and, on the other hand, the necessary data, such as the modulus of elasticity in particular, are not always known exactly.

Embodiment Construction

[0036] FIG. 1 shows a preferred embodiment of a processing machine according to the invention, which is designed as a printing press and is generally designated 100 . Printed material such as paper 101 is fed to the machine by a pull-in unit 110 . The sheet 101 is guided and printed on by means of clamping stations designed as printing units 111 , 112 , 113 , 114 and is conveyed out again by means of a withdrawal unit 115 . The infeed, outfeed and printing units 110 to 115 are arranged in such a way that they can be positioned, in particular cylinder alignment or angle alignment is possible. The printing units 111 to 114 are located in the region of the web tension adjustment between the infeed unit 110 and the outfeed unit 115 .

[0037] The printing units 111 to 114 have printing cylinders 111' to 114', respectively, against which press rollers 111" to 114" bear with strong pressure, respectively. The printing cylinders 111' to 114' can here be driven individually and inde...

Abstract

The present invention relates to a method of an axle correction of a processing machine and a processing machine, the processing machine includes, for conveying and processing a continuous material (101), at least two driven conveyance axles (110, 115), at least one non-driven or driven processing axle (111, 112, 113, 114), and at least one further non-driven axle (102, 121, 122, 123, 124), wherein an elasticity module of a material (101) is determined, while a rotational speed of the clamping point which limits a web-tension section is being changed, a precontrol of this clamping point which limits the web-tension section, and / or a processing axle (111-114) which is present in this web-tension section is carried out with consideration of the elasticity module of the material which comprises the continuous material and with consideration for a rotational inertia of at least one non-driven axle (102, 121-124) which is present in this web-tension section.

Description

technical field [0001] The invention relates to a method for axis alignment on a processing machine, as well as to a corresponding processing machine, 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 object 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, in-line flexographic printing presses, packaging printing presses or security printing presses. The article web can consist of paper, cloth, cardboard, plastic, metal, rubber in the form of a film or the like. Background technique [0003] On processing machines, especially printing presses, the product web moves along driven axes (web transport axes) such as pinch rollers or feed rollers and...
