Embodiment Construction

[0043] A comprehensive description is given below Figures 1 to 5 , where the same elements are denoted by the same reference numerals.

[0044] exist figure 1 In , the processing machine designed as a printing press is denoted by 100 as a whole. Printing material (such as paper 101 ) is transported into the machine through an infeed mechanism (Infeed) 110 . The paper 101 is conveyed and printed through the nip positions configured as printing mechanisms 111 , 112 , 113 , and 114 , and is sent out again by an outfeed mechanism (Outfeed) 115 . These paper feeding mechanism, paper discharging mechanism and printing mechanism 110 to 115 are arranged to be able to position, especially can correct cylinder or angle. The printing units 111 to 114 are located in the area between the paper feeding unit 110 and the paper delivery unit 115 for adjusting the web tension.

[0045] The printing units 111 to 114 respectively have printing cylinders 111' to 114', and the pressure cylinde...

Abstract

The method involves dividing a material web (101) into two web tension sections, where each web tension section is limited by clamping points (111-114) e.g. printing elements. A web tension adjusting unit (115) and the clamping points are exhibited. The web tension adjusting unit is impinged during clamping of the material web by closing the clamping points, where the tension adjusting unit has pilot control variable including an angle value, a velocity value and / or a drive moment. Independent claims are also included for the following: (1) a web tension adjusting processing unit (2) a computer program comprising an instructions for executing a web tension adjusting method. Web tension adjusting method for processing machine e.g. shaftless printing machine, involves exhibiting web tension adjusting unit and clamping points, where adjusting unit is impinged during clamping of material web by closing points.

Description

technical field [0001] The invention relates to a method for adjusting the web tension in a processing machine, as well as to a computing unit, a corresponding computer program and a corresponding computer program product. [0002] Although reference is mainly made below to printing machines, the invention is not restricted thereto but relates to all types of processing machines for processing material webs or material webs. However, the invention can be used in particular in printing presses, such as newspaper printing presses, odd printing presses, gravure printing presses, packaging printing presses or securities printing presses, or in processing machines, such as bag making machines, envelope machines or packaging machine. The material web can be composed of film-like paper, cloth, cardboard, plastic, metal, rubber, etc. Background technique [0003] In processing machines, especially in printing presses, the web travels along drive shafts (web transport axes such as ...
