Definitions

  • the invention relates to a pair of rollers according to the preamble of claim 1 as well as a material web processing machine according to the preamble of Claim 12.
  • Material web processing machines for example, are from the prior art Web-fed rotary printing machines, known in which one web of material has several Machine units of the material processing machine is guided and doing so different processing processes, for example printing, drying, cooling or Folding, is subjected.
  • the material web to be processed which for example a Paper web, textile or plastic web can be done via management units such as for example rotating rollers or non-rotating guide bars or turning bars performed, a change of direction or a turning of the material web also being carried out can be.
  • DE 31 28 430 C2 describes a rotary printing press with a dryer subsequent cooling plant known, which consists of several, in the direction of web travel successively arranged machine units.
  • the web of material passes through a reel changer, a voltage regulator, several printing units, a web catching device, a dryer, a cooling roll stand and a folder.
  • the individual machine units of the rotary printing press, in particular the dryer and the chill roll stand are spaced apart from each other arranged and the material web is from a first machine unit to a second Machine unit moved on without intermediate web guiding elements.
  • Such rotary printing machines basically have the need to To keep the tension of the material web in a fixed predetermined value range, so that optimal printing and folding results can be generated and in particular a web break can be avoided.
  • Unfavorable changes in web tension can occur in one such a rotary printing press, for example, arise from the fact that a Machine unit of the web-fed rotary printing press, in which the material web over Web guiding elements is guided due to temperature fluctuations expands or deforms. As a result, this leads to an adverse movement of the Machine unit together with the web guiding elements, so that the distance between the individual machine units and thus the length of the path varies a change in web tension at least in the web section between two Machine units is caused. A deformation of the machine unit leads to Furthermore, an uneven distribution of the web tension over the width of the Web, so that it is in the web section for wrinkling, in particular longitudinal and Diagonal folds and a web offset occurs.
  • EP 0 627 311 B1 shows a web cooling device which is a hot air dryer is directly subordinate in the direction of web travel, in such a way that the housing of the Web cooling device directly adjacent to the dryer housing. It is from the State of the art also known that hot air dryers a combustion chamber Heating the gas in the dryer have, which during operation generate temperatures in the range of 200 to 300 ° C in the dryer. By the temperature prevailing in the dryer becomes beyond the intended heating the web of material also heats the dryer housing, which is thereby at a Length of the dryer from about 10 to 15 m can extend by several centimeters.
  • This Expansion of the housing results in movement, or in the event of an uneven movement Heat distribution in the dryer to deform the dryer, this Movement to the web cooling device directly downstream of the dryer and the chill rolls received therein is transmitted.

  • Another embodiment of the invention can be characterized in that the first roller is arranged in the first machine unit such that the material web in a direction to the first roller is fed, which is substantially perpendicular to a direction of the first machine unit in which a movement or Deformation of the machine unit takes place.
  • a substantially vertical feed of the Material web to the first roller advantageously leads to the fact that the through a Compensating movement of the first roller caused change in the length of the Path paths in the feed section to the first roller is kept as low as possible.
  • the first roller in the first machine unit to arrange that the material web the first roller with a wrap angle of essentially wraps around 90 °.
  • This advantageous arrangement of the first roller leads also means that the direction of movement of the first machine unit and the Feed direction of the material web to the first roller essentially perpendicular to one another stand so that the amount of displacement of the first machine unit does not become one same amount of change in length of the path leads.
