Definitions

  • the invention relates to a web-fed rotary printing press according to the preamble of claim 1.
  • a web-fed rotary press has several printing units for printing at least one printing material web.
  • several printing units in the form of printing towers are usually positioned vertically one above the other.
  • the web-fed rotary printing press has a folding apparatus, wherein in the area of the folder of the or each printing material copies are separated by transverse cutting.
  • the folder is used to form at least one transverse fold and / or at least one longitudinal fold on the separated copies.
  • a so-called reversing and folding structure is positioned, wherein at least one printing material web can be separated into partial webs by longitudinal cutting in the region of the turning and folding structure.
  • the or each printing material web or the or each partial web can be fed via turning bars and / or guide rolls to at least one former of the turning and folding structure.
  • the present invention is based on the problem to provide a novel web-fed rotary printing press.
  • This problem is solved by a web-fed rotary printing press according to claim 1.
  • at least one guide roller is positioned along the transport path of the or each printing material web and / or the or each partial web by the turning and folding structure, whose both ends are each assigned an adjusting unit via which the respective end of the respective guide roll in and / or opposite is linearly displaceable to the direction of the respective substrate web or sub-web, namely such that either both ends of the respective guide roller uniformly to influence the cut register or both ends of the respective guide roll non-uniformly to influence the edge position of the respective printing substrate or partial web are displaced.
  • the control of the cut register and the regulation of the web edge position of the or each printing material or the or each sub-web is realized in common by at least one guide roller.
  • Section control and web edge control are therefore not realized in the printing machine according to the invention by separate units, but rather combined in one unit. As a result, space can be saved.
  • Each adjustment unit is preferably designed as an electromotive actuator, in particular as an electromotive linear drive.
  • the present invention relates to a web-fed rotary printing press having a plurality of printing units for printing at least one printing material web and a folding apparatus.
  • copies can be separated by cross cutting from the or each printing material web.
  • at least one longitudinal fold and / or at least one transverse fold can be formed in the area of the folding apparatus.
  • a so-called turning and folding structure is positioned between the printing units and the folder.
  • Fig. 1 shows a section of a web-fed rotary printing press in the region of a turning structure 10, wherein in the region of the turning structure 10 of the Fig. 1 a printed substrate web 11 by means of a cutting device 12 by longitudinal cutting into two partial webs 13, 14 is separated.
  • the partial webs 13, 14 are fed via guide rollers 15, 16 a former 17 of the folding structure 10 downstream of the folding structure 18.
  • longitudinal folds are formed on the partial webs 13, 14 seen in the transport direction of the partial webs 13, 14, downstream of the former 17 are separated by cross cutting of the partial webs 13, 14 and thus of the printing substrate 11 copies.
  • At least one guide roller 15 is positioned along the transport path of the two partial webs 13, 14, whose two ends 19, 20 each have an adjusting unit 21 (see FIG Fig. 2 ) is assigned, via which the respective end 19, 20 of the respective guide roller 15 in or opposite to the direction of the respective partial web 13, 14 is linearly displaceable.
  • the linear displaceability of the ends 19, 20 of the guide rollers 15 is in Fig. 1 . 2 visualized by arrows 22.
  • each guide roller 15 the ends 19, 20 via the corresponding adjusting units 21 either uniformly for influencing or regulating the cut register or non-uniform for influencing or regulating the edge position of the respective partial web 13, 14 displaced.
  • guide roller 15 therefore serves on the one hand the web edge control and on the other hand, the cut register control.
  • the adjusting unit 21 associated with each guide roller 15 are either uniformly or non-uniformly controlled to linearly shift the respective ends 19, 20 of the respective guide roller 15 either uniformly or non-uniformly in the direction or opposite to the direction of the respective partial web 13, 14.
  • Each adjustment unit 21 is preferably designed as an electromotive actuator, in particular as an electromotive linear drive. This allows a shift of the guide rollers 15 with a high dynamic, so that a simultaneous, dynamic control of cutting register and lateral edge position of the respective sub-web or substrate web is possible.
  • Fig. 1 shows a possible embodiment of a turning structure 10, which is associated with at least one adjusting unit 15 for each partial web 13, 14.
  • the invention is not limited to this specific application. Rather, the invention can also be used in web-fed rotary printing presses with other turning assemblies and folder superstructures.
