Definitions

  • the present invention relates to a folder assembly and method for folding a plurality of printed web cords in a web-fed rotary newspaper press according to the preamble of claims 1 and 10.
  • the stacked and longitudinally folded web strands After leaving the former section, the stacked and longitudinally folded web strands once more superimposed and a Subordinated folder supplied in which they folded horizontally, in individual signatures be cut and then transported to a mailroom in which the finished newspapers are collected, stacked and made ready for despatch.
  • former sections typically comprise three Folding funnel pairs of stacking formers and a fixed in the Printing arranged folding machine, the superimposed and longitudinally folded Web strands are supplied.
  • the supply of folded, superimposed Web cords to the folder by means of a variety of each below the Forming rollers arranged guide rollers around which the longitudinally folded, one above the other lying web strands are performed.
  • the prior art document DE-A-2846191 discloses a folder for Web-fed rotary printing presses, wherein above the fixed folder two rows of each four folders are provided. About each former is a single guided longitudinally stranded, longitudinally folded and at a single point by means of two rolls merged paper strand bundles in the vertical direction of the Einlaufzwickel fed to two cross-cutting rollers of the folder.
  • DE-A-25 10 057 also describes a folding method and a folder for the Newspaper production whereby paper webs in printing units are printed on both sides and individually, d. h not merged, a former arrangement of upper and lower Falztrichtem and merged a single, including fixedly arranged Folder be fed with folding cylinder.
  • the upper formers are inclined to one side down, while the lower formers are tilted down to the other side, i. opposite are aligned so that the merged before the folder webs respectively have an opposite orientation. This causes the folded edges the various sections on opposite sides of the finished product whereby the product has a uniform overall thickness.
  • From DE-C-554 955 is also a folding unit for rotary printing machines known, with a double-width, printed paper web cut several times and led to the generation of two strands via two juxtaposed former becomes.
  • a first operating configuration become the two strands of a respective folding and cutting device supplied, which with respect to their inlet gusset between folding and Cutting cylinder is located vertically below the respective folder tip while in one second operating configuration, the two generated strands of a common, centered arranged folding and cutting device are supplied.
