Definitions

  • the invention relates to a former for a folder of a rotary printing press according to the preamble of claim 1.
  • a former for a folder of a web-fed rotary printing press is known, which is arranged in side frames above a folding cylinder group with horizontal cylinder axes.
  • the invention has for its object to provide a former, which makes it possible to easily expand the imposition scheme.
  • the web-fed rotary printing press can be used both for the production of newspapers (with the puncture on the newspaper foot) and for commercial prints. Complicated turning devices are not required. With four-color printing, it is no longer necessary for the paper web side printed in four colors to run over paper guide rollers. Four-color printing can be easily placed either on the outside of the folded product or inwards.
  • the paper web 1 is e.g. monochrome, the paper web 2 printed in four colors in face and reverse printing and then fed through a drying oven 9 via paper guide rollers 11 to a folding former 12 according to the invention in a folding unit 13.
  • the folding former 12 is mounted in side frames 14, 16 in a known manner.
  • paper guide rollers 17 and driven draw rollers 18, 19 are also arranged in a known manner.
  • the side frames 14, 16 are screwed to a carousel upper part 21.
  • the upper part of the carousel 21 is seated on a carousel base 22.
  • the upper part of the carousel 21 can be rotated on the base of the carousel 22 by means of a steering ring 23.
  • the carousel upper part 21 and a lower ring 26 of the steering ring 23 are attached to the carousel base 22 on an upper ring 24 of the steering ring 23.
  • the folding former 12 attached to the side frames 14, 16 can thus be rotated horizontally by at least 180 °.
  • the side frames 14, 16 are fastened to the upper ring 24 via four horizontal upper struts 27, 28, 29, 31.
  • Locking devices 39, 41 ensure that the former 12 can be held either in the “0 ° position” or in the “180 ° position”.
  • a locking stop 42, 43 in the form of a tab is attached to the carousel base 22 and an upper locking part 44, 46 in the form of a tab is attached to the top of the carousel 21.
  • the upper locking parts 44 and 46 strike in the locking positions 0 ° and 180 ° on the locking stops 42 and 43.
  • In each of the upper locking parts 44, 46 there is a hole through which a screw is screwed into the threaded hole, so that the upper part of the carousel 21 is securely locked on the base 22 of the carousel.
  • two vertical fastening plates 40, 45 are attached, between which two conventional funnel inlet rollers 47, 48 are rotatably mounted in their lower ends.
