Definitions

  • the invention relates to a device for transverse perforation according to the preamble of one of claims 1 to 3.
  • the correction of the transverse perforation associated with the first transverse fold is carried out by correspondingly rotating a pair of perforating cylinders equipped with perforating knives and strips relative to the pair of folding cylinders comprising a folding knife and a folding jaw cylinder.
  • the adjustment can be made while the machine is running, for example with the aid of an oppositely helical toothed double block gear block inserted into the gear drive between the two devices.
  • the setting of the transverse perforations assigned to the second transverse fold performed by a further folding cylinder group is carried out when the machine is at a standstill by individually adjusting the relevant perforating knives and perforating strips with, for example, adjusting screws which engage their holders and are otherwise connected to the perforating cylinder body.
  • the invention has for its object to provide a device for transverse perforation according to the preamble of one of claims 1 to 3, which enables the cross-perforations associated with the cross-folds to be adjusted while the machine is running, which meets the requirements of the first and second transverse folds.
  • FIG. 1 shows a folder of a rotary printing press with a web 2 running in via a former 1 which executes the first longitudinal fold. Subsequently, between two pairs of drawing rollers 3; 4 one of two perforating cylinders 5; 6 existing device for transverse perforation of the web 2 is arranged, which is cut between a knife cylinder 7 and a folding knife cylinder 8 equipped with cutting bars into sheets held on the latter by means of punctures.
  • the sheets then receive the first transverse fold in a transverse folding device through the respective interaction of a folding knife of the folding knife cylinder 8 with the folding jaws of a folding jaw cylinder 9, and are then with a conveyor belt system 10 into a transverse folding device which consists of a folding knife cylinder 11 and a folding jaw cylinder 12 and executes the second transverse fold transferred and released by this in a manner not shown, for example into the delivery of the folder.
  • one of the folding knife and folding jaw cylinders 8; 9 and 11; 12 coordinated adjustment of the two working in pairs, with a perforating knife 13 and a perforating bar 14 for the first transverse fold and two perforating knives 15; 16 and two perforating strips 17; 18 equipped perforating cylinder 5; 6 required.
  • the perforating bar 14 I assigned to the first transverse fold is adjusted in the correct position, for which purpose both perforating cylinders 5; 6 I are made in two parts, ie the perforating bar 18 I and the perforating knife 16 I , each assigned to the second transverse fold, are arranged on one cylinder part 19 I and the perforating bar 14 I assigned to the second transverse fold is arranged on the other cylinder part 20 I of the perforating cylinder 6 I (Fig.
