Definitions

  • the invention relates to a folding device with a device for transverse perforation on the fold back of fold copies, in which the perforation is applied to the fold product before folding.
  • a folding mechanism with a device for transverse fold perforation on the fold back of fold copies in which the perforation is applied to the sheet before folding.
  • the folding knives are equipped with perforation teeth and a counter roller 2 with a perforation groove is attached to the collecting cylinder.
  • this known folding unit it is only possible to produce a transverse perforation on the fold back of the first transverse fold.
  • the invention makes it possible in a simple manner to interlock the layers of the products in the second transverse fold. This is particularly advantageous if the folded copies are produced as book sections that are later fed to an adhesive connection. This type of cross perforation is likewise advantageous if the strands entering the folder cannot be connected by a so-called funnel fold. In the case of generally known folding apparatuses, both the transverse fold perforations for the first and for the second fold were produced on the strand, that is to say on the incoming web, which entailed various disadvantages, inter alia with regard to the processing accuracy.
  • One or more printing material webs 1 lying one above the other are fed via a pair of pull rollers 2 to a puncturing and folding knife cylinder 5 which is equipped with punctures 6 and folding knives 7.
  • the printing material web 1 is cut to the desired product or specimen length on the puncturing and folding knife cylinder 5 by a knife cylinder 3 provided with knives 4 thereon.
  • the product sections are partially guided around the latter by means of the punctures 6 of the puncturing and folding knife cylinder 5.
  • the folding copies 7 insert the folding copies into folding jaws 9 of a folding jaw cylinder 8 positioned on the puncture and folding jaw cylinder 5, whereby the first transverse fold is produced.
  • the folding jaw cylinder 8 is of a very simple construction and, in addition to the mentioned folding jaws 9, only has one perforating groove 10.
  • a gripper and folding knife cylinder 11 is arranged behind the folding jaw cylinder 8 and has the gripper 12 and folding knife 13. With the help of the grippers, the copies which have already been folded once on the folding jaw cylinder 8 are transferred to the gripper and folding knife cylinder 11. Now, in the manner according to the invention, a transverse perforation is produced on the fold back before the second transverse fold to be subsequently produced. This is done in that the folding knives 13 of the gripper and folding knife cylinders 11, which are designed as perforating knives, are controlled against the perforating groove 10 of the folding jaw cylinder 8, as a result of which the perforation rests on the gripper and folding jaw cylinder Copy is generated.
  • the second transverse fold is then produced, in which the folding knives 13 push the specimens lying on the gripper and folding knife cylinder 11 into folding jaws 16 of a gripper and folding jaw cylinder 14 arranged behind the gripper and folding knife cylinder 11.
  • the copies are delivered, for example to a ribbon line 17.
  • the puncturing and folding knife cylinder 5 can also be designed as a collecting cylinder in order to collect and fold copies of specimens cut onto the first transverse fold before it is produced. If no second transverse fold is required, no perforation is produced between the cylinders 11 and 8, i.e. the folding knives 13 designed as perforating knives are not controlled against the perforating groove 10.
