Definitions

  • the invention relates to a device for cross-folding webs of a rotary printing press according to the preamble of claims 1 and 4.
  • Products folded to a third of the format length of the printing press are mainly processed in book production.
  • a folder for such products is shown in EP-B1-19 202, Fig. 5. Then the web is cut between a knife cylinder and a puncture and folding knife cylinder in format length. During the subsequent transfer into the jaw of a jaw cylinder, the sheet is folded in a 2/3 to 1/3 ratio. When it is then passed on to the folding jaw of another folding jaw cylinder, a second transverse fold is made to a third of the format length.
  • this device has the advantage that the punctures are on the outside, thus working with pre-fold and the removal of the punctures required in book production can take place with little loss of cut.
  • the device has the disadvantage, however, that when the first transverse fold is formed, two thirds of the sheet must be pulled off the puncturing and folding knife cylinder against the direction of rotation thereof, and the working speed of the folding device is thereby limited.
  • a folding device is also known (Braun, Atlas of Newspaper and Illustration Printing, Polygraph Verlag GmbH, Frankfurt am Main, 1960, p. 95), in which the web is first cut in format length between a knife cylinder and a puncturing and folding knife cylinder. If the working elements are arranged accordingly, the sheet can then be folded to two thirds of the format length when it is transferred to the folding jaw of a folding jaw cylinder. The folded sheet is then transferred to the grippers of a gripper and folding knife cylinder. In the Subsequent transfer to a folding jaw of the folding jaw cylinder, the sheet is folded to a third of the format length.
  • the device avoids pulling off two thirds of the arc length counter to the direction of rotation of a cylinder, it is nevertheless limited in working speed due to the use of the gripper. Furthermore, the punctures are inside the folded product, which means that the cut loss is high for their removal.
  • the invention has for its object to provide a device for cross-folding webs of a rotary printing press to a third of the format length with a knife cylinder, a puncturing and folding knife cylinder and a folding jaw cylinder, which creates products with external punctures, doing without gripper-equipped cylinders and none pulls long bends from cylinders against their direction of rotation.
  • This object is achieved in a generic device by the characterizing features of claim 1. This cuts the web in a 1/3 to 2/3 ratio, and then the two sections are placed on top of one another and provided with a cross fold. Only a third of the format sheet is pulled off a cylinder against the rotational movement, thus allowing the folding device to work at high speed. Furthermore, the punctures of both sections are on the outside and thus allow their low-loss section.
  • the object is also achieved by the characterizing features of claim 4.
  • the web is first cut into format sheets. These are then divided in a 1/3 to 2/3 ratio. Then the two sections are placed on top of each other and provided with a cross fold.
  • the pre-fold is advantageously adjustable using the characterizing features of claims 2 and 3 or 5.
  • the transverse folding device shown in Fig. 1 contains a knife cylinder 1 with a circumference in the size of the format length. It is equipped with two cutting blades 2; 3 with a circumferential distance of one third of the format length.
  • the knife cylinder 1 works together with a puncture cylinder 4, which has three times the circumference of the knife cylinder 1 and three pairs of puncture systems 5; 6 contains, the latter each having a circumferential distance of one third of the format length.
  • a further puncture cylinder 9 and a puncture and folding knife cylinder 10 are arranged one after the other on the puncture cylinder 4 in the direction of rotation thereof according to the knife cylinder 1.
  • the puncture cylinder 9 carries four puncture systems 11, each at a distance of one third of the format length from one another.
  • the puncture and folding knife cylinder 10 has twice the circumference of the knife cylinder 1 and is equipped with two puncture systems 12 and folding knives 13, the latter having a circumferential distance of one third of the format length from the puncture system adjacent in the direction of rotation.
  • the puncture and folding knife cylinder 10 is followed by a folding jaw cylinder 14 with two folding jaws 15 on a circumference comprising two format lengths.
  • a former 16 By means of a former 16, e.g. once length-folded web 17 is fed to the cross-folding device via pull rollers 18.
  • the web 17 is cut in the center of the knife cylinder 1 and the puncture cylinder 4 by the cutting knives 2 and 3 in conjunction with the cutting grooves 7 and 8 into sections A and B with lengths of one third and two thirds of the format length. These are needled by the puncture systems 5 and 6 of the puncture cylinder 4.
  • sections A are taken over by the point systems 11 of the point cylinder 9 in the center of the point cylinder 9.
  • the latter delivers the sections A again to the puncture cylinder 4 during its next rotation, these being taken over by the puncture systems 6 and coming to rest on the sections B.
  • the sections A and B are taken over by the puncture systems 12.
  • sections A and B in the center of the folding jaw cylinder 14 are pressed into the folding jaws 15 by means of the folding knife 13 and thereby provided with a first transverse fold.
  • Section A is now wrapped in section B and the punctures 19 of the finished product 20 (FIG. 2) are on the outside.
  • the pre-fold 21 can be adjusted by adjusting the cutting knife 2; 3, puncture systems 5; 6 and folding knife 13 and puncture systems 12 can be adjusted to each other.
  • the folded product 20 can be fed to a bucket wheel boom 23 via a guidance system 22 or to a second longitudinal folding device 25 by means of a belt line system 24.
  • Fig. 3 shows a cross folding device with a knife cylinder 26 with a circumference in the size of the format length. It is equipped with a cutting knife 27 and works with a puncture and knife cylinder 28. This has three times the circumference of the knife cylinder 26 and contains three cutting knives 29 and puncture systems 30, the latter having a circumferential distance of one third of the format length from the cutting knife 29 adjacent in the direction of rotation. Cutting grooves 31 are assigned to the puncture systems 30. On the puncture and knife cylinder 28 are in it Direction of rotation after the knife cylinder 26, a puncture cylinder 32 and a puncture and folding knife cylinder 33 are arranged in succession. The puncture cylinder 32 carries four puncture systems 34, each at a distance of one third of the format length from one another.
  • the puncture and folding knife cylinder 33 has twice the circumference of the knife cylinder 26 and is equipped with two puncture systems 36 and folding knives 37, the latter having a circumferential distance of one third of the format length from the puncturing system 36 which is adjacent in the direction of rotation.
  • the puncture and folding knife cylinder 33 is followed by a folding jaw cylinder 38, which has a circumference of two format lengths and carries two folding jaws 39.
  • the web 41 which has been folded longitudinally once by means of a folding former 40, is fed to the cross-folding device via the pull rollers 42.
  • the web 41 is cut in the center of the knife cylinder 26 and the puncturing and knife cylinder 28 into sheets with the format length.
  • the sheets are needled onto the puncture systems 30 and, during further rotation of the puncture and knife cylinder 28 in the center with the puncture cylinder 32 by means of the cutting knives 29 and the cutting grooves 35, cut into sections A and B with lengths of one third and two thirds of the format length . While the sections A are taken from the puncture cylinder 32 by means of the puncture systems 34, the sections B remain on the puncture and knife cylinder 28.
  • the puncture cylinder 32 delivers the sections A again to the puncture and knife cylinder 28 during its next rotation, whereby these pass from the puncture systems 30 are adopted and come to rest on the sections B.
  • sections A and B are taken over by the puncture systems 36.
  • sections A and B in the center of the folding jaw cylinder 38 are pressed into the folding jaws 39 by means of the folding knife 37 and thus provided with a first transverse fold.
  • the result is the product 20 shown in FIG. 2.
  • the pre-fold 21 can be adjusted by adjusting the cutting knives 29 and the puncture systems 30 or the folding knife 37 and the puncture systems 36 can be adjusted to one another.
  • the folded product 20 can in turn be fed to a bucket wheel boom 44 via a guidance system 43 or to a second longitudinal folding device 46 by means of a ribbon line system 45.
  • the selected size ratios of the cylinders are only exemplary embodiments. Other scopes can also be selected within the scope of the invention, e.g. for the knife cylinder a double, the puncture cylinder 4 or the puncture and knife cylinder five times, the puncture and folding knife cylinder three times and the puncture cylinder 9 or 32 five thirds of the format length.
