Definitions

  • the invention relates to a web-fed rotary printing press, in particular web offset printing press according to the preamble of claim 7, as well as a folding apparatus therefor according to the preamble of claim 1 and a printing method according to the preamble of claim 11.
  • double-circumference plate cylinder can be operated at a speed of 45,000 - 50,000 plate cylinder revolutions / h, which, however, due to the double circumference compared to a comparable single circumferential printing machine twice as high, mobile with the printing press web speed or actual web speed of the machine, because now with one revolution of the plate cylinder four copy pages successive on the circumference of the plate cylinder can be printed in contrast to two on the cylinder of a single circumferential printing machine successive copy pages or heights.
  • a 32-page printed product or single copy are produced with a double-circumference printing at four-wide next to two identical or differently printed 16-page printed products when driven with collection production, that is if in the base folder a 16-page Druckvoreck (two copies heights) on the subsequent, also 16-sided Druckvoreck (two copy heights) is placed.
  • FIG. 2 shows a printing material web section corresponding to the circumference of a single-peripheral plate cylinder
  • FIG. 3 a section of a printing material web corresponding to the circumference of a double circumferential plate cylinder, with the individual sides of the end product to be produced drawn in as darkly shaded rectangles and with dashed lines the folding and cutting lines at which the printing material web is folded or cut in the folding apparatus.
  • the print (before) products are then fed out of the base folder without the use of a single circumferential plate cylinder, but possibly also when using a double peripheral plate cylinder (eg twice the same printed image on the plate cylinder) or, in the case of Figs Fig. 3 illustrated double circumference production - to produce printed products with double page number before leaving the Basisfalztechniks superimposed or collected, so that the print (end) product consists of two sheets ä two copy heights or ä two superimposed copy pages.
  • the individual copies leaving the basic folder can now be laid out on a delivery belt either in double format (eg DIN A3) or in overhead production directly via a delivery device, which usually has a paddle wheel be fed or a downstream station for introducing a so-called third fold or second Leksfalzes.
  • the second Leksfalzcut or station is in the FIGS. 2 and 3 symbolized with two arranged in the form of an inverted T lines.
  • the single copies are longitudinally folded for the second time to produce printed products with a simple format (eg DIN A4).
  • Means for introducing the second Leksfalzes today usually have a folding drum, in which a cycloid movement exporting shaft is rotatably received, on which a folding blade is mounted, which presses the copies between two opposing roles.
  • the second longitudinal folding step is preceded by a slowing station and a copy switch in the high-speed sleeve or double-circumference machines, at which the copies are divided into two devices for introducing the third fold.
  • a slowing station and a copy switch in the high-speed sleeve or double-circumference machines, at which the copies are divided into two devices for introducing the third fold.
  • the object of the present invention is therefore to provide a web-fed rotary printing machine and a folding apparatus therefor and a suitable printing method with which the abovementioned disadvantages of printing presses are overcome whose maximum operating speed is higher than the folding clock of their second longitudinal folding devices.
  • the inventor has recognized that it is also in web-fed rotary printing machines in which the plate cylinder rotational speed is not the limiting factor for the maximum possible web speed, but the folding cycle in the second L Lucassfalzhand, ie in web-fed rotary printing machines, where one by a maximum plate cylinder rotational speed or other machine size in the run the folding apparatus certain maximum printing material web speed higher than the maximum folding cycle provided in the second Lssensfalzhand, a Basisfalzwerk the printing press downstream second Lfitsfalz liked, even when using only one of the Basisfalztechnik downstream second Lssensfalz friendship succeeds in most types of production, with the high, only by the plate cylinder speed Limited maximum pressure material web speed to drive.
  • the printing material web speed and the actual web speed which are important in the context of the invention, is the web speed in the folder inlet, thus e.g. after the former or hopper construction and not a locally accelerated or decelerated web speed, as occurs, for example: between the cutting cylinder pair and Greiferfalzzylinder in Greiferfalztechniken or after passage of the folding unit downstream slowdown station.
  • the invention is particularly suitable for use in double circumferential printing units or units or printing machines with one or more such double peripheral printing (printing units in which the plate cylinder has a double circumference), because here high web speeds of over 75,000 copies / h, in some cases from to to 50,000 plate cylinder revolutions / h, which corresponds to 100,000 copies / h, can be driven, and with high print quality.
  • the invention can also be used in the case of single-circumference sleeve cylinders in the printing unit, which can be operated at up to 85,000 cylinder revolutions per hour, although with lower print quality.
  • copies / h is based on the Druckstoffbahn (2012) within the scope of the application on a 16-page product or copy, find its two copy heights on a single circumference or half a double circumference place.
  • the invention can also be applied to wider printing presses on which copies of more than four pages wide can be produced, e.g. 24-, 32- and up to 80-page copies.
  • a conceivable cylinder ratio for a base folder used in a folder according to the invention would be for example 1: 5: 5. However, preference is given to a cylinder ratio of 2: 5: 5 or even 3: 5: 5 or 4: 7: 7, as it is already used in today's high-speed machines.
  • the Basisfalzwerk and the single second Lijnsfalz coupled can be interposed a slowing down station, which can be equipped in a conventional manner with a camshaft and an opposite counter-roller. This slowdown station serves to slow down the copies coming out of the basic folder, and then feed them to the second longitudinal folder with lower kinetic energy. The gap between the copies coming out of the basic folder and the collective production is used as a braking path.
  • the folder has a folding superstructure with at least one funnel for longitudinal folding of the printing material web or of the stitching strand which possibly enters the folding apparatus and may consist of several printing material webs.
  • the invention can also be used in balloon funnel structures or hoppers arranged side by side. Also conceivable would be a magazine assembly of the folder.
  • FIG. 1 shows a folding apparatus, which is designated overall by 1 and has a Leksfalztrichter 2 in the hopper structure over which the printing material is guided over a series of unspecified train and optional perforating roller pairs in a folder or Basisfalztechnik, which total of 3 is designated.
  • the invention can also be used in a folder with magazine structure.
  • the Basisfalzwerk 3 in this case has a cutting blade cylinder 11, opposite to a NOTEurfalzzylinder 12 is arranged.
  • the printing substrate is cut into individual copies, in the present embodiment, the cutting blade cylinder 11 has a double circumference and thus two cutting blades per circumference, at the same speed as a double circumferential plate cylinder in the upstream printing unit two copies ( or in case of collection production copies) per revolution.
  • the copies or copies bills are punctured by means of puncturing needles on the five-fold NOTEurfalzzylinder 12, which also serves as a collection cylinder for collecting several copies to be placed on each other in collective production.
  • the copies are transferred to a jaw cylinder 13, wherein the transverse fold in the respective copy is introduced.
  • Above the jaw cylinder 13b is an optional further cylinder 14 for introducing a second transverse fold (e.g., delta or double parallel production).
  • a second transverse fold e.g., delta or double parallel production.
  • Below the ceremoniurfalzzylinders is an optional stapling cylinder 15.
  • the jaw cylinder 13 also has a fivefold large circumference.
  • the Quergefalzten, collected or collected unsorted individual copies of a conveyor belt assembly are fed between the bands of the individual copies of the Basisfalztechnik 3 downstream slowdown station 5 are supplied, which is equipped with a camshaft and an opposite mating roll.
  • the incoming single copies are slowed down accordingly, to supply them to the downstream second longitudinal seaming stage in the correct cycle with low kinetic energy.
  • This second longitudinal folding step would normally have two second longitudinal folding devices each loaded with a half copy number via a copy diverter.
  • the second Leksfalzch of the folder 1 only a single second Leksfalz adopted 7, which is fed directly with the desired second Leksfalz coming from the slowing station 5 copies.
  • the second longitudinal folding device 7 in this case has a folding drum arranged on the upper side with a folding blade shaft which carries out cycloidal movements with a folding blade which presses the single copies between two rollers arranged underneath, from where they reach a paddle wheel 8, via which the latter is provided with a second longitudinal fold Copies are designed on a product display.
  • the second longitudinal folding device 7 can also be switched off and the copies coming from the product slowing station 5 are not provided with a second longitudinal fold, but instead are fed past the second longitudinal folding device 7 to a paddle wheel 9, via which they are laid out on a product display intended for overhead production become.
  • a corresponding higher-level control is advantageously provided, which specifies the right maximum speed for the plate cylinder speed or a leading axis of the printing press for each set production, to which the printing units and / or the folding unit are synchronized.
  • the printer can then set a setpoint for the machine speed or the speed of a machine speed predetermining master axis, which keeps within the specified limits.
  • FIGS. 2 and 3 are merely explanatory diagrams and show no specific features of an embodiment of the invention, reference is made to the introduction to the description.
