Definitions

  • the invention relates to a method for operating a web-fed rotary printing press according to the preamble of claim 1.
  • a web-fed rotary printing machine also has at least one turning structure, at least one folding structure and at least one former.
  • at least the turning structure and the folding structure of a web-fed rotary printing press are typically designed for processing at least one full-width printing material web, which comprises a defined number of printed pages juxtaposed with a first page width.
  • the printed pages have a first page width.
  • four juxtaposed printing pages having printing material web of the web-fed rotary printing press typically has two formers, depending on whether the printing material with the four juxtaposed printed pages in two sub-webs or for tabloid production in four sub-webs is separated in the formers either L jossfalze or for tabloid production no longitudinal folds are formed. From practice, it is also known that the formers are mutually displaceable to adjust the lateral distance between them, namely between funnel tips thereof.
  • the present invention is based on the problem to provide a method for operating a web-fed rotary printing press, with which despite the design of the web-fed rotary printing press on a first page width and products with a second page width, which is greater than the first page width can be produced.
  • This problem is solved by a method according to claim 1.
  • the printing material web guided centrally through the turning structure and separated into three sub-webs with the same width, the two outer sub-webs without a turn of the same for tabloid production on outer funnel legs side former are performed, and wherein the middle part of web is laterally offset on turning bars, that the middle part of the web is guided together with one of the two outer partial webs on the corresponding outer funnel leg of the corresponding lateral Forming.
  • the invention makes it possible, on a web-fed rotary printing press, which is designed to process at least one full-width printing material web, which comprises four printing pages juxtaposed with a first page width, to also process at least one printing material web, the three printed pages juxtaposed with a second page width, the greater than the first page width.
  • the printing material web is guided centrally with the three juxtaposed printing sides of the second side width through the turning structure and separated into three sub-webs with the same width, the two outer sub-webs run straight and moved to their position, outer hopper side folding former are performed, whereas the middle sub-web laterally offset over turning bars and optionally combined together with one of the two outer sub-webs and is performed together with the same over the corresponding outer funnel leg of the corresponding lateral Former.
  • the present invention relates to a method for operating a web-fed rotary printing press with a plurality of printing units, at least one turning structure, at least one folding structure and at least one folding apparatus.
  • At least the turning structure and the folding structure of the web-fed rotary printing press are designed for processing a full-width, format-variable printing material web, which comprises four printed pages juxtaposed with a first, maximum page width.
  • FIG. 1 shows Fig. 1 in an upper half 10 a schematic section of a web-fed rotary printing press in the region of a turnaround 11 and a folding structure 12, wherein the folding structure 12 comprises two formers 13, which are designed to process a full width substrate web 14 with four juxtaposed printed pages of the maximum page width a.
  • At least the formers 13 are mutually displaceable in their relative position, so that a lateral distance between the hopper tips 15 of the two formers 13 can be changed.
  • the formers 13 are designed as a so-called combed formers, which can be pushed into each other at least in sections.
  • the present invention now proposes a method with which a printing material web can be processed to provide greater format variability, comprising three printing pages juxtaposed with a second page width, the second page width being greater than the first, maximum page width. This will be described below with reference to the lower half 20 of Fig. 1 described.
  • the printing material web 21 is guided centrally with the three juxtaposed printing sides of the second side width b through the turning structure 12 and separated via the outer cutters 16, which are displaced by the amount .DELTA.x in three partial webs 22, 23 and 24, wherein each of these partial webs 22nd , 23 and 24 has an equal width corresponding to the second side width b.
  • Fig. 1 can be removed to shift the production between the substrate web 21 with the three juxtaposed print pages of the second page width b and the printing substrate 14 with the four juxtaposed printed pages of the first page width a not only the outer cutters 16 displaced by the amount .DELTA.x, but rather are also the funnel tips 15 of the two former 13 displaced by the amount .DELTA.x relative to each other.
  • Ax 0 . 5 * 2 ⁇ a - b
  • Fig. 1 can be removed, the two outer partial webs 22 and 24 are performed without turning and thus straightforward on the outer funnel legs 18 of the two former 13 in the processing of the printing material web 21 with the three juxtaposed printed pages of the second page width.
  • the middle part of the web 23 is turned on turning bars 25 and laterally offset by the amount of the second side width b, that the middle part of web 23 is guided together with one of the two outer part webs on the corresponding outer funnel leg 18 of the corresponding former.
  • the middle part of the web 23 is offset by the amount of the second side width b to the left, so that the middle part of web 23 is guided together with the outer part of web 22 on the outer left hopper leg 18 of the left former 13.
  • the middle sub-web 23 is offset by turning bars 25 by the amount of the second side width b to the right, so that then the middle sub-web 23 is guided together with the outer sub-web 24 on the outer right funnel leg 18 of the right former 13.
  • the embodiment of the Fig. 2 with the embodiment of Fig. 1 the same reference numbers are used to avoid unnecessary repetitions for the same elements.
  • FIG. 3 and 4 show Fig. 3 and 4 such as Fig. 5 and 6 , wherein the embodiments of the Fig. 3 . 4 as well as the Fig. 5 . 6 from the embodiments of the Fig. 1 . 2 differ only by the total widths of the substrates.
  • the total width of the substrate web 21 with the three juxtaposed print pages of the second page width b of the total width of the substrate web 14 with the four juxtaposed printed pages of the first page width a corresponds to the total width of the substrate web 21 with the three juxtaposed print pages of the second page width b of the total width of the substrate web 14 with the four juxtaposed printed pages of the first page width a.
  • the total width of the printing material web 21 with the three printing pages of the second page width b positioned next to one another is smaller than the total width of the printing material web 14 with the four printing pages of the first page width a positioned next to one another.
  • All embodiments have in common that on a web-fed rotary printing press, which is designed to process a full-width substrate web with four juxtaposed print pages of the first page width a, also a printing substrate with three juxtaposed printed pages of the second page width can be processed, the second page width is greater as the first page width.
  • the printing material web with the three juxtaposed pressure sides of the second side width b is guided centrally through the turning structure and separated into three equal sub-webs, the two outer sub-webs run straight without turning and laterally offset the middle sub-web over turner bars and with one of the two outer sub-webs is united.
  • the partial webs extend to the tabloid production via outer funnel legs of relatively movable folding formers, wherein the outer funnel legs 18 of the former 13 are extended with respect to the inner funnel legs 19 thereof.
  • the formers and cutting devices are displaceable relative to one another, namely transversely to the transport direction of the printing material webs or partial webs.
