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 press in addition to a plurality of printing units, further comprises a turning structure, a folding structure and a folding apparatus.
  • the turning structure and the folding structure of a web-fed rotary printing press are designed for the production of a full-width, non-variable-format printing material web, which comprises a defined number of printed pages juxtaposed with a first page width.
  • the folding structure usually comprises two juxtaposed, stationary formers.
  • the folder assembly usually has three stationary folder hoppers positioned next to each other.
  • a full-width substrate web with four print sides juxtaposed with the first page width can be separated in the middle in two part paths if required in the turnaround structure.
  • a full-width substrate web with six juxtaposed printed pages of the first page width can be separated if necessary in turning construction in up to three sub-webs.
  • the present invention is based on the problem to provide a method for operating an actually not variable-format web-fed rotary printing press, which despite the design of the web press on a first page width and products with a second page width, which is greater than the first page width produced can.
  • the partial width printing material web is guided centrally through the web-fed rotary printing press to the turning structure and separated centrally into two partial webs each sub-web is laterally offset to turning bars at least by the simple amount of the first page width, that the sub-webs are led to the tabloid production on the outer funnel legs side former.
  • a partially wide printing material web which has a defined number of times, on a web-fed rotary printing press which is not format-variable and which is designed to process a full-width printing material web which comprises a defined number of printed pages with the first page width positioned side by side side by side positioned printing pages with the second page width includes to process, wherein the second page width is greater than the first page width.
  • Each of these partial webs is offset laterally on turning bars by at least the simple amount of the first side width, so that partial webs for tabloid production are guided over the outer funnel legs of the lateral folding funnels.
  • the present invention relates to a method for operating an actually non-variable-format web-fed rotary printing press, wherein a web-fed rotary printing press comprises a plurality of printing units, a turning assembly, a folding assembly and a folding apparatus. At least the turning structure and the folding structure of such a web-fed rotary printing press are usually designed for processing a full width printing material web, which comprises a defined number of printed pages juxtaposed with a first page width.
  • the method according to the invention it is now possible to process a partially wide substrate web on such a non-variable-format web-fed rotary printing press, wherein the partial-width substrate web comprises a defined number of printed pages juxtaposed with a second page width greater than the first page width.
  • Fig. 1 shows a schematic section of a web-fed rotary printing press in the region of a turning structure 10 and a folding structure 11, wherein the turning structure 10 and the folding structure 11 is designed for processing a full-width substrate web 12, which in the embodiment of Fig. 1 includes four juxtaposed printed pages with the first page width a.
  • a full-width substrate web with four juxtaposed print sides of the page width a is usually performed centrally through the turning structure and, if necessary in the turning structure by means of a cutter 13 centered in z.
  • each sub-web comprises a width corresponding to the first page width a, and in which then in the formers 14 are formed in the sense of a tabloid production no longitudinal folds.
  • the invention now relates to a method with which on such, actually not format variable web-fed rotary printing press, the processing of the full-width substrate web 12, in the embodiment of the Fig. 1 includes four juxtaposed printed pages of the first page width a, also a partial width substrate web can be processed, which comprises a defined number of juxtaposed printed pages with a second page width b, which is greater than the first page width a.
  • Fig. 1 includes a partial width substrate web 15 two juxtaposed printed pages with the second page width b, wherein the amount .DELTA.x illustrates the difference between the second page width b and the first page width a.
  • the part width printing material web 15 with the two printed pages of the second page width b is centered by the printing press led to the turnaround 10 and separated centrally by means of the cutter 13 into two partial webs 16, 17.
  • Each of the partial webs 16, 17 then comprises a width which corresponds to the second side width b.
  • Each of the partial webs 16, 17 is in the region of the turning structure on each two turning bars 18 (see also Fig. 5 ) deflected such that each of the partial webs 16, 17 in the embodiment of Fig. 1 is offset laterally by the simple amount of the first side width a, so that each of the partial webs 16, 17 is guided for tabloid production on outer funnel legs 19 of the former 14.
  • the left partial web 16 is passed over the left outer funnel leg 19 of the left former 14 and the right part web 17 is passed over the right outer funnel leg of the right former 14, wherein, as Fig. 1 can be removed, the outer funnel legs 19 are formed longer than the inner funnel legs of the former 14th
  • the inner funnel legs 20 have a length which is designed for the first side width a.
  • partial webs with the larger, second side width b can also be guided over the outer funnel legs 19.
  • Fig. 2 shows a second embodiment of the present invention, wherein the embodiment of the Fig. 2 from the embodiment of Fig. 1 merely signed by the fact that the formed after the separation of the part width printing substrate 15 left partial web 16 on the outer right funnel leg of the right former 14 and formed after separation right partial web 17 on the left outer funnel leg 19 of the left former 14 is performed.
  • it is also possible to turn both partial webs so that both partial webs are guided either over the right outer funnel leg or the left outer funnel leg.
  • Fig. 3 and 4 show embodiments of the method according to the invention, in which the web-fed rotary printing press is designed for processing a full width substrate web 12, the six adjacent juxtaposed printed pages with the first page width a, wherein such a web-fed rotary printing press three juxtaposed, fixed formers 14 includes. Also on such a web-fed rotary printing press, a part-width printing material web 15 can be processed, in accordance with Fig. 3 and 4 two juxtaposed printed pages with the second page width b includes, wherein the second page width b is greater than the first page width a.
  • This partial width substrate web 15 is guided centrally through the printing press to the turnaround assembly 10 and centered in the turning structure 10 in two partial webs 16, 17 of the width b, wherein the partial webs 16, 17 in the embodiment of Fig. 3 be offset laterally on the turning bars 18 by twice the amount of the first side width a.
  • it is also possible here to turn both partial webs so that both partial webs are guided either over the right outer funnel leg or the left outer funnel leg.
  • a web-fed rotary printing press which in principle is not variable in format but rather to process a full-width substrate web with a defined number of printed pages juxtaposed, which have a first page width, to process a partially wide substrate web, which has a defined number of printed pages juxtaposed with a second page width, wherein the second page width is greater than the first page width, and further wherein the total width of the full-width substrate web with the defined number of print pages of the first page width is greater than the total width of the part-wide substrate web with the defined number of printed pages of the second page width.
  • the former 14 can be fixed and therefore rigid.
