Definitions

  • the invention relates to a rotary printing press system according to the preamble of claim 1.
  • rotary printing presses with a large product variability are required, which make it possible to achieve high utilization and thus economic efficiency by producing different products. This results, for example, in weekly recurring production requirements with several daily product changes.
  • the products to be produced to achieve a high utilization of a rotary printing press can be both with regard to their composition of heat and / or coldset webs and placement of the respective webs in the product, as well as with regard to their format, such as page size, page number, folding arrangement, strongly different.
  • the investment costs are formed, among other things, by the size of the required production premises or halls, whereas the operating costs are composed, inter alia, of personnel costs for the operation of a rotary printing machine as well as personnel expenses for product changes.
  • downtimes in the event of disruptions occurring, caused, for example, by web breaks, are also included in the production costs.
  • the WO 2007/020288 A1 a rotary printing machine, which is a first, intended for the production of newspaper products machine line with at least two printing towers and one aligned with the Printing towers arranged first former hopper assembly, and a second machine line with at least one second printing tower, arranged in the second machine line in alignment with the second printing tower heatset, and arranged in alignment with the second printing tower and the heatset, the second formers.
  • the first machine line is rotated by 90 ° with respect to the first machine line.
  • a heatset web printed in the second machine line and guided by the heatset is deflectable by 90 ° by means of a turning bar arrangement from a transport direction perpendicular to the first machine run and can be guided in a transport direction parallel to the first machine run.
  • WO 2004/024448 A1 is a rotary printing machine with a plurality of printing units, at least one heatset and at least one folding unit known in which at least one printing unit is arranged relative to the axial direction of its cylinder next to another printing unit.

  • each subsection has a turning bar arrangement for the individual transfer of printed in a machine line heat and / or coldset webs or partial webs in at least one parallel machine line, so that in other productions in the subsections independently printed heat and / or coldset Webs in one or more simultaneously producible products as desired are placeable.
  • each of the machine lines arranged in parallel and formed by the subsections has its own folding unit and in that each machine line has a turning bar arrangement for the individual transfer of individual webs or partial webs printed between the machine lines with the subsections, it is possible to to supply the webs or partial webs printed in the subsections individually and independently of one another to any folding mechanism.
  • the page number of a first product to be produced does not fully utilize the capacity of a first subsection, the possibility arises to supply a web or sub-web printed by that first subsection to another folder for producing a second product which may be independent of the first.
  • a high utilization of the printing units of the rotary printing machine is achieved.
  • Another advantage of this arrangement is that in case of failure of a folding unit of a subsection production does not come to a standstill, but by the turning bar assembly which can be fed from the affected by the partial section partial printed sheets or partial webs a folder of other subsections.
