Definitions

  • the invention relates to a method for operating a web-fed printing press according to the preamble of claim 1 or 8.
  • a printing material web is printed in several printing units. After printing, the or each printing material web is usually fed to a printing unit downstream Wendeied, wherein in the region of the turning structure at least one printed substrate web is divided into partial webs and the partial webs are preferably turned and / or offset.
  • the folding structure and thus the printing units is followed by a folding structure having at least one former for longitudinal folding of the partial webs.
  • the folding structure is followed by a folder, which are separated by cross-cutting of the partial webs copies in the folding machine. At least one longitudinal fold and / or one transverse fold is formed on the copies in the area of the folding apparatus.
  • the processing of the partial webs serving assemblies of the turning structure and / or Falz inconveniences are typically adapted to a fixed format of the printing material webs or partial webs. So far, it is not possible, during the printing process resulting width changes of a substrate web, be it an increase in the width of the substrate web as a result of a dampening agent entry or a reduction in the width of the printing substrate as a result of drying, compensate.
  • the present invention is based on the problem to provide a novel method for operating a web-fed printing press.
  • this problem is solved by a method according to claim 1. Thereafter, at least one printed substrate web prior to a longitudinal separation thereof and / or at least one partial web produced by longitudinal separation of the printed substrate web is metrologically detected in such a way that a measured width corresponding to the width of the printed substrate web is provided and, depending thereon, assemblies of the turnaround assembly and / or the folder assembly be adjusted.
  • this problem is solved by a method according to claim 8. Thereafter, at least one printed substrate web prior to a longitudinal separation of the same and / or at least one partial web produced by longitudinal separation thereof is detected such that a measured value corresponding to the width of the printed substrate web is provided and, depending thereon, the width of the printed substrate web influencing assemblies of the web press adapted become.
  • Both aspects can be used either alone or in combination with each other on a web press.
  • the present invention relates to a method for operating a web-fed printing press, the method according to the invention being described below with reference to FIG Fig. 1 for a preferred embodiment will be described by way of example.
  • Fig. 1 strongly schematized in a web-fed printing machine to be printed or printed substrate web, wherein the reference numeral 10 to be printed and therefore not yet printed substrate web and the reference numeral 10 'already printed substrate is characterized.
  • the printing material web 10 or 10 ' is transported in the direction of the arrow 11 by a web-fed rotary printing machine.
  • a transport path 12 of the printing substrate are not shown printing units positioned to print the still unprinted printing substrate 10 to form the printed substrate web 10 'at least on one side. Downstream of the transport path 12 is in Fig. 1 a drying device 13 positioned to dry the printed substrate sheet 10 '.
  • the printed and dried printing material web 10 ' is then fed to a turning assembly 14, wherein the printing substrate 10' by means of cutting means 15 of the turning structure 14 in the embodiment shown in three partial webs 16, 17 and 18 is separated.
  • the partial webs 16, 17 and 18 are fed via turning and offset rods 19 of the turning structure 14 to a former 20 of a folding structure 21.
  • the printing substrate is subject to a change in width.
  • a fountain solution entry during printing of the still unprinted printing material web 10 result in an increase in the printing material web width.
  • the printing substrate web width can shrink. This width change of the printing material web can lead to a lot of waste being produced. This can be avoided with the present invention.
  • assemblies of the turning assembly 14, namely the cutting devices 15 and the turning and offset rods 19, as well as assemblies of the folding structure 21, namely the former 20, can be adjusted, namely transversely to the transport direction of the printing material or the partial webs.
  • a sensor 22 by means of which the same immediately before the longitudinal separation of the printed substrate web 10 'can be measured to provide a reading across the width of the printed substrate sheet 10'.
  • assemblies of the turning structure 14 and / or assemblies of the folding structure 21 can then be adapted.
  • Fig. 1 In addition to the sensor 22, which is positioned immediately in front of the cutting devices 15, there is at least one further sensor 23 or 24 or 25, with the aid of which immediately after the separation of the printed substrate web 10 ', the width of at least one partial web 16 or 17 or 18 can be measured.
  • the senor 23 is used in particular for the metrological detection of the partial web 16
  • the sensor 24 serves for the metrological detection of the partial web 17
  • the sensor 25 serves for metrological detection of the partial web 18, whereby the width of the corresponding partial web is detected with each of the sensors 23 to 25 can.
  • the sensor 22 provides a measured value of the width of the printed substrate web 10 'and at least one of the sensors 23, 24 or 25 provides a measured value across the width of the respective sub-web 16 or 17 or 18, then based on these measured values and a predetermined division ratio for the separation of the printed substrate web 10 'or each cutter 15 transversely to the transport direction of the printing material 10' are shifted, in such a way that the actually achieved during L LucasstPark the printing material 10 'division ratio corresponds to the predetermined division ratio. In this way, a regulation for the longitudinal separation of the printed printing material web 10 'in partial webs 16 to 18 can be realized.
  • the width of an unprinted substrate web 10 can be subject to manufacturing fluctuations, it can be provided to further improve the method according to the invention, that the width of the unprinted substrate web 10 is determined by measurement using a further sensor 26, in which case from the metrologically determined width of the unprinted substrate web 10 and the metrologically determined width of the printed substrate web 10 'a difference between the width of the unprinted substrate web 10 and the width of the printed substrate web 10' is determined, and then based on this difference value and a predetermined division ratio for the separation of the printed substrate subassemblies Turning structure 14 and / or assemblies of the folding structure 21 are adapted.
  • the method according to the invention can be carried out both continuously during the entire production run or alternatively only at selected periods of printing, wherein if the process is carried out only in a selected period of the printing process, the same is carried out in particular if no stationary printing conditions are present. If stationary pressure conditions z. B. as a result of a constant dampening solution input and a constant dryer performance, it can be continued with the set to reach the steady state pressure conditions values after reaching the steady state conditions.
  • the metrological detection of the width of the printed substrate web 10 'and / or the metrological detection of the width of the partial webs 16, 17, 18 and / or the metrological detection of the unprinted substrate web 10 can be realized via an absolute measurement of the corresponding widths. Alternatively, it is possible to determine the corresponding widths by measuring a relative measurement by measuring at least one control mark printed on the printing substrate or partial webs.
  • the generation of waste can be drastically reduced, especially when starting up the printing process before stationary printing conditions are reached.
  • the inventive method can be done both fully automatically and semi-automatically, in a semi-automatic operation z. B. on the positioning of the cutting means 15 in a direction transverse to the transport direction of the printed substrate web 10 'can be accessed individually by a printer.
