Definitions

  • each printing unit two blanket cylinders form a press nip, through which the web-shaped or sheet-shaped printing material is passed and the printing material takes over the printed images from the rubber blanket cylinders.
  • the water or detergent liquid is on the pressure gap inlet side sprayed on the blanket cylinder and squeezed into the printing material in the printing nip.
  • the water or the detergent liquid removes printing ink, paper residues and other dirt from the blanket cylinders and transfers them to the printing substrate, which removes them.
  • a wash cloth can also be provided, which is placed on the blanket cylinders during the washing process and wipes off the loosened dirt.
  • An automatic dosing device doses a certain amount of liquid which the nozzles 2 and 4 move during their transverse movement over the transverse movement path or in a certain transverse position onto the associated blanket cylinder 26, in the case of the nozzles 2 and 4 of the dryer 9 onto the printing substrate 12, spray.
  • This automatic dosing device contains a separate storage line 50 for each nozzle 2 and 4 for storing the dosed amount of liquid.
  • the storage line 50 is connected at its downstream end in terms of flow to the associated nozzle 2 or 4 and at its upstream end via a branch 51 to two valves 52 and 54. By opening the one valve 52 with the other valve 54 closed, the storage line 50 is filled with liquid, the amount of which depends on the supply pressure Liquid and the opening time of the valve 52.
  • the compressed air valves 54 are connected to a compressed air source 59 via a pressure regulator 58.
  • the liquid valves 52 are connected to a liquid source 60.
  • the liquid supplied from the liquid source 60 to the liquid valves 52 can be water, solvent, another washing liquid or a composition of several such components.
  • the liquid source 60 preferably contains means for selectively dispensing water alone or for dispensing other washing liquid or for mixing water from a water reservoir 61 and a detergent from a detergent reservoir 62. This mixing and supplying of liquids from the liquid source 60 can also be timed by the control device 56 and controlled in terms of quantity.
  • the control device 56 preferably contains a plurality of operating programs which carry out the control processes mentioned as a function of desired setpoints.
  • Each nozzle 2 or 4 moves in a very short time, preferably in less than a second, transversely to the longitudinal direction of the machine over the area of the blanket cylinder 26 or the printing material 12 to be moistened. This time is sufficient for the metered amount of liquid to be uniform over the entire transverse movement path To spray 36 and 38 distributed.
  • An important advantage of the invention is that even very small amounts of liquid can be distributed evenly over a large area of the machine cylinder or of the printing material by using only a very few, preferably only a single nozzle for each area to be moistened. The accuracy of the metering is further improved if the liquid is metered in a storage line 50 in accordance with the above embodiment and then only the metered amount of liquid is sprayed.
  • the locally adapted moistening essentially focuses on the printing material edges, on selected areas corresponding to the ink-guiding ink zones and on areas or stains that are limited to the side and in the printing direction. If an axially lying section of a part of the width of the roller or the cylinder is exposed for a longer period, the moistening zone is shown as a strip. If the nozzle moves, the strip is not parallel to the printing direction, but runs in the side due to the lateral offset Angle to the printing direction, for example, like an angled helix.
  • the strip to be imagined shortens as an image of the moving surface to an area that is limited in the direction of development, or a section of the area that can ideally be represented as a rectangle.
