Definitions

  • the invention relates to an offset rotary printing machine with at least two partial printing units for supplying one color each to the print carrier, in which the blanket cylinders of all partial printing units are arranged in contact for ink transfer in series, so that the blanket cylinder of a partial printing unit, in addition to the color of the plate cylinder assigned to it, the color (s) or the further rubber cylinder / s can be fed and in which a pressure cylinder pressing the printing medium against a rubber cylinder is provided.
  • the invention is based on the object, while maintaining the ink collecting principle according to the patent application mentioned, to further develop a printing press of the type mentioned at the outset in such a way that production is increased without increasing the peripheral speed of the cylinders.
  • the sheetfed offset printing machine comprises five partial printing units, each with a blanket cylinder 1, 2, 3, 4, 5.
  • a plate cylinder 6, 7, 8, 9, 10 is assigned to each blanket cylinder.
  • An inking unit 11, 12, 13, 14, 15 and a dampening unit 16, 17, 18, 19, 20 can be set on each plate cylinder. If only the dry offset process is to be used for printing, the dampening units can be omitted.
  • a pressure cylinder 21 is assigned to the blanket cylinder 5.
  • Deflection wheels for a chain system 22 with grippers are arranged on the axis of the pressure cylinder 21.
  • the grips of the chain system 22 are transferred to a sheet by means of a pre-gripper 24 on a feed table 23 in the direction of arrow a.
  • the sheets are partially guided around the printing cylinder 21 by means of the chain system 22, the printing taking place. The sheets are then removed for delivery.
  • a pressure cylinder 25 is provided, on the axis of which deflection wheels for a chain system 26 are in turn fastened with grippers.
  • the grippers of this chain system are supplied with sheets via a feed table 27 and a pre-gripper 28 in the direction of arrow b.
  • the printing cylinder 25 is assigned, in particular for reasons of accessibility to the parts of the printing press, to the blanket cylinder 1, which is located at the end of the blanket 5 opposite the blanket cylinder
  • Rubber cylinder row is located.
  • the sheets guided by the chain system 26 receive a pressure between the impression cylinder 25 and the blanket cylinder 1 and are then carried on to the delivery.
  • the rubber cylinders 1 to 5 are placed next to one another to carry out a print.
  • Each blanket cylinder receives a partial print image in one color from the plate cylinder assigned to it. Since the rubber cylinders touch each other, they pass on the partial print images taken from the plate cylinder assigned to them to the neighboring rubber cylinders.
  • a complete five-color print image is therefore built up on all blanket cylinders 1 to 5.
  • five-color printing is therefore carried out on one sheet at a time, the printing medium only partially reducing the colors of the blanket cylinders 1 and 5.
  • the color flow is ensured by the fact that each of the two rubber cylinders 1 and 5 rotating in the direction of the arrow c and d is supplied with color again after printing from the rubber cylinder 2 and plate cylinder 6 or from the plate cylinder 10 and from the rubber cylinder 4 and thereby in turn, as a result of the color splitting, the color from the plate cylinder 6 or plate cylinder 10 to the blanket cylinder 2 or 4.
  • the invention is not restricted to the exemplary embodiment shown. You can in the same Use this way for web presses with several adjacent blanket cylinders.
  • a printing carrier web could be pressed onto the rubber cylinders 6 and 1 by means of the printing cylinders 21 and 25, for example.
  • Two print carrier webs can also be printed by means of two printing cylinders from a common blanket cylinder.
  • more than two printing cylinders can also be provided, with each of which a printing medium is printed when the machine is running.
  • production can be doubled without increasing the circumferential speeds of the blanket cylinders 1 to 5 or, if additional printing cylinders are arranged, production can be increased even further, since the machine can use two or more units per time unit more print carriers printed.
