Definitions

  • the invention relates to a sheet-fed offset printing machine according to the five-cylinder system, with a counter-pressure cylinder taking over the sheets to be printed from an investor, to which, viewed in the transport direction of the sheets, two offset rubber cylinders, each working with a plate cylinder, are placed one behind the other, the counter-pressure cylinder has twice the circumference, based on the circumference of the rubber cylinders.
  • a machine of this type is known from the specialist book "Introduction to offset printing " by Wolfgang Walenski, Eggen specialist book series, page 113. With this machine, a sheet can be printed on one side with double face printing. A reversing device would be required for reverse printing.
  • page 155 of the same specialist book shows a sheet-fed offset printing machine for face and reverse printing, in which a sheet to be printed is passed between two blanket cylinders, with one blanket carrying a gripper system worked.
  • the object of the invention is to further develop a printing press of the first-mentioned type in such a way that a sheet fed into the machine can be provided with triple face printing and an additional back pressure with little additional space.
  • a major advantage of the sheet-fed offset rotary printing press is that it is also possible to apply a double perfecting and an impression if two sheets are placed on the double-sized impression cylinder during each revolution.
  • Fig. 1 shows a printing unit 1, which comprises a so-called double-sized impression cylinder 2, on which two printing plates 3 and 4 are attached.
  • An inking and dampening unit 5, 6 is arranged below the impression cylinder 2 for inking the printing plates 3, 4.
  • An offset rubber cylinder 7, to which a plate cylinder 8 is assigned, is employed on the impression cylinder. Seen in the transport direction of the sheets to be printed, a further offset rubber cylinder 9 is placed behind the blanket cylinder 7 on the impression cylinder 2, to which a plate cylinder 10 is assigned.
  • a sheet 11 coming from a conventional sheet system is picked up by a conventional gripper system (not shown in more detail), which is arranged, for example, in front of the printing plate 4, and is guided past the two rubber cylinders 7, 9, after which the sheet is passed to another printing unit or to the sheet transfer point 12 Sheet delivery, for example via a chain system, is supplied.
  • the previously colored printing image on an offset plate 3, which is mounted in mirror image with respect to a DiLitho plate 4, on the impression cylinder 2 was advantageously transferred to the rubber cylinder 7, since no sheet is fed to the printing unit 1 while the printing plate 3 runs past the blanket cylinder 7.
  • the illustration according to FIG. 2 shows that a sheet 11 can be gripped by the gripper system assigned to the pressure plate 4 and can be provided with a double front printing by the rubber cylinder 7 and with a back pressure by the printing plate 4.
  • a further imprint takes place through the rubber cylinder 9, so that the sheet at the sheet transfer point 12 is provided with a triple face print and an impression.
  • the main advantage of the printing machine comes into play according to the invention if only one sheet is applied during each revolution of the impression cylinder 2, so that a second print image is produced by one plate, for example plate 3, which in this case acts as an offset printing plate the blanket cylinder 7 can be transferred.
  • the aforementioned triple face printing (offset) plus a backprint (DiLitho) is possible without the printing unit becoming significantly more voluminous.
