Definitions

  • the invention relates to a sheet-fed offset printing machine according to the five-cylinder system, with a counter-pressure cylinder which takes over the sheets to be printed from a feeder, on which, seen in the transport direction of the sheets, two blanket cylinders are placed one behind the other.
  • 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.
  • page 155 of the In the same technical book a sheet-fed offset rotary machine for face and back printing, in which a sheet to be printed is passed between two blanket cylinders, one blanket cylinder carrying a gripper system, so each of these machines is fixed to a specific type of printing 038 it is also already known to produce an impression by means of the offset part of a counterpressure cylinder and with the aid of a takeover cylinder and the plate cylinder to be inked, but this is a complex printing unit.
  • the object of the invention is to make a sheet-fed offset rotary printing press of the type described at the outset without additional space requirements and in particular without a turning device optionally switchable to reverse pressure if necessary.
  • a sheet feeder 2 feeds the sheets 3 to be printed to a printing unit 1.
  • a so-called double-sized impression cylinder 4 is used, which is equipped with grippers for taking over the sheet 3.
  • Half of the circumference of the impression cylinder 4 is provided with a rubber blanket 5.
  • a further pair of cylinders 8, 9 is arranged behind the blanket cylinder 6, specifically a plate cylinder 8 and a blanket cylinder 9 which can also be adjusted to the impression cylinder 4.
  • the sheets printed in the printing unit 1 are transferred to a sheet delivery point, for example a chain system 10, through which a further transport takes place a subsequent printing unit or a sheet delivery.
  • this printing press concept it is possible, in a conventional manner, to guide the sheets 3 to be printed in a conventional manner around the impression cylinder 4 and to lead them out of the printing unit 1 again after applying a double face print.
  • a conversion of this printing unit is possible in that the blanket cylinder 6 is also equipped with a gripper system, through which a sheet 3 to be printed is taken over by the impression cylinder 4 and this sheet 3 is guided around the blanket cylinder 6, after which the impression cylinder 4 , who has made half a turn in the meantime, again takes over the sheet 3, in such a way that it now comes to rest on the rubber blanket 5.
  • the separation between the above-mentioned cylinders can be achieved by lifting a cylinder or, if the paper is sufficiently thick, it results automatically if no sheet is fed.
  • Figures 2 and 3 show the various cylinders of the printing unit 1 in different angular positions, so that the course of the guide of the sheet 3 can be seen.
  • FIGS. 4 to 6 An advantageous further development of the invention results from FIGS. 4 to 6, in which a DiLitho inking and dampening unit 12 is used behind the sheet delivery point, for example on the chain 10.
  • the opposite Printing cylinder 4 also covered with a plate 11.
  • the DiLithoplate 11 is guided past the inking and dampening unit 12, inking takes place, so that the sheet 3 created is provided with an impression when it is subsequently guided around the impression cylinder 4 to the sheet delivery.
  • the sheet initially taken over by the impression cylinder 4 can again be transferred to the first rubber cylinder 6, which is also equipped with grippers, and can be guided around the rubber cylinder once in the manner already described.
  • the mode of operation according to FIGS. 1 to 3 in the embodiment according to FIGS. 4 and 6 only one sheet is fed to the printing unit 1 over one revolution of the impression cylinder, so that there is a gap between successive sheets to be applied, the length of which in corresponds approximately to the arc length.
  • the sheet 14 is now fed to the impression cylinder 4, a back pressure is applied by the DiLitho printing plate 11 (FIG. 4). Subsequently, the sheet 14 provided with a first counterpressure is transferred to the rubber cylinder 6 and its passage past the plate cylinder 7. As a result, a counterpressure is applied in the manner already described, which here represents the second counterpressure transmitted by the DiLitho plate 7 has been. This is followed by the second transfer to the impression cylinder 4 and the passage of the sheet past the second rubber cylinder 9, to which the first printing is applied.
  • the second rubber cylinder 9 should be lifted slightly from the impression cylinder 4 if it is undesirable to have the rubber blanket 5 (FIGS. 2, 3) colored by it.
  • the plate cylinder 7 also cycles in the time in which the rubber cylinder 6 does not bend.
  • the printing unit 15 shown comprises a first blanket cylinder 18 with a plate cylinder 19 and a second blanket cylinder 20 with a plate cylinder 21 and a delivery arm 22, for example in the form of a chain.
  • the sheet 15 to be printed is fed to the printing unit 15 from a sheet feeder 16.
  • the sheets 17 are taken over by a common impression cylinder 23, which here has the same scope as the blanket cylinders 18 and 20.
  • the sheet to be printed is again taken up by the grippers of the blanket cylinder 18 to apply a counterpressure and is guided past the plate cylinder 19 , which is parked in the manner described by the blanket cylinder 18 when it does not bend.
  • the gripping of the impression cylinder 23 takes over again the sheet provided with a counterpressure, after which the impression cylinder 23 guides the sheets past the second rubber cylinder 20, by means of which a surface pressure is applied. Then the display takes place in a known manner.
  • the second rubber cylinder 20 is also lifted off the impression cylinder 23 if the latter does not pass a sheet past the rubber cylinder 20. This prevents undesired coloring of the impression cylinder 23.
