Definitions

  • the invention relates to a printing unit for a sheet-fed offset rotary printing press with at least one plate cylinder, to which an inking unit and a dampening unit are assigned, at least one blanket cylinder and an impression cylinder, via whose printing cylinder an impression can be applied to the sheet.
  • Known printing units of this type cf. Walenski Introduction to offset printing » pages 143, 148 and 155, are designed so that the sheet runs between two rubber cylinders, each of which is assigned a plate cylinder with an inking unit and a dampening unit, and is thus printed on both sides.
  • Such a configuration requires a special printing unit for face and reverse printing.
  • the subsequent expansion of an already designed straight printing unit on this basis fails due to the lack of space for the plate cylinder.
  • due to their higher purchase price such printing units are calculated too expensive for a print shop if only occasional perfecting is to be carried out.
  • the invention has for its object to design a printing unit of the type mentioned with little effort and largely maintaining its structure so that if necessary a perfecting can be carried out.
  • Sheet-fed offset printing presses have already become known, cf. Walenski «Introduction to offset printing», pages 147, 151 and 154, or CH-A-280 502, in which the sheets are turned between two printing units.
  • a downstream printing unit after the turning device has been switched on, produces a counter pressure instead of a further perfect printing.
  • Such a reversing device can generally be retrofitted, but it has the disadvantage that setting up for perfecting takes more time than setting up for one-sided printing.
  • additional measures such as the use of blowing or suction air, must be taken to avoid increased waste, since the sheets tend to smear when turning.
  • not only a pressure-free strip along the front, but also a corresponding strip along the back must be kept free on each sheet, on which the grippers can engage. Compared to single-sided multi-color printing, the format of the sheet is therefore used less well.
  • the 1 comprises two plate cylinders 1, 2, each of which an inking unit 3, 4 and a dampening unit 5, 6 are assigned. Each of the two plate cylinders 1, 2 interacts with a rubber cylinder 7, 8. Furthermore, an impression cylinder 9 is provided, which, cf. Fig.2, gripper 10 carries.
  • the diameter of the printing cylinder 9 is, as FIG. 3 can be seen by the amount "2a” is smaller than the diameter of the fixed to the impression cylinder 9 measuring or bearer ring 11.
  • the dimension "a” e n t-speak at least the thickness a planographic printing plate 12 which can be clamped onto the impression cylinder 9.
  • Two pairs of clamping strips 13, 14, 15, 16 are used to clamp the planographic printing plate 12 on the impression cylinder 9, between which the two ends of the planographic printing plate 12 are clamped by means of screws 17, 18.
  • the pair of tensioning strips 13, 14 can be suspended with a web 19 in a groove 20 in the cylinder jacket 21.
  • the pair of tensioning strips 15, 16 can be suspended with a web 22 in a groove 23 of a tensioning shaft 24, which is mounted between the side walls of the pressure cylinder 9.
  • the planographic printing plate 12 can then be clamped by rotating the tensioning shaft 24 in the direction of arrow b.
  • the grippers 10 are mounted together with their actuating shaft 25 and a gripper impact strip 26 between two plates 27 which are fastened on a pivot shaft 28 mounted on the side walls of the impression cylinder 9.
  • the pivot shaft 28 can be rotated, for example, by means of a worm drive, not shown, in the direction of arrow c, so that the gripper bar 26 enables the insertion of the pair of clamping bars 13, 14 into the pit of the pressure cylinder 9.
  • an inking unit 29 is provided which can be adjusted to the impression cylinder 9. Furthermore, a dampening unit 30 can be set on the impression cylinder 9.
  • the additional design effort and space required to carry out an additional counterpressure is low, since only an inking unit, possibly a dampening unit and clamping means in the impression cylinder 9 are additionally required.
  • the printing unit is therefore particularly suitable for printers who only occasionally have to make perfect and reverse prints. If the printing unit is used only for straight printing, that is, the inking unit 29 and dampening unit 30 are switched off from the impression cylinder 9, there is the further advantage that either an elastic elevator, for example a rubber blanket, or a rigid elevator, for example a metal plate, is optionally present on the impression cylinder 9. can be clamped, depending on the type of printing cylinder surface the customer wishes to use for the respective order.
  • the sheets are transferred from the grippers 10 of the impression cylinder 9 to the grippers of a transport chain system 31.
  • This system conveys the sheets to a downstream printing unit, which can be designed like the printing unit described above, or to a sheet delivery.
