Definitions

  • the invention relates to a printing unit according to the preamble of claim 1.
  • a printing unit is known from DE-AS 28 44 418.
  • This printing unit it is possible to apply a double face print to a print carrier web or to selectively apply one face print from one of the two blanket cylinders during operation of the machine.
  • a double-sized fixed common impression cylinder is used, on which two so-called simple large rubber blanket cylinders can be adjusted together or individually.
  • Each of the blanket cylinders thus has two positions with respect to the common impression cylinder, namely an on and an off position.
  • DE-AS 1 238 929 From DE-AS 1 238 929 it is known to provide three positions for a blanket cylinder in a conventional five-cylinder printing unit which comprises a common printing cylinder and two blanket cylinders, but this is not a printing unit for a so-called "flying plate change". , d. H. With this printing unit it is not possible to alternately position the blanket cylinders on the impression cylinder during operation.
  • DE-GM 1 827 845 shows printing unit configurations (FIG. 3, FIG. 4) with which a print carrier web is either provided with a print on both sides or with a double print on one side.
  • the object of the invention is to develop a printing unit of the type specified at the outset in such a way that it can be used in a variety of ways, ie that both double-sided printing (1/1), double face printing (2/0) and an impression (1/0 below / 1/0 above) is possible, whereby duplication should be avoided when printing on both sides (1/1).
  • This object is achieved by applying the features of the characterizing part of claim 1 solved.
  • the advantage of the solution according to the invention is that minimal adjustment options are required, since the printing cylinder is fixedly positioned, one of the blanket cylinders only has to have an on and off position and the other blanket cylinder has three positions according to the respective operating modes and that three or four operating modes are possible are.
  • FIG. 1 to 10 schematically show the printing unit according to the invention in five operating modes.
  • a simply large impression cylinder 1 is locally fixed with its central axis 1 ⁇ .
  • Two blanket cylinders 2, 3 can be set on this impression cylinder 1.
  • the blanket cylinder 2 or 3 can alternately be placed on the common impression cylinder 1 (FIGS. 2, 3), so that printing on the printing medium web 6, which is guided around the impression cylinder in a known manner, is printed on one side can (1/0 above or 1/0 below).
  • the blanket cylinders 2 and 3 are each assigned plate cylinders 4, 5, which do not have to be pivoted during the individual changeover processes, but which can be lifted off the respective blanket cylinder for the plate change.
  • a further mode of operation of the printing unit shown results from the fact that, as indicated in FIG. 1, the print carrier web is carried out between the two blanket cylinders 2, 3 placed against one another and is partly continued around the impression cylinder 1.
  • the impression cylinder 1 and the blanket cylinder 2 are also placed against each other.
  • the direction of rotation of the cylinders 1, 2, 3 is indicated by arrows in the respective operating modes. It is understood that in the version shown, a reversal of the direction of rotation is required at least for the lower blanket cylinder 3, when this is turned on the impression cylinder 1 in the direction of rotation shown.
  • the individual position of the blanket cylinders 2, 3 for the operating modes mentioned is indicated by an apostrophe.
  • the position 2 ⁇ indicates the storage position of the blanket cylinder 2 from the impression cylinder 1, while the position 2 ⁇ marks the position on the impression cylinder 1.
  • the position 3 ⁇ means the position in which the blanket cylinder 3 is turned off by both the blanket cylinder 2 and the impression cylinder 1, i. H. in the case of a flying impression, a plate change can be carried out on the plate cylinder 5 in this position.
  • the position 3 ′′′ indicates the position of the blanket cylinder 3 on the impression cylinder 1. At 3 ⁇ the blanket cylinder 3 is employed on the impression cylinder 1.
  • an advantageous further development of the invention consists in that, in the printing unit according to the invention, the impression cylinder 1 can be covered with a rubber blanket 9 using a pit 8, so that a so-called re-offset on the underside of the print carrier web 6 in the perfecting mode (1/1) he follows. Furthermore, the use of a washing unit 7 attached to the impression cylinder 1 is advantageous. Perforating strips 14 can also be attached axially or circumferentially on the impression cylinder 1.
  • FIG. 5 Blanket plate cylinder pair 11, 10 z. B. above a through the center 1 ⁇ of the impression cylinder 1 horizontal plane, and possibly a further blanket-plate cylinder pair 12, 13 is arranged below this level.
  • the arrangement of the upper cylinder pair 11, 10 is thus at an angle less than 180 ° to the negative abscissa whose coordinate intersection is assumed to be the center point 1 ⁇ , measured counterclockwise.
  • the possible path guidance is indicated at 6 ⁇ .
  • Fig. 4 on the print carrier web 6 ⁇ allows double printing. The triangles each indicate on which side of the print carrier web 6 or 6 ⁇ is printed.
  • FIGS. 6 to 10 in particular for newspaper printing.
  • Fig. 6 enables 1/1 printing, it being possible to work on the face side with “flying plate change” and the counterprint is single-colored when the impression cylinder 1 is covered with a rubber blanket.
  • Fig. 7 also enables a 2/0 print with "flying plate change”.
  • Fig. 8 for the web 6 ⁇ , a 1/1 pressure and for the web 6 ⁇ a 1/0 pressure can be achieved.
  • Fig. 10 offers 2/1 and Fig. 9 a 3/0 print.
  • Fig. 7 is advantageous for local editions with a colored impression, eg. B. with underlined headings.
