Definitions

  • the invention relates to a printing machine for rubber-to-rubber printing horizontal web run according to the preamble of claim 1.
  • a printing unit for rubber-rubber printing with a horizontal web run shows DE 27 54 429 C2. Then there are two printing units with each a plate and a transfer cylinder one above the other arranged. It becomes horizontal between the transfer cylinders running web to be printed passed. The the axes of the The plane containing the transfer cylinder is larger Angular amount, about 30 °, inclined to the vertical. It becomes one Wrapping the transfer cylinder reached by the web. This is necessary because the transfer cylinder with clamping channels are afflicted. With an arrangement of such cylinders vertically one above the other would pass through the tension channels Pressure zone the pressure on the web and thus by the Printing unit exercised web tension and forced web run are interrupted.
  • the inclined position of the Transfer cylinder has the disadvantage of printing technology that Circumferential speed of the transfer cylinder in the Wrapping area is greater than the web speed and thereby adversely affecting the print quality Shifts between the web and transfer cylinders result.
  • the greater peripheral speed stems from the larger radius of this Cylinder opposite the one in the pressure zone Radius.
  • the invention has for its object in a generic Printing unit with a favorable web run to a good print quality achieve.
  • the Invention reduces the wrap area of the Transfer cylinder, causing the shift between web and Reduced cylinder surface and thereby the print quality is improved. From this point of view, one would be optimal omitted wrapping. But this would have the disadvantage that the train after leaving the pressure gap on the cylinder with the currently larger part of the print sticks to the subject and therefore ever fluttering to the subject. This adversely affects web tension and the print quality (dot gain, size duplex ', Circumference register error). An optimal wrapping that the printing technology concerns and a stable web run, is so at an inclination of the transfer cylinder in the specified Angular range achieved.
  • the printing unit shown in Fig. 1 contains two one above the other arranged transfer cylinders 1, 2, each one Forme cylinder 3, 4 is assigned.
  • the transfer cylinders 1, 2 work in touch with each other.
  • the angle ⁇ can in Range of 0 ° ⁇ ⁇ 10 ° can be selected.
  • the angle ⁇ in Clockwise to the vertical 6, that is, the Transfer cylinder 1 can be arranged inclined in the direction of web travel will.
  • the transfer cylinders 1, 2 are each with an endless Blanket 7 equipped.
  • Fig. 2 shows the cross section of the Transfer cylinder 1.
  • the blanket 7 is a layer on one Carrier applied in the form of a sleeve 8.
  • the rubber blanket 7 can also can be glued on without a gap, and the carrier can also be plate-shaped Can take shape.
  • FIG. 3 Here is the Transfer cylinder 9 with one running in the axial direction Provide slot 10 into which the bent legs 11, 12 one plate-shaped carrier 13 are inserted.
  • On the carrier 13 is the rubber blanket 14 glued on without a gap.
