Definitions

  • the invention relates to a printing machine for rubber-rubber printing with a horizontal web run according to the preamble of claim 1.
  • DE 27 54 429 C2 shows a printing unit for rubber-rubber printing with a horizontal web run. Then two printing units, each with a plate and a transfer cylinder, are arranged one above the other. The horizontally running web to be printed is passed between the transfer cylinder. The plane containing the axes of the transfer cylinders is inclined to the vertical by a larger angular amount, approximately 30 °. As a result, the web is wrapped around the transfer cylinder. This is necessary because the transfer cylinders have clamping channels. In the case of an arrangement of such cylinders vertically one above the other, the pressure on the web and thus the web tension and positive web travel exerted by the printing unit would be interrupted when the tensioning channels pass through the pressure zone.
  • the inclination of the transfer cylinders shown in the cited publication has the disadvantage in terms of printing technology that the peripheral speed of the transfer cylinders in the looping area is greater than the web speed and this results in displacements between the web and transfer cylinders which adversely affect the print quality.
  • the greater peripheral speed stems from the larger radius of these cylinders compared to the radius that arises in the pressure zone.
  • the invention has for its object to achieve good print quality in a generic printing unit with a favorable web run.
  • the invention reduces the wrap-around area of the transfer cylinders, as a result of which the displacement between web and cylinder surface is reduced and the print quality is thereby improved. From this point of view, a completely omitted loop would be optimal. However, this would have the disadvantage that after leaving the printing nip, the web sticks to the cylinder with the currently larger pressure component of the subject and flaps depending on the subject. This has an adverse effect on the web tension and the print quality (dot gain, circumferential duplex ', circumferential register error). Optimal wrapping, which meets the printing requirements and a stable web run, is therefore achieved with an inclination of the transfer cylinders in the specified angular range.
  • the printing unit shown in Fig. 1 contains two transfer cylinders 1, 2 arranged one above the other, each of which a forme cylinder 3, 4 is assigned.
  • the transfer cylinders 1, 2 work in contact with each other.
  • the angle ⁇ can be selected in the range from 0 ° to 10 °.
  • the angle ⁇ can also be clockwise to the vertical 6, that is, the transfer cylinder 1 can be arranged inclined in the web running direction.
  • the transfer cylinders 1, 2 are each equipped with an endless blanket 7.
  • Fig. 2 shows the cross section of the transfer cylinder 1.
  • the rubber blanket 7 is applied as a layer on a support in the form of a sleeve 8.
  • the rubber blanket 7 can also be glued on without a gap, and the carrier can also have a plate-like shape.
  • FIG. 3 the transfer cylinder 9 is provided with a slot 10 running in the axial direction, into which the bent legs 11, 12 of a plate-shaped carrier 13 are inserted.
  • the rubber blanket 14 is glued onto the carrier 13 without a gap.
  • a particularly advantageous development of the invention consists in the blanket sleeves 7, 8 and 13, 14 in the printing unit 1, 3 shown in FIG. 1; 2, 4 with cylinders 1, 2 left in the printing unit, to be changed from the cylinder front side, i.e. through the printing unit side wall with cylinders suspended on one side (see e.g. DE-PS 35 43 704, Figure 6).
