Definitions

  • the invention relates to a transmission form for a transfer cylinder of a printing press according to the preamble of claim 1.
  • a printing unit of a printing machine in addition to a forme cylinder and a transfer cylinder further comprises an inking unit and preferably a dampening unit.
  • On the forme cylinder is at least one printing plate and on the transfer cylinder is arranged at least one transfer mold.
  • Form cylinders are also referred to as a plate cylinder and transfer cylinder as a rubber cylinder.
  • a blanket plate has a plate-shaped carrier.
  • a color transfer blanket is applied on a first side of the plate-shaped carrier.
  • a film is applied, wherein on the film an elevator height of the transfer form can be determined on a transfer cylinder.
  • the plate-shaped carrier of the blanket plate may be made of a metallic material or of a plastic. Blankets are also referred to as metal blankets.
  • the blanket and the film are applied to the plate-shaped support such that one of the film in the region of the second side covered surface of the plate-shaped support corresponds to the surface which covers the blanket on the first side of the plate-shaped carrier.
  • the present invention is based on the problem to provide a novel transfer form for a transfer cylinder of a printing press with improved printing properties.
  • the film is applied to the second side of the plate-like carrier such that a surface of the carrier covered by the film on the second side is smaller than a surface of the carrier covered by the blanket on the first side.
  • the foil is proposed to apply the foil to the plate-shaped carrier in such a way that the foil on the second side of the foil covered on the second side is smaller than that on the first side blanket covered by the blanket is the plate-like carrier. This can improve the print quality.
  • the coverage of the plate-like support through the film is smaller than the overlap of the plate-like support by the blanket.
  • the plate-like carrier has a tensioning the transmission form serving leading end and trailing end, wherein the leading or trailing edge of the film from the bending radius of the leading end and / or trailing end have a distance between 4 mm and 10 mm, and wherein in the middle between the leading and the trailing end of a section with a width between 8 mm and 16 mm is not covered by foil.
  • FIGS. 2 and 3 Before referring to below FIGS. 2 and 3 a transmission form according to the invention will be described in detail, is previously with reference to Fig. 1 a known from the prior art transmission form described.
  • Fig. 1 shows very schematically a known from the prior art, designed as a blanket plate 10 transmission form, the blanket plate 10 having a plate-like carrier 11 identifies.
  • a color blanket 12 serving for ink transfer is applied.
  • a film 13 is applied, via which an elevator height of the blanket plate 10 is set on a transfer cylinder.
  • the plate-like carrier has a tensioning of the blanket plate 10 serving leading end 14 and trailing end 15.
  • the blanket plate 10 can be stretched in a clamping channel of a transfer cylinder.
  • the leading end 14 and trailing end 15 is angled relative to the plate-like carrier 11, namely to form so-called bending radii.
  • FIGS. 2 and 3 show a preferred embodiment of an inventive, designed as a blanket plate 16 transmission form.
  • the blanket plate 16 of the Fig. 1 and 2 in turn has a plate-like support 17, wherein on a first side of the plate-like support 17 in turn a blanket 18 and on one of the first side opposite second side in turn a film 19 is applied.
  • the film 19 is applied to the second side of the plate-like carrier 17 such that a surface of the carrier 17 covered by the film 19 on the second side is smaller than a surface covered by the blanket 18 on the first side of the carrier 17.
  • Fig. 2 In the circumferential direction of the blanket plate 16 (arrow 21), however, is the overlap of the plate-like in the circumferential direction of the blanket plate 16 (arrow 20) covering the plate-like carrier 17 through the film 19 of the overlap Carrier 17 through the film 19 smaller than the overlap of the plate-like carrier 17 by the blanket 18th
  • the plate-like support 17 of the blanket plate 16 in turn has a leading end 22 and a trailing end 23.
  • the blanket plate 16 of the invention can be clamped to a transfer cylinder, for this purpose leading end 22 and trailing end 23 engage in a clamping channel.
  • the distance of the film 19 from the leading end 23 and trailing end 23 is greater than the distance of the blanket 18 from the leading end 23 and trailing end of the 23rd
  • leading end 22 and the trailing end 23 opposite edges of the film 19 have a greater distance from a bending radius of the leading end 22 and the trailing end 23 than corresponding edges of the blanket 18th
  • a distance X1 between the bending radius of the leading end 22 and trailing end 23 and an edge of the film 19 opposite the respective bending radius is between 1 mm and 10 mm.
  • the pressure of the blanket can be reduced against the forme cylinder in the region of the clamping channel, so that Mittiken printing plate edges, which roll over the blanket plate 16 in these areas, can be prevented.
  • the film applied to the second end of the plate-like carrier 17 has a thickness X3 between 0.04 mm and 0.6 mm.
