Definitions

  • the invention relates to a printing press a ink and a dampening system, which by means of Ink and dampening rollers with a printing form cooperate, and with a control device for Relocation of the dampening roller in a plant or Distance to the printing form (DE 31 46 223 C2).
  • the pressure plate against environmental influences e.g. Can cause corrosion to protect.
  • a so-called gumming agent is used for this, that e.g. Contains gum arabic.
  • the gumming agent is transferred from the printer to the printing plate applied, which forms a protective layer, when resuming printing from Remove the printer. The previous procedure is time consuming and - in terms of removal the protective layer due to the chemical to be used Medium - if necessary only in connection with Protective measures feasible.
  • the invention is therefore based on the object to specify a printing press of the type mentioned at the outset, with the rational and harmless to health Way gumming the printing form is feasible. Furthermore, it should also be simple removing the gum can be done can.
  • the dampening system of offset printing machines to be provided with a distribution cylinder which is machine-driven and with the dampening roller cooperates.
  • the dampening roller receives an additional drive torque via the distribution cylinder, so that there is no slip to the printing form -
  • the printing form is preferably the already mentioned printing plate on a plate cylinder the offset printing machine is clamped.
  • distribution cylinder is preferably used for transmission of the rubberizing agent to the dampening roller used by this as a link between the Rubber dipping roller and the dampening roller forms.
  • the dampening roller takes its washing process Position to the plate cylinder so that when Wash off the clamped on the plate cylinder Pressure plate the washing liquid also to the dampening roller arrives, so that existing gum residues also be removed. Especially there is a separation in this washing process Dampening solution delivery device, that is, the washing liquid does not get into the dampening solution reservoir Printing press.
  • This washing process can also for cleaning a part of the dampening system Distribution cylinder this in its contact position Moist application roller are shifted so that both the printing form and the dampening roller as well Distribution cylinder from the rubber coating or from rubber residues be freed.
  • Fig. 1 shows a part of the rollers of an offset printing machine in a schematic representation. essential Components of the offset printing machine, e.g. the inking unit, the blanket cylinder and the impression cylinder are not shown for the sake of simplicity.
  • 1 shows a dampening unit 1 with a dampening agent delivery device 2, one with dampening solution 3 Filled fountain solution 4 has.
  • One with a drive provided dampening solution dipping roller 5 dives with a Section of its outer surface in the dampening solution 3.
  • the dampening unit 1 also has a metering roller 6 on that via a gear transmission with the dampening solution immersion roller 5 is coupled. - With the metering roller 6 acts a dampening roller 7 together, in the position comes into contact with a printing form 8.
  • the Printing form 8 is preferably as on a plate cylinder 9 clamped pressure plate (not shown) educated.
  • a driven distribution cylinder 10 is also provided, which interacts with the dampening roller 7.
  • the dampening solution 3 from the dampening solution immersion roller 5 transferred to the metering roller 6 as a thin wet film and arrives from there via the dampening roller 7 Printing form 8.
  • the dampening solution is dosed on the one hand by varying the slip between the Metering roller 6 and the dampening roller 7.
  • the distribution cylinder 10 has the task of dampening solution particles (in particular Water) in the on the dampening roller Color of an inking unit (not shown) to incorporate. This color comes from the printing form 8 and optionally from an intermediate roller, which in Position to an inking roller and the dampening roller 7 stands. In this respect, the intermediate roller forms a link between the dampening unit 1 and the inking unit (not shown).
  • a gumming device 11 provided a rubberizing plunger 12, which in a with Gummed liquid 13 immersed tub 14.
  • the roller assembly takes a position a in which on the printing form 8 a rubber coating is applied. From the driven rubber coating roller 12 promoted rubber coating 13 is on the distribution cylinder 10 and from there to the Damp applicator roller / transfer and then comes on the pressure plate.
  • the dampening unit 1 belong Rolls, namely the dampening roller 7 and the distribution cylinder 10 according to the invention for another, another purpose, namely the gumming of Printing form 8, used. It is therefore possible to use rubber coating to be applied automatically.
  • the gum forms a protective layer that prevents corrosion etc. of the Pressure plate prevented.
  • the teaching according to the invention therefore allows this automatic gumming of the printing form 8 as well as the Cleaning of printing form 8 and for gumming used components of the offset printing machine.
  • the teaching of the invention includes, of course also the case that the rubber plunging roller 12th not with the interposition of the distribution cylinder 10 the dampening roller 7 acts, but a direct one Takes up contact with the latter.
