Definitions

  • the invention relates to a printing unit according to the preamble of claim 1.
  • the invention further relates to a dampening unit for a printing unit of a printing press according to the preamble of patent claim 6.
  • Printing units of web-fed rotary printing presses have a plurality of printing units, each printing unit consisting of a transfer cylinder, a forme cylinder and an inking unit as well as dampening unit. Furthermore, such printing units can have impression cylinders, wherein an impression cylinder can interact with one or more transfer cylinders of different printing units.
  • printing units are also known which have no counter-pressure cylinders, wherein in such printing units without impression cylinders, the transfer cylinders of two printing couples roll on one another. On the transfer cylinder blankets are usually on the form cylinders and pressure plates are stretched, which is why the transfer cylinder as a blanket cylinder and the forme cylinder are also referred to as printing plate cylinder.
  • the inking unit of a printing unit is used to apply printing ink to the forme cylinder of the printing unit, while the dampening unit serves to apply a dampening solution to the forme cylinder of the printing unit.
  • a number of dampening units are already known from the prior art, with which dampening solution can be effectively applied to a forme cylinder.
  • dampening unit 11 has a relatively hard, chrome-coated or ceramic-coated roller 12 which receives dampening solution from a dampening solution 13.
  • two relatively soft rolls 14 and 15 are arranged between the forme cylinder 10 and the relatively hard, chrome-coated or ceramic-coated roll 12, the relatively soft roll 14 having the forme cylinder 10 and the relatively soft roll 15 having the relatively hard, chromium coated or ceramic coated roller 12 is in rolling contact.
  • Fig. 2 shows another known from the prior art dampening unit 16, which in addition to the components already described with reference to FIG. 1 has another hard, chrome-coated or ceramic-coated roller 17, with both relatively soft rolls 14 and 15th in rolling contact.
  • the second, relatively hard roller 17 then exercises as well like the first, relatively hard roller 12 in the axial direction of a traversing movement.
  • the problem is based on creating a novel printing unit and a novel dampening unit.
  • a printing unit according to claim 1.
  • two relatively soft rolls are positioned between the relatively hard, chrome-coated or ceramic-coated roll of the dampening unit and the respective forme cylinder, both of which are in rolling contact with the forme cylinder and the chromium-coated or ceramic-coated roll, so that the fountain solution accommodated by the chromium-coated or ceramic-coated roll passes over both relatively soft rolls is applied directly to the form cylinder.
  • Both relatively soft rolls thus form dampening solution application rollers.
  • the preferably an axial traversing movement performing, chrome-coated or ceramic-coated roller causes a smoothing of the fountain solution film on both fountain solution application rollers.
  • dampening unit according to the invention for a printing unit of a printing press is defined in the independent claim 6.
  • FIG 3 shows a detail of a printing unit of a printing unit of a web-fed rotary printing press in the region of a forme cylinder 100 and a dampening unit 101 in the sense of the present invention.
  • a dampening solution is applied to the forme cylinder 100.
  • the dampening unit 101 has a relatively hard, chrome-coated or ceramic-coated roller 102, which receives a dampening solution from a fountain solution supply 103.
  • a relatively hard, chrome-coated or ceramic-coated roller 102 receives a dampening solution from a fountain solution supply 103.
  • the dampening solution received by the relatively hard roller 102 is applied directly to the forme cylinder 100 via both relatively soft rollers 104 and 105, so that both relatively soft rollers 104 and 105 are designed as dampening solution application rollers.
  • the relatively hard, chrome-coated or ceramic-coated roller 102 performs a traversing motion in the axial direction, so that on both relatively soft rollers 104 and 105 by this traversing movement a smoothing of the dampening solution film on both relatively soft rollers 104 and 105 is effected.
  • the relatively hard roller 102 is thus driven in rotation via the forme cylinder 100.
  • To provide the oscillating movement in the axial direction of the relatively hard, chrome-coated or ceramic-coated roller is associated with a corresponding drive.
  • the two relatively soft rollers 104 and 105 are formed as fountain solution application rollers.
  • the dampening solution application roller 104 and, subsequently, the dampening solution application roller 105 first apply dampening solution to the forme cylinder 100.
  • This embodiment according to the invention has the advantage that the application roller 105 arranged downstream in the direction of rotation assumes a smoothing of the dampening solution film applied by the application roller 104. As a result, the quality of the dampening solution application to the forme cylinder 100 can be improved.
  • the inventive solution according to FIG. 3 allows for relatively simple dampening units with only three rollers a uniform application of a dampening solution on a forme cylinder of a printing unit of a printing unit of a web-fed rotary printing press.
