Definitions

  • the invention relates to a printing unit with a short inking unit according to the preamble of claim 1.
  • CH-PS 405 365 has made a rotary printing press known for optional use as an offset or high-pressure press.
  • the plate cylinder can be optionally coated with offset printing plates or high-pressure plates. To do this, however, it is necessary to have a separate jacket available both for attaching the offset plate and for attaching the high-pressure plate. The coats of three of the cylinders involved must be exchanged for two.
  • the disadvantage of a rotary printing machine is that changing the printing ink from water-based to oil-containing printing ink or vice versa is not possible because of the surface properties of the impression cylinders. Due to their size, changing the impression cylinders in a machine is only possible under the most difficult conditions and takes a lot of time.
  • the invention has for its object to provide a printing unit with a short inking unit in a rotary printing machine for face and back printing, in which it is possible to use either "hard” or “soft” printing plates for oil-containing or water-containing printing inks on the plate cylinder.
  • a rotary printing press built for face and back printing depending on the market situation, ie on the offer and price situation of printing plates, can be equipped with either "soft" or “hard” printing plates.
  • the independence of a type of printing ink, water-based or oil-based allows a free calculation for material procurement under the most favorable market conditions.
  • a rotary printing press has two printing units 2 and 3 arranged in parallel next to one another for perfecting and reverse printing, each with a short inking unit 4; 6 on.
  • Each short inking unit 4; 6 each consists of an anilox roller 7; 8 and an inking unit 9; 11 z.
  • the anilox roller 7; 8 acts in a known manner with a plate cylinder 12; 13 and this in a known manner with an impression cylinder 14; 16 together.
  • a paper web 17 fed from below to the printing unit 1 is first deflected by a chrome-plated roller 18 and fed to a printing nip between the plate cylinder 12 and the impression cylinder 14, in which the paper web 17 is printed in straight printing mode.
  • the paper web 17 passes from below into a second pressure nip between the second by means of two chromed deflection rollers 19, 21 Plate cylinder 13 and the second impression cylinder 16, in which it is printed in reverse printing operation.
  • the impression cylinder 14; 16 each have on their circumference an axially parallel pit 22, 23, each with a device 24 for tensioning a counterpressure plate 27 and a lower blanket 28. In the pit 22; 23, three nearly pit-long tension shafts 29, 31, 32 are arranged side by side.
  • the two outer tensioning shafts 29, 32 serve to tension the undercloth 28 and each have a longitudinal groove 33, 34 for receiving an undercloth end 36, 37.
  • the middle tension shaft 31 has two opposite longitudinal grooves 38; 39 for receiving counter-pressure plate ends 41; 42 on.
  • the undercloth 28 consists of an elastic material, predominantly cork, linen or a fabric made of rubber and textiles, depending on the strength of the given compressive forces.
  • the thickness of the sub-blanket 28 is dependent on the thickness of the printing blanket 27, so that a total thickness of the sub-blanket 28 and printing blanket 27 a predetermined constant dimension z. B. does not exceed 3.3 mm.
  • the examiner 36; 37 are folded over and sewn onto the undercloth 28, so that 36; 37 a loop 40, 45 for receiving a holding wire 43; 44 results.
  • the undercloth 28 is in the area that the impression cylinder 14; 16 surrounds reinforced, so that there is a greater thickness of the undercloth than at the Untertuchenden 36; 37.
  • the material of the counter-pressure plate 27 or at least its jacket 27 depends on the requirements for the surface 26 of the counter-pressure cylinder 14; 16, either hard or soft, color or water repellent, oleo- or hydrophilic.
  • the counter pressure plate 27 can also consist of plastic or nylon fabric. So that it can be easily stretched 27 elastic cloths (z. B. linen) are riveted to both ends of the counter-pressure plate and each with a lasting rail 47; 48 provided.
  • the length of the counter pressure plate 27 is designed so that the rivet points 49; 51 do not come to rest on the pressure cylinder circumference, but in the pit 22; 28 protrude.
  • the first lasting rail 47 of the counterpressure plate 27 is in the slot 38, which initially points upward
  • the second lasting rail 48 of the counter-pressure plate 27 is inserted into the slot 39.
