Definitions

  • the present invention concerns an intaglio printing machine for printing items, such as securities, on a substrate comprising at least a plate cylinder supporting at least one printing plate and inked by inking units, and an impression cylinder, both cylinders forming a printing nip through which the substrate passes during the impression operation.
  • this machine comprises a plate cylinder mounted in a stand and an impression cylinder interacting with the plate cylinder.
  • the plate cylinder has sectors which are separated by cylinder pits and on which printing plates are mounted. The plates are clamped on said sectors by gripping means arranged in said pits.
  • the impression cylinder has corresponding equal number of sectors also separated by pits and both cylinders form the printing nip.
  • the plate cylinder is inked in a direct or indirect manner, as is known in the art.
  • the web is also printed on its other side by a second intaglio printing unit similar to the first intaglio printing unit.
  • the aim of the invention is to improve the known printing machines.
  • an aim of the invention is to provide an intaglio printing machine that is efficient and simple.
  • the web-fed intaglio printing machine comprises a plate cylinder 1, carrying at least a plate 2, which is held on the cylinder 1 by known conventional means (not shown), for example clamping bars in pits formed in the cylinder 1.
  • a plate cylinder 1 carrying at least a plate 2, which is held on the cylinder 1 by known conventional means (not shown), for example clamping bars in pits formed in the cylinder 1.
  • an impression cylinder 3 which presses the web 4 against the plate cylinder in the printing nip formed between both cylinders 1 and 3.
  • the plate cylinder is inked by several inking rollers 5, in the example a direct inking system is represented, which are themselves inked by corresponding inking units (not shown) as is known in the art.
  • the principle of direct and indirect inking is disclosed in US 5,062,360 incorporated herein by reference as an example.
  • the web of substrate for example paper
  • a production paper unwinding unit 6 which also comprises a tensioning system 7 made of three rollers 8 to 10, the roller 9 being movable to control the tension in the web 4.
  • the web passes into a paper-web store 11, which, as an example, works with air under depression, i.e. a vacuum chamber.
  • This paper-web store 11 is known per se in the art and is controlled in such a way that tension in the web is maintained at a preset value.
  • the paper web is then driven by a stop-and-go draw roller 12.
  • This draw roller 12 is individually controlled intermittently for a forward a backward movement of the web 4.
  • This roller 12 can be a suction roller similar to the one disclosed in US 5,062,360 driven by an independent motor.
  • the stop-and-go roller 12 is used to adapt the motion of the paper web to the repeat length of the prints on the plate.
  • the web 4 exiting the store 11 loops around the roller 12 and then runs through the printing nip formed by cylinders 1 and 3.
  • the printed web 4 is maintained in tension by second paper-web store 13 and is guided to high energy beam drying units 14 by rollers 15.
  • the drying units 14 may be UV lamps that dry the side of the web 4 on which the printing ink has been deposited.
  • Other possible high energy beam drying units include electron beam systems, as made by the Firm Energy Science Incorporated, and excimer UV radiating systems, both known in the art.
  • rollers 16 and 17 guide the web 4 to a production paper rewind unit comprising, for example, roll 18.
  • the web is maintained under tension by a movable roller 17. Once a complete web has been printed, roll 18 is taken away for further treatment, for example other printing operations, cutting into individual sheets, quality control etc.
  • the machine according to the invention also comprises a wiping unit using wiping paper.
  • the wiping unit comprises firstly a wiping paper unwind system, with, for example a roll 20 of wiping paper 21, the wiping paper 21, in the present example having the shape of a continuous paper web, being guided to a wiping paper application cylinder 22 by rollers 23, 24. Roller 24 can be displaced in order to maintain a predetermined tension in the wiping paper 21.
  • the wiping paper 21 is then applied against the plate cylinder 1 by a wiping paper application cylinder 22.
  • Said cylinder 22 is moved towards and away from the plate cylinder 1 by a moving system schematically represented by a rotatable bar 25 in the figure.
  • the wiping paper 21 is applied (contrary to the direction of rotation of the plate cylinder 1) after the inking units but before the printing nip, and is used to wipe the ink present outside the cuts of the plate 2 carried by the plate cylinder 1 to improve the quality and precision of the inking.
  • the application of the wiping paper 21 is adapted to the size of the plates 2 and to the position of the engravings in the plates 2 in order to minimize consumption of wiping paper 21.
  • the wiping paper 21, once used is brought to a wiping paper rewind system 26, comprising for example a rewind roll, by rollers 27, 28. Roller 28 may be displaced in order to maintain a predetermined tension in the wiping paper 21 web.
