Definitions

  • the invention relates to a multi-color rotary printing machine for duplex printing simultaneous with the reel or sheet, in particular for printing the security background of fiduciary papers and in particular banknotes, according to the preamble of claim 1, as well as a method for putting this machine into action.
  • the paper passes between the two blanket cylinders of the second pair which are pressed against each other and transfer the image of one respectively from the other inked letterpress plate to one, respectively the other side of the paper.
  • the color selector cylinders are in contact with an elastic surface of the collecting cylinder, they can be made of hard material which makes it possible to cut out very fine raised areas, therefore very fine colored parts, for example in the form of lines or dots.
  • the purpose of this invention is to create a single machine for simultaneous duplex printing having the possibility of exploiting the two methods described above and called below "Orlof” process and offset process, as well as also the two processes at the same time to carry out an "Orlof” printing on one side and an offset printing on the other side of the paper, ensuring the passage from one process to the other in the simplest way.
  • the machine shown relates to a sheet printing machine and comprises a sheet-shaped paper input device 1 provided with a margin cylinder 22, cylinders of transfer 23 fitted with pliers, and optionally with a numbering device 24 for the edges of the sheets and a device for dedusting and eliminating static electricity 25 installed on both sides of the paper 1.
  • the sheets are transferred to a cylinder blanket holder 17 provided with the clamps and forming with another blanket cylinder 7 of the same diameter a first pair of blanket cylinders which are pressurized and between which the sheets are printed simultaneously on both sides.
  • the cylinders rotate in the direction indicated by the arrows.
  • the sheets are transported by a transfer cylinder 26 and a chain clamp system 27 on output stacks or, if necessary, to a machine to complete the printing.
  • the paper 1 can be printed either according to the "Orlof” - “Orlof” process (figure 1), or according to the offset-offset process (figure 2), or according to the offset- "Orlof” process, the offset image can be on the front side and the "Orlof” image on the back side ( Figure 3) or vice versa ( Figure 4).
  • the paper 1 passes between the two blanket cylinders 7, 17 pressurized. Each of these blanket cylinders 7,17 is associated with a blanket cylinder 2, 12 of a second pair.
  • the machine is composed of two symmetrical halves, for this reason below or only half will be described in detail, namely the right half.
  • the blanket cylinder 2 is spaced from the corresponding blanket cylinder 7 and cooperates in the example illustrated with four color selector cylinders 8 having reliefs 8a cut according to the contour of the areas to be printed in the respective color, they are inked in said color, each one, by means of an inking device 9 with double inkwell.
  • These selector cylinders 8 with their reliefs 8a are preferably made of hard material which does not risk being deformed even if the relief is very fine, thus making it possible to obtain a safety background composed of very fine lines.
  • the areas of the four colors are transferred to the blanket cylinder 2 which functions as a collecting cylinder on which they are joined and by which they are transferred to a plate cylinder 5 carrying a letterpress printing plate 5a in contact with said cylinder collector; this plate 5a represents the complete drawing to be printed in four colors.
  • the complete image inked in the different colors is in turn transferred via an intermediate rubber cylinder 6 to the blanket cylinder 7 of the same diameter as the blanket cylinder 2, and which cooperates with the blanket cylinder 17 of the other half of the machine to apply the printing of the complete image on the corresponding side of the paper.
  • the intermediate cylinder 6 is necessary because of the direction of rotation of the blanket cylinder 7.
  • the machine furthermore comprises a first image transmission cylinder 3 and a second image transmission cylinder 4 which transfer the same image of the colored areas of the blanket cylinder 2 in perfect register on the typographic plate cylinder 5, thus making it possible to reinforce the inking of the typographic plate 5a in the desired colors and therefore to better cover these areas with the desired ink. Indeed, given the direction of rotation of the blanket cylinder 2, part of the ink is transferred by the cylinders 3 and 4 onto the typographic plate 5a of the plate cylinder 5 while the rest of the ink is transferred in perfect register directly on the plate cylinder 5.
  • the arrangement of the cylinders concerned to obtain this double inking is known (DE-A-3 109 964), the second inking being offset by the length of the periphery of the cylinder plate 5 or in the example considered of a third of the periphery of the blanket cylinder 2 because the latter has a diameter three times larger than the diameter of the cylinder 5 and carries three blankets.
  • the arrangement of cylinders 2, 3, 4 and 5 is such that the sum of the arc lengths on the peripheries of cylinders 3, 4 and 5 between the respective contact points - seen in the direction of rotation of these cylinders-must be equal to the length of the arc on the periphery of cylinder 2 between the points of contact of the latter with cylinders 3 and 5 plus 1/3 of the periphery of this cylinder 2.
  • the printing according to the "Orlof" process is completed by a wet offset pressure also carried out when the paper passes between the blanket rollers 7, 17, and which is used in particular to print a main monochrome drawing of paper. value.
  • the wet offset unit comprises a hollow plate cylinder 10 provided with an inking device 11 and a wetting device 11 a, known per se, this hollow plate cylinder 10 cooperating with the door cylinder -white blankets 7 which transfers the image to the paper. Therefore, in the case under consideration, a complete printing is obtained in a single pass, for example the security background in four colors by a printing according to the "Orlof" process and the main monochrome drawing by a wet offset printing.
  • the ratio of the diameters of the cylinders 3, 13, 4, 14, 5, 15, 6, 16, 8, 18, 10, 20 on the one hand and of the cylinders 2, 12, 7, 17 of on the other hand is 1: 3; the periphery of the cylinders 2, 12, 7 and 17 therefore corresponding to three sheets of paper, these cylinders each carry three blankets.
  • the printing plates 8b and 18b are offset plates, in particular typographic plates as used in dry offset, and represent partial drawings which are inked, as in the previous case, by inking devices 9 and 19.
  • These partial drawings in different colors are combined on the blanket cylinder 2 respectively 12 operating here as an offset blanket cylinder, therefore as a collecting cylinder for the partial drawings making up the multicolored image.
  • the multicolored image on the cylinder 2 respectively 12 is transferred via the cylinder 7 respectively 17 on the paper.
  • Such an eccentric assembly is well known for adjusting the pressure setting and for separating two cylinders if the machine is not in operation, the assembly being such that by turning the eccentric the axis of the cylinder moves. Therefore, for this spacing, the invention uses means which are already known in existing machines. When two cubic sizes are separated, the distance which is separated is very minimal, only one or a few mm, the distance illustrated in the figures being greatly exaggerated.
  • the inking devices 9 and 19 are generally mounted on mobile carriages.
  • the machine also allows "offset” - "Orlof” printing, as shown in Figure 3.
  • the right side of the machine produces the "Orlof" impression by means of the color selector cylinders 8, 8a and the plate cylinder 5 carrying a typographic plate 5a, inked by the blanket cylinder 2 which functions as a collecting cylinder in turn inked by the selector cylinders 8, 8a and separated from the blanket cylinder 7.
  • the left side of the machine produces offset printing by means of the plate cylinders 18 provided with offset plates 18b which ink the blanket cylinder 12 in contact with the blanket cylinder 17.
  • the cylinders 13,14 , 15 and 16, out of function, are separated from the cylinders 12 and 17.
  • a fourth operating mode according to FIG. 4, the two halves of the machine are exchanged and it is the left side which prints the "Orlof" image by means of the selector cylinders 18, 18a and the plate cylinder 15 , and the right side which prints the offset image by means of the offset plate cylinders 8, 8b.
  • each side of the paper also receives a wet offset printing by the hollow plate cylinder 10 respectively 20.
  • the possibility of choosing the sides in the case of mixed simultaneous printing is essential if the paper printed in the machine described passes yet another printing unit so that at least one of the sides of the paper receives a second printing, for example intaglio printing to complete the main drawing, or, if the wet offset printing unit 10, 11, 11a, respectively 20, 21, 21a is not used, to create the main drawing.
  • a second printing for example intaglio printing to complete the main drawing, or, if the wet offset printing unit 10, 11, 11a, respectively 20, 21, 21a is not used, to create the main drawing.
  • the plate cylinder 5, 15 is located contact with blanket cylinder 7, 17 while the intermediate cylinder 6, 16 is in contact with the blanket cylinder 2, 12.
  • Figures 5 and 6 show simplified variants for the simple inking of the typographic plate 5a of the cylinder 5, in which the image transmission cylinders 3 and 4 are omitted.
  • the plate cylinder 5 is in contact with the blanket cylinder 2 and the intermediate cylinder 6 transmits the image on the blanket cylinder 7, while, according to Figure 6, it is the cylinder intermediate 6 ', which is in contact with the blanket cylinder 2 and which transfers the ink to the letter plate 5'a of the plate cylinder 5', in turn in contact with the blanket cylinder 7.
  • the same inking mode can naturally be used in the other half of the machine.
  • wet offset unit 10, 11, 11a respectively 20, 21, 21a mentioned in the context of the invention, but this system makes it possible, as mentioned, to obtain a complete impression on one side of a value paper in one pass. If space permits, two or more wet offset printing units can also be provided on at least one side.
  • the color selector cylinders 8, 8a and 18, 18a intended to ink the blanket cylinder 2.12 with a collecting function can be replaced by sectioned plates functioning as color selector plates applied to a cylinder. In this case, it is therefore sufficient to change from one printing process to another to change only the plates on the cylinders 8, 18 in contact with the corresponding blanket cylinder, the bodies of the cylinders themselves not being changed.
  • the machine described can be used without other as a web printing machine by simply replacing the means of transporting the sheets by means of transporting a strip of paper which passes between the blanket cylinders 7, 17.
  • At least one of the printing units comprising a plate cylinder 8 or / and 18 and an inking device 9 or / and 19 on one or / and the other side of the machine can also be a wet offset unit, the respective plate cylinder or cylinders being provided with a wet offset plate.
  • the wet offset printing unit 10, 11, 11 a or / and 20, 21, 21a can be replaced by a dry offset printing unit.
