Definitions

  • said machines also include the devices for fixing the plates, the ink and water supply devices, the drive motors and the necessary control and synchronization elements.
  • a machine of this type is described for example in French patent 2,512,743 and a particular detail of said machine is indicated in German patent 2,754,183.
  • Printing machines of this type have proved to be perfectly suited for offset printing of ordinary paper, cardboard and metal sheets. However, they are not directly usable for printing metal sheets (mainly aluminum) intended, according to modern techniques, for the production of cans, because such sheets have, on their side not intended for printing, very sensitive protective layers whose integrity must be ensured at all costs.
  • metal sheets mainly aluminum
  • metal sheets of this type can be printed using techniques and using offset machines thanks to a particular choice, according to which said techniques and machines involve passing the sheets "flat".
  • Such machines are quite reliable, but they lack the possibility of locating one impression on the other and speed (limit about 1 sheet per second).
  • PLANETA brand offset machines known today under the VARIANT and SUPER VARIANT types; but, of course, other machines having the characteristics mentioned above can be used; it will be noted that these machines both have two gripper bars per cylinder.
  • FIG. 1 schematically shows in section the devices for arriving the plates to be printed in the machine.
  • FIG. 2 schematically represents, seen from above, the principle of the initial positioning of the sheet to be printed on the margin table.
  • the fundamental element of the invention lies in the fact that all the surfaces with which the protective layer is likely to rub must be perfectly polished chrome surfaces; if we consider figure 1, these surfaces are essentially the surface of the margin table 1 and the surface of the arches 2; the surface of the cylinder 4 is also in polished chrome, but it will be noted that, taking into account that the plates are driven (by the clamps in particular) at a speed substantially equal to that of the cylinder, there is no real friction of the surface of the plate, comprising the protective layer on the surface of this cylinder 4.
  • a surface in polished chrome it is meant a surface having been coated with a hard chrome, the surface of which will have been made as smooth (polished) as possible by any appropriate means (chemical and / or mechanical).
  • the positioning in y is achieved by a stop 12 (rectifier plate) which can be moved longitudinally (along y) on the axis 13, which has the necessary marks; according to the invention, said stop 12 can be moved and marked, not only along the axis 13, but also along the axis 14 (x) so as to take account of any cutouts (such as 15) on the edge of the plaque.
  • a stop 12 rectifier plate
  • said stop 12 can be moved and marked, not only along the axis 13, but also along the axis 14 (x) so as to take account of any cutouts (such as 15) on the edge of the plaque.
