Definitions

  • the invention relates to a high-performance printing method and device.
  • each portion having a determined length known as ply format, the ply being stressed continuously by a calling speed and being printed by successive cycles, each cycle comprising a printing phase during which the web is printed by imposing on the printed portion a running speed called printing speed which is greater than the calling speed and a following phase during which acts on the speed of the sheet to reposition the sheet for the next cycle.
  • the present invention proposes a technique which makes it possible to reposition the tablecloth while avoiding any stopping and any backtracking of the tablecloth while allowing to obtain exactly connected tablecloth formats.
  • a rotary printing transfer cylinder is used to which the printing is transferred from a cylinder and the speed of call is adjusted so that during the duration of two rotations of said cylinder, the length of the web called be equal to two tablecloth formats.
  • a printing transfer cylinder is either a blanket used in wet or dry offset, or a cylinder with typographic characters, or a cylinder engraved in rotogravure.
  • two printing contacts are made simultaneously between the web and the print transfer cylinder during the printing phase by adjusting the duration of the contacts as a function of the web format.
  • a speed is applied to the web upstream of the printing which is exerted in the same direction as the calling speed but which is lower than the calling speed.
  • the devices include a plate cylinder 1 in printing contact with a blanket cylinder 2 and means 3 to 9 which define a web path passing in the immediate vicinity of cylinder 2.
  • These means comprise two rotary pressers 3,4 movable simultaneously between a retracting position and a service position (that shown in the figures) where they bring the ply P into contact with the cylinder 2 in two distinct places A and B which are separated on the cylinder by a length equal to the developed of the plate cylinder and which are separated on the sheet by a length of sheet equal to three formats of sheet.
  • the means for producing this length of ply between the contact zones A and B consist for example of one or more rollers 5 which force the ply to form a loop between these contacts.
  • the tablecloth is permanently called in the direction of travel by a rotary call means 9, the speed of which is regulated by a pinion said to be of format, for example a tractor with pins arranged downstream of the cylinder 2 and which will be called ci - after debtor.
  • air vacuum cylinders 6,7 are disposed respectively upstream and downstream of the cylinder 2 as will be explained below.
  • the duration of a cycle is defined as the time required for two complete rotations of the plate cylinder 1.
  • the duration of the printing phase is that necessary for the printing of the printing transfer cylinder 2 by the plate of the plate cylinder 1: this duration of the printing phase is at most equal to one rotation of the cylinder -plate 1, it is therefore at most equal to the duration of a half-cycle and there is therefore at least the duration of a half-cycle to absorb the loop which will have formed during the printing phase between the cylinder print transfer 2 and tractor 9.
  • the length of a printing plate is always at least slightly less than the projection of the plate cylinder since a fraction of this projection corresponds to the slot for holding the plate on the cylinder.
  • the maximum print size is 12 inches but it can be much smaller and, for example, 8 inches.
  • the printing transfer cylinder normally has a developed which is twice or three times the developed of the plate cylinder.
  • the development of the print transfer cylinder is therefore 39 inches ( Figure 1) or 26 inches ( Figure 2).
  • the pressers have even developed as the plate cylinder, for example 13 inches.
  • the device shown in Figure 1 operates as follows.
  • This second third allows the re-inking of the impression transfer cylinder, after which a new cycle can be accomplished, the parts of the blanket upstream of the pressers 3 and 4 being suitably inked.
  • this loop contains at the end of a printing phase two printed tablecloth formats separated by an unprinted tablecloth format.
  • the pressers release the web during the rest of the cycle.
  • the air vacuum cylinder 6 rotating at slow speed in the direction of the movement of the sheet will tighten the sheet on the cylinder 8, the spiked debtor 9 will resume the movement of the sheet at call speed waiting for a new pressurization of cylinders 3 and 4.
  • the air vacuum cylinder rotates at a speed 3 to 4 times lower than the speed of the debtor 9.
  • the sheet is again tensioned, it slides on the cylinder 6, the air depression having only the effect a regulated tension of the sheet.
  • the length of the ribbon loop between the two print contacts is normally three dimensions of ribbon, but may be greater.
  • a device in accordance with the invention typically makes it possible to produce 24,000 prints per hour for a web movement which corresponds to only half, that is to say 12,000 cycles per hour.
  • the cylinder 7 also with air depression rotates in the direction of the web flow at a speed slightly higher than the printing speed. Its suction effect is lower by half of the cylinder 6.
  • the cylinder 7 is useful for peeling off the blanket sheet in the printing phase and for maintaining a suitable tension in the last phase of the cycle.
  • the movement of putting in and out of pressure of the cylinders 3 and 4 is carried out by a cam synchronized with the movement of the blanket.
  • the cam is adjustable in elongation to adjust the pressurization or pressure depending on the desired print format.
  • the printing cylinder is such that its developed corresponds only to twice the developed of the plate cylinder 1.
  • the two pressers 3 and 4 are therefore diametrically opposite so that the contact points are separated of the value of a print format assuming that this format corresponds to the development of the plate cylinder.
  • Pressers 3 and 4 of 13 are built with a flat part of 1".
  • This neutral part of 1 is used to provide the time necessary for the pressurization of the two cylinders 3 and 4.
  • This flat part of 1 is always synchronized with the pressurization at the start of the cycle. As a result, the pressurization is clear, the sheet of paper is taken according to a rigorous generator.
  • the paper and print size is assumed to be 12 ".
  • the printing phase will be 12/13 of the rotation of the cylinder 1 plate holder after which the pressers 3 and 4 will be released.
  • the debtor cylinder 9 will call the 12/13 of 12 ", that is: 11" 076,922 of paper.
  • a loop of paper will form around the cylinder 8 of a little less than 1 ". This loop will be absorbed during the next phase which corresponds to 1/13 of a revolution of the printing cylinder plus one full revolution of this cylinder, or in total 14/13.
  • the cylinder is adjusted retarder 6 at a speed lower than the call speed of the debtor 9.
  • the cylinder 7 is intended to maintain the tension of the web during the printing phase and during the paper take-up phase. Its speed is slightly higher than the printing speed to ensure proper tension when changing gears.
  • the printing phase will correspond to 12/13 of a second and the format recovery phase to 14/13 of a second , in the case of a 12 "format setting.
  • the printing phase will be 8/13 of a turn of the plate cylinder 1
  • the debtor 9 will have called 8/13 of its 8" format, that is: 4 "923
  • the loop formed around cylinder 8 will be just over 3 ".
  • the length remaining in the cycle will be 18/13 of a revolution of the plate cylinder 1 expressed in time in the example of 1 second for a revolution of cylinder 1: we will then have the values of 8/13 of a second for the phase of printing and 18/13 of a second for the catch-up phase.
  • the repositioning of the paper corresponds to the moment when the tablecloth tightens on the cylinder 8.
  • the tablecloth takes up the call speed of the debtor 9 and allows a precise restart of the printing phase.
  • the actuation of the pressers 3 and 4 takes place by means of an amplitude adjustment cam, in a manner known per se.
