Definitions

  • the invention relates to a device for aligning a blanket on a blanket or forme cylinder for recessed inline coating in a rotary printing press according to the preamble of patent claim 1.
  • One of the best-known designs for tensioning a rubber blanket provides for both ends of the same to be provided with clamping devices which engage in grooves in two tensioning spindles.
  • the blanket is tensioned by turning the tensioning spindles via worm gear using a torque wrench.
  • the G ummituchenden with the clamping devices is done by screwing the rubber blanket between terminal strips.
  • the tensioning shafts are lemm afford the K held by molding compound in the grooves.
  • an offset rubber blanket is preferably required for the direct painting method, in which the top layer of rubber blanket has been removed from the areas that are not to be painted.
  • a cloth prepared in this way can also be used for the indirect painting method if a plate cylinder is rolled over the entire surface with water-based dispersion paint.
  • the situation is the non-prepared to be painted, that is to be cut out parts of the rubber blanket used for varnishing so that a color imitation of the stop supplying lines F is transmitted arbform applied by the material to be printed, by print on the dry coating blanket.
  • Cutting out the corresponding point in the machine is time-consuming and extends the set-up time. Unclamping the rubber blanket after it has received the ink gossip in order to cut it out in parallel with the complete setup of the color forms of the inline printing press is still time-consuming because it has to be re-clamped.
  • the object of the invention is to provide a device in which, when a rubber blanket prepared in this way is clamped in, the complex setup process is dispensed with and at the same time there is the possibility of readjusting the rubber blanket in the axial and circumferential directions.
  • the alignment aid created makes it much easier to align a rubber blanket for recessed inline painting on a rubber blanket or forme cylinder without circumferential and side registers.
  • the system still allows alignment.
  • This enables corrections both in the circumferential direction and in the axial direction, e.g. if the rubber blanket has to be retightened after a large number of varnishes or has to be readjusted to compensate for inaccuracies in fit, in order to produce the exact position of the areas to be varnished in relation to the color form.
  • each tensioning spindle 3, 4 carries a clamping device 5, 6 for the rubber blanket ends 7, 8 of the rubber blanket 26.
  • the tensioning of the rubber blanket 26 is carried out by turning the tensioning spindles 3 and 4 via a worm drive, e.g. by rotating the clamping spindle 3 via the worm drive 11, see FIG. 9.
  • a pit wall web 10, a pit cover 28 and a holder 27 for supporting sheets are also provided.
  • each clamping device the two axially spaced, radially directed and under the cylinder jacket Surface in the lower clamping device 5 or 6 have register bolts 12, 13, with which two recesses 14, 15 provided in the associated rubber blanket ends 7, 8 cooperate with each other with a rectangular shape or with a semicircular curve.
  • the register bolts 13 are flattened on both sides in the tangential direction.
  • cutouts 28 are provided in the upper clamping strip in the clamping devices 5, 6.
  • the clamping device 5 for the front blanket end 7 can be fixed in the zero position in the circumferential direction by means of a marking 24 on the front blanket end 7 and an associated marking on the forme cylinder 2 (FIGS. 1, 6 to 8).
  • the zero position of the clamping device 5 can also be achieved in that the clamping spindle 3 can be positioned in the circumferential direction on an adjusting stop.
  • the clamping devices 5, 6 are either axially displaceable in the blanket or forme cylinder 2 with the rotatable clamping spindles 3 , 4 by means of the adjusting device 16. 5, the clamping device 5 or 6 is axially displaceable by means of clamping screws 23 with the clamping spindle 3 or 4 via the threaded ring 21 or 22.
  • the clamping devices 5, 6 can also be arranged axially displaceably on the clamping spindles 3, 4. 3 and 4, a bearing block 18, in which an adjusting screw 17 is arranged, is fastened to the clamping spindles 4, 5 is, which carries a driver 20, which is positioned exactly by means of the collar 19 and is positively connected to the lower terminal block of the clamping devices 5, 6.
  • Readjustment in the circumferential direction is carried out in a known manner by turning the clamping spindles 3, 4 via the assigned worm drive.
  • the device is operated as follows: First, outside of the printing press, the rubber blanket ends 7, 8 provided with the recesses 14, 15 are inserted between the terminal strips of the clamping device 5, 6 until the recesses 14, 15 with the register bolts 12, 13 come to rest come. Then the clamping rails of the clamping devices 5, 6 are firmly connected by means of the clamping screws 29. The clamping devices 5, 6 with the rubber blanket 26 are then inserted into the rubber blanket or forme cylinder 2 and the rubber blanket 26 is carefully stretched. Afterwards, a color swipe of the color form, which provides the reference lines for the recessed inline coating, transferred by the printing material, is applied to the dry coating cloth by printing.
  • the markings 24 are attached to the front blanket end 7, which correspond to the markings on the blanket or forme cylinder 2.
  • the rubber blanket 26 with the clamping devices 5, 6 is removed from the printing press, then reinserted and stretched again.
  • a correct adjustment is immediately given when the markings 24 of the rubber blanket 26 on the front rubber blanket end 7 with the associated markings on the Forme cylinder 2 have been brought into line and if necessary a test coating has taken place. If there is an inaccuracy of fit or after a large number of lacquering, it is necessary to retighten the rubber blanket 26, this can be done in the axial direction by means of the adjusting devices 16 according to FIGS. 5 or 3 and 4 and in the circumferential direction by means of the individually rotatable tensioning spindles 3, 4 via worm gear 11.
