Definitions

  • the invention relates to a device for fastening a flexible printing plate on the form cylinder of a printing machine the preamble of claim 1.
  • EP 534 579 A2 shows a plate tension in which the Forme cylinder a cylinder pit running in the axial direction has one edge carrying the leading plate leg.
  • the cylinder pit also contains a rotatable spindle on which U-shaped leaf springs are distributed over the width of the forme cylinder are arranged.
  • One leg of the leaf springs is hook-shaped folded and engages when turning the spindle in the hook-shaped trailing plate leg. Of the other leg of the springs presses the leading plate leg against the wall of the cylinder pit.
  • the leading plate leg on the wall of the Cylinder pit is not reliably held.
  • this object is achieved with a generic Device through the application of the characteristics of the mark of the Claim 1 and by a method according to the claim 6 solved.
  • the device secures the leading plate leg not only on the wall of the cylinder pit, but gripped and tensioned this, d. H. pulls him into the cylinder pit. This will make the leading plate edge in the correct position on the edge of the cylinder pit drawn.
  • the pressure plate is parallel to the channel edge on the Form cylinder positioned before it is wrapped around it. So there will be register errors, especially Diagonal register error, avoided when clamping the pressure plate.
  • the forme cylinder 1 shown in detail in FIG. 1 has a cylinder pit 2 running in the axial direction.
  • a Pit wall 3 is at an acute angle to the cylinder surface and forms with this an edge 4 on which the leading Plate leg 5 of the pressure plate 6 is added.
  • a spindle 7 is arranged, which at the ends of the Cylinder pit 2, not shown, is rotatably mounted.
  • the Spindle 7 supports the width of the pressure plate 6 to be tensioned distributes several angled leaf springs which are hook-shaped by approximately 90 ° 8. These work with the hook also around 90 ° angled end of the trailing plate leg 9 together. Instead of the individual leaf springs 8, one could look over the Continuous leaf spring extending the width of the pressure plate be provided.
  • the spindle 7 also has a driving edge 10 with a V-shaped notch 11 of the leading Plate leg 5 works together.
  • a lever 12 is attached, which is articulated is connected to a spring-loaded pivot lever 13 (Fig. 3).
  • Swivel lever 13 contains a rod 14 on which against the force a compression spring 15 a fork head 16 can be deflected.
  • the pivot lever 13 With a Roller 17, the pivot lever 13 is supported in an abutment 18th swiveling. Furthermore, the pivot lever 13 presses with his spring-loaded clevis 16 onto a pin 19 of the lever 12.
  • the clamping spindle 7 takes first the position shown in Fig. 1.
  • the corresponding position of the the spindle 7 actuating lever 12 and 13 is in Fig. 3rd shown.
  • the deflectable pivot lever 13 presses the lever 12 in a stop position.
  • the spindle 7 pivoted.
  • the lever 12 and the pivot lever 13 in their stretching position, d. H.
  • the driving edge 10 stretches again the leading plate leg 5, and the leaf springs 8 reach into the hook-shaped fold of the trailing one Plate leg 9 and tension it. So both are leading and trailing plate legs 5, 9 under the Biased force of the compression spring 15, d. H. the spindle 7 rotates until the clamping forces on the plate legs 5, 9 of the Spring force of the pivot lever 13 keep the balance.
  • the spindle 7 is moved into the position shown in FIG. 1 shown position pivoted. Then the trailing one Plate leg 9 removed from the cylinder pit 2, the pressure plate 6 unwound by rotating the forme cylinder 1 and the pressure plate 6 with its leading plate leg 5 from the Cylinder pit 2 lifted out.
  • the pivoting of the adjusting spindle in one direction or the other is advantageously carried out by applying a force F1 or F2 to the Lever 12 on this side or beyond its pivot point (see Fig. 3).
  • the forces can be generated by working cylinders arranged in the frame be applied.
  • the device is good for you suitable for automatic plate change.
  • the notch 11 of the leading plate leg 5 is in the Embodiment designed V-shaped.
  • One is appropriate Leg of the notch 11 good for taking along by the driving edge 10, while the second leg is advantageously on the pit wall 3 supports.
  • the notch can also be otherwise formed, for example U-shaped.
  • the leading plate leg 5 can also wear knobs on which the Driving edge 10 attacks.
  • the leading plate leg can also provided with slots running in the axial direction of the cylinder be, in the area of which the pressure plate, driving webs, for Spindle is arched out.
  • the trailing plate leg 21 of the pressure plate 22 to be tensioned Axial direction of the forme cylinder 23 arranged window-shaped Cutouts 24 on. These reach into the clamping position hook-shaped leaf springs 25 of the spindle 26. Further construction and Function and the same as the previous embodiment therefore not described in detail.
