Definitions

  • the invention relates to a printing cylinder, in particular a blanket cylinder an offset web-fed rotary printing press having an axially extending one Channel in which the ends of a compressible on the cylinder blanket (Blanket) by means of a clamping channel arranged in the clamping mechanism can be fixed.
  • the present invention comprises essentially novel ideas at least an edge of the clamping channel 2 of the printing cylinder, i. at the preferred here described blanket cylinders of an offset web-fed rotary printing press in Seen circumferentially movable to design.
  • This mobile design makes it possible by changing - in particular by twisting the clamping mechanisms 3 to open the clamping channels 2 and close, so that the ends of the not closer to the printing cylinder 1 according to Figures 1 to 4 clamped Blankets can be fixed and on the other hand by movement at least one edge of the clamping channels 2, the clamping channels are closed, so that effective, i. the effective width of the clamping channel during the printing operation much lower than conventional printing cylinders, which as stated a minimization of the vibration excitation by line force excitation results.
  • Figure 1 shows the printing cylinder, as mentioned above, a blanket cylinder in a "closed state", as will be explained below.
  • the printing cylinder 1 has a running in Zylinderachsplatz clamping channel 2 its periphery, in which a clamping mechanism 3 is arranged.
  • a clamping mechanism 3 is arranged in principle
  • the clamping mechanism 3 with a form a circular cross-section, i. to use a clamping spindle 3, the in an axially extending bore of the printing cylinder 1 can be arranged.
  • a preferred embodiment according to Figures 1 and 3 of the clamping spindle 3 consists in that they have the same radius of curvature over a portion of their circumference or the same circumferential contour as the printing cylinder has, so that this Area of the clamping spindle 3 forms the movable edge 8 of the clamping channel 2, namely when the clamping spindle 3 is rotated.
  • the scope of the clamping spindle 3 can be more curved, so that a correspondingly small hole in the printing cylinder 1 for receiving the clamping spindle 3 can be provided.
  • the ends 4, 5 of the blanket - as stated of conventional design - can be reinforced so that they in the P-shaped holding part in the form of a retaining rail. 6 can be fixed when the support rail 6 is pulled into the cylinder obliquely.
  • the Retaining rail 6 can by holding means, such as screws 10 in the clamping channel. 2 being held.
  • Figures 3 and 4 a further variant is employed, in which also a Clamping spindle 13 is used, which is arranged in the clamping channel 12.
  • Figures 3 and 4 show a practical fully cylindrical design of the clamping spindle 13 with an axially extending Clamping slot 21, in which the ends 14, 15 of the blanket can be inserted and fixed are, again similar elements as in connection with Figures 1 and 2 described can be used. These are a retaining rail 16 and to the Fixing a screw 20.
  • FIG. 3 By rotating the clamping spindle 13 can also be the clamping channel 12 of a closed position, as shown in Figure 3, in an open position by Rotation of the clamping spindle 13 are brought in the direction of arrow 17.
  • the closed Condition according to FIG. 3 forms a circumferential section of the clamping spindle 13 practically the movable flank 18 'of the tensioning channel, while the other side 18 by the formation of the printing cylinder 1 in the embodiments described here fix is.
  • Figures 3 and 4 show that the circumference of the clamping spindle 13, which forms the movable edge of the clamping channel 12, also a again Has curvature which corresponds approximately to the radius or with the circumferential curvature of the printing cylinder 1, so that a continuous unwinding of the involved Cylinder is possible.
  • clamping channels and the clamping elements are possible within the scope of the invention, so that the protection of the invention not only to the preferred embodiments according to Figures 2 and 4 limited.
  • the other side of the chip channel, so the other flank be fitted in an analogous manner movable, if so in the individual case is desired.
  • Figures 5 and 6 show another completely novel and individually independent and inventive design of the clamping channel with the following features.
  • the Printing cylinder 1 comprises a pit 22 with a clamping spindle 23, which is a flattening 28 having a curvature according to the cylinder 1 and a slot 25 for receiving the blanket end 25.
  • the other end 24 is in the recess the spindle 23 can be introduced, so that according to Figure 5 with appropriate rotation the clamping spindle 23, the blanket clamped and released according to Figure 6 is and can be taken off.
