Definitions

  • the invention relates to a method for calculating an angle ⁇ between two channels of a cylinder of a rotary printing machine.
  • FR 2 276 177 A discloses a cylinder of a rotary printing press with two channels arranged offset from one another in the circumferential direction by an angle of 48 ° to 57 °.
  • the invention has for its object to provide a method for calculating an angle ⁇ between two channels of a cylinder.
  • the achievable with the present invention consist in particular in that the amplitude is minimized by a passive vibration damping.
  • the channels ⁇ shown in Fig. 1 to offset the angle ⁇ calculated by the above formula are referred to as the "channel pair".
  • the resulting oscillation amplitude after rolling over the channel pair compared to overrunning a single, going over the entire bale width channel, as well as compared to overrunning a single, going over half the bale channel channel is exemplified in Fig. 5 for a on the production rate 70,000 copies, z , As newspaper pages per hour, optimized angle ⁇ shown.
  • the 1st harmonic of the flexural vibration contributes significantly to the overall vibration amplitude after overrunning the channel pair. 2, in contrast to the embodiments of FIGS. 1 and 3, does not have the symmetry of the first harmonic, this is much less excited in the embodiment according to FIG. This is the disadvantage of the embodiment of FIG. 2 compared to that of a channel hit "outside" and the other "inside". This generally causes a differently strong excitation of the fundamental and thus a reduction of the vibration damping by destructive interference.
  • FIG. 1 is to be favored both with regard to the possibilities of panorama printing and because of the simplicity of the introduction of the clamping channel mechanism in relation to the embodiments according to FIGS. 2 and 3.
  • FIG. 1 is the cheapest implementation variant.
  • the cylinder is preferably designed as a forming or transfer cylinder with channels for mounting pressure plates or blankets.
