Definitions

  • the invention relates to a cylinder of a rotary printing press according to the preamble of claim 1.
  • the invention has for its object to provide a cylinder.
  • FIG. 3 shows a printing cylinder with four channels offset by an angle ⁇ ;
  • Fig. 4 shows an arrangement of the channels in printing cylinders of the same size;
  • Fig. 5 vibration amplitudes after rolling over the channel pair (Fig. 1) compared to rolling over a single continuous channel or half the bale width.
  • the amplitudes relate to an “isolated” rollover, that is to say an amplification of the amplitude due to previous, non-decaying rollovers is not taken into account.
  • the destructive interference of the vibrations excited by successive channel beats minimizes the amplitude of the resulting total vibration within a determinable production rate range.
  • the destructively interfering channel beats must follow one another closely in order to best meet the interference condition with regard to amplitude and phase relationship, because
  • each printing cylinder has divided channels.
  • each cylinder for example, are ⁇ by a defined angle, offset 5 ° to 40 ° or 13 ° to 21 °, in particular 16 ° to 18 °.
  • the channels in adjacent printing cylinders in which a double circumferential cylinder is adjacent to a single circumferential cylinder, are arranged such that the channels roll on each other with every or every second revolution of the single circumferential cylinder.
  • channel pair the channels shown in FIG. 1, offset by the angle ⁇ calculated according to the above formula, are referred to as “channel pair”.
  • the resulting oscillation amplitude after rolling over the channel pair in comparison with rolling over a single channel across the entire bale width and in comparison 5 is shown by way of example for an angle ⁇ optimized for the production rate of 70,000 copies, for example newspaper pages per hour, for rolling over a single channel going over half the bale width.
  • the vibration amplitude after rolling over the channel pair is up to 60% smaller than that after rolling over a single divided channel due to the destructive interference (FIG. 5).
  • the 1st harmonic of the bending vibration contributes significantly to the overall vibration amplitude after the channel pair is overrun. 2 - in contrast to the embodiments according to FIGS. 1 and 3 - does not have the symmetry of the 1st harmonic, this is far less excited in the embodiment according to FIG. 2. This is offset by the disadvantage of the embodiment according to FIG. 2 that one channel run occurs "outside” and the other "inside". In general, this causes a different degree of excitation of the fundamental vibration and thus a reduction in vibration damping through destructive interference. Furthermore, the embodiment according to FIG. 1 is to be favored over the embodiments according to FIGS. 2 and 3 both with regard to the possibilities of panoramic printing and also because of the simplicity of introducing the tensioning channel mechanism.
  • FIG. 1 thus represents the cheapest implementation variant.
  • the cylinder is preferably designed as a form or transfer cylinder with channels for fastening printing plates or blankets.
