Definitions

  • the invention relates to a device on the folding apparatus of rotary printing presses for storing the folding knives, folding jaws and punctures by means of bearing bridges provided at least on the cylinder faces, which are screwed onto the cylinder body.
  • Bearing bridges are generally known and have the shape of a circular section.
  • the cast iron cylinder bodies normally used have recesses for the bridges on the end faces. These are provided with bearing bores, adapted and screwed to the cylinder body and over-tightened or smoothed with it, or the bores are only drilled precisely after the bridges have been put in place.
  • each bearing bridge is made individually, so that an exchange or the use of series parts may not be possible even for different cylinder diameters. Furthermore, deviations in parallelism or in the accuracy of turnover cannot be compensated.
  • the object of the invention is to provide a device on the folder, which enables the use of series parts for the storage of the folding knife, folding jaws and spindle spindles with different cylinder diameters and at the same time easily ensures precise parallelism and high turnover accuracy with two or more folding blades or folding jaws .
  • the feature of claim 2 shows an advantageous embodiment of the invention, wherein the spacers can be ground to a precise dimension with a simple surface grinding machine during cylinder assembly.
  • the paper web 1 which has not yet been cut is fed to the cylinder part of the folder 5 via pairs of pull rollers 2, 3 and 4.
  • the knife cylinder 6 cuts the paper web 1 to specific section lengths with its knife 7.
  • the knife 7 works here with two rubber rails 8 in the folding knife cylinder 9.
  • the two folding blades 10 of the folding blade cylinder 9 in turn work together with the two folding jaws 11 of the folding jaw cylinder 12.
  • the copies 13 folded by the folding flaps 11 are then fed to a paddle wheel 14 which deposits the copies 13 on a belt line 15, from which they are transported out of the folding apparatus (FIG. 1).
  • the cylinder body 16 of the folding knife designed as a supporting body serzylinders 9 is mounted on the axis 17 and carries the bearing bridges 19 for the folding knife spindle 20 via two spacers 18.
  • the bearing bridges 19 and the spacers 18 are screwed to the cylinder body 16.
  • the cylinder body 16 and the two bearing brackets 19 are uniform series components.
  • the spacers 18 are designed in their thickness according to the respective cylinder diameter, so that the dimension between the folding knife spindle 20 and the center of the axis 17 can be maintained very precisely.
  • the puncture spindles present in the folding knife cylinder 9 are also supported in the same way, but were not shown because of the clarity.
  • cylinder bodies 22 are arranged on both sides, on which the bearing bridges 23 are screwed via spacers 24.
  • the spacing between the spindle 25 of the jaw 11 and the center of the axis 21 can be determined very precisely via the spacers 24 using the spacers.
  • the cylinder jacket itself can consist of simple webs on which the folded copies 13 are deposited.
  • the partial cross section shown in FIG. 2 can relate to the folding knife cylinder 9 or the folding jaw cylinder 12.
  • the cylinder bodies 16, 22 are fastened on the axis 17, 21 and carry the spacers 18, 24, which in turn are screwed together with the bearing bridges 19, 23 to the cylinder body 16, 22 via the screws 26.
  • Either a folding knife spindle 20 or a spindle 25 of the folding flap 11 can be mounted in the bearing bridge 19, 23.
  • the storage takes place in a known manner, for. B. via a bearing bush 27.
