Definitions

  • the invention relates to a folding machine with at least one upsetting unit and a plurality of folding unit units, used for the parallel fold, for folding and cross-folds, as is also known as a "combined folding machine" and for folding sheets of sheet-like materials, in particular printed ones Paper sheet is used.
  • a folding blade unit for the cross fold is arranged on a frame side wall.
  • the position of the folding blade corresponds to the center of the machine format, so that the folding blade unit is of different lengths for different machine widths.
  • a larger machine width requires a stable and torsion-free attachment of the folding blade unit to a correspondingly stable frame side wall.
  • this one-sided fastening of the folding sword unit to a side wall of the frame is no longer up to the requirements of fold fold quality; Vibrations of the bracket and the frame side wall impair the exact fold breakage.
  • the invention is therefore based on the object of eliminating the disadvantages mentioned of the conventional designs of combination folding machines and thereby ensuring a stable, vibration-free and torsion-free arrangement of the folding blade units for different machine widths.
  • the folding blade units with cantilevers are attached to a rigid frame bridge extending between and fixed to the frame side walls at the exit end of the machine frame and in that the frame side walls extend deep recesses over the area of the folding blade units exhibit.
  • the setting elements for the operator are clearly visible and freely accessible, such as the sheet hold-down device arranged above the conveying device, the sheet stops and the associated operating elements, but also the knife shafts or output shafts with transport rollers and cutting device arranged at the output of the compression fold unit used for the parallel break - or perforating devices.
  • the sheet adjustment and the stub sheet removal are much easier and faster to carry out than with the previously known types.
  • the invention enables an advantageous further development to the effect that the folding blade units carried by the rack bridge are driven coupled by a common drive, preferably in such a way that they are driven by an electric motor attached to the frame bridge via an element, for example a toothed belt, which couples the drive wheels of the folding blade units and runs parallel to the plane of the frame bridge.
  • a common drive preferably in such a way that they are driven by an electric motor attached to the frame bridge via an element, for example a toothed belt, which couples the drive wheels of the folding blade units and runs parallel to the plane of the frame bridge.
  • a sheet feeder of known design, not shown, for separating and delivering the paper sheets is followed by a compression folding unit formed from folding rollers 1 and folding pockets 2 for the parallel break, at the output of which knife shafts or output shafts with transport rollers and cutting or perforating devices 15, 16 are provided.
  • a rigid frame bridge 5 which extends between these side walls and is fastened to them.
  • Brackets 6 are attached to it, which in the example shown are formed by hollow profile pieces of equal length and of a sufficiently large cross-section which provides resistance to vibrations.
  • Such a boom 6 fastened in the central region of the frame bridge 5 carries a cross-fold folding sword unit 7 with a folding sword 12.
  • three-fold folding-sword unit 8 with a folding sword 13 and a folding-sword unit 9 with a folding sword 14 are held on the same booms, which are lower than the middle boom 6.
  • the folding blade units 7, 8 and 9 are driven together by an electric motor 17 which is on or in the lower part of the frame bridge 5 is mounted so that its output element is on the back of the frame bridge 5.
  • the drive wheels 20, 21 and 22 of the folding blade units 7, 8 and 9 are also mounted there.
  • the gear means for transmitting motion to the folding swords go through the hollow profiles 6.
  • the machine is equipped with devices, known per se, not shown, for laying out the sheets after the parallel break or after the cross break or after one or the other of the selectable three breaks.
  • An opening 18 is provided in the frame bridge 15 for laying out sheets which are only subjected to the parallel break.
  • the conveyor devices of a known type, which forward the sheets after each fold.
  • Associated folding rollers 10 are mounted below the cross-fold folding blade unit 7, and folding rollers 11 and 9 are stored below the three-folding folding blade units 8 and 9.
  • the folding sheets coming from the folding rollers 1 of the parallel folding unit do not arrive by means of the Drawn conveyor below the cross-fold folding sword unit 7, where they are driven by the folding sword 12 between the folding rollers 10.
  • the machine is set up so that the sheet provided with the cross fold is passed on or processed. It can thus be led out of the machine immediately and laid out or, depending on the choice, fed to one of the three-break folding units on the machine, either to the right or left of the cross-fold folding unit, where it is in the three-break folding unit 8 from the folding sword 13 or in the three-fold folding blade unit 9 is driven by the folding blade 14 between the folding rollers 11.
