Definitions

  • the invention relates to a device for producing an additional fold in folders of rotary printing presses according to the preamble of claim 1.
  • Folding devices of the type mentioned above are known. Folding takes place at full paper running speed by means of a rotating folding knife that emerges from the surface of a rotating drum, the folding knife tip being the printed copy to be folded or Print copy package pushes into two oppositely driven folding rollers.
  • a disadvantage of these devices is the folding away at high paper running speed. This leads to damage due to the whip effect that occurs at the trailing ends of the printed copies.
  • the object of the invention is to provide a folding device of the aforementioned type, in which the inevitable whip effect occurs at the trailing ends of the Can print out printed copies without leaving any damage to the printed copies.
  • the middle third of the length of the printed copy is additionally guided with the tapes by remaining areas of the folding roller surface without the middle part of the printed copy being rolled out between the folding rollers. This enables high folding speeds in high folding quality.
  • folding rollers 4 and 5 Each of the folding rollers 4 and 5 drives a conveyor belt system 6, 7.
  • the folding rollers 4 and 5 are each on a pair of swivel lever 8 or 9 rotatably attached.
  • the pivot levers 8 and 9 are pivotally mounted about the pivot points 10 and 11.
  • the folding gap between the folding rollers 4 and 5 can be adjusted by adjusting the mechanisms 12 by pivoting the pivot levers 8 and 9 to the thickness of the printed copy 2 to be folded.
  • the folding rollers 4, 5 grip the printed copy 2 introduced into the folding gap by the folding knife 3, form the fold 32 and guide the printed copy 2 to the delivery wheel 13 with the aid of the conveyor belt system 6, 7.
  • the folding rollers 4 and 5 have cutouts 14 and 15, respectively. These cutouts 14 and 15 enable the trailing end 16 of the printed copy 2 to flutter freely, while the printed copy 2 is fed to the delivery wheel 12 through the belts 17 and 18 of the conveyor belt system 6, 7.
  • Fig. 3 shows schematically how the folding rollers 4 and 5 are designed.
  • a printed copy 2 was drawn in with a broken line to show which area of the printed copy 2 touches where the folding roller 4 and 5, respectively.
  • the folding roller 4 and 5 is rotatably and drivably mounted with its axes 19 and 20 in the pairs of pivot levers 8 and 9, respectively.
  • the part 21 of the folding roller surface which forms the fold of the printed copy 2 is continuous and has only incisions 22 and 23 for guiding the strips 17 and 18, respectively. This part 21 forming the fold of the printed copy 2 extends in the unwinding direction over approximately a third of the length of the printed copy 2.
  • the area 24 adjoining the part 21 of the folding rollers 4 and 5 is provided with a cutout 25 which is delimited on the left and right by the remaining areas 26 and 27.
  • the width of the recess 25 is dimensioned so that the pressure example 2 comes to rest on both sides with the edge zones on the remaining surfaces 26 and 27.
  • guide rings 28, 29 are arranged to support the bands 17 and 18, respectively.
  • the length of the area 24 corresponds to approximately one third of the length of the printed copy 2, i.e. that the second third of the printed copy, viewed in the unwinding direction, covers this area 24.
  • the trailing end of the printed copy 2 can flutter freely.
  • the folds caused by the whip effect and the resulting fluttering of the printed copies 2 are not rolled in, but they are smoothed out when the printed copies 2 are transported, since these are only held by the belts 17 and 18.
