Definitions

  • the invention relates to a sword folder according to the preamble of patent claim 1.
  • Such a sword folder is known, for example, from EP 1 176 109 A1 and EP-A-0 639 523.
  • bristles on hold-down devices for braking sheets passing through them is also known, for example, from EP 0 225 576 B1, US Pat. No. 5,405,127 and EP 0 161 988 B1.
  • the object of the invention is based is now to design the sword folder of the generic type so that an exact sheet guide can be realized without side stops.
  • the flexible bristles of the hold-down device By means of the flexible bristles of the hold-down device, a pressing of a sheet on the conveyor belts is ensured and thus a frictional connection between the conveyor belt and the sheet is produced. In addition, the bristles prevent jumping back of the sheet after hitting the Endanschlag issued. If a sheet with sufficient accuracy is taken from an upstream folder, a sufficient sheet centering is ensured even without the use of side stops.
  • the sheet centering can be supported by the use of perforating / scoring tools on a knife shaft between the upstream folding unit and the sword folder.
  • a true-to-sheet sheet alignment is done via the Endanschlag pain.
  • the required contact pressure of the bristles can be finely adjusted via the height adjustment of the hold-down device.
  • the hold-down devices can be adjusted by itself or in addition to the height adjustment at an angle to the sheet travel direction. Appropriately, they are adjusted so that the pressure of the bristles on the side of the Endanschlag worn is greater than at the inlet of the signatures under the hold-down devices.
  • At least two units of conveyor belts and hold-down devices with bristles are preferably used on the right and left of the folding blade.
  • the bristles are inclined so that they form an acute angle between the 30 ° and 80 °, preferably of 70 ° with the incoming folded sheet.
  • the bristles are mounted in rows of holes on the underside of the hold-down device, which are inclined at an angle of 30 ° to 60 °, preferably 45 °, to the rebate plane in the direction of Endanschlag vibration, wherein the bristles in hole row plane at an angle of 60 ° to 80 °, preferably inclined at 70 ° to the arc plane.
  • the bristles is preferably horsehair or synthetic fiber, for. B. of polyamide used.
  • the sword folder 10 has on both sides of an extending in the sheet running direction BL and arranged on a Falzwalzencru 15 folding blade 14 (Fig. 2, 3) a plurality of spaced apart juxtaposed conveyor belts 12 which extend in sheet travel direction BL.
  • a Falzwalzencru 15 folding blade 14 Fig. 2, 3
  • a plurality of spaced apart juxtaposed conveyor belts 12 which extend in sheet travel direction BL.
  • Figs. 1 and 2 only the conveyor belts 12 are shown on the left side of the folding blade 14.
  • the ones on the right are identical.
  • the folding blade 14 is not shown in Fig. 1. It would be located in front of the drawing plane.
  • a transverse strut 24 extends transversely to the sheet running direction BL above the conveyor belts 12, on which spaced-apart stop fingers 16 are provided, which extend beyond the sheet support plane 30 down.
  • a hold-down device 18 is provided, which has an extending in the sheet running direction BL bar 22 which is arranged parallel to the sheet support plane.
  • a plurality of bristle bundles 19_with bristles 20 of substantially the same length are arranged close to each other, which extend in the direction of the conveyor belt 12 extend and stand to this at a defined distance.
  • the bristles 20 are inclined in the sheet running direction BL such that the angle ⁇ between the longitudinal axis of the bristles 20 and the folded sheet entering the sheet support plane 30 is preferably 70 ° (FIG. 1).
  • Fig. 4 also shows that the bundles of bristles 19 are mounted in a plurality of parallel rows of holes 21 on the underside of the hold-down bars 18, each hole row plane at an angle ⁇ of 30 to 60 °, preferably 45 °, to the Falzhetebene FE, the rows are directed towards the end stop 16 toward the folding blade level FE.
  • the bristles 20 are inclined in the row order plane at an angle of 60 ° to 80 °, preferably 70 °, to the arcuate plane. As a result, a lateral offset of the bow is prevented.
  • the strips 22 are adjustable in height by an adjusting device (not shown) in order to adjust the contact pressure of the bristles 20 on the conveyor belts 12 can. Furthermore, the bristles are angled over the length of the conveyor belt 12.
  • the arrangement of the bristles 20 extends to the stop fingers 16.
  • the distance of the conveyor belt 12, which cover the bristles 20, is designed so that a sufficient frictional engagement between the conveyor belt 12 and sheet is generated, which prevents lateral displacement of a sheet to be folded that is, that the longitudinal extent of the strips 22 with the bristles 20 corresponds to the length of the longest folding sheet to be processed.
