Definitions

  • the invention relates to a folding machine according to the preamble of independent claim 1, as well as a pressing plant for a folding machine.
  • folding machines are used to fold or fold printed matter every kind used.
  • the printed matter to be folded is fed individually to the folder.
  • the sheets of paper are folded in a folding unit, which for example consists of a Cascade of rolls or rollers.
  • the inserting machine packs the folded ones Printed matter ready for dispatch in envelopes.
  • the folded documents for example with a roller table or with a conveyor belt next processing machine, e.g. another folding machine or fed to an inserting machine.
  • Such papers can, for example, be labeled, then folded and finally processed by gluing to the document ready for dispatch. There is no need to pack the document in an envelope.
  • the gluing usually takes place in the lateral marginal zones and in the lower, possibly also in the upper Edge area where the adhesive is applied, or already at the unprinted paper is applied.
  • To open the by gluing To facilitate closed letters, the peripheral zones are often perforated. By separating the glued edge zones along the perforations the closed document can be opened without any problems, i.e. the recipient has access to the information contained in and transmitted with the document Information.
  • Folding machine of known design also have the property that the Folds are not too much imprinted on the paper. As a result, the folded stack of printed matter are relatively voluminous. It can also it happens that individual folded documents can open again which leads to disruptions in further processing, e.g. lead when inserting can.
  • the object of the invention is to provide a folding machine which lacks described.
  • the folds should be better in the folded Documents are coined.
  • Documents made from adhesive special papers should also be without expensive transport work or expensive additional equipment be glued ready for dispatch.
  • this object is achieved by a folding machine which has the features of the characterizing part of independent claim 1.
  • the Folding unit according to the invention has the features of the characteristic of Claim 7 on.
  • the dependent claims relate to advantageous Embodiments of the invention, i.e. the folding machine, or the Press shop.
  • the paper 11 to be folded is removed from the feeder fed to a folder, which is located inside the housing 10.
  • a folder which is located inside the housing 10.
  • the paper sheets pass through 11 individually, one after the other a certain number of folding roller pairs.
  • the folding length of the individual folds is determined with folding pockets.
  • the The folding machine can stand on a trolley with rollers, as shown here.
  • the finished folded document 11 ' is arranged directly after that Pressing unit 12 fed, where it passes between the pairs of press rolls and in the tray 13, i.e. arrives at a collecting device. Where that Folded paper 11 'is provided with adhesive that sticks under pressure Paper 11 'glued and thus sealed for shipping.
  • the drive of the rollers of the folding machine 1 is shown in Fig. 2, where that Cover plate is folded up. Details of the drive of the pressing plant 12 are 3 can be seen.
  • the drive toothed belt wheel 110 which is on the axis of the Electric motor sits, drives the toothed belt pulley via a toothed belt 111 115 and thus the folder.
  • On the pulley of the toothed belt wheel 115 is a another toothed belt wheel 113 placed, which also has a toothed belt drives the gear 114 for driving the press rolls of the press plant 12.
  • This gear 114 drives the gear 112, which for safety reasons part of its circumference is covered with a protective cap 1120.
  • the toothed belt wheel 110 can with a Slip clutch must be mounted on the drive shaft.
  • the translation of the Gearboxes are chosen so that the peripheral speed of the press rolls equal or slightly higher than the transfer speed of the folder is.
  • the speed of the press rollers may be greater if the Sheets folded in the folding unit from the press rollers of the press unit first be adopted if they have already been released by the folder or just released.
  • the pressing plant 12 is designed such that the module on the cams on the Is hung on the inside walls of the folding machine while doing so Drive gear 112 engages in the driven gear of transmission 114.
  • the Gears of the transmission 114 and also the gear 112 are advantageously made a plastic such as Made of Teflon or hard polyethylene. This Plastics have the advantage that the material, just like by the way Timing belt that is self-lubricating and no additional lubricants such as oil or fat are necessary. This reduces the risk that the processed Products become dirty, which is important when processing paper.
  • the front view of the exit side of the pressing plant 12 is shown in FIG. 4.
  • the Both press rolls 121 and 122 press rolls are paired with gears 121 'or 122' driven on one side. It would also be conceivable for the press rolls 121, 122, the roller body of which is a hollow tube, to be driven on both sides.
  • the upper press roller 121 is supported in the two side wall parts 124, 125 and the side wall parts are hinged 1222/24 or 1222/24 ' connected to each other and around the axis of the spacer and frame part 123 swiveling.
  • a brush made of electrically conductive threads attached which serves to press the folded, pressed, pressed out of the press shop and electrically discharge the glued paper sheet, i.e. electric charge the is derived from the paper sheet.
  • the upper press rolls 121, 126 of the two pairs of press rolls shown.
  • the upper press roller 126 is also around a spacer and frame part 123 'of the pressing plant 12 swiveling.
  • the contact pressure or the contact pressure of the press rollers 121, 122, or 126, 127 of the two pairs of press rolls is with the two Threaded bolts 128 and 128 'set.
  • the swiveling press rolls 121 and 126 are based on the two Side views of the pressing plant in FIGS. 6 and 7 explained. reference 6 and 7, the two lower rollers 122, 127 of the two pairs of press rollers in the lower part 1222, or 1222 'of Sidewall stored.
