Definitions

  • the invention relates to a folding device with at least a first longitudinal folding device, with driven separating elements, these subsequent transverse folding devices consisting of folding cylinders, to which a first copy delivery is assigned, and a second longitudinal folding device, which copies can be fed via a conveyor belt section and which can be fed through a second pressurized copy delivery disposes.
  • DE 27 04 813 A1 is known from the prior art, which discloses a folder for rotary printing presses with a magazine cutting option.
  • an additional pair of pull rollers, a control tongue and a further paddle wheel are accommodated below the roller gap between a collecting cylinder and a cutting cylinder in an insert which can be moved into the folder base frame. If the magazine cutting unit is in operation, the puncture needles on the circumference of the collecting cylinder can also be put out of operation.
  • the components included in an additional unit are when the Magazine cutting unit removed from the folder. With this folder, an additional module has to be moved into and out of the folder with every production change from cross fold to tabloid production and vice versa.
  • DE 36 26 287 A1 has become known from the prior art, in which a transverse cutting device, a pulling device arranged upstream of this and an overlapping paddle wheel are accommodated in a slide-in frame that can be partially retracted into the base frame of a folder. This at least requires the insertion and removal of the insert frame from the folder.
  • US 4,368,879 discloses a cutting and folding apparatus on a rotary printing machine.
  • This folding cylinder comprising puncturing cylinders and two delivery points can be loaded with a material web via two material web paths A, B, one of which can feed a material web to the cylinder part of the folding apparatus with a longitudinal cutting possibility, bypassing the first longitudinal folding device.
  • GB 549 067 shows a copy switch for the transport of folded copies, such as newspapers, with which one of two conveying paths can be closed and the other conveying path can be released.
  • a conveyor belt guided over a swivel-mounted roller lies against fixedly positioned conveyor belts and thereby forms a sample switch.
  • the invention has for its object to develop a largely format-variable, pointless folder.
  • the common copy formats can be produced by decoupling the drives of the cutting and folding systems from the drive of the pulling devices, without having to make any changes.
  • the traction devices can feed the material web depending on the format, while the cutting and cross-folding systems work in time. Since the format is adjusted via actions on the drives of the pulling or cutting and cross-folding device, punctures and their Format adjustment can be completely dispensed with.
  • the deflectable transport belts provided after the separating members, the only longitudinally folded copies - for example 4 x 4 pages - can be guided directly into a delivery paddle wheel without requiring the additional equipment of the folder with insertion modules or the like. Since the deflection of the product flow takes place after the cut, it is also possible to dispense with additional cross-cutting devices, which make the folder considerably more expensive.
  • pulses from a sensor are transmitted to the drive for the pulling device.
  • the positioning of the separated signatures can be influenced by regulating the belt speed between the traction devices.
  • the separating members are designed as cutting cylinders which interact according to the principle of scissors cutting.
  • the hack cut previously customary can be eliminated by means of a sawtooth knife, since this previously made it necessary to separate edge areas on the finished product in a separate production cut, also due to puncture punctures.
  • the scissor-cut principle combined with longitudinal cutting devices, the product can now be trimmed completely during production in the folder, which is of particular interest, for example, for envelope production.
  • a further embodiment of the invention provides to drive the deflectable conveyor belts via a separate drive.
  • the belt speed is preferably such that it corresponds to the peripheral speed of the folding cylinder.
  • the deflectable conveyor belts, actuated by pressure medium are brought into positions by means of a paddle wheel mounted in the side parts of the folding apparatus. This means, for example, that 4 x 4 pages of production can be delivered at the push of a button without having to change over, without additional replacement work being required.
  • the further subclaims relate to a delivery belt system which extends under the folder cylinder part and the second longitudinal folding device, and between the longitudinal cutting circular knife arranged between the upper and lower pulling rollers in front of a pair of cutting cylinders.
  • Figure 1 shows the basic frame of a folder shown divided for reasons of clarity.
  • the material web running into the folder from above from a hopper tip 1 of a first longitudinal folding device provided in the superstructure 3 is gripped by a pair of upper feed rollers 4.
  • the material web can also consist of several web strands brought together in the superstructure 3 from a plurality of longitudinal folding devices.
  • the web of material entering a base frame of a folder formed from side walls 2 is conveyed in the direction of a pair of cutting cylinders 9 by upper feed rollers 4 and lower pull rollers 6.
  • Longitudinal cutting knives 5 are provided between the upper feed rollers 4 and the lower pull rollers 6, which are displaceable perpendicular to the web running direction and divide or score the material web.
  • the upper feed rollers 4, which cooperate with the lower pull rollers 6 via a belt drive, are driven by their own or second drive 7.
  • a pair of profiling rollers (8) is attached below the lower pulling roller 6, with which the leading end of the material web can be correctly guided into the gap between the cutting cylinders 9 by embossing a stiffening profile.
  • the cutting cylinders 9 operate according to the principle of a sawtooth cut or else a scissor cut, as a result of which a finish cut of the item still to be folded can be achieved at this early point in time because of the quality of the cut.
  • a plurality of cutting knives are arranged on the circumferential surfaces of the cutting cylinders 9, each working in pairs. By means of a suction device assigned to the cutting cylinders 9, any material web residues that arise during the cutting can be easily removed.
  • the cutting cylinders 9 are operated by a first drive 10.
  • the drive runs from one of the cutting cylinders 9 to a gear 11, which is a Inclusion gearbox and transmits the drive to a gear 12.
  • a gear 11 which is a Inclusion gearbox
  • the drive introduced via the electric motor 10 is transmitted to a folding cylinder 19, from there to a folding jaw cylinder 22 and finally to a gripper cylinder 24.
  • the second longitudinal folding device (see FIG. 2) can also be driven by the electric motor 10.
  • the pair of cutting cylinders 9 there are deflectable conveyor belts 13 and 14, into which the separated signatures pass between the cutting cylinders 9 after the cut.
  • the belt speed of the deflectable conveyor belts 13 and 14 preferably corresponds to the circumferential speed of the folding cylinder 19, folding jaw cylinder 22 and the gripper cylinder 24.
  • the positions 13 'and 14', indicated by dashed lines, indicate the positions into which the deflectable conveyor belts 13 and 14 can be pivoted In order, for example, to direct 4 x 4 pages of folded copies into a paddle wheel 25, which then brings the copies onto a delivery belt 26.
  • the deflection rollers 16 are also pivoted so that the tension of the conveyor belts 13 and 14 is maintained.
  • the deflecting roller 18, which is mounted between the deflectable conveyor belts 13 and 14, serves to deflect and pretension the conveyor belt 13 when the position is pivoted into position 13 '.
  • a sensor 17 is arranged in the region of the deflectable conveyor belts 13 and 14 and transmits impulses to a separate drive 15 of the conveyor belts 13 and 14. By returning the pulse of the sensor 17 to the separate drive 15, the belt speed can of the conveyor belts 13 and 14 can be influenced for the correct positioning of the cut signatures, the speed of the feed rollers 4 and the pull roller 6 can remain unchanged.
  • the folding cylinder 19 is provided on its circumference with two folding knives 20, the folding jaw cylinder 22 here, for example, has opposing folding knives 20 and folding jaws 23. Gripper bridges and folding jaws are provided on the circumference of the gripper cylinder 24.
  • FIG. 2 shows the copy delivery assigned to the transverse fold systems and the device for the second longitudinal fold.
  • a pair of conveyor rollers 27 can be seen, under which there is a paddle wheel 28 which conveys the cross-folded products onto the delivery belt section 29 located under the folder.
  • a further fold variant is provided by the copy feed to a second longitudinal fold device, which is ensured via longitudinal fold feed belts 30 to the fold knife 31. Below this, copies of one are displayed Paddle wheel 33 on a delivery belt pivotable between positions 34 and 34 '.
  • the format-variable folder which operates according to the invention without a point, offers a plethora of production possibilities with a correspondingly versatile configuration of the superstructure 3.
  • a 4 x 4 page copy production can take place immediately after the cut, after the conveyor belts 13 and 14 have been pivoted into the positions 13 'and 14', into the third paddle wheel 25, from where the copies, trimmed on several sides, can be laid out on the delivery belt 26.
  • the downstream transverse folding devices, the folding cylinder 19, folding jaw cylinder 22 and the gripper cylinder 24 can be switched off, as can the device for the second longitudinal fold with 4 x 4 pages of copy delivery, can be deactivated.
  • the 4 x 4 pages copies are then transported out of the folder via the delivery belt system 26, 29 and 34.
