Definitions

  • the invention relates to a folding apparatus of a printing press according to the preamble of claim 1.
  • Folders are used for the formation of folds on printed substrates, wherein in web-fed known from the prior art, a web-like substrate is usually first passed through a first longitudinal folding unit having at least one former, so as to form a longitudinal fold on preferably not yet severed substrate.
  • the web-shaped printing material is guided in the direction of a cutting unit.
  • copies of the web-shaped substrate are cut off by cross-cutting.
  • the cutting unit is usually followed by a Querfalzü downstream, comprising at least one folding blade and a jaw cylinder. Copies separated on the cutting unit are held on the folding blade cylinder with the help of puncturing needles and moved by means of the folding blade cylinder in the direction of the jaw cylinder.
  • second Querfalze can be formed between the jaw cylinder and a gripper cylinder, which cooperates with the jaw cylinder.
  • the copies thus provided with a longitudinal fold and with at least one transverse fold can, starting from the transverse folding unit, reach into the region of a second longitudinal folding unit, which usually comprises a plurality of longitudinal folding devices designed as folding tables.
  • a folder is for example off EP 0 210 634 A2 known.
  • second longitudinal folds can be formed on the already pre-folded copies which run parallel to the longitudinal fold formed in the first longitudinal folding unit.
  • the second Leksfalzü may be arranged downstream of another Querfalzappel.
  • a so-called magazine structure may also be present, wherein in the magazine structure no longitudinal folding but longitudinal separation of the printing material takes place.
  • folders are known in which the folding blade of the Querfalzü is designed as a collecting cylinder, wherein in a collective production of the same before forming a Querfalzes several separated from the web-shaped substrate by cross cutting copies are stored or collected on the folding blade on each other.
  • a substantially linear transport path follows, in order to transport the transversely folded copies starting from the transverse folding unit into the region of the longitudinal folding unit and / or transverse folding unit positioned along the transport path.
  • the cross-folded copies are guided in the region of the substantially linear transport path via belts, which are operated at a constant speed, and braked in the range of brake brushes to the transport speed of the copies to the positioned in the region of the linear transport path L jossfalzü and / or Querfalzü adapt.
  • Out EP 0 170 179 A1 is a provided with elastic carriers circulating transport device on a jaw cylinder for the adoption of folded products known.
  • the present invention has the object to provide a novel folder of a printing press.
  • This object is achieved by a folding apparatus according to claim 1.
  • the substantially linear transport path comprises a guide device for each exemplar to be transported and an electric linear drive cooperating with the guide device.
  • the linear transport path which adjoins the at least the folding blade and jaw cylinder comprehensive Querfalzü the folder, for each item to be transported a guide device and cooperating with the guide means electric linear drive.
  • the specimens can be braked in a defined manner without the risk of the specimens being twisted during transport along the linear transport path.
  • bands and brake brushes is omitted in the folder according to the invention.
  • Fig. 1 shows a highly schematic representation of a folding apparatus of a printing press, wherein the folder of the Fig. 1 a cutting unit 10 comprises, in the area of which are separated by a printing substrate 11 by cross-cutting copies.
  • the copies separated from the printing material web 11 in the area of the cutting unit 10 reach, starting from the cutting unit 10, in the region of a transverse folding unit 12, the transverse folding unit 12 corresponding to FIG Fig. 1 a folding blade cylinder 13, a jaw cylinder 14 and a gripper cylinder 15 includes.
  • the copies 10 separated from the printing material 11 can be provided with two transverse folds.
  • transversely folded copies 16 reach, starting from the transverse folding unit 12, into the region of a substantially linear transport path 17, according to FIG Fig. 1 along the linear transport path 17 a Leksfalzhow 18 is arranged to form at the transversely folded copies 16 Leksfalze.
  • a Leksfalzread 18 is arranged to form at the transversely folded copies 16 Leksfalze.
  • the linear transport path 17 may further be arranged a Querfalzü, which is preferably downstream of the Ltician 18.
  • the transport path 17 for each copy 16 to be transported an unillustrated guide means, with each non-illustrated guide means, a non-illustrated electric linear drive cooperates ,
  • Each guide device can be driven by the respective linear drive in such a way that a copy 16 to be transported along the linear transport path can be detected by a guide device with a relative speed of approximately zero.
  • each guide device can be driven by the respective linear drive in such a way that it can be braked together with a specimen 16 detected by it to a speed which is adapted to a production speed of the longitudinal folding unit 18 and / or transverse folding unit positioned along the transport path 17.
  • the guide devices can be designed as grippers, which preferably grip the specimens in the region of their front edge.
  • the guide devices can also be designed as sliding elements or other transport elements.
  • the guide means are not operated at a constant speed, but rather decelerated on the linear drives when they grasp a specimen 16.
  • the guide devices are particularly adjustable in order to adapt the same to variable Exemplardicken.
  • the folding apparatus according to the invention comes in the region of the linear transport path 17, which adjoins the Querfalzappel 12 and the transport transversely folded copies 16 in the direction of a L Lucassfalzappel and / or Querfalzü, without conveyor belts and brake brushes.
  • the function of the conveyor belts take over the guide devices in the folder according to the invention.
  • the function of the brake brushes take over the linear actuators in the folding apparatus according to the invention.
