Definitions

  • the present invention relates to a folder in a web-fed rotary offset printing press according to the preamble of claim 1.
  • Web-fed rotary printing machines print on a continuous web, e.g. made of paper.
  • the continuous web is cut in a header of a folder to form signatures which are then folded or dispensed.
  • US 5,740,709 describes a double-cut folder.
  • the cutting cylinders perform in the described folder during the cutting process by no clamping, resulting in the described device has the problem that it may cause relative movements in the signatures during the cutting process, which usually lead to stepped cutting edges.
  • Applicant's non-prepublished European patent application EP 1097892 discloses a cutting device comprising a revolving conveyor belt with an integrated cutting blade, in which a first cut is made by a first cutting cylinder and subsequently a second cut by a second cutting cylinder having cutting wheels.
  • the conveyor belts or belts have portions of different cross-sectional thickness and pass between the cutting discs correspondingly provided with corresponding recesses to grasp the cut signatures and divert the signatures into two streams.
  • the straps grasp the leading edge of the signature after the second cut and thus do not help to maintain the position of the signature during the second cut in a controlled manner.
  • EP 0449006 discloses a folder according to the preamble of claim 1.
  • the invention is accordingly based on the object to provide a device for the controlled cutting of signatures, with which the accuracy with respect to the "cut-to-cut” measure and the "pressure-to-cut” -Milleres, that is the so-called Cut register, is improved.
  • a folding apparatus has a first cutting and clamping device for partially cutting a printing material web, in particular a printed paper web, in which a first series of juxtaposed cuts is introduced into the web and at the same time the web is clamped by the clamping device becomes.

  • the first and / or second cutting cylinder and the associated anvil cylinder are preferably cantilevered to allow easy replacement of the belts.
  • the present method provides a two- or double-cut arrangement which enables the web to be held during the first and second cutting operations in a clamped predetermined position, thereby increasing the tension and accurate alignment of the web Track, or the signatures can be met during the cutting process with very high accuracy.
  • the present device is particularly preferably suitable for use in conjunction with web-fed rotary printing presses operating at a high speed, e.g. Printing machines that operate at more than about 610 m per minute, since the web and the cut signatures are held and precisely guided even at high speeds due to the clamping operation on the first and second cutting and clamping device.
