Definitions

  • the invention relates to a method for perforating, punching or creasing paper and cardboard in rotary printing machines by means of prepared band-shaped tools arranged on an assembly film, the band-shaped tools being applied to an assembly film outside the machine before the start of the workflow, and a device for carrying out this method .
  • a device for performing punchings and perforations on printed or unprinted papers on rotary printing presses is known from US-A-3,554,070.
  • the tools consist of angular bands with a long and a short leg.
  • the short leg runs at right angles to the long leg and is designed as a cutting edge.
  • the cutting edge is continuous or interrupted.
  • perforations for example, it is designed like a sawtooth.
  • the tapes are provided with adhesive on the lower surface of the long leg and are glued in the desired position directly onto the impression cylinder of known rotary printing machines.
  • This impression cylinder is in a known manner in contact with the so-called blanket cylinder, which in turn is in contact with the plate cylinder.
  • the paper to be processed is passed between the impression cylinder and the blanket cylinder, and the cutting edges of the band-shaped tools cut the paper at the desired locations.
  • a print image can be transferred from the plate cylinder to the paper via the rubber blanket mounted on the blanket cylinder.
  • leg of the band-shaped tool provided with the cutting edges can only have a maximum height which corresponds to the space between the surface of the impression cylinder and the surface of the rubber blanket on the rubber blanket cylinder. Since the support leg of the tool must also find space in this space, the cutting edges do not extend over the entire height of the short leg — and — either the paper cannot be cut completely through, or there are raised portions and leg impressions on the paper. As a result, the former means that the paper parts cannot be properly separated from one another, and the latter that high stacks of processed paper sheets cannot be formed.
  • the invention is based on the object of avoiding the disadvantages of the known prior art and of providing a solution with which perforations, punchings or scoring of paper and cardboard can be carried out correctly on rotary printing presses without damaging parts of the machine or the printing device . Furthermore, the solution should enable a shorter downtime of the rotary printing press and allow high working speeds.
  • this object is achieved according to the method in that the rubber blanket is removed from the rubber blanket cylinder in a first working step, and an assembly film with band-shaped tools arranged thereon is applied to the rubber blanket cylinder instead of the rubber blanket.
  • the assembly film is prepared outside the machine before the rotary printing machine is shut down, and the ribbon-shaped tools are arranged on it in the desired positions.
  • the desired tool engagement depth and the desired working pressure are set, after which the paper or cardboard to be processed can be carried out between the blanket and impression cylinder.
  • one is carried out simultaneously with or after the mounting film has been applied to the blanket cylinder before the paper or cardboard is processed second film applied to the impression cylinder.
  • the device for carrying out the method on rotary printing presses comprises a plate cylinder with fastening means for an offset plate, a rubber blanket cylinder with fastening means for a rubber blanket and an impression cylinder as well as a device for changing the center distance between the blanket cylinder and impression cylinder and is characterized in that instead of the Rubber blanket a mounting film is attached, on which band-shaped tools are attached with a perforation, punching or creasing, and that a flat film is arranged on the impression cylinder.
  • the band-shaped tools have a T-shaped cross-section, and the central web is equipped with the desired profiling and cutting edge.
  • the central web of the band-shaped tools is at least 1 mm high.
  • the film can be prepared with the band-shaped tools independently of the machine and can be correctly pulled in and fastened by means of the facilities provided on the blanket cylinder for fastening the blanket.
  • the set-up and downtime on the machine can be reduced by at least 50% compared to the machining process with tools glued to the impression cylinder.
  • Another advantage is that the foils can be used several times by being easily removed from the blanket cylinder and stored after the machining process has ended. After removing the mounting film with the band-shaped tools, the rubber blanket can be pulled back on and the printing process can be continued.
  • the prepared mounting film is removed from the storage again and applied to the rubber blanket cylinder instead of the rubber blanket.
  • the band-shaped tools can be used several times. Resharpening the blunt tools also increases their lifespan.
  • This method according to the invention and the corresponding device also enable printers which have only one rotary printing machine and no punching machine to perform perfect perforation, punching or creasing work.
  • the cylinder arrangement of a rotary printing press shown in FIG. 1 consists of a plate cylinder 1, a blanket cylinder 2 and an impression cylinder 3.
  • a similar but smooth mounting film 7 is also attached to the impression cylinder 3.
  • the center distance 8 between the blanket cylinder 2 and the impression cylinder 3 is adjustable and adjustable with devices not shown.
  • the gap 9 between the cylinders 2 and 3 in the example described is 1.9 mm when the cylinders are completely retracted.
  • a section of a band-shaped tool 6 is shown as an example, which is a perforation tool.
  • This band-shaped perforation tool has a T-shaped cross section with a foot beam 15 and a central web 16.
  • the central web 16 is 1.9 mm high, this dimension including the thickness of the foot beam 15.
  • the central web 16 carries the cutting edge 19 on the upper edge.
  • the central web 16 is further interrupted by gaps 18, whereby profiled teeth are formed. Spaces 18 un felt teeth 17 and the cutting edge 19 have corresponding dimensions depending on the desired shape of the profile.
  • the base 20 of the T-beam 15 is coated with a double-adhesive tape, which is protected by a cover tape when not in use.
  • the desired network of ribbon-shaped tools is initially provided on an assembly film 5 known in printing technology 6 attached.
  • the thickness of the mounting foils 5 and 7 is approximately 0.25 mm in the example described.
  • the band-shaped tools 6 are attached to the mounting film 5 in the flat state of the film 5 and outside the rotary printing press.
  • the protective tape on the base 20 is removed and this base 20 is glued onto the mounting film 5 in the required position.
  • the rubber blanket (not shown) is removed from the blanket cylinder 2, and instead of this blanket the mounting film 5 is pulled onto the blanket cylinder 2 and fastened.
  • the attachment can be carried out by means of the existing attachment means 10 or additional aids.
  • the band-shaped tools 6 adapt with the mounting film 5 to the surface of the blanket cylinder 2 and thereby form the rotating tool surface for processing the paper sheets.
  • a protective film 7 is applied to the impression cylinder 3, which also consists of a known mounting film. This is necessary if the impression cylinder 3 is roughened, as is the case, for example, in straight printing machines.
  • the center distance 8 or the space 9 between the blanket cylinder 2 and the impression cylinder 3 can normally only be adjusted in a small area, approx.
  • the band-shaped tools 6 can be arranged in any manner on the mounting film 5, so that all desired types of perforations, punchings or creases can be produced.
  • the dimensions chosen in the example described allow the processing of cardboard sheets with a weight of more than 300 g / m2. The depth of cut is dependent on the height of the central web 16 or the profile teeth 17 and the center distance 8.
  • the film 5 is kept for later use and can be used again for a similar processing operation.
  • the rubber blanket is pulled back onto the blanket cylinder 2, and the protective film 7 is removed from the impression cylinder 3.
  • the rotary printing press is now ready for further operations.
