Definitions

  • the invention relates to an apparatus and a method for the production of corrugated board products which are e.g. serve as packaging material.
  • Corrugated board products are made from individual paper webs, with a corrugated product comprising smooth and corrugated paper layers joined together.
  • Corrugated board products are manufactured in a continuous process.
  • Out DE 1 561 510 discloses a method for the continuous production of stiff corrugated cardboard, in which two webs of corrugated cardboard with oblique corrugations are glued to each other.
  • the webs with oblique corrugations are made by passing one paperboard web each between two coupled corrugation cylinders, the corrugation cylinders being made with helical corrugations.
  • a paperboard web guided by the coupled corrugation cylinders is brought to a smooth path with respect to the running direction of the corrugating machine at an angle ⁇ which lies in a horizontal plane and adhered thereto. This creates a composite web.
  • two composite webs are connected together so that their corrugated sides are glued together without interposition.
  • a disadvantage of the method according to DE 1 561 510 is that the device required for this purpose is designed only for corrugated without an intermediate layer between the composite webs.
  • Other types of corrugated board, in particular those with an intermediate layer, can only be produced after a complicated conversion of the device used for this purpose.
  • such devices have a considerable width and take up a lot of space.
  • FR 1 212 042 A discloses a machine for producing corrugated cardboard in which two single-ply corrugated board webs are fed and glued together directly to a final product. In this case, either a single-flow product or a double-flow product can be obtained.

Furthermore, the device is provided with a merge, which is designed to connect the single-flow corrugated cardboard webs with each other.
  • the merge has a convergence region in which the corrugation profile of the first and second single-flow corrugated webs are mutually adjusted. The mutual adjustment takes place via a merging of the single-ply corrugated board webs, wherein the top and bottom points of the single-ply corrugated board webs respectively engage with each other.
  • corrugated webs of the single-ply corrugated board webs each form substantially identical profiles.
  • the mutual adaptation of the wave profile allows to produce in a simple and reliable way single-flow corrugated board webs whose wave profiles differ only minimally from each other.
  • the small deviation makes it possible, when merging the single-walled corrugated cardboard webs, to connect them geometrically with one another exactly.
  • Precisely placed contact points between the tops of the single-ply corrugated board webs can be generated in this way.
  • Precisely placed contact points between corrugated webs allow material-saving corrugated board architectures to be produced without additional interlayer between the corrugated webs.
  • the method according to the invention is the same for deviations of the parallelism from flooded corrugated cardboard webs.
  • the device according to the invention is designed such that the advantages described above can be achieved in a continuous production process.

  • the wave profile is also aligned parallel to the axis of rotation of the corrugating roll.
  • the gap between a parallel corrugated corrugating roll and its counterpart is insensitive to distortions of the paper web and reliably generates a substantially uniform wave profile when passing through a supplied paper web.

  • the first deflection roller defines the beginning of the convergence region.
  • an outlet may be formed, at which a separation of the first of the second single-walled corrugated board web takes place.
  • the departure in the area of the second deflection roller defines the end of the convergence area.
  • the device according to the invention can be equipped in the region of the merger with at least one steam supply.

  • the device according to the invention can be provided with at least one heating plate, which is arranged for heating at least one single-flow corrugated cardboard web.
  • Heating a single-walled corrugated web reduces its ductility and makes it possible to maintain the mutual adaptation of the corrugated profiles achieved in the convergence zone.
  • shrinkage of the flooded corrugated cardboard webs arises as a result of the heating. Reducing ductility and shrinkage will ensure that the convergence achieved in the convergence area is maintained until the corrugated paperboard webs are joined together. This ensures a high quality of the corrugated cardboard products to be produced.

  • a high-diameter heating cylinder can be used, so that the flooded corrugated cardboard webs are guided along a jacket surface of the heating cylinder with little deformation and thus with little mechanical stress. As a result, distortions or damage to the single-ply corrugated board webs are avoided, so that a high geometric accuracy of the wave profiles is maintained.
  • the heating cylinder may be provided with a roller carrier, in which a first and a second deflection roller are rotatably received.
  • the roller carrier is pivotable about the center of the heating cylinder.
  • the first and the second deflection roller can each form a gap with the lateral surface of the heating cylinder. Such a gap serves to pass through the first and second single-flow corrugated cardboard webs.

  • the convergence region in which the mutual adaptation of the corrugated profiles of the first and second single-walled corrugated fiberboard web takes place, is prolonged.
  • the longer the convergence area the higher the drying effect of the heating cylinder.
  • the higher the production speed is set the lower the drying effect of the heating cylinder.
  • Prolonging the convergence range allows, for example, an increase in the production rate with the same drying effect.
  • increasing the temperature of the heating cylinder allows an increased production speed. A temperature increase is accompanied by increased energy consumption. Setting the length of the convergence range allows the parameters production speed and energy consumption to be freely selected within a wide range of values.
