Main Applications

Komori-Chambon expertise

  • Stability at high speeds

     

    Outstanding mechanical sturdiness.

    Best printing stability at highest speed.

    Max speed 500 m/mn (roll to roll).

  • Maximum OEE

     

    Automated job parameters and low maintenance increase the operating time and the ease of use.

  • Ease of use 

     

    The printing units can host OEM gravure cylinders.

    They include pre-washing, anti-splash and solvent odour control devices.

  • Profitability

     

    Energy saving, waste reduction and high speed boost productivity and profitability

Production flow insights

  • The plate cylinder is engraved via an electromechanical process, or in laser.
  • The depth of cells is adapted to the target color density and the related quantity of ink needed.
  • The engraving precision varies from 500 dpi (conventional) to 5080 dpi (laser).
  • For extended runs, the plate cylinder is chrome-plated.

 

  • The make-ready operations are very simple and quickly realized.
  • Being a direct printing process, the construction of a printing unit comprises only two key elements: a gravure cylinder and an impression cylinder.
  • The inking cassette is smoothly introduced in the unit thanks to a trolley or a simple pallet truck.
  • Automatic pre-settings.

 

  • The ink flow is controlled via a pneumatically assisted ink roller.
  • An optional pre-inking roller helps fine-tune the flow depending on the ink type or the production speed.
  • The printing quality is ensured by the easily adjustable doctor blade (offline) which will remove any excessive ink on the gravure cylinder.
  • The number of printing units is adapted to the required special colors and to the added value steps (coating, holograms, metallic inks…).

 

  • Air temperature control and optimized air/solvent ratio.
  • Choice between thermal oil, steam or electrical heater.
  • New generation nozzles for boosted efficiency up to 500 m/mn.
  • UV curing available for added value steps

 

  • Many added value operations can be proceeded, such as foils and holograms in one pass.
  • Flexo or offset units can be added either for varnishes or variable design details.
  • The reverse printing is possible in gravure as an option.

 

  • Easy and quick change of gravure cylinder.
  • Sleeve impression cylinder for a fast changeover (ESA).
  • Quick offline job change (10 minutes).
  • Doctor blade replacement without pulling the cassette out.
  • One-touch gravure cylinder pre-washing system.

Available configurations

ROLL TO ROLL

 

The press includes a rewinder right after the printing units.

The converting stage will be proceeded offline.

For more flexibility, the line can include a rotary die-cutter and a by-pass to transfer the web to the rewinder.

 

ROLL TO BLANKS

 

The best configuration to take the maximum profit of your production line.

The inline rotary die-cutter, placed right after the printing stage, can be followed by a high speed delivery solution.

The carton roll is transformed into ready-to-ship blanks within 10 seconds.

 

ROLL TO SHEETS

 

The printed web can be converted in sheets thanks to a slitter.

The sheets can be converted offline with a flat bed die cutter.
