DynaCoat

Brilliant coating quality

    Highest surface smoothness with blade coating

    The DynaCoat is a direct coating unit mainly used for blade coating. The accurate technology of DynaCoat provides the highest surface smoothness and most excellent gloss values of all coating methods.

    The core of the DynaCoat is a smart blade beam design, which eliminates thermal influences and provides a consistent uniform CD profile. Coating blades in stiff blade and bent blade mode can be used for the highest surface smoothness, and a smooth metering rod can be used for leveling.

    Multiple features – like the contactless free-jet application, police filter to prevent plugging of the color jet, and protection against dry running blades – ensure smooth conditions for blade coating for best runability.

    The DynaCoat concept includes an operator-friendly operation and maintenance concept with automation support. Together with the clean design, efficient production and reduced maintenance time are realized.

    Your benefits with DynaCoat

    • Brilliant coating quality with highest surface smoothness
    • Consistent uniform CD profiles
    • High operational reliability for improved paper machine runability
    • Operator-friendly design for easy operation and service

    3 - Color application to the sheet
    4 - Blade beam
    5 - Coating blade
    6 - Backing roll
    7 - Color return channel

    Functional principle

    The accurate technology of DynaCoat provides the highest surface smoothness and most excellent gloss values of all coating methods.

     

    Comparison of coating methods

    Contour coating offers variable reflection properties and does not improve gloss.

    In contrast, DynaCoat offers mirror reflection properties through leveling coating with blade.

    Select your DynaCoat configuration

      Thanks to the modular concept, DynaCoat offers a variety of configuration options. Each blade coater is optimally tailored to your individual requirements. To give you an overview, we have selected two typical design examples.

      Reliable coater with excellent cost/performance ratio

      • Proven, robust roll applicator
      • Smart blade beam design for good CD profiles – no water circulation system needed
      • Tube loading and tube clamping for reliable blade operation
      • Modern maintenance and operator concept

      This configuration shows a typical setup for board grades with a production speed up to 800 m/min.

      Top-of-the-line coater

      • JetFlow F free-jet applicator for uniform color application and improved runability
      • Carbon fiber blade beam in combination with smart design for best CD profiles
      • Mechanical blade clamping and loading for the highest precision in blade coating
      • Operator-friendly design for easy operation and service
      • Option for MD coat weight control (DynaBlade C) and for CD coat weight control (ModuleCoat)

      This configuration shows a typical setup for graphical and specialty grades with high production speed.
