Coating

Choosing the right blade option is key to consistent coating quality and maximum machine uptime.

Designed for distinct paper mill requirements, our T- and C-surface layers protect both your blade and equipment from premature wear.

Coating products

  • Engineered for high-speed paper machines in demanding pre-coat and top-coat positions.

  • Developed for low-to-medium-speed paper coating applications in the top-coat position and improves the coated paper quality.

Higher productivity

Less blade wear means fewer unscheduled stops and smooth, uninterrupted machine runs.

Improved paper quality

Consistent blade profiles ensure even coating application and fewer surface defects.

Reliable blade protection

Precise blade contact protects delicate coating structures and ensures a uniform surface finish.

  • The edge protection ensures that the coating of the product remains fully protected until it is used on the machine and reduces the risk of injury for workers.

  • Custom coating blades ensure a smooth, uniform coat application—delivering superior surface smoothness, optimal printability, and maximum runnability on the paper machine.

  • Extended blade lifespans and precise doctoring minimize web breaks and paper waste—saving energy, conserving raw materials, and advancing your sustainability goals.

  • Advanced carbide technology resists erosion and edge wear in demanding coating applications, ensuring long-lasting edge sharpness, uniform coat weight, and reliable high-speed results.
