Significant raw material savings, higher quality and better runnability can be easily achieved with the comprehensive headbox maintenance services provided by Valmet.

Or are the dry weight profiles at the optimum level and the flow surfaces clean?

Valmet offers a wide range of professional headbox maintenance and testing services to get the best out of your headbox. These services make it possible to eliminate web streakiness and jet inaccuracy, to lower the need for slice opening adjustments, and to improve dry weight profiles.

By maintaining your headbox better, you can achieve major benefits like:

  • improved dry weight profiles
  • raw material savings
  • better end product quality and production line runnability
  • lower risk of unplanned downtime caused by headbox problems.

Testing reveals the headbox condition

To determine the correct maintenance actions and to reach the optimum headbox performance, it is necessary to know the exact condition of the headbox. Valmet’s in-depth headbox condition tests provide valuable information on the following:

  • slice opening and dry weight profile control and resetting to zero
  • control of the jet impingement
  • headbox functions
  • changes, deformations and damage in the apron and the slice lip
  • condition and cleanliness of the flow surfaces.
