Major benefits by maintaining your headbox


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.
