Results

Bottlenecks removed in the paper machine wet end:

  • More constant and flatter grammage variation in both machine and cross direction: CD deviation reduced more than 15%
  • Tensile strenght index reduced by more than 50%
  • Increased machine efficiency, because less time is lost on grade and grammage changes, and the PM 34 now operates at a more constant level because of the higher automation level.
  • The mill crew has been able to assess the right color level needed for each customer more quickly.
  • The flatter sheet also helps with changes in color constancy: A more constant sheet means a more constant color level.
