TENSION

An incorrect tension in dryer fabrics influences the drying efficiency, the surface quality of the sheet and the runnability of the dryer section.

  • poor heat transfer and matching drying efficiency due to slack fabrics
  • uneven CMD tension = uneven permeability = uneven sheet moisture profile
  • ‘orange peel’ defects in coated paper, caused by too taut or slack fabrics
  • unstable dimensions – for example canvas becoming too narrow or wide
  • bearing and roll failure due to unexpected high tension
  • only correctly tensioned fabrics transfer drive power to the non-driven cylinders while not damaging the web
