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
