Abstract

Measurement of the gap between a cylindricall roll and another cylinder or flat surface by placing in contact with the roll surfaces on both sides of the nip contact feet which are a known distance apart laterally and then measuring the distance between the contact feet on opposing surfaces on the same side of the nip. The size of the gap may be solved by geometrical analysis. The method is used e.g. for measuring the gap between calender or mill rolls. Provides a direct measurement of the without involving the die swell effect which requires correction if the gap is determined indirectly by measuring the thickness of material passed through the nip.
