Abstract

This thesis is the third in a series of fundamental investigations of the variables of supercalendering. The variables studied in this thesis are the internal effects derived from rolling pressure and of static pressure on paper. These variables were investigated by testing four grades of paper after being subjected to supercalendering and comparing them with similar grades pressed by a hydraulic press. The experimental results show that a definite comparative trend in the internal effects of paper were established between the rolling pressure caused by supercalendering and static pressure given by a hydraulic press. The physical properties tested were Mullen, Opacity and Caliper. The only exception to the comparative trend established were the results obtained from the tests of a ground wood sheet.
