Friction Characteristics Between Paper-Webs and Steel Roller (2nd Report, Experiments)

Abstract

This second report describes the experimental study for friction coefficient between the paper-web and rotating steel roller. The newsprint is used as uncoated paper-web. Euler's belt formula is applied to calculate the friction coefficient form the measured data on tension increase. The measurements are carried out by changing five design parameters such as web width, wrap angle, tension, roller diameter and roller surface velocity. The measured results are compared with the predicted results by the friction model presented in the first report. Good agreement can be seen between the predicted results and measured results.
