This paper describes the measurements of traction coefficient between paper-web and steel roller under various operation conditions. The uncoated paper (newsprint) is used as test web. In the measurements, the web is wrapped over the rotating roller with the surface velocities from 0 to 40 m/s. The web tension is applied by the weight at the edge of web and the traction force between web and roller is measured by the load-cell at the other edge of the web. The traction coefficients are, then, obtained based on the Euler's belt theory. Two types of grooved steel roller are used, and the web-wrap angle, web tension, web width, roller diameter are changed as operation parameters. From the measured results, the effects of such various operation parameters on the traction coefficient between web and grooved roller are clarified.
