This paper describes a frictional characteristics of rubber rollers for a wide range of transport velocity (0.01〜10[m/s]) which covers almost every paper handling in office automation and in banking systems equipment. Frictional coefficients of rubber roller and paper sheet slightly decreases at high velocity and decreases at low velocity. We have also examined the differences of frictional characteristics among three types of experiments. We have found out that the frictional coefficient at low velocity differs with system of experiments, whether roller-fixed or roller-rotated. We have simulated these systems by non-linear finite element analysis. As a result, stick-slip seemed to have occurred at low velocity range. Roller-rotated is more affected by stick-slip and the frictional coefficient at low velocity is smaller than roller-fixed.
