This paper describes transporting characteristics of rubber roller feeding a sheet on plain plate for a wide range of velocity (0.5m/s-10m/s). At low velocity, sheet speed (=V_p) exceeds roller speed (=V_r), velocity ratio (=V_p/V_r) is over 1.0, and velocity ratio gradually falls down as roller speed increases. Roller width and rubber hardness degrees increase velocity ratio, and rubber thickness decreased velocity ratio. Also, the magnitude relation of the velocity ratio differed between roller types (united or divided) for urethane roller and polynorbornane roller. When load applied on roller was increased, velocity ratio fell down. The reason for this can be explained by recent researches and it was estimated that the frictional force between sheet and plain plate was large. The reason for the decrease of velocity ratio as the speed increase was discussed. The increase of the speed increases the vertical load and the increase of vertical load leads to decrease of velocity ratio. So, this could be one of the reasons for the decrease of velocity ratio with the speed increase.
