A rubber roller with tactual sensor is developed experimentally for a reliable paper feed of paper handling devices. The condition of contact between the roller and the feeded paper is monitored by using a piezoelectric element mounted in the roller. The features of the monitored signal are analyzed and this enables to disinguish the paper feeding from the slip of the roller or the paper. The motion of paper feeded by the roller is simulated by the finite element method and the results also certify the possibility.
