Abstract

The differential velocity of paper feeding rollers is controlled by a tension gearing system with a ring gear and tension wheel used as driving and driven components, while the motion is determined by a magnetic powder brake. The motion is transmitted by bevel gear driving the auxiliary shaft of the pulling rollers, while the tension wheel carries the ring gear. The number of teeth in the latter exceeds the teeth number of the wheel and the magnetic powder brake is fitted at the end of stub shaft. The ring gear may have inner toothing and may have reduction gear train connected.
