ABSTRACT:
A device for sensing speed and angular position of a web of newprint in a continuous feed press. A stator includes an optical source and an optical sensor. A rotor has an aperture of predetermined size and position which is operative as a shutter to block and unblock the optical path between the optical source and sensor. The device provides a speed and position signals without commutator contacts which are subject to rapid wear and which require frequent maintenance.
