ABSTRACT:
A beam of light is transmitted from a transmitter (30) which is broken as the moving fiber (22) passes through the beam. A receiver (32) receives the light and generates a signal in response thereto. The signal is processed to determine the status of the pattern generated by the moving fiber (22) of material. In response to changes in the status of the pattern, the rate at which the fiber is dispensed and/or the movement of the pattern can be adjusted as well as alarm conditions noted.
