ABSTRACT:
A system and process for measuring paper formation characteristics in real time is disclosed. The system comprises apparatus used in a papermaking process, and includes a rotating forming fabric having an upper and lower surface. A paper slurry is deposited upon the upper surface of the moving forming fabric to prepare a wet paper web. The wet paper web typically moves at a high rate of speed as it rides along upon the surface of the forming fabric. Light is transmitted from a light source to the surface of the wet paper web, and then reflected from the surface of the wet paper web to a camera. An image is formed corresponding to the pattern of the reflected light, and in some instances data generated from the reflected light may be compared to other values to provide a feedback loop to adjust the parameters of the papermaking process in real time.
