Abstract
A quantity of material contained in a bank between a pair of calendering rolls is determined by digital imaging technology. Manipulation of digital images provided by a camera yields a light-hued image of material in the bank against a dark-hued background. The light-hued image is then divided into control zones associated with discrete regions of the bank fed by separate feed lines. Quantity and distribution of material in the bank can be controlled by adjusting feed rates based on information obtained through the digital images.
