Abstract

A viscous material processing system comprises a feed system controller having a set of instructions to store an input set point weight or amount; sense a progressing weight or amount of material fed by the feed system; compare the progressing weight with the set point weight or amount and terminate feed from the system when the compared progressing weight is substantially equal to the set point weight or amount; and a viscous material compounding system connected to the feed system to receive material fed by the feed system.
