  • Self-adjusting feed stock accumulator system
    Patent number: 5622330
    Abstract: A system for controlling the feed rate of a feed stock to processing equipment by monitoring and controlling the length of the feed stock in an accumulator assembly. The control system regulates the feed rate of the feed stock by initially forming a line of the feed stock in the accumulator assembly, detecting the extent of the length of the line with respect to preselected set points, controlling the length of the line in the accumulator assembly by adjusting the feed rate of the feed stock from a base feed rate in response to preselected minimum and maximum values for the length of the feed stock line, and adjusting the base feed rate with each excursion of the line from the preselected minimum and maximums.
