Abstract: A feed control system for a plurality of packaging machines is provided wherein the overall supply to the machines is controlled in accordance with total demand. A pulse is produced by each machine after a filling and sealing operation is completed and a weight constant multiplier is employed to multiply this pulse by a weight constant associated with the package (the number of grams or ounces contained in the package). The outputs of all of the weight constant multipliers are connected to a parallel to series converter which produces a signal in the form of a pulse train representative of the total weight requirements of all packaging machines per unit time. This signal is converted into a corresponding voltage level which is utilized by a storage conveyor motor controller to control the overall feed rate to the machines.
