A weighing system for making a predetermined weight of a product comprised of individual articles having variable weights by selecting the product stored in a combination of a predetermined number of storage cups. Quantities of the product having targeted weights are distributed to a plurality of scale-controlled hoppers for accurate weighing. The weighed product is fed from each of the scale-controlled hoppers to a plurality of storage cups associted with each of the hopers, and the product weight associated with each storage cup is registered. Specific combinations of storage cups are tested to determine whether the combined product weights therein add to make the desired weight, within acceptable limits. The first combination found to make the weight is used, and the appropriate storage cups are emptied to a container for receiving the product. The appropriate storage cups are refilled from the scale, and the process repeats. When none of the combinations of the preselected number of storage cups include a total product weight within the acceptable limits, the limits are broadened and the cycle repeats. The weighing system includes a programmed microprocessor for controlling operation thereof, for providing the combination to be tested, for calculating the combined weights, and for determining whether the combined weight falls within the acceptable limits. A specific distributor for the product includes a reversing rotating portion for preventing clogging of the product at openings provided for chutes connecting the distributor to the scale-controlled hoppers.
