Abstract
A weighing system for making up two discrete quantities of solid product, each having a preferred product weight, from a plurality of product holding chambers, without refilling such product holding chambers. Each weighing scale is efficiently used in every machine cycle. Source product is divided into a plurality of smaller quantities which are a fraction of the target weight. Each of the fractional weight quantities becomes part of a set for which all possible double discharge fractional weight combinations are determined. The first combination capable of providing two acceptable discharges of the target weight, or the preferred weight closest to the target weight, is selected. Thus, two packages are efficiently delivered for each scale cycle. Efficiency of scale usage is assured by ordered selection of the holding chambers from which the discharges are made.
