ABSTRACT:
A combinatorial weighing method and apparatus which operates by weighing plural groups of articles of various weighs by a plurality of weighing machines, finding the sums of all conceivable combinations of these weight values or of given combinations thereof, selecting the combination whose sum is equal or closest to a set value, and discharging the articles from those weighing machines corresponding to the selected combination to obtain articles of a desired weight or number. Between the discharge of the articles from the weighing machines and the following supply of fresh articles to the same weighing machines, an operation of determining the best combination by performing the same combinatorial computations with respect to the weight values of the remaining weighing machines which have not discharged their articles, is performed two or more times to improve weighing capability.
