ABSTRACT:
A combinatorial weighing method and apparatus for obtaining a batch of articles of a plurality of categories, each category of articles in the batch having a predetermined weight or made up of a predetermined number of articles. The method includes the steps of setting a target value for each category of articles, and supplying a plurality of weighing machines, groups of which are provided for each category of articles, with the articles of the category corresponding thereto. For each category of articles and from all combinations is selected, of the weighing machines supplied with the category of articles, a best combination whose total value (weight or number) is equal to the target value set for that category or closest to the target value within preset allowable limits. Then, the articles from those weighing machines corresponding to the best combination obtained for each category of articles, is discharged so that a batch composed of the discharged articles, is obtained.
