<p>A combinatorial weighing method is used for obtaining a batch of articles of different categories, in which the articles in each category are contained in the mixture at a number ratio equal or closest to a target number ratio, which mixture will have a total weight equal or closest to a target weight. The method comprises setting a number for each category of articles so as to provide a number ratio related to a target number ratio, measuring the total weight of a preliminary batch obtained by extracting the set number of articles in each category and mixing these articles, computing the weight shortfall, which is the difference between the total weight of the preliminary batch and the target weight, supplying a plurality of weighing machines with supplemental articles to make up for the shortfall, selecting an optimum combination of weighing machines giving a weight equal or closest to the shortfall, and obtaining a final mixture by discharging supplemental articles from the selected weighing machines and mixing these articles with the primary mixture.</p> |
