Abstract
A method of operating an article sorting machine automatically adjusts weight cutoff values defining size grades to compensate for variations in weight distribution of the articles. The method comprises the steps of monitoring the actual average weight of the articles classified into each size grade, periodically comparing the actual average weight of the articles classified into each size grade to values indicative of the desired average weight of the articles classified into each size grade, and modifying ones of the weight cutoff values if the actual average weight of the articles classified into selected ones of the size grades differs from the desired average weight of the articles to be classified into the selected ones of the size grades.
