Abstract
A method and apparatus for preparing a blended product charge includes a combinatorial weigher which receives a major product and a fill-to-cutoff weigher which receives a minor product. A controller selects a minor constituent product weight and then combinatorially searches through available major constituent product weighing scales for the combination of major product weighing scales which together with the minor product weighing scale yields a product charge nearest in weight to a target weight.
