ABSTRACT:
A method and a system for classifying a plurality of random length boards of random grade, using a conveyer provided with reading units to read both the length and the grade of each board at a first end of said conveyer; a processor, receiving length and grade data from the reading units; calculating combinations of board lengths and grades and selecting a preferred combination of boards from the combinations; and a distribution section, located at a second end of the conveyer, and operated by the processor according to the preferred combination; the processor being fed with a large number of identified boards, from which to calculate the combinations of board lengths and grades, before they reach the distribution section.
