ABSTRACT:
A machine for sorting rod-shaped articles 3-6 of magnetic material in accordance with their respective lengths, such as knives, forks, and spoons, includes a transporting arrangement 1 which comprises magnetic collecting rods 2 which attract magnetically the ends of respective items and carry them past a plurality of underlying magnetic delivery rods 11-14 with the items hanging vertically. The delivery rods are spaced at a progressively diminishing distance from the movement path of the collecting rods so that the lower ends of the longest items 3 come into contact with the first delivery rod 11 and are drawn loose from a collecting rod 2 thereby, this procedure being repeated at each classifying station until the shortest item 6 comes into contact with the last, commensurately spaced delivery rod 14 and is drawn loose thereby.
