Abstract: A product filling system (100) includes a first multi-lane conveyor (106) for receiving products and a second multi-lane conveyor (110) for receiving the products from the first multi-lane conveyor (106). The first multi-lane conveyor (106) and the second multi-lane conveyor (110) include a plurality of independently movable belts controlled by a controller (128).
