RS Material Handling Inc. Narrow Belt Sorters (NBS) have many advantages over more conventional sorters; most importantly, they are designed for quiet operation and maximum efficiency. Features such as:

• several narrow belts instead of one wide belt
• belts running in a track
• elimination of drive mechanisms at divert points
• minimal belt snubbing at 30-degree divert points
• optimum belt tension on each narrow belt with patented automatic belt take-up
• no product-to-roller noise at any divert point

contribute to a sorter so quiet that actual sound pressure measurements are 75% less than those for conventional sorters.
