<p>A modular plastic conveyor belt is designed to turn a tight radius in one direction only. Particularly it is designed for use as a spiral conveyor belt, the belt can turn in the opposite direction, but with a much larger radius. At the outer edge of the belt, the link ends or knuckles are larger and heavier for increased strength in accepting tension at the outer edge of the belt. The outside knuckles or link ends are not only wider than at the inside, but they also are longer, with increased material beyond the rod opening for increased tension strength. By having wider link members at the inner edge, the belt can collapse more closely at the inner edge than would be possible if the turn were in the other direction, providing a tighter radius of turn. This is useful in spiral conveyors which ordinarily turn in only one direction through the entire path of travel.</p> |
