  • Tubular conveyor belt
    Patent number: 6032789
    Abstract: A tubular conveyor belt and a method for its manufacture, wherein the tubular conveyor belt is composed of a support belt, and wherein the support belt is inseparably connected along both of its longitudinal sides to a drive belt. When constructing the conveyor belt, the drive belts can be placed flat on top of each other, so that the support belt encloses the material being transported. By dividing the tubular conveyor belt into a support belt, on the one hand, and two drive belts at the longitudinal sides, on the other hand, the conveying function is uncoupled from the drive function.
