ABSTRACT:
A high speed, normally closed tubular belt conveyor system operable over long distances and through relatively short radius horizontal and vertical turns. The belt conveyor is prestressed at fabrication to provide a normally closed tubular configuration. Profiled end pulleys are provided which open the belt for loading and unloading with minimum strain and distortion. A distributive drive system provides reduced longitudinal tensile stresses in the belt and facilitates high speed operation. A feeder-accelerator system loads granular-type material into the tubular belt at a rate and velocity which are conformed to the capacity and velocity of the belt.
