Abstract

Articulated decline belt conveyor in which the elbow is defined by a pair of rollers respectively attached to the joined sections of the frame for dividing the decline angle into two smaller parts. The belt is transversely troughed over much of its length, but is flattened by the pair of rollers defining the elbow, thereby permitting a more substantial decline angle than if the belt was transversely troughed while traversing the elbow. Improved structures for supporting the conveyor frame are also disclosed.
