Abstract

A twin-belt band conveyor in which the flat belt of an endlessly circulating conveyor band forms a closed conveying space with a belt of a cover band running along therewith on a steep conveying track, the edges of each belt being held in superimposed arrangement by guides along the longitudinal sides of the conveying space, the conveying space (34, 50) being formed by indentations of at least one of the belts between the guide, and opened at the end of the steep track by a deflection of the cover band directed around a turn, and the indented belt being straightened out for its return travel. The cover band belt (2) has tensile reinforcements disposed in its longitudinal sides and transverse reinforcements which cooperate with the tensile reinforcements are provided in the cover band, the indentations and straightened out areas (32 to 34) being formed between the transverse reinforcements and the tensile reinforcements, and the belt of the conveyor band limiting the conveying space is held flat on the steep track and the guides of the upwardly moving belt strands are of continuous design.
