ABSTRACT OF THE DISCLOSURE A tubular belt conveyor is provided herein having an endless belt and a novel belt-pressing device associated therewith. The belt-pressing devise includes a plurality of spaced-apart supporting frames, each of which is disposed to surround outgoing and returning paths of the endless belt. A plurality of closely- spaced, belt-shape-maintaining rollers, are arranged to configure substantially a circle inside each of the supporting frames. A belt pressing roller, disposed adjacent a conveyor loading station at one end of the conveyor between the station and the nearest supporting frame pressedly bends one side end portion of the endless belt horizontally inwardly and beneath the other side end portion, the belt-pressing roller thus reducing frictional contact between one side end portion and the other side end portion as the side end portions move laterally relative to each other during formation of the overlap by being positioned between the one side end portion and the other side end portion, where the endless belt is to be rolled horizontally into the overlapped tubular shape. The belt-pressing roller is adjustable laterally of the belt and vertically, the belt-pressing roller extending in a substantially-horizontal direction laterally of the belt over the outgoing path of the endless belt on an upper side of the belt. A receptacle finally is provided to receive the materials carried adjacent the end of the outgoing path.
