ABSTRACT OF THE DISCLOSURE An elevator-conveyor for conveying bulk material over a predetermined path, at least a portion of which path is in a vertical or near vertical direction. The conveyor comprises a pair of juxtaposed belts between which the bulk material is to be located and air pressure means adapted to act directly on one or both of the outer belt surfaces when the belts are in the vertical or near vertical direction so that the belts are pressed towards one another and against the interposed bulk material so as to enclose the same and so that the juxtaposed longitudinal edge portions of the belts are pressed against each other. The improvement resides in that a terminal portion of the elevator-conveyor is designed to be located in the vertical or near vertical direction and comprises oppositely facing sub- stantially straight terminal portions of the belts disposed at an acute angle with respect to each other and defining there- between a substantially wedge shaped feed zone. The angle is not greater than that which allows entrainment of the material therein. The zone opens outwardly from a position where they are substantially in contact towards a feed end of the conveyor. The straight terminal portions have lengths substantially greater than the maximum thickness of the feed zone. A feed mechanism is also provided for gathering and projecting the bulk material into the feed zone.
