Abstract
A belt conveyor comprises a drum, which is rotatably mounted on a vertical center shaft (4'), and an endless conveyor belt, which along part of its length follows a helical path through several turns around the drum and in contact with the outside of the drum. The drum has a plurality of vertical strips (10), which are distributed around the outside of the drum, engage the conveyor belt through the majority of the turns thereof and are each vertically movable from a starting position in one direction together with the belt through essentially one rotation of the drum and are then successively returnable vertically in the opposite direction to the starting position.
