ABSTRACT:
In a conveyor for conveying articles in a helically curved path, an endless conveyor belt is driven in a helically curved path between the circumferential surface of a cylindrical envelope and a rotary drum coaxially arranged in the envelope. One edge of the conveyor belt is supported by the circumferential surface of the envelope while the other edge of the conveyor belt is engaged between consecutive convolutions of an entraining belt which is passed around and driven by the drum at the rotation thereof so as to carry along the conveyor belt in its movement.
