Patent Number: 6,308,824

Title: Tube conveyor

Abstract: A tube conveyor, in particular a tube conveyor in which an endlessly revolving conveying belt is guided at least partly in the interior of carrier rolls (5) which are attached in a ring-shaped manner and whose axes extend substantially transversally to the direction of conveyance, and is substantially shaped into a tube, with the return of the conveying belt (3) being performed outside of the loaded strand shaped into a tube. In order to provide a tube conveyor which does not require any additional external supporting rolls for the return of the unloaded strand and thus both simplifies the installation of such a tube conveyor and reduces its noise production during operation, the return of the unloaded strand (9) of the conveying belt (3) is performed while resting on the upper carrier rolls (5) which are arranged in a ring-shaped manner.
