<p>TUBE BELT CONVEYOR The present invention concerns a tube belt conveyor in which a flat belt (1) is like a helically seamed tube at least over the length of its transporting part. Tubularity of the belt (1) has been achieved by winding the flat belt helically to be tubular about its longitudinal axis and by disposing the helically seamed tube between the bending drum (3) and traction drum (5) of the conveyor. The helical configuration is produced and maintained by the aid of roller sets (7 and 9). In the helically seamed tube belt it is possible, if desired, to make bends by means of bending roller sets (8). It is possible to transport material with the tube belt conveyor in different planes between the horizontal plane and the vertical plane.</p> |
