  • Patent number: 4811833
    Abstract: A conveyor belt comprising an endless belt of a flexible material, and having an upper carrying run and a lower run (1) in which at least one stripper device is provided. The stripper device comprises a frame (2) including a plurality of stripper bars which are mounted on the frame. The stripper bars bear their free edges against the upper face of a run of the conveyor belt, and are formed by a V-shaped bar (4) with relatively short legs (4', 4"). The V-shaped bar has its tip upstream in relation to the direction of movement of the belt. The stripper device also includes a plurality of elongate bars (5, 6) which substantially form extensions of the legs of the V-shaped bar (4). These bars (5, 6) are placed further inwards in relation to the respective legs (4', 4") of the V-shaped bar (4) in such a manner that neighbouring ends of the legs of the V-shaped bar and of the elongate bars overlap.
