Abstract: An easily-cleaned, rubberized conveyor assembly especially adapted for conveying granular or semi-fluid material. The present invention is particularly concerned with conveying food materials where cleaning and sanitary conditions are important. The invention is also particularly described with regard to a conveyor for the bottom of a holding or surge bin, but has other applications. In the invention, upright side guards along opposite sides of a continuous rubberized belt separate the belt into a central load-carrying portion and outer edge aligned portions. Connections connect the edge aligned portions to supporting girts beneath the belt, the girts in turn being attached to endless conveyor chains on opposite sides of the belt. Preferably, the side guards are rubberized elements vulcanized to the belt surface, thereby providing an assembly having a load-carrying area free of cracks or crevices.
