Abstract
A reversible belt scraper blade provides two opposed scraping surfaces on an integrally constructed body. Each scraping surface has an elastomeric wear region transitioning to an elastomeric central region. Two integral frame members are integrally joined into the central region. Each integral frame member runs the length of the belt scraper blade and is at least partially exposed at their ends. End mounts attach to the exposed integral frame members and the reversible belt scraper blade is reversible about the end mounts. The wear regions may have sub-regions of different hardness to provide good scraping qualities combined with improved structural rigidity. The central region may also have sub-regions of different hardness to improve structural rigidity.
