Abstract: A method and apparatus for cleaning abrasive belts of the type used in belt sanding operations. The apparatus includes a module having a frame composed of abradable side wall members. A block of cleaning material of natural or synthetic rubber is contained within the frame and engages the belt surface. The module is supported on a resilient base which is slightly compressible as the module passes through the belt sander to exert a uniform continuous biasing force on the belt surface to be cleaned as the module and belt are moved relative to one another.
