ABSTRACT:
Apparatus for cleaning endless abrasive belts utilized for sanding and grinding operations, wherein substantially the entire belt is enclosed within a shroud and wherein intermittent blasts of compressed gaseous fluid are directed onto the surface of the belt as it traverses its orbital path. Specifically, the compressed gas is directed onto the surface of the belt within the shroud and at a point wherein the belt is wrapped about the surface of the roller, which opens the grid pattern slightly. The intermittent utilization of compressed gaseous fluid utilizes a substantially lower volume of compressed fluid than would be required on a continuous basis, and furthermore the arrangement has been found to clean the surfaces of abrasive belts more effectively than can be accomplished with a continuous discharge. The shroud which encloses substantially the entire length of the endless abrasive belt reduces dust discharge.
