Latest Patents

Ralph E. James holds a patent for a "High Flap Density Abrasive Flap Wheel." This invention features an improved abrasive flap wheel that consists of a highly compacted annulus of like-oriented, radially disposed, interleaved coated abrasive flaps and resilient, lofty, non-woven flaps that are adhesively fastened together at their adjacent inner ends. The manufacturing process involves compressing a stack of juxtaposed flaps to form a block that matches the inner perimeter of the annulus. The ends of the flaps are fastened together, and the block is shaped into an annulus with the free ends of the flaps directed radially outward. The compacted flap wheel demonstrates a much higher abrasive grain efficiency compared to conventional flap wheels.
