Patent number: 5662515Abstract: A profiled, soft cushioned roller is provided with an outer profiled abrading surface that conforms to and rides on a contoured substrate surface during an abrading operation. A soft roller usually in the form of a soft foam layer or body allows the profiled abrading surface to extend to and laterally wrap itself along the contoured substrate surface when pushed against the latter with the force needed to abrade the contoured surface. Because the outer surface portion of the profiled, soft roller is able to distort and wrap across the contoured surface, the soft profiled portion need not have the exact contoured shape and dimensions of the contoured surface being abraded. The soft roller body may have portions with different hardness by using different materials or different densities of the same foam material.Type: GrantFiled: April 17, 1996Date of Patent: September 2, 1997Inventor: Kenneth Evensen
