  • Flexible contour sanding disc
    Patent number: 5584754
    Abstract: An improved star head sanding assembly for sanding on the peripheral edges of the individual abrasive discs. The discs are provided with radially arranged non-parallel skip cuts, and are devoid of radial cutout sections to provide maximum peripheral surface area. During use, the free edges of the individual fingers tend to twist through substantially a right angle to present a line contact with the workpiece surface at least partially perpendicular to the direction of movement of the assembly relative to the workpiece.
