With Rack To Drive Cutter Patents (Class 409/335)
  • Patent number: 5211517
    Abstract: This invention describes a machine for the manufacture of small grooves in metal edge inserts typically found on the undersurface of snow skis. The machine produces ice-cutting blades by cutting grooves of approximate uniform depth a constant distance from the edge of the snow ski. With a ski positioned and secured with mounting clamps 21 so that a metal ski edge extends beyond a machine platten 10, a plurality of flattening clamps 23 flatten the typically bowed ski against a flat undersurface 22 of the machine platten 10. A cutting tool on a tool holder slidably mounted to a slide means on the platten upper surface then cuts into the metal ski edge following the curvature of the ski edge as it traverses the ski.
