Gillette has experienced problems with noise, vibration, and wear in their current blade cutting cam. Our redesign eliminates the expensive 3D track cam and replaces it with a less expensive and easier to manufacture 2D track cam. The cutter mechanism stays the same, but is now actuated by a four bar slider-crank linkage that is driven by the new 2D cam. A spring-loaded connecting rod that elongates when the blade break impact occurs provides controlled compliance and limits blade impact forces. The new design allows a precise and repeatable cutting force to be applied to the blade strips, while reducing the noise, vibration and wear in the system.
