  • Patent number: 6684508
    Abstract: A shaving head comprises a cutting member a hair manipulator. The cutting member has a cutting edge which extends in a direction perpendicular to a shaving direction of the shaving head. The hair manipulator is arranged in front of the cutting edge, seen in the shaving direction, and can be driven in a direction parallel to the cutting edge. Hairs trapped by the hair manipulator are moved along the cutting edge while being cut, so that the cutting forces in the shaving direction are reduced. The cutting member can also be driven in a direction parallel to the cutting edge such that, seen in this direction, the cutting member and the hair manipulator move in opposite directions for a longer period of time than in equal directions. In this manner the cutting member has a stretching effect on the skin present immediately in front of the cutting edge, and said stretching effect of the cutting member intensifies a similar stretching effect of the hair manipulator.
