Dry-shaving apparatus with hair-pulling lead cutters

A dry-shaving apparatus which comprises a casing provided with a skin-guide member and a shear-cutting member having a cutting edge, a longitudinally extending slot-like helical hair-entrance aperture being formed between said two members, a cutter roller rotatable about a spindle longitudinally mounted in said casing, means to rotate said cutter roller about said spindle, said cutter roller having a plurality of radially extending shaving cutters each having a cutting edge parallel to the axis of the cutter roller, the respective cutting edges of said shaving cutters successively engaging the cutting edge of the shear-cutting member as the cutter roller is rotated, and a generally U-shaped flexible lead cutter positioned between each pair of shaving cutters and opening radially outwardly, one leg of said U-shaped lead cutter being attached to the preceding shaving cutter in the direction of rotation and the other leg having a cutter edge and being resiliently supported by the succeeding shaving cutter for radial inward movement upon engagement of a hair protruding through said hair-entrance aperture by the cutting edge of said other leg.
