ABSTRACT:
The invention is directed to a long-hair trimming device for dry shaving apparatus, with a cutting comb arranged fast with a housing and having an abutment surface for engagement with an abutment surface of a cutting blade which is coupled to a carrier body via at least one driving member, the carrier body being adapted to be driven by a drive means, and with at least one pressure spring bearing with one end against the carrier body while its other end takes support upon the housing, wherein the carrier body provides on the side close to the cutting teeth of the cutting blade a slightly protruding seating edge made of a plastics material and having its cross-sectional profile tapering in the direction of the cutting blade, wherein the seating edge rests against the cutting blade in the area of the root of the cutting teeth, and wherein an optimum abutting engagement of the cutting blade with the cutting comb is accomplished by deformation of the seating edge and the cutting blade by means of the force the pressure spring exerts through the carrier body on the seating edge and on the cutting blade.
