ABSTRACT:
A unique one-piece disposable clipper head is characterized by the provision of a synthetic plastic base molded as a unitary structure about two metal cutting blades which are integrally formed with the base during an insertion molding process. The base includes a fixed portion with which the lower cutting blade is integrally formed and a movable portion with which the upper cutting blade is integrally formed. The upper movable portion and the lower fixed portion of the base are initially formed as a unitary structure. Following molding of the base, the movable portion is separated from the fixed portion to afford horizontal or lateral displacement of the movable portion and the upper blade relative to the fixed base portion and the lower blade. The base contains a recess in the bottom surface thereof for receiving the clamping mechanism of an electric clipper for attachment thereto. The base also includes on its upper surface in addition to the movable portion a plurality of projections for alignment and connection with the drive mechanism of the clipper. The metal cutting blades each have a planar configuration and are arranged in contiguous parallel relation, and both include a forward toothed edge arranged adjacent one another. When the clipper is turned on, the clipper drive mechanism laterally displaces the movable portion and the second blade relative to the first blade, whereby hair arranged between the toothed forward edges of the fixed and movable blades is cut.
