ABSTRACT:
By providing biasing member in direct controlled biasing engagement with the mesh screen or apertured foil of an electric dry shaver and its cutting blades, a substantially improved and enhanced cutting system is achieved. In this invention, the biasing member continuously provide biasing forces on the mesh screen or apertured foil to maintain the screen or foil in constant contact with the cutting blades of the shaver. As a result, separation of the foil from the blades is virtually eliminated and a substantially enhanced comfort and cutting efficacy is attained.
