OPEN CUTTER FOR A FOIL TYPE SHAVER AND METHOD FOR FABRICATING THE OPEN CUTTER

摘要

An open cutter for a foil type shaver includes a plurality of arch-shaped cutting strips formed by bending a metal plate formed with alternating parallel slots and cutting strips. A plurality of spaced apart protruding cutting edges having a first acute cutting angle is formed along two opposite sides of the cutting strips. A plurality of recessed cutting edges having a second acute cutting angle is formed between the plurality of protruding cutting edges. The protruding cutting edges of one cutting strip are facing the recessed cutting edges of an adjacent cutting strip, thereby generating continuous hair-lifting and hair-cutting actions as the open cutter is driven in oscillating directions by a motor. A method for fabricating the open cutter is also disclosed.

主权项

1. An open cutter for a foil type shaver, the open cutter comprising:
(a) a plurality of arch-shaped cutting strips formed by bending a metal plate formed with alternating parallel slots and cutting strips, each arch-shaped cutting strip having two opposite sides and a top surface in sliding contact with an underneath surface of an arcuate foil through which hair to be cut can pass; (b) a plurality of protruding cutting edges formed along the two opposite sides of the arch-shaped cutting strips and spaced apart from each other, each protruding cutting edge being defined by an extension of the top surface of the cutting strip and a bottom surface inclined at a first acute angle with respect to the extension of the top surface; and (c) a plurality of recessed cutting edges defined by the plurality of protruding cutting edges, each recessed cutting edge being defined by the top surface of the cutting strip and the side of the cutting strip inclined at a second acute angle with respect to the top surface; (d) wherein the protruding cutting edges of one cutting strip are facing the recessed cutting edges of an adjacent cutting strip, thereby generating continuous hair-lifting and hair-cutting actions as the open cutter is driven in oscillating directions by a motor.
