Title:
METHOD FOR FORMING RAZOR HEAD OF DRY RAZOR
Document Type and Number:
Japanese Patent JPS62170285
Kind Code:
A
Abstract:
A method for making the shaving head of a dry-shaving apparatus with an effective shaving area of a desired shape, in which a shear foil is mounted in an arcuate condition in a shaving-head frame without the cutter so that the foil assumes a free clamping curvature which is not influenced by the cutter, a normal-pressure distribution is applied perpendicular to the foil curvature which simulates the pressure distribution between the cutter and the foil in conformity with a desired effective shaving area, so that the shear foil experiences in said effective shaving area a deformation relative to the free clamping curvature, the simulated pretension curvature thus obtained corresponding to the desired normal-pressure distribution on the cutter in the desired effective shaving area relative to the shear foil. The cutting edges of the cutter are curved in conformity with the pretension curvature of the shear foil thus determined and the cutter, whose shape is in conformity with said pretension curvature, is pressed into the shear foil with the force which provides the desired normal-pressure distribution.
