20104-8216 ABSTRACT The invention relates to a method of providing the shaving head of a dry-shaving apparatus with an effective shaving area of a desired shape in accordance with its use, in which a shear foil is mounted in an arcuate condition under pretension in a shaving-head frame so as to be movable at the clamping locations. A cutter is pressed into the curved portion of the shear foil, which cutter also has curved cutting edges, the tangent lines to the clamping curve at the clamping locations extending at an acute angle to each other. The method is characterized by the steps of: initially clamping the shear foil without the cutter at a pre- selected angle, with a pre-selected length and at a pre-selected distance; subsequently, in addition to the clamping curvature which is not yet influenced by the cutter, a no-load normal-pressure distribution perpendicular to the foil curvature is simulated be- tween the cutter and the foil in conformity with a desired effec- tive shaving area, so that in addition to its curvature depending on this desired form of the normal-pressure distribution the shear foil. experiences in said effective shaving area a simulated deformation relative to the free clamping curvature, the simulated pretension curvature thus obtained corresponds to the desired normal-pressure distribution on the cutter (in the desired effec- tive shaving area) relative to the shear foil. The cutting edges of the cutter are curved in conformity with the pretension curva- ture 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 clamping curvature with the force which provides the desired normal-pressure distribution.
