IPC: B26B19/04
Filed: 1987-01-14
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.

Filed: 1982-01-14
Abstract: PURPOSE:To simplify the structure of a laminated electromagnet iron core and to obtain a small-sized iron core having no adhesion by providing laminated plates with a through hole in the vicinity of the armature face of an iron core or small grooves running from the outside face of the iron core to the armature face. CONSTITUTION:A laminated electromagnet iron core is composed of a moving iron core 3 and a fixed iron core 7. A through hole 14 is provided in the vicinity of the armature face 3a of the moving iron core 3. Small grooves 15 are formed from the through hole 14 toward the armature face 3a. An arbitrary shape such as a triangle, rectangle or a square is selected for the through hole 14. The small grooves 15 are made in an arbitrary shape such as V shape, semicircle or a plurality of small grooves. When the moving iron core 3 is dissociated from the fixed iorn core 7, air is naturally fed to the armature face 3a from the through hole 14 through the small grooves 15 to reduce the adhesion of the armature face 3a. It is thus possible to obtain a small-sized laminated iron core having a simplified construction.
