Abstract

A method of manufacturing a lower blade for a dry razor, of the type comprising a thin, arched, perforated elastic plate serving as the upper blade, on the surface of which a multiplicity of openings for hair entry are distributed, and under which a lower blade is arranged which can be reciprocated, the lower blade comprising an elastic and arched shear plate, substantially rectangular in flat condition which, by its longitudinal edges, is secured to a frame and which is provided of elongated openings, arranged substantially transversely to the longitudinal sides, said openings being joined on the convex side of the shear plate arched by ribs whose sharp edges constitute the edges of the lower blade, which method is characterized in that it includes following operations: 1) manufacture a mold producing photographic in a manner known per se, on a non-metallic base, an exterior metallic design in the form of a ladder, comprising two parallel side strips which are interconnected by several parallel ribs, identical to each other, which are connected smoothly to the side strips cited; 2) depositing a metallic layer on the metallic design by electroforming, so that a shear plate is obtained by deposition; 3) removing the deposited shear plate from the mold, and 4) mounting the shear plate on a frame in an arched condition such that the convex side of the shear plate is the surface that originally faced the mold.
