Abstract

Procedure for the manufacture of razor blades for dry shaving appliances, in which a rubber traction cutting procedure is applied for the stamping of the extraction of the holes and in the same working phase, for the beading of the edges of the holes in the strips, which form a coherent network between the holes, by means of a matrix, whose convex parts for the stamping of the holes have a greater diameter than at their free end and in which the edges of the holes are subsequently rectified in a plane, parallel to the surface of the sheet with only partial detachment of the material, which protrudes above the surface of the sheet, characterized in that when compressing the rubber pad and the matrix in a first stage of the single work phase, starting of the metallic sheet located between the matrix and the rubber pad, first only the holes are stamped and immediately afterwards, and in a second stage of this fas e single work, the edges of the holes are flanged, for which a matrix is used, the convex parts of which are in each case made up of two sectors, between which a beveling of a staggered shape is provided, in which the height of the sector at the free end of each convex part is at least equal to the thickness of the sheet.
