Abstract: This invention relates to a method of manufacturing an ignition file for a lighter by a press and a device therefor, more particularly to an improvement of a punching operation of an axial hole for mounting an ignition file. A material pressed into a disk-like configuration is prepared and a concave portion is provided in the approximate center of both sides of the file member. A hole is punched between concave portion having a diameter smaller than that of the concave portion. The fin of the file member caused by punching is absorbed in a gap provided inside the die wall while the fin projecting toward the die hole to be punched is absorbed in said concave portion.

Abstract: Elongate wire stock of gauge appropriate to the desired diameter of a rotatable ignition file or flint wheel is cut into blanks of suitable size. A series of press operations is applied to the blanks by means of respective punches and dies to champfer or round off the peripheral edges of the blanks, to provide axial mounting holes, and to harden the respective surfaces of the blanks. The circumferential surfaces of the respective blanks are formed as friction surfaces.
