ABSTRACT:
A process for making blades of an electric plug directly from a linear strip includes: forming a longitudinal metallic strip from a rod coil; punching the strip to form plural blade members; directly flattening and thinning a rear root portion of each blade for crimping an electric wire so that a longitudinal strip can be conveniently formed into a plurality of plug blades without wasting much scraps cut from the metallic strip.
