Abstract
A method of manufacturing at low pressure armed headgear helmets, molded plastic material consisting essentially of disposing at the bottom of a mold that presents in negative the external shape of the helmet a piece of steel fabric that extends throughout the corresponding part to the vault of the head covering, to insert in the mold a counter-mold that corresponds to it and is of sufficiently small volume so that it can be between one and the other a space equal to the thickness that has been foreseen that the helmet must be molded by filling said space with the plastic material fused with fiberglass in dispersion in it.
