Abstract
An improved method for the fabrication of filter assemblies for use in automotive air bag inflators by spirally winding a hollow cylindrical combustion screen comprised of layers of filter material. The spirally wound filter is then cut into individual units of desired length by the use of a conventional cutting device and additional filtering layers can optionally be added to form an inflator filter assembly.
