Abstract
An improved method for fabricating a filter for use in automotive air bag inflators which comprises forming a hollow cylindrical inner core or combustion screen of filter material and outer filter layers wound outward from the surface of the core so as to be maintained in cylindrical relation thereabout. This invention is specifically directed to an improved filter which does not include a perforated support tube and relies on only the interior combustion screen for support in the final wrapping of the remaining filter structure.
