    摘要: An apparatus and method of manufacturing a plurality of air bags for use in a motor vehicle, and air bags made by same. First and second fabric layers of a type of fabric suitable for use in a vehicle air bag are fed into a seaming station. At the seaming station, the fabric layers are seamed together according to a predetermined seaming pattern so as to produce a composite textile structure defining a plurality of individual air bags to be cut therefrom. Depending on the application, the seaming may be accomplished by stitching or welding. If the fabric layers are not precoated, a suitable coating material may then be applied to both outer surfaces of the composite textile structure so as to render the air bags substantially impermeable to passage of air. Finally, the plurality of individual air bags are cut from the composite textile structure.
