1. A method for making a one-piece woven airbag, the method comprising:
(a) creating a one-piece woven fabric, the created fabric comprising a single fabric layer seam and a multiple fabric layer inflation chamber, the single fabric layer seam comprising odd-numbered woven baskets and even-numbered woven baskets; (b) feeding the created fabric into a coating machine; (c) preheating an initial outer surface of the fed fabric in the coating machine; (d) extruding a polymeric material using the coating machine; (e) coating the extruded polymeric material upon the preheated initial outer surface using the coating machine, the coated polymeric material being configured to operably reduce air permeability through the fabric if the inflation chamber is inflated, the preheated initial outer surface remaining hot during the coating, an entirety of a thickness of the coated polymeric material after solidification on the initial outer surface of the fabric being within the range of 1-6 thousandths of an inch and having a coverage area within the range of about 30-90 grams per square meter; (f) compressing the fabric in the coating machine such that the coated polymeric material on the initial outer surface is substantially solidified; (g) inverting the fabric coated on the initial outer surface such that an outer surface of the fabric that is opposite the coated initial outer surface is upwardly facing; (h) feeding the inverted fabric into the coating machine; (i) preheating the opposite outer surface of the fed inverted fabric in the coating machine; and (j) coating the extruded polymeric material upon the preheated opposite outer surface of the inverted fabric using the coating machine, wherein the coating of the extruded polymeric material upon the preheated initial outer surface and upon the preheated opposite outer surface comprises varying an amount of the extruded polymeric material such that a surface of the coated polymeric material is flat and independent of thickness variations of the created fabric. |
