  • GAS GENERATING AGENT, PROCESS FOR PRODUCTION THEREOF, AND GAS GENERATORS FOR AIR BAGS
    Publication number: 20090102080
    Abstract: There is provided a tubular molded article of a gas generating agent consisting of a non-azide-based composition. Both ends of the molded article are squashed. A gas-generating-agent producing process is to obtain a gas generating agent which is molded into the form of a tube both ends of which are squashed in such a way that the tubular molded article of the gas generating agent being in a wetted state is passed through a gap between a pair of molding gears that are rotatable so that each convex tooth of one of the molding gears can face that of the other molding gear, thereafter the molded article is squashed with the convex teeth at predetermined intervals, thereafter the molded article is cut off at the squashed concave parts in such a way as to be folded, and the resultant cut pieces are dried.
