ABSTRACT:
A method of automatically folding an air bag having an end coupled to a retainer and an opposed distal end including flattening and narrowing the bag, providing first and second upright blade assemblies each having individually movable blades between a normal position and an interdigitated position. The bag is positioned between the blade assemblies with the retainer held and the distal end allowed to gradually move toward the retainer. Undulating folds are formed in the bag between the retainer and the distal end by moving a blade of the first assembly into a raised position, moving a blade of the second assembly into a lowered position, and alternately and individually moving each remaining blade into a raised and lowered positions, respectively, while allowing the distal end of the bag to gradually move toward the retainer as each undulating fold is formed.
