A gas bag folding system is disclosed for a gas bag used in an air bag module, as well as a process and device for holding a gas bag in this manner. A top and a bottom layer (2, 3) of the gas bag have each at least one main fold (2a-2d, 3a-3d, 2e-2h, 3e-3h, 15), the main folds extending separately from each other. To fold the bag in this manner, the empty gas bag is outspread so that is has a top layer and a bottom layer, the two layers are separately folded and the folds are gathered together to the required size for packaging in an air bag module. A device for folding the bag in this manner is characterised in that separate folding devices which extend at least approximately perpendicular to the top and bottom layers (2, 3) of an outspread gas bag (1) are associated to the top and bottom layers (2, 3) of the gas bag and can be moved in the direction of the outspread gas bag, and in that an overpressure generator can be connected to the gas bag.
