This invention relates to a gas injection device for automatically supplying a flow of gas to a gas bag having serial closed cells to be used, for example, as a cushioning material for packaging operation. The gas injection device for a gas bag having serial closed cells includes a core (23) adapted to be inserted into a passage (19) of the gas bag (12), the core having a longitudinally intermediate portion (26) of a reduced diameter, at least two pinch rollers (21) for pressingly clamping said gas bag (12) at the position of the longitudinal intermediate portion (26) of a reduced diameter of the core (23), so as to drive the gas bag (12) in the longitudinal direction, a nozzle adapter (29) adapted to be withdrawably insertable into the opening of the passage (19) which is opened by the core (23) inserted therein, a displacer means for displacing the nozzle adapter (29) in a manner in which the nozzle adapter (29) is not displaced from the opening of the passage (19), when the gas bag (12) is driven in the longitudinal direction, a gas supply means (31, 32) adapted to be connected with the nozzle adapter (29), a nip means (33) for pressingly clamping the gas bag (12), so as to close the passage (19) of the gas bag (12) having been displaced a predetermined distance in the longitudinal direction at the terminal end of the core (23), and a cutter means (34) for severing the terminal end of the gas bag (12) along its entire width.
