<p>This invention relates to an apparatus for automatically charging a gas into a gas bag having continuous independent gas chambers which is used as a buffer material for packaging, and the like. The gas charging apparatus for the gas bag (12) having the continuous independent gas chambers comprises a core (23) which is inserted into a passage (19) of the gas bag (12) and has a small diameter portion (26) at an intermediate part thereof in a longitudinal direction, pinch rollers (21) which clamp the gas bag (12) at the position of the small diameter portion (26) of the core (23) and send the gas bag (12) in its longitudinal direction, a nozzle adaptor (29) which is removably inserted into an opening of the passage (19) which is opened by the insertion of the core (23), a moving device (23) which moves the nozzle adaptor (29) lest the adaptor (29) falls off from the opening during the movement of the gas bag (12) in the longitudinal direction, gas feeding devices (31, 32) connected to the nozzle adaptor (29), a nip device (33) for nipping the gas bag (12) so as to close the passage (19) at the rear end position of the gas bag (12) which has moved by a predetermined distance in the longitudinal direction, and a cutting device (34) for cutting the rear end portion of the gas bag (12) across its full width. <IMAGE></p> |
