Patent ID: 8375681

Claim:
An air injection apparatus for a buffer packing bag, the apparatus comprising: a nozzle adapted to be inserted into an entrance opening of an air injection passage of the buffer packing bag positioned at a front side of the air injection apparatus so as to inject air into the entrance opening of the air injection passage, wherein the nozzle is connected to a first actuator so that the nozzle is moved forwardly and backwardly by means of the operation of the first actuator; a clamp adapted to pressurize the entrance opening of the air injection passage in a state where the nozzle has been inserted into the entrance opening of the air injection passage so as to prevent the air from leaking to the outside via the entrance opening; a second actuator adapted to driven to cause the clamp to pressurize the entrance opening of the air injection passage; a heater adapted to pressurize and heat-bond the entrance opening of the air injection passage; and a third actuator adapted to move the heater to the entrance opening of the air injection passage.
