发明名称 Apparatus and method for manufacturing double layer air cylinder type air enclosure
摘要 An apparatus and method for manufacturing a double layer air cylinder type air enclosure uses a middle film conveying unit to provide a middle film, a plurality of inner film conveying units to provide a plurality of inner films to stack on two sides of the middle film, a first hot sealing apparatus to hot-seal the plurality of inner films and the middle film to allow two sides of the middle film to be respectively formed with a check valve with an air passageway, an outer film conveying unit to provide two sheets of outer film to respectively stack on the outside of the check valve and a second hot sealing apparatus to hot-seal the plurality of outer films and the middle film to allow an air storable air chamber to be formed between the middle film and the each sheet of outer film. Whereby, air enters the air chamber causes the air chamber to be filled with air and expanded via the air passageway, air in the air chamber compresses the check valve to shield the air passageway to enable air in the air chamber not to be leaked out to attain to the air locking.
