ABSTRACT:
An apparatus for making inflated articles from a film web having two juxtaposed film plies. One version of the apparatus generally includes a first rotary sealing device for producing transverse seals that bond the film plies together, an inflation assembly for directing gas between the film plies, and a second rotary sealing device for producing a longitudinal seal between the film plies. The longitudinal seal intersects the transverse seals so that the gas is enclosed between the longitudinal seal, transverse seals, and film plies to thereby form an inflated article.
