A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

Apparatus and method for making inflated articles

An apparatus for forming flexible containers from a film web, dispensing fluid into the containers, and enclosing the fluid within the containers. The film web comprises a pair of juxtaposed film plies, a closed longitudinal edge at which the plies are joined, and an open longitudinal edge at which the plies are not joined.

Apparatus for forming flexible containers, dispensing fluid into the containers, and enclosing the fluid within the containers

An apparatus for making inflated containers from a film web having two juxtaposed film plies generally includes (a) a first sealing device for producing a series of transverse seals that bond the film plies together, (b) an inflation assembly for directing gas between the film plies, (c) a second sealing device for producing one or more longitudinal seals that bond the film plies together, the transverse seals and the longitudinal seals intersecting to enclose the gas between the film plies to thereby form one or more inflated containers, and (d) at least one intermediate sealing element for producing one or more intermediate seals within each inflated container, the intermediate seals partitioning the containers into two or more compartments and providing at least one flow passageway between the compartments to allow the compartments to fluidly communicate with one another.

An inflator/sealer machine useful for inflating and sealing an inflatable cushion having a resistance wire that extends across the inlet of the inflatable cushion. The machine includes an inflation tube, a seal bar, and an anvil. The inflation tube is connected to a source of inflation fluid and has an outlet that is larger than the inflation aperture of the inflatable cushion. The inflation tube and anvil are adjustable between a tube/anvil engaged position and a tube/anvil disengaged position. In the tube/anvil engaged position, the inflation tube outlet opposes the anvil and can engage the inflation aperture of the inflatable cushion between the inflation tube and the anvil to inflate the cushion. The seal bar and the anvil are adjustable between a bar/anvil engaged position and a bar/anvil disengaged position. In the bar/anvil engaged position, the anvil opposes the seal bar to compress the inlet heat seal zone of the inflatable cushion between the anvil and the seal bar. Left and right contacts are positioned on opposing sides of the seal bar during the bar/anvil engaged position. The contacts are connected to an electrical power source. The contacts touch the resistance wire that extends across the inlet of the inflatable cushion to complete an electrical circuit during the bar/anvil engaged position and form a heat seal across the inlet of the inflatable cushion.

Inflator/sealer device for inflatable packaging cushion

There is provided an inflatable cushion filling machine for forming inflated packaging cushions from a roll of tubular thermoplastic material. The machine includes a film supply section and a cushion forming section. The cushion forming section includes means for delivering the tubular material through the cushion forming section; means for applying tension to the web of tubular material while air is being introduced into the tubular material. Means are provided for introducing air into the area between the tension means to fill the cushion. When filled, a sealing band, displaced transversely across the inflated tubular thermoplastic material, seals the lower end to form the top of one cushion and the bottom of the next cushion. Prior to forming the cushion, the walls of the tubular material separate from each other by the residual air from the filling operation of the previous cushion. A perforation knife may be provided to separate each cushion from the next succeeding cushion.

Inflatable cushion forming machine

An apparatus is disclosed for automatically molding defined three-dimensional foam cushions. The apparatus comprises means for preparing a bag from plastic film material and for enclosing a foamable composition in the plastic bag, means for concurrently aligning a mold with the plastic bag and the bag preparing means, means for placing the bag containing the foamable composition into the aligned mold as the foamable composition begins to form foam, and means for maintaining the bag in the mold until the foamable composition has substantially finished forming foam in a shape conforming to the mold.
