  • Patent number: 6651406
    Abstract: An apparatus for forming inflated containers includes a film web that includes two juxtaposed film plies, a closed longitudinal edge, an open longitudinal edge, and a series of transverse seals having a first end located at the closed longitudinal edge and a second end terminating a predetermined distance from the open longitudinal edge such that each of the juxtaposed film plies have a section extending beyond the second end of the transverse seals, thereby forming a skirt that extends between adjacent containers at the open longitudinal edge. Such skirt facilitates inflation of each container.

  • Publication number: 20030205026
    Abstract: 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.

  • Patent number: 6276532
    Abstract: An inflatable cushion includes top and bottom sheets. The top sheet is sealed to the bottom sheet in peripheral zones to define an inflatable chamber and an inflation inlet in fluid communication with the inflatable chamber. A resistance wire extends between the top and bottom sheets and at least across the internal width of the inflation inlet. The inflation inlet further defines an inflation aperture. The inflatable cushion may be inflated through the inflation aperture and sealed by applying an electrical current across the resistance wire.

  • Patent number: 6234777
    Abstract: A foam bag cushion forming system for forming foam bag cushions with a vertical side edge sealer that forms vertical side edge seals in the film material with the foam introduction preferably occurring after the downstream side seal is formed, before the upstream side edge seal is formed, and while the film material is being shifted from one to the other. An upper edge sealer operates to seal the upper end of the film material downstream from the dispenser and preferably also downstream from the side edge sealer. Through operation of the end and side edge sealers and the foam dispenser, a foam bag cushion chain is formed. A bag cushion moving and confinement assembly is positioned to receive the bag chain and features two elongated members defining a bag cushion confinement space between them. At least one of the elongated members supports or represents a bag cushion movement device (e.g.
