Abstract:
1. A method for fabricating an air-filled cellular structure for use as a resilient cushion, comprising: providing a molding structure including a shelf substantially surrounding a depression, and a platform that fits within the depression and is selectively movable between a plurality of positions relative to the shelf; moving the platform to a preselected position relative to the shelf, wherein the preselected position corresponds to a substantially predetermined volume of air to be contained by the air-filled cellular structure; using a vacuum device to draw air from within the depression; engaging a first portion of a first expanse of generally air-impermeable material with the shelf, whereby the vacuum device draws a second portion of the first expanse of material against the moveable platform; bonding a first portion of a second expanse of generally air-impermeable material to the first portion of the first expanse, thereby enclosing a volume of air between the first and second expanses.
