Abstract:
1. A method of manufacturing a fluid-filled chamber, the method comprising: locating a tensile member between a first polymer sheet and a second polymer sheet, the tensile member having a first layer, an opposite second layer, and a plurality of connecting members; pressing the first polymer sheet against the first layer and the second polymer sheet against the second layer to form (a) a plurality of indentations and a plurality of protrusions in the first polymer sheet and (b) a plurality of indentations and a plurality of protrusions in the second polymer sheet, the protrusions in the second polymer sheet being formed opposite the indentations in the first polymer sheet; joining the first polymer sheet and the second polymer sheet to form a peripheral bond and thereby form a chamber; and pressurizing the chamber to place the connecting members in tension.
