Abstract
A method of forming a fluid-filled chamber for an article of footwear is provided and includes positioning a first sheet of material and a second sheet of material in a pressure chamber, increasing a fluid pressure within the pressure chamber to a first value, and coupling the first sheet of material to the second sheet of material within the pressure chamber to define a fluid-filled chamber defined by the first sheet of material and the second sheet of material and having a fluid pressure equal to the first value. The method also includes decreasing the fluid pressure within the pressure chamber to a second value.

A method of forming a fluid-filled chamber for an article of footwear, the method comprising:
- positioning a first sheet of material and a second sheet of material in a pressure chamber;
- increasing a fluid pressure within the pressure chamber to a first value;
- applying pressure at the first value to both sides of a least one of the first sheet of material and the second sheet of material within the pressure chamber;
- coupling the first sheet of material to the second sheet of material within the pressure chamber to define a fluid-filled chamber defined by the first sheet of material and the second sheet of material and having a fluid pressure equal to the first value;
- and
- decreasing the fluid pressure within the pressure chamber to a second value.
A method of forming a fluid-filled chamber for an article of footwear, the method comprising:
- positioning a first sheet of material in a pressure chamber;
- pressurizing the pressure chamber to a fluid pressure equal to a first value;
- applying pressure at the first value to both sides of the first sheet of material within the pressure chamber;
- forming a fluid-filled chamber from the first sheet of material, the fluid-filled chamber having a fluid pressure equal to the first value;
- and
- depressurizing the pressure chamber to reduce the fluid pressure within the pressure chamber to a second value.
