Abstract: A method of manufacturing a fluid-filled chamber may include utilizing one of a blowmolding and a thermoforming process to define a first surface, a second surface, and a sidewall surface of the chamber. An aperture is defined through the first surface in a location where the first surface is spaced from the second surface. A pressurization apparatus is located adjacent to the first surface and around the aperture, and the pressurization apparatus is utilized to inject a fluid into the chamber through the aperture, compress the first surface against the second surface, and form a bond around the aperture and between the first surface and the second surface.

Abstract: A mold may include mold portions that each includes a surface, a cavity formed in the surface, and a movable frame that extends around the cavity. In manufacturing a fluid-filled chamber, a parison may be located between the mold portions. The mold portions are moved toward the parison such that the frames contact and compress opposite sides of the parison to form a first bond between the opposite sides of the parison. The parison is also compressed between the mold portions such that opposite sides of the parison are shaped within the cavities to define the chamber and form a second bond immediately adjacent to the chamber.

Abstract: A fluid-filled chamber for an article of footwear and a method for manufacturing the chamber are disclosed. The chamber may be incorporated into a sole structure of the footwear and includes a central area and a plurality of lobes extending outward from the central area. The lobes are in fluid communication with the central area and are formed from a first surface, a second surface, and a sidewall. The sidewall joins with the first surface with the second surface to seal the fluid within the chamber, but no internal connections are generally utilized to join interior portions of the first surface with interior portions of the second surface. The fluid within the chamber may be air at a pressure that is approximately equal to an ambient pressure.
