Patent ID: 7128796

Claim:
A method of blow-molding a fluid-filled chamber for an article of footwear, the method comprising steps of: positioning a parison between a first portion and a corresponding second portion of a mold; pressurizing an interior of the parison; bending the parison with contours of the mold as the first portion and the second portion translate toward each other, the contours of the mold having surfaces that are positioned separate from surfaces of a cavity within the mold, the cavity having a shape of the chamber; shaping opposite sides of the parison to form the chamber within the cavity; bonding the opposite sides of the parison together to define a parting line with a portion that extends from a first side to an opposite second side of the chamber, and the parting line extending around a majority of the chamber to separate the chamber from excess portions of the parison; and removing the excess portions of the parison.
