Abstract:
1. A method of manufacturing a fluid-filled chamber, the method comprising: placing a tensile member between a first layer and a second layer of polymer material, the tensile member having a first portion with greater compressibility than a second portion; locating the tensile member, the first layer, and the second layer within a mold, the mold having a protrusion in an area that contacts the first layer adjacent to the first portion of the tensile member; and compressing the tensile member, the first layer, and the second layer within the mold to apply pressure with the protrusion to the first layer and the first portion of the tensile member and to also bond (a) the first layer to a first surface of the tensile member, (b) the second layer to a second surface of the tensile member, and (c) the first layer and the second layer together around a periphery of the tensile member.
