Method Of Manufacturing A Fluid-Filled Chamber With A Tensile Element

摘要

A method of manufacturing a fluid-filled chamber with a tensile element includes manufacturing a tensile element and incorporating the tensile element into a chamber. A first material layer, a second material layer, and a spacing structure having a plurality of support portions and a plurality of gaps may be stacked. The material layers may be located on either side of the spacing structure or on one side of the spacing structure. A strand may be stitched through the gaps to join the material layers and to form the tensile element. The spacing structure may be removed, and the first material layer may be spaced from the second material layer such that segments of the strand extend between the material layers. The tensile element may then be secured to opposite interior surfaces of an outer barrier, and the outer barrier may be pressurized to place the strand in tension.

1. A method of manufacturing a fluid-filled chamber, the method comprising steps of:
stacking a first material layer, a second material layer, and a spacing structure having a plurality of support portions; stitching between the support portions with a strand to join the first material layer to the second material layer and to form a tensile element from the first material layer, the second material layer, and the strand; positioning the tensile element within an outer barrier; securing the first material layer and the second material layer to opposite interior surfaces of the outer barrier; and pressurizing the outer barrier to place the strand in tension.
