METHOD OF MANUFACTURING A FLUID-FILLED CHAMBER WITH A REINFORCING ELEMENT

Abstract:

Several sole components and a method of manufacturing those sole components are disclosed. In general, each sole component includes a fluid-filled bladder and a reinforcing element extending around a portion of the bladder. The reinforcing element is bonded to the exterior of the bladder, and may be recessed into the bladder. In some configurations, the reinforcing element is die-cut from a sheet of polymer material, and the reinforcing element may exhibit a layered configuration. In manufacturing the sole component, the reinforcing element may be located within a mold, and the polymer material forming the bladder may be bonded to the reinforcing element during the molding process.
