Abstract
A sports ball and a method of manufacturing the same are provided. The sports ball having a bladder, an outer cover layer, and an intermediate structure disposed between the outer cover layer and the bladder. The intermediate structure includes a restriction structure comprising a plurality of overlapping layers of cross-linked polymer film wrapped about the bladder. The sports ball may be formed via the steps of surrounding the bladder, having a first initial circumferential dimension, with a plurality of overlapping layers of cross-linked polymer shrink film, such that the cross-linked shrink film forms a restriction structure in a first dimensional state; applying a heat shrinking process to the cross-linked polymer shrink film to contract the restriction structure from the first dimensional state to a second dimensional state; inflating the bladder to a second circumferential dimension; and disposing the outer cover layer and intermediate layers about the bladder and restriction structure.
