Abstract:
1. A method of manufacturing a sportsball, comprising the steps of: (a) forming a ball pocket, which is constructed to have a true roundness, having an interior cavity, wherein the step (a) further comprises the steps of: (a.1) providing a parent bladder having a true roundness shape after said parent bladder is inflated; (a.2) overlapping a plurality of pocket panels on said parent bladder at a position that edge portions of said pocket panels are overlapped with edge portions of adjacent pocket panels, wherein one of said pocket panels, having a valve hole, is remained unattached to form an inlet opening; (a.3) heat-treating said pocket panels to integrally bond said ball panels together to form a hollow round ball body having said inlet opening provided thereon; (a.4) removing said parent bladder from said hollow round ball body through said inlet opening after said parent bladder is deflated; (a.5) disposing an inflatable bladder in said hollow round ball body through said inlet opening before said inflatable bladder is inflated; and (a.6) sealing said inlet opening with attaching said unattached pocket panel at a position that said valve hole is aligned with said valve stem to sealedly enclose said interior cavity to form said ball pocket; (b) the inflatable bladder, having a valve stem, wherein when said inflatable bladder is inflated, said ball pocket retains a true roundness shape of said inflatable bladder; (c) forming a ball cushion, which is constructed to have a true roundness, to receive said ball pocket therein; and (d) affixing a plurality of carcass panels on said ball cushion to form a roundness carcass of said sportsball in a stitch-less manner, wherein each of said carcass panels having a peripheral edge and a flat bottom surface defined within said peripheral edge, wherein said bottom surface of each of said carcass panels is entirely affixed to said ball cushion at a position that said peripheral edge of each of said carcass panels is fittingly aligned with said peripheral edges of said adjacent carcass panels to form said roundness carcass of said sportsball.
