Inflatable sport ball structure and manufacturing method thereof
An inflatable sports ball structure and a manufacturing method thereof are disclosed. The inflatable sports ball structure comprises of an inner bladder, a reinforced carcass containing thread, and an exterior material layer. The reinforced carcass covers the surface of the inner bladder, and has a thread wound layer. Part of the thread wound layer is embedded in the reinforced carcass and provides a constricting force towards the inner bladder, and a small remaining part of the thread wound layer may be exposed on the outer surface of the reinforced carcass.
1. An inflatable sports ball, comprising:
a bladder having an outer surface;
a carcass covering the outer surface of the bladder and having an outer surface facing away from the outer surface of the bladder;
an exterior material layer covering the outer surface of the carcass; and
a thread wound structure, wherein a majority of the thread wound structure is in the carcass, and a minority of the thread wound structure protrudes from the outer surface of the carcass and directly contacts the exterior material layer.
2. The inflatable sports ball of claim 1 , wherein the bladder has a spherical shape.
3. The inflatable sports ball of claim 1 , wherein the carcass is made of a synthetic rubber material.
4. The inflatable sports ball of claim 1 , wherein the bladder is made of natural rubber, latex, synthetic rubber, or any combination thereof.
5. The inflatable sports ball of claim 1 , wherein the bladder is made of natural rubber, latex, butyl rubber, neoprene rubber, styrene-butadiene rubber, or any combination thereof.
6. The inflatable sports ball of claim 1 , further comprising:
an adhesive layer between the outer surface of the carcass and the exterior material layer.
7. The inflatable sports ball of claim 1 , wherein the exterior material layer is stitched onto the outer surface of the carcass.
