Abstract: A sports ball having a high-performance cover formed from a plurality of panels with attached foam backing. The panels may be stitched together at stitch lines which are 2-4 mm from the edges of each of the panels. During manufacturing, before compression is applied, foam attached to outer layers for each of the panels may be a distance 2-6 mm away from the stitch lines. Foam attached on the inside of the sports ball may provide support and a robust round shape for manufacturing of a high performance sports ball.

Abstract: A non-pressurized sport ball that simulates the resiliency, rebound, hardness and weight properties of a similar sized, inflatable sports ball. The sports ball, which can be made in different sizes and shapes, includes a hollow ball body with relatively thick sidewalls made of closed-cell foam, elastomeric resin. When cured, the sidewalls have compression and resiliency properties that enable the working action of the sidewalls to be used in place of an air bladder in an inflatable sports ball. Formed on the ball body is an entry hole in which an air escaping cap is inserted made of the same elastomeric resin material as the ball body. During use, the cap flexes within the entry hole to allow air to exit and enter the ball during use so that the internal and external air pressures are equal. Also disclosed is a method of manufacturing the sports ball using a mandrel and a suitable-shaped compression mold with an entry hole formed on one side.

Abstract: A foam game ball is provided which is adapted to absorb water and includes holes along the length of the ball so as to allow centrifugal force to cause the water to be expelled through the holes when the ball is saturated with water and thrown or kicked. The ball further includes a core, such as a hollow bladder with a non-absorbent outer surface, with an average specific weight less than the specific weight of the foam when fully saturated with water.
