Systems and methods for producing a ball

摘要

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.
