Air inflated sports ball

摘要

The sports ball comprises an inflatable tube, a covering layer which comprises a very thin rubber pouch and a covering around the tube. A reinforced layer is formed on the surface of the covering layers. An outer layer is formed on the surface of the reinforced layers. An inorganic lubricant is located between the tube and the covering layer from which the tube is spaced. The covering layer which covers the tube is made of a material which does not permit a solution of an adhesive agent such as an aqueous solution of latex or a solution of an adhesive agent which contains rubber to pass through the covering layer. The reinforced layer is formed by attaching cloth pieces on the surface of the covering layer and fixing with a solution of the adhesive agent.
