Ball

Abstract

A ball has a core and a cover surrounding the core. The cover is made of a rubber material and surrounding the core. The cover has two half pieces sewn together with each other, and each half piece has a fabric lining securely attached to an inner surface of the half piece with a ripening process. Accordingly, the cover made of a rubber material has an excellent wear-resisting efficiency and will not contain water, such that the useful life of the ball is prolonged.

What is claimed is:  
     
         1 . A ball comprising: 
 a core; and    a cover made of a rubber material and surrounding the core, the cover having two half pieces sewn together with each other,    wherein each half piece has a fabric lining securely attached to an inner surface of the half piece with a compressing and vulcanizing process.    
     
     
         2 . The ball as claimed in  claim 1 , wherein the fabric lining is made of a strong fabric material.  
     
     
         3 . The ball as claimed in  claim 2 , wherein the fabric lining is a blend fabric of artificial fiber and cotton.  
     
     
         4 . The ball as claimed in  claim 1 , wherein each half piece has multiple through holes defined around a periphery of the half piece for a combining wire extending through the through holes in the half pieces in turn so as to sew the half pieces into a cover.
