Method for adhesion of surface skin of ball

Abstract

A method for adhering a surface skin of a ball, which uses a means that is free of solvent and involves no solvent, and which is friendly to the environment, creates no odor, poses no danger of fire attributable to catalysts, eliminates the solvent drying time and space that would otherwise be required, and requires no particular skill. In a ball, an adhesive layer 2 is provided on the outer surface of a carcass 1 , and a surface skin 3 is placed over the adhesive layer 2 ; or the adhesive layer 2 is provided on the inner surface of the surface skin 3 , and the surface skin 3 is placed over the carcass 1 ; and adhesion is performed using a means free of solvent. Here, the carcass 1 includes the adhesive layer 2 provided over a tube 1 a or includes a reinforcing layer 4 provided over the tube 1 a , and the adhesive layer 2 provided over the reinforcing layer 4.

1 . A method for adhering a surface skin of a ball, comprising the steps of providing an adhesive layer on an outer surface of a carcass and placing a surface skin over said adhesive layer, or providing an adhesive layer on an inner surface of a surface skin and placing said surface skin over a carcass; and then performing adhesion with a means that is free of solvent.  
   
   
       2 . The method for adhering a surface skin of a ball according to  claim 1 , wherein the carcass is produced by either providing an adhesive layer over a tube or providing a reinforcing layer over a tube and providing an adhesive layer over said reinforcing layer.  
   
   
       3 . The method for adhering a surface skin of a ball according to  claim 1 , wherein the adhesive layer is one selected from an adhesive film, a thermal adhesion film, a powdered adhesive agent, and a non-solvent adhesive agent.  
   
   
       4 . The method for adhering a surface skin of a ball according to  claim 1 , wherein the means free of solvent is heating, pressing, or rubbing.
