Benefits of technology

[0006] With the present invention, in adhering a ball surface skin, an adhesive layer is provided on either the surface skin or the carcass, and the carcass and surface skin are adhered together. The carcass is such that either an adhesive layer is provided over

Problems solved by technology

But the use of a solvent for this purpose accompanies several problems.
There is a solvent odor and the danger of fire, which creates an unhealthful working environment; and the solvents take time to dry, take up space while drying, and require adjustment of the viscosity, which requires considerable skill.

Embodiment Construction

[0011] An embodiment of the present invention will now be described with reference to FIG. 1, which illustrates a method for adhering a surface skin of a ball. 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 then adhesion of the surface skin to the carcass is performed by a means that is free of solvent.

[0012] As shown in FIG. 2, the carcass 1 comprises the adhesive layer 2 provided over a tube 1a; or, as shown in FIG. 3, it comprises a reinforcing layer 4 provided over the tube 1a, and the adhesive layer 2 provided over the reinforcing layer 4.

[0013] Further, the adhesive layer 2 used in the present invention is selected from an adhesive film, a thermal adhesion film, a powdered adhesive agent, and a non-solvent adhesive agent.

[0014] The surface skin 3 is ...

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 1a or includes a reinforcing layer 4 provided over the tube 1a, and the adhesive layer 2 provided over the reinforcing layer 4.

Description

TECHNICAL FIELD [0001] The present invention relates to a method for adhering a surface skin of a ball. BACKGROUND ART [0002] Conventional balls used for sports include a bonded ball in which a surface skin is provided on a reinforcing layer, a rubber ball in which a rubber layer is provided on a reinforcing layer, and a stitched ball in which a surface skin and a valve portion are fixed together. [0003] On the insides of these balls is what is known as a carcass, comprising a rubber member called a tube, which has a valve and holds the air inside to become spherical when filled with air, and a reinforcing layer, which covers the tube. [0004] A surface skin is bonded over this carcass by way of using a solvent. But the use of a solvent for this purpose accompanies several problems. There is a solvent odor and the danger of fire, which creates an unhealthful working environment; and the solvents take time to dry, take up space while drying, and require adjustment of the viscosity, wh...
