Stitchless seam arrangement of sportsball and manufacturing method thereof

Abstract

A sportsball includes a ball carcass, an inflatable ball body received in a ball cavity of the ball carcass, and a stitchless seam arrangement which includes an elongated adhesive layer having a contour matching with a contour of an opening of the ball carcass, wherein after the ball body is disposed in the ball carcass, edge portions of the opening are adhered on an outer surface of the ball body via the adhesive layer, such that the opening is sealed to close the ball cavity for enclosing the ball body in the ball cavity of the ball carcass in a stitchless seam manner. Therefore, the manufacturing method of the sportsball excludes the traditional final assembling operation of hand stitching to reduce the time-consuming manufacturing procedure of the sportsball while being cost effective.

Description

CROSS REFERENCE OF RELATED APPLICATION[0001]This is a non-provisional application of a provisional application having an application number 61 / 133,678 and a filing date of Jun. 30, 2008.BACKGROUND OF PRESENT INVENTION[0002]1. Field of Invention[0003]The present invention relates to a sportsball, and more particularly to a stitchless seam arrangement of a sportsball and a manufacturing method thereof, which can simplify the final assembling operation of the sportsball by sealing the opening of the ball carcass by means of adhesive so as to reduce the time-consuming manufacturing procedure of the sportsball while being cost effective.[0004]2. Description of Related Arts[0005]A conventional sportsball, such as a conventional soccer ball, America football, or volley ball, usually comprises a ball bladder and a ball casing. The ball casing comprises a plurality of casing panels attached on the ball bladder, wherein each of the casing panels is usually stitched to adjacent casing panels e...

AI Technical Summary

Benefits of technology

[0009]A main object of the present invention is to provide a stitchless seam arrangement of a sportsball and a manufacturing method thereof, which can simplify the final assembling operation of the sportsball by sealing the opening of the ball carcass by means of adhesive so as to reduce the time-consuming manufacturing procedure of the sportsball while being cost effective.

[0010]Another object of the present invention is to provide a stitchless seam arrangement of a sportsball and a manufacturing method thereof, which can significantly increase the productivity along with the production quality consistency.

[0011]Another object of the present invention is to provide a stitchless seam arrangement of a sportsball and a manufacturing method thereof, wherein the stitchless seam arrangement can integrally formed with the ball body so as to completely overcome the insecure attachment disadvantage for conventional sportsball.

[0012]Another object of the present invention is to provide a stitchless seam arrangement of a sportsball and a manufacturing method thereof, which does not require to alter the original structural design of each of the ball body and the ball carcass, so as to minimize the manufacturing cost of the sportsball incorporating with the stitchless seam arrangement.

[0014]Another object of the present invention is to provide a stitchless seam arrangement of a sportsball and a manufacturing method thereof, wherein the sportsball can be manufactured into a wide variety of ball types, so as to facilitate widespread applications of the present invention. For example, by using the structural configuration of the stitchless seam arrangement, the sportsball can be manufactured as a soccer ball, an America football, or even a volley ball.

[0015]Another object of the present invention is to provide a stitchless seam arrangement of a sportsball and a manufacturing method thereof, wherein no expensive or complicated structure is required to employ in the present invention in order to achieve the above mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution for manufacturing a long-lasting configuration for the sportsball.

Problems solved by technology

It is worth to mention that the final assembling operation can only be operated by hand stitching that the opening of the ball casing cannot be closed by any sewing machine.

However, the final assembling operation of the sportsball is relatively expensive and time-consuming due to the hand stitching operation.

When the sportsballs are needed in large quantity, such as when the inventors or their assignees or the licensors need to meet substantial market demand, there is little chance that they could produce the sportsballs in large quantity in a relatively short period of time.

However, another problem for such improved sportsball is that no matter how good the stitching and / or the construction of casing panels, the ball bladder and the ball casing are inherently two different components.

The ball casing may be attached onto the ball bladder with the lining in between, the attachment is complicated and is not durable, so as to reduce the life span of the sportsball.
