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 oper...

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 chanc...

first embodiment

[0037]Referring to FIGS. 1 to 4 of the drawings, a sportsball and its manufacturing method according to the present invention are illustrates, wherein the sportsball, such as a soccer ball, is a stitching type sportsball and comprises an inflatable ball body 10, and a ball carcass 20 having a ball cavity 21 and an opening 22.

[0038]The ball body 10 is disposed in the ball cavity 21 through the opening 22 for propping up the ball carcass 20 after inflation. As shown in FIGS. 1 and 3, the ball body 10 comprises an inflatable bladder 11 for being popped by air inflation via a valve stem and an exterior web layer 12, which is integrally attached on an outer surface of the lo inflatable bladder 11, comprises at least an elongated winding thread 121 evenly wound around the outer surface of the inflatable bladder 11 such that the web layer 12 embraces the inflatable bladder 11 for resisting stress and impact force applied to the inflatable bladder 11. Accordingly, the purpose of the thread ...

second embodiment

[0074] the adhesive layer 31′ is provided at a closing area 101′ of the ball body 10′, wherein the closing area 101′ is an area on the outer surface of the ball body 10′ that when the ball body 10′ is disposed in the ball carcass 20′, the closing area 101′ is facing towards the opening 22′ of the ball carcass 20′. In particularly, the adhesive layer 31′ is a rubber strip pre-applied on the outer surface of the ball body 10′ to form a hexagonal contour matching with the hexagonal contour of the opening 22′. After the ball body 10′ is disposed in the ball carcass 20′, the adhesive layer 31′ is aligned with the opening 22′ of the ball carcass 20′. Therefore, the edge portions of the opening 22′ are adhered on the outer surface of the ball body 10′ through the rubber strip after heat treatment.

[0075]It is appreciated that the adhesive layer 31′ is extended throughout the entire ball body 10′, as shown in FIG. 5, wherein the adhesive layer 31′ is provided on the ball body 10′ along the e...

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...
