Abstract

A method of manufacturing a sport ball includes providing a fluid impervious bladder, providing apparatus for penetrating the bladder and including apparatus for receiving an object in sealing engagement, providing a plug dimensioned and configured to engage in sealing relationship the apparatus for receiving in sealing engagement, inserting the plug into the apparatus for receiving, inflating the bladder, and forming additional layers of material on the bladder that is part of a complete sport ball. Thereafter, the method includes providing a self-contained inflation mechanism dimensioned and configured to be disposed within the envelope of the sport ball and dimensioned and configured to engage the apparatus for receiving, removing the plug from the apparatus for receiving, and placing the inflation mechanism into the apparatus for receiving.

In some forms of the invention the step of forming additional layers includes adding reinforcing windings, molding a layer of rubber on the windings, and laminating composite panels onto the ball and setting the panels in a molding process.

Claims

1. A method of manufacturing a sport ball which comprises:

providing a fluid impervious bladder;

providing means for penetrating the bladder that includes means for receiving an object in sealing engagement;

providing a plug dimensioned and configured to engage in sealing relationship said means for receiving;

inserting the plug into the means for receiving;

inflating the bladder;

forming additional layers of material on the bladder that constitutes part of a complete sport ball;

providing a self-contained inflation mechanism dimensioned and configured to be disposed completely within the sport ball and dimensioned and configured to engage the means for receiving;

removing the plug from the means for receiving; and

placing the inflation mechanism into the means for receiving.

2. The method as described in claim 1, wherein said step of forming additional layers includes adding reinforcing windings.

3. The method as described in claim 2, wherein said step of forming additional layers includes molding a layer of rubber on the windings.

4. The method as described in claim 3, wherein said step of forming additional layers further includes laminating composite panels onto the ball and setting the panels in a molding process.

5. A method of manufacturing a sport ball which comprises:

providing a flat piece of rubber;

die-cutting two openings in a flat piece of rubber;

forming said flat piece of rubber into a bladder having the geometric shape of a sport ball with openings disposed in generally opposed relationship;

cementing a needle valve in one of the openings;

cementing a boot in the other of the openings in the rubber;

inserting a plug in the boot that is dimensioned and configured for sealing engagement with the boot;

forming additional layers of material on the bladder; and

replacing the plug with a self-contained inflation mechanism dimensioned and configured to be disposed completely within the sport ball and dimensioned and configured to engage the boot.

6. The method as described in claim 5, wherein said step of forming additional layers includes adding reinforcing windings.

7. The method as described in claim 6, wherein said step of forming additional layers includes molding a layer of rubber on the windings.

8. The method as described in claim 7, wherein said step of forming additional layers further includes laminating composite panels onto the ball and setting the panels in a molding process.

9. The method as described in claim 5, wherein the plug extends radially inward beyond the bladder.

10. The method as described in claim 9, wherein the plug does not extend radially outward through all of the layers of the sport ball.
