摘要:
A method of manufacturing a sport ball (10) includes providing a fluid impervious bladder (12), providing apparatus for penetrating the bladder and including apparatus for receiving an object in sealing engagement, providing a plug (25) 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 (14, 16) of material on the bladder that is part of a complete sport ball. Thereafter, the method includes providing a self-contained inflation mechanism (82) 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.
