A method of manufacturing a sport ball includes providing a plurality of casing panels including a first panel and a second panel. The first panel has a first surface and an opposite second surface. The first panel includes a first flange area forming a first edge portion of the first panel. The second panel has a third surface and an opposite fourth surface. The second panel includes a second flange area forming a second edge portion of the second panel. The method includes turning the first flange area away from the first surface of the first panel, turning the second flange area away from the third surface of the second panel, abutting the first flange area and the second flange area, and joining the first panel to the second panel.

Sport ball casing with thermoplastic reinforcing material

A sport ball may have a plurality of panels that are joined at seams to form a casing. The panels may include a thermoplastic polymer material applied to an interior side of the panels, and the thermoplastic polymer material may be heat-activated to extend across the seams. The ball may further include a bladder within the casing and an intermediate layer located between the casing and the bladder. The thermoplastic polymer material may also be heat-activated to bond with the intermediate layer or casing.
