Abstract

A sport ball may include a casing that forms an exterior surface of the sport ball. The casing may incorporate a plurality of joined panels, including a closure panel. In addition, the ball may include a backing layer located radially inward of the closure panel, the backing layer extending beyond a peripheral boundary of the closure panel and at least partially overlapping with one or more panels adjacent to the closure panel. The backing layer may also include an opening located radially inward of the closure panel, the opening being smaller than the surface area of the closure panel. Also, the ball may include a bladder located radially inward of the backing layer, the bladder including a valve for introducing fluid into the ball, the valve extending through the opening and through the closure panel.

First claim

The invention claimed is:

1. A method of making a sport ball, comprising:
forming a partially assembled casing by joining a plurality of panels, leaving open one area configured to receive a closure panel, wherein the partially assembled casing is formed inside-out;
placing a backing layer over at least a portion of the inside-out, partially assembled casing,
locating an opening in the backing layer over the open area of the partially assembled casing configured to receive the closure panel, the opening in the backing layer being smaller than the open area of the partially assembled casing;
turning the partially assembled casing and backing layer right-side-out through the opening in the backing layer and the open area of the partially assembled casing; and
installing the closure panel in the open area against the backing layer.

2. The method of claim 1 , wherein said installing the closure panel includes attaching the closure panel to the backing layer with adhesive.

3. The method of claim 1 , wherein said installing the closure panel includes attaching the closure panel to panels adjacent to the closure panel by welding.

4. The method of claim 1 , further including inserting a bladder into the partially assembled casing through the opening in the backing layer.

5. The method of claim 4 , wherein the bladder is attached to the closure panel.

6. The method of claim 5 , wherein the bladder includes a valve for introducing fluid to the bladder, the valve extending through the closure panel.

7. A method of making a sport ball, comprising:
forming a partially assembled casing by joining a plurality of panels, the partially assembled casing including an open area;
securing a backing layer to an interior surface of the partially assembled casing, the backing layer including an opening located within the open area, wherein the opening in the backing layer is smaller than the open area of the partially assembled casing;
positioning a bladder within the partially assembled casing by inserting the entire bladder through the opening of the backing layer;
locating a closure panel in the open area; and
securing the closure panel to the backing layer.

8. The method of claim 7 , wherein the backing layer includes a backing patch that partially covers the interior surface of the partially assembled casing.

9. The method of claim 8 , wherein the partially assembled casing is formed inside-out, and further including turning the partially assembled casing right-side-out.

10. The method of claim 9 , wherein securing the backing patch to the interior surface of the partially assembled casing is performed after the partially assembled casing is turned right-side-out.

11. A method of making a sport ball, comprising:
forming a partially assembled casing by joining a plurality of panels to one another, the partially assembled casing including an open area;
securing a backing layer to an interior surface of the partially assembled casing, the backing layer including an opening located within the open area, wherein the opening in the backing layer is smaller than the open area of the partially assembled casing;
positioning a bladder within the partially assembled casing through the opening of the backing layer;
attaching a piece of material to the inside of a closure panel, the piece of material being formed of the same material as the backing layer;
locating the closure panel in the open area such that the piece of material is disposed within the opening in the backing layer and the piece of material attached to the inside of the closure panel is in contact with the bladder; and
securing the closure panel to the backing layer.

12. The method of claim 11 , wherein the bladder includes a valve for introducing fluid into the ball, the method further including extending a portion of the valve through the opening in the backing layer and through the closure panel;
wherein the opening in the backing layer is larger than the portion of the valve that is extended through the opening.

13. The method of claim 11 , wherein the casing includes a first area corresponding to a location of the opening in the backing layer and a second area corresponding with a remainder of the inner surface of the ball.

14. The method of claim 13 , wherein the backing layer lines less than the entire second area of the inner surface of the casing.

15. The method of claim 13 , wherein the backing layer lines the entire second area of the inner surface of the casing.

16. The method of claim 11 , wherein the backing layer is a continuous layer of material; and
wherein the backing layer is discontinuous about the entire periphery of the opening.

17. The method of claim 11 , wherein, upon assembly of the ball, a majority of the piece of material attached to the inside of the closure panel is unattached to the bladder.

18. The method of claim 11 , wherein the piece of material attached to the inside of the closure panel has a size and shape configured to fill the opening in the backing layer.

19. The method of claim 11 , further including attaching the closure panel to panels adjacent to the closure panel by one or more welds.

20. The method of claim 19 , wherein joining the plurality of panels to one another includes welding edges of the plurality of panels to one another.
