Abstract

An apparatus for manufacturing a sport ball may include a first component having a first baseplate and a plurality of support structures extending from the first baseplate and a second component having a second baseplate and a plurality of welding dies extending from the second baseplate. The apparatus may be configured such that, when the first component is assembled with the second component, each of the plurality of welding dies extending from the second baseplate of the second component aligns with one of the support structures extending from the first baseplate of the first component. In addition, the apparatus may be further configured to compress edges of casing panels against one another between the welding dies and the support structures. Further, the second component may be configured to supply welding energy to edges of casing panels when the casing panels are compressed between the welding dies and the support structures.

Claims

1. An apparatus for manufacturing a sport ball, the apparatus comprising:

a first component having a first baseplate and a plurality of support structures extending from the first baseplate;

wherein a first one of the plurality of support structures has a first height;

wherein a second one of the plurality of support structures has a second height that is less than the first height; and

a second component having a second baseplate and a plurality of welding dies extending from the second baseplate;

wherein a first one of the plurality of welding dies has a third height;

wherein a second one of the plurality of welding dies has a fourth height that is greater than the third height;

wherein the first component is disposed adjacent to the second component such that the first one of the plurality of support structures aligns with the first one of the plurality of welding dies and the second one of the plurality of support structures aligns with the second one of the plurality of welding dies; and

wherein the second component is configured to supply welding energy to the sport ball when the sport ball is compressed between the plurality of welding dies and the plurality of support structures.

2. The apparatus of claim 1, wherein the apparatus is configured to weld multiple seams of the sport ball simultaneously.

3. The apparatus of claim 2, wherein the apparatus is configured to weld five seams of the sport ball simultaneously.

4. The apparatus of claim 1, wherein the second component is configured to supply radio frequency energy to heat the sport ball between the plurality of support structures and the plurality of welding dies.

5. The apparatus of claim 1, wherein at least one of the plurality of support structures includes a support edge and at least one of the plurality of welding dies includes a die edge configured to align with the support edge.

6. A sport ball manufacturing system comprising:

an apparatus including;

a first component having a first baseplate and a plurality of support structures extending from the first baseplate;

wherein a first one of the plurality of support structures has a first height;

wherein a second one of the plurality of support structures has a second height that is less than the first height;

a second component having a second baseplate and a plurality of welding dies extending from the second baseplate;

wherein a first one of the plurality of welding dies has a third height;

wherein a second one of the plurality of welding dies has a fourth height that is greater than the third height;

wherein the first component and the second component are translatable along an axis with respect to one another such that the first one of the plurality of support structures aligns with the first one of the plurality of welding dies and the second one of the plurality of support structures aligns with the second one of the plurality of welding dies; and

a preassembled sport ball casing disposed between and in contact with the first component and the second component;

wherein the preassembled sport ball casing is formed from a plurality of panels temporarily held together by the first component and the second component in an inside-out configuration;

wherein a first one of the plurality of panels has a first edge;

wherein a second one of the plurality of panels has a second edge abutting the first edge to form a first flange portion;

wherein the first flange portion is disposed between the first one of the plurality of support structures and the first one of the plurality of welding dies;

and

wherein the first one of the plurality of welding dies is configured to weld the first edge and the second edge together by applying pressure to the first flange portion against the first one of the plurality of support structures and supplying welding energy to the first flange portion to form a first welded seam.

7. The sport ball manufacturing system of claim 6, wherein a third one of the plurality of panels has a third edge and a fourth one of the plurality of panels has a fourth edge abutting the third edge to form a second flange portion;

wherein the third edge and the fourth edge are disposed between the second one of the plurality of support structures and the second one of the plurality of welding dies;

wherein the second one of the welding dies is configured to weld the third edge and the fourth edge together by applying pressure to the second flange portion against the second one of the plurality of support structures and supplying welding energy to the second flange portion to form a second welded seam such that the first welded seam and the second welded seam are formed simultaneously.

8. The sport ball manufacturing system of claim 7, wherein the preassembled sport ball casing has thirty flange portions and wherein the apparatus is configured to form five welded seams simultaneously.

9. The sport ball manufacturing system of claim 8, wherein the preassembled sport ball casing includes twelve pentagonal panels.

10. The sport ball manufacturing system of claim 6, wherein the first one of the welding dies is configured to supply radio frequency welding energy to the first flange portion.
