Article with thermally bonded ribbon structure and method of making

1. A method of manufacturing an upper for an article of footwear, the method comprising:

dispensing ribbon from a multi-function apparatus that includes a ribbon feeder and an ultrasonic horn, wherein the ribbon is dispensed from a ribbon dispensing outlet of the ribbon feeder in an overlapping pattern of ribbon sections to form a ribbon structure and wherein the ultrasonic horn is attached to the ribbon feeder at a fixed distance from the ribbon dispensing outlet; and

thermally joining a first ribbon section to an underlying material using the ultrasonic horn of the multi-function apparatus.

2. The method of claim 1 , wherein the ribbon is dispensed from the ribbon feeder in a first direction; and

wherein the thermal joining is performed by the ultrasonic horn that follows behind the ribbon feeder in the first direction.

3. The method of claim 1 , wherein

an energy applying tip of the ultrasonic horn performs the thermal joining of the first ribbon section proximate to the ribbon dispensing outlet.

4. The method of claim 1 , wherein the underlying material is a second segment of the ribbon.

5. The method of claim 1 , wherein the thermal joining includes selectively applying ultrasonic energy to the first ribbon section at overlapping regions where the first ribbon section overlaps additional ribbon sections in the pattern.

6. The method of claim 1 , wherein the underlying material is a mesh.

7. The method of claim 1 , wherein dispensing the ribbon includes removing the ribbon from a reel of the ribbon feeder; and

wherein the method further includes continuous removal of release paper from the ribbon as the ribbon is removed from the reel while the ribbon is being dispensed.

8. The method of claim 1 , further including stitching the ribbon to the underlying material after dispensing the ribbon and prior to the thermal joining of the ribbon to the underlying material.

9. The method of claim 1 , further comprising selectively joining portions of the first ribbon section to the underlying material such that at least one span of the first ribbon section remains unattached to the underlying material.

10. A method of manufacturing an upper for an article of footwear, the method comprising:

forming a ribbon structure including a plurality of ribbon sections arranged in an overlapping pattern, the plurality of ribbon sections including a first set of ribbon sections and a second set of ribbon sections;

wherein forming the ribbon structure includes dispensing the plurality of ribbon sections from a multi-function apparatus that includes a ribbon feeder and an ultrasonic horn, wherein the plurality of ribbon sections are dispensed from a ribbon dispensing outlet of the ribbon feeder and wherein the ultrasonic horn is attached to the ribbon feeder at a fixed distance from the ribbon dispensing outlet; and

selectively, thermally joining the first set of ribbon sections to the second set of ribbon sections using the ultrasonic horn of the multi-function apparatus.

11. The method of claim 10 , further comprising selectively joining portions of the first set of ribbon sections to the second set of ribbon sections such that at least one span of ribbon from the first set ribbon sections remains unattached to the second set of ribbon sections.

12. The method of claim 10 , wherein the plurality of ribbon sections are dispensed from the ribbon feeder in a first direction; and

wherein the thermal joining is performed by the ultrasonic horn that follows behind the ribbon feeder in the first direction.

13. The method of claim 10 , further including fixedly attaching one or more of the plurality of ribbon sections to an underlying mesh layer.

14. The method of claim 13 , further including stitching the ribbon to underlying material after dispensing the ribbon and prior to the thermal joining of the ribbon to the underlying material.

15. The method of claim 10 ,

wherein an energy applying tip of the ultrasonic horn performs the thermal joining of the plurality of ribbon sections proximate to the ribbon dispensing outlet.

16. A method of manufacturing an upper for an article of footwear, the method comprising:

forming a ribbon structure including a plurality of ribbon sections including a first set of ribbon sections and a second set of ribbon sections arranged in an overlapping pattern to form a plurality of overlapping regions;

wherein forming the ribbon structure includes dispensing the plurality of ribbon sections from a multi-function apparatus that includes a ribbon feeder and an ultrasonic horn, wherein the plurality of ribbon sections are dispensed from a ribbon dispensing outlet of the ribbon feeder and wherein the ultrasonic horn is attached to the ribbon feeder at a fixed distance from the ribbon dispensing outlet; and

selectively, thermally joining the first set of ribbon sections to the second set of ribbon sections with thermal joining using the ultrasonic horn of the multi-function apparatus;

wherein the plurality of ribbon sections are translucent and have a first opacity;

wherein the overlapping regions have a second opacity that is greater than the first opacity.

17. The method of claim 16 , further comprising selectively joining portions of the first set of ribbon sections to the second set of ribbon sections such that at least one span of ribbon from the first set ribbon sections remains unattached to the second set of ribbon sections.

18. The method of claim 16 , wherein the plurality of ribbon sections are dispensed from the ribbon feeder in a first direction; and

wherein the thermal joining is performed by the ultrasonic horn that follows behind the ribbon feeder in the first direction.

19. The method of claim 16 , further including fixedly attaching one or more of the plurality of ribbon sections to an underlying mesh layer.

20. The method of claim 19 ,

wherein the method further includes stitching the ribbon to underlying material after dispensing the ribbon and prior to the thermal joining of the first set of ribbon sections to the second set of ribbon sections.
