Abstract

A method of making an article of footwear with an upper including a ribbon structure is disclosed. The method includes laying down ribbon elements in straight and winding sections. The method includes stitching or otherwise attaching the ribbon elements to a backing layer. The method also includes embroidering a periphery of the ribbon structure to tack down any raised portions of the ribbon at the periphery. The method also includes inserting a lace through loops in the ribbon structure.

Claims

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

laying down a continuous ribbon element on a backing layer, wherein laying down the continuous ribbon element includes laying down a straight ribbon section and a curved ribbon section;

stitching the continuous ribbon element in place; and

embroidering a border element over the curved ribbon section;

wherein stitching the continuous ribbon element includes forming a raised portion in the curved ribbon section that rises a first height above the backing layer; and

wherein embroidering the border element over the curved ribbon section pushes down the raised portion to a second height above the backing layer, wherein the second height is less than the first height.

2. The method according to claim 1, wherein embroidering the border element includes forming the border element with a third height above the backing layer;

and

wherein the third height is greater than or equal to the first height.

3. The method according to claim 1, wherein the border element has a stitch height equal to the second height.

4. The method according to claim 1, wherein before the border element is embroidered over the curved ribbon section, a peripheral portion of the upper has a first surface geometry, and wherein after the border element is embroidered over the curved ribbon section, the peripheral portion has a second surface geometry that is smoother than the first surface geometry.

5. The method according to claim 1, wherein the continuous ribbon element is laid down into a ribbon structure having a peripheral portion, and wherein the curved ribbon section is disposed at the peripheral portion.

6. A method of making an upper for an article of footwear, comprising:

laying down a continuous ribbon element on a backing layer, wherein laying down the continuous ribbon element includes laying down an open loop portion of the continuous ribbon element, the open loop portion comprising a first straight ribbon section, a second straight ribbon section, and a curved ribbon section;

stitching the continuous ribbon element in place; and

embroidering an embroidered portion across the first straight ribbon section and the second straight ribbon section; and

wherein the curved ribbon section is spaced apart from the embroidered portion.

7. The method according to claim 6, wherein stitching the continuous ribbon element includes forming a raised portion in the curved ribbon section that rises a first height above the backing layer.

8. The method according to claim 6, wherein embroidering the embroidered portion across the first straight ribbon section and the second straight ribbon section stitches the first straight ribbon section and the second straight ribbon section to the backing layer.

9. The method according to claim 8, wherein the method further includes removing the backing layer.

10. The method according to claim 6, wherein the method further includes coupling the upper to a midsole to form the article of footwear.

11. The method according to claim 6, wherein an opening is formed between the curved ribbon section and the embroidered portion, and wherein the method further includes inserting a lace through the opening.

12. The method according to claim 6, wherein the continuous ribbon element is laid down into a ribbon structure having a peripheral portion, and wherein the curved ribbon section is disposed at the peripheral portion.

13. A method of making an upper for an article of footwear, comprising:

laying down a continuous ribbon element on a backing layer to form a first open loop portion;

stitching the first open loop portion to the backing layer;

laying down the continuous ribbon element on the first open loop portion to form a second open loop portion; and

stitching the second open loop portion onto the first open loop portion so that the second open loop portion is stitched through the first open loop portion and the backing layer.

14. The method according to claim 13, wherein the first open loop portion and the second loop portion are overlapping portions of the continuous ribbon element.

15. The method according to claim 13, wherein the method includes forming a ribbon structure from the continuous ribbon element, the ribbon structure including the first open loop portion and the second open loop portion, and wherein the first open loop portion and the second open loop portion are disposed on a peripheral portion of the ribbon structure.

16. The method according to claim 15, wherein the method further includes embroidering the peripheral portion of the ribbon structure to the backing layer.

17. The method according to claim 16, wherein embroidering the peripheral portion comprises forming an embroidered element over the first open loop portion and the second open loop portion.

18. The method according to claim 15, wherein the method further includes inserting a lace through the first open loop portion and the second open loop portion.

19. The method according to claim 13, wherein the method includes forming a ribbon structure from the continuous ribbon element, the ribbon structure comprising a first layer and a second layer, the first layer being continuously connected with the second layer, and wherein the first layer includes the first open loop portion and wherein the second layer includes the second open loop portion.
