Abstract

An upper for an article of footwear may have material layers and a plurality of strand segments. The material layers are located adjacent to each other and in an overlapping configuration, and the material layers are located in a lace region and a lower region of the upper. The strand segments extend from the lace region to the lower region. The strand segments may be located and secured between the material layers in the lace region and the lower region. The strand segments may form both an exterior surface of the upper and an opposite interior surface of the upper in an area between the lace region and the lower region. The material layers may define an opening between the lace region and the lower region, and the strand segments extend across the opening.

Claims

1. A method of manufacturing an article of footwear having an upper and a sole structure, the method comprising:

positioning a base material layer on an assembly apparatus, a plurality of first pegs of the assembly apparatus protruding through a first area of the base material layer, and a plurality of second pegs of the assembly apparatus protruding through a second area of the base material layer;

locating a strand adjacent to a surface of the base material layer and around the first pegs and the second pegs, the strand extending from the first area of the base material layer to the second area of the base material layer;

securing the strand to the base material layer; and

incorporating the strand and the base material layer into the upper, the first area being located in a lace region of the upper, and the second area being located in a lower region of the upper, the lower region being spaced from the lace region and located proximal to an area for securing the sole structure to the upper.

2. The method recited in claim 1, further including a step of defining apertures in the base material layer, and the step of positioning including extending the pegs through the apertures.

3. The method recited in claim 2, further including a step of extending a lace through the apertures.

4. The method recited in claim 1, wherein the step of positioning includes defining an opening in the base material layer located between the first area and the second area, and the step of locating includes extending the strand across the opening.

5. The method recited in claim 4, wherein the step of incorporating includes positioning the opening in a side area of the upper.

6. The method recited in claim 1, wherein the step of locating includes alternating the strand from (a) passing around one of the first pegs and (b) passing around one of the second pegs.

7. The method recited in claim 1, wherein the step of locating includes alternating the strand from (a) passing around two of the first pegs and (b) passing around at least one of the second pegs.

8. The method recited in claim 1, wherein the step of securing includes stitching portions of the strand to the base material layer.

9. The method recited in claim 1, wherein the step of securing includes bonding a cover material layer to the surface of the base material layer, the strand being located between the base material layer and the cover material layer.

10. The method recited in claim 1, wherein the step of incorporating includes positioning portions of the strand located between the lace region and the lower region on an exterior of the article of footwear.

11. A method of manufacturing an article of footwear having an upper and a sole structure, the method comprising:

providing a base material layer having a first area, a second area spaced from the first area, and an opening located between the first area and the second area, and the base material layer defining a plurality of apertures in at least the first area;

positioning the base material layer on an assembly apparatus, a plurality of first pegs of the assembly apparatus protruding through the apertures in the first area of the base material layer, and a plurality of second pegs of the assembly apparatus protruding through the second area of the base material layer;

locating a strand adjacent to a surface of the base material layer and around the first pegs and the second pegs, multiple segments of the strand extending from the first area of the base material layer to the second area of the base material layer, and the segments of the strand extending across the opening;

securing the strand to the base material layer; and

incorporating the strand and the base material layer into a side area of the upper, the first area being located in a lace region of the upper, and the second area being located in a lower region of the upper, the lower region being spaced from the lace region and located proximal to an area for securing the sole structure to the upper.

12. The method recited in claim 11, further including a step of extending a lace through the apertures.

13. The method recited in claim 11, wherein the step of locating includes forming loops of the strand around at least some of the first pegs, and further including a step of extending a lace through the apertures and the loops.

14. The method recited in claim 11, wherein the step of locating includes alternating the strand from (a) passing around one of the first pegs and (b) passing around one of the second pegs.

15. The method recited in claim 11, wherein the step of locating includes alternating the strand from (a) passing around two of the first pegs and (b) passing around at least one of the second pegs.

16. The method recited in claim 11, wherein the step of securing includes stitching portions of the strand to the base material layer.

17. The method recited in claim 11, wherein the step of securing includes bonding a cover material layer to the surface of the base material layer, the strand being located between the base material layer and the cover material layer.

18. The method recited in claim 11, wherein the step of incorporating includes positioning the segments of the strand extending across the opening on an exterior of the article of footwear.

19. The method recited in claim 11, further including a step of providing the strand to have an outer sheath that extends around an inner core, the sheath and the core extending along a length of the strand segments, and each of the sheath and the core being formed from a plurality of intertwined threads.

20. The method recited in claim 11, further including a step of locating another strand adjacent to an opposite surface of the base material layer, the another strand extending from the first area of the base material layer to the second area of the base material layer, and segments of the another strand extending across the opening.

21. The method recited in claim 20, further including a step of angling the segments of the another strand with respect to the segments of the strand.

22. A method of manufacturing an article of footwear having an upper and a sole structure, the method comprising:

positioning an upper element on an assembly apparatus, a plurality of pegs of the assembly apparatus protruding through the upper element;

locating a strand adjacent to a surface of the upper element, a plurality of loops of the strand extending and around the pegs;

securing the strand to the upper element;

incorporating the strand and the upper element into the upper; and

extending a lace through the loops.

23. The method recited in claim 22, wherein the step of positioning includes extending the pegs through apertures in the upper element.

24. The method recited in claim 23, wherein the step of locating includes forming the loops around the apertures.

25. The method recited in claim 23, wherein the step of extending includes passing the lace through the apertures and the loops of the strand.

26. The method recited in claim 22 wherein the step of locating includes forming the loops of the strand around one of the pegs.

27. The method recited in claim 22, wherein the step of locating includes forming the loops of the strand around two of the pegs.

28. The method recited in claim 22, wherein the step of securing includes stitching portions of the strand to the upper element.

29. The method recited in claim 22, wherein the step of securing includes bonding a cover material layer to the surface of the upper element, the strand being located between the upper element and the cover material layer.

30. The method recited in claim 22, wherein the step of incorporating includes (a) positioning the loops in a lace region of the upper and (b) positioning portions of the strand in a lower region of the upper, the lower region being spaced from the lace region and located proximal to an area for securing the sole structure to the upper.

31. The method recited in claim 30, wherein the upper element defines an opening between the lace region and the lower region.
