Abstract

A method of forming a plate for an article of footwear includes applying a first strand portion to a base layer including positioning adjacent segments of the first strand portion to form a first layer on the base layer. The adjacent segments of the first strand portion having a greater density across a width of the plate between a medial side and a lateral side at a midfoot region of the plate than at a forefoot region of the plate and at a heel region of the plate. The method also includes applying at least one of heat and pressure to the first strand portion and to the base layer to conform the first strand portion and the base layer to a predetermined shape.

First claim

What is claimed is:

1. A plate for an article of footwear, the plate comprising:
a substrate having a peripheral edge defining a medial side and a lateral side extending between a heel region and a forefoot region;
a first tow of fibers attached to the substrate and including a first pair of segments extending from the heel region to a first location in the forefoot region, the first pair of segments connected to each other by a first looped portion at the first location;
a second tow of fibers attached to the substrate and including a second pair of segments extending from the heel region to a second location in the forefoot region, the second pair of segments connected to each other by a second looped portion at the second location, the second location being closer to an anterior-most point of the substrate than the first location; and
a polymeric resin consolidating the first tow of fibers and the second tow of fibers, the first tow of fibers and the second tow of fibers being joined to each other by the polymeric resin to provide the plate with a smooth outer surface.

2. The plate of claim 1 , wherein the first tow of fibers includes multiple segments that extend from the heel region to the first location and the second tow of fibers includes multiple segments that extend from the heel region to the second location.

3. The plate of claim 2 , wherein the multiple segments of the first tow of fibers and the multiple segments of the second tow of fibers are all part of a same unitary strand.

4. The plate of claim 3 , wherein the multiple segments of the first tow of fibers include a plurality of the first looped portions at the first location where adjacent ones of the multiple segments of the first tow of fibers are connected to one another.

5. The plate of claim 4 , wherein the multiple segments of the second tow of fibers include a plurality of the second looped portions at the second location where adjacent ones of the multiple segments of the second tow of fibers are connected to one another.

6. The plate of claim 3 , wherein the multiple segments of the second tow of fibers include a plurality of the second looped portions at the second location where adjacent ones of the multiple segments of the second tow of fibers are connected to one another.

7. The plate of claim 1 , wherein the first pair of segments are separated from each other at the peripheral edge of the substrate.

8. The plate of claim 7 , wherein the second pair of segments are separated from each other at the peripheral edge of the substrate.

9. The plate of claim 1 , wherein the first tow of fibers and the second tow of fibers include at least one of carbon fibers, boron fibers, glass fibers, and polymeric fibers.

10. An article of footwear comprising the plate of claim 1 .

11. A plate for an article of footwear, the plate comprising:
a substrate having a peripheral edge defining a medial side and a lateral side extending between a heel region and a forefoot region;
a first tow of fibers attached to the substrate and extending between a first looped portion disposed at a first location in the forefoot region and a second looped portion disposed at a second location in the heel region;
a second tow of fibers attached to the substrate and extending between a third looped portion disposed at the first location in the forefoot region and a fourth looped portion disposed at the second location in the heel region, the third looped portion being aligned with the first looped portion at the first location along a first transverse axis extending perpendicular to a longitudinal axis of the substrate and between the medial side and the lateral side and the second looped portion being aligned with the fourth looped portion at the second location along a second transverse axis (i) extending perpendicular to the longitudinal axis of the substrate, (ii) between the medial side and the lateral side, and (iii) parallel to the first transverse axis; and
a polymeric resin consolidating the first tow of fibers with the second tow of fibers, wherein the first tow of fibers and the second tow of fibers are joined to the substrate by the polymeric resin.

12. The plate of claim 11 , wherein the first tow of fibers includes multiple segments that extend between the first location and the second location and the second tow of fibers includes multiple segments that extend between the first location and the second location.

13. The plate of claim 12 , wherein the multiple segments of the first tow of fibers and the multiple segments of the second tow of fibers are all part of a same unitary strand.

14. The plate of claim 11 , wherein the first tow of fibers and the second tow of fibers include at least one of carbon fibers, boron fibers, glass fibers, and polymeric fibers.

15. An article of footwear comprising the plate of claim 11 .
