Abstract

An article comprised of tape segments embroidered in place is disclosed. One embodiment includes tape segments embroidered to a self-supporting embroidered structure. Another embodiment includes tape segments embroidered together to form an embroidered lattice structure. In one embodiment, some of the tape segments may expand when exposed to heat and may be used to form cushioning regions for the article.

First claim

What is claimed is:

1. A method of making an upper for an article of footwear, comprising:
embroidering a thread to a backing layer to form a first embroidered region of an embroidered assembly;
laying down a plurality of tape segments in three tape layers, wherein each tape layer is laid down sequentially such that a first tape layer is laid down onto the first embroidered region, a second tape layer is laid down over the first tape layer, and a third tape layer is laid down over the second tape layer;
embroidering a peripheral layer along a periphery of the embroidered assembly over the backing layer, the first tape layer, the second tape layer, and the third tape layer;
embroidering the thread and the plurality of tape segments to the backing layer by passing an embroidery thread through the plurality of tape segments to form a second embroidered region of the embroidered assembly over the first embroidered region and the three tape layers;
removing the backing layer from the embroidered assembly; and
forming the upper of the article of footwear from the embroidered assembly.

2. The method according to claim 1 , wherein the first embroidered region is comprised of thread arranged in a self-supporting embroidered structure.

3. The method according to claim 1 , wherein removing the backing layer comprises dissolving the backing layer.

4. The method according to claim 1 , wherein laying down the plurality of tape segments comprises controlling a continuous tape feed assembly.

5. The method according to claim 4 , further comprising:
placing stitches across the plurality of tape segments to lock the plurality of tape segments on the backing layer using an embroidery device;
wherein the continuous tape feed assembly is configured to continuously feed tape along predetermined locations of the backing layer as the embroidery device places the stitches; and
wherein the embroidery device places the stitches at one or more crossing points between tape segments of different tape layers of the three tape layers.

6. The method according to claim 1 , wherein the second embroidered region is an eyestay portion including one or more eyelets.

7. The method according to claim 6 , wherein two or more tape segments of the plurality of tape segments include an end attached adjacent to an eyelet of the eyestay portion.

8. The method according to claim 7 , wherein tension applied to the eyelet of the eyestay portion is configured to be transferred to the two or more tape segments that include an end attached adjacent to the eyelet.

9. The method according to claim 6 , wherein at least one tape segment of the plurality of tape segments includes an end attached adjacent to at least one eyelet of the eyestay portion.

10. The method according to claim 1 , wherein the three tape layers include a first set of parallel tape segments oriented in a first direction and a second set of parallel tape segments oriented in a second direction, wherein the first direction is perpendicular to the second direction.

11. The method according to claim 1 , wherein embroidering the peripheral layer along the periphery of the embroidered assembly includes filling in the periphery with an embroidered structure.

12. A method of making an upper for an article of footwear, comprising:
embroidering a thread to a backing layer to form a first embroidered region of an embroidered assembly;
laying down tape segments along portions of the backing layer using a continuous tape feed assembly to form a first tape layer;
laying down tape segments onto the first tape layer using the continuous tape feed assembly to form a second tape layer over the first tape layer;
laying down tape segments onto the second tape layer using the continuous tape feed assembly to form a third tape layer over the second tape layer, wherein the first tape layer, the second tape layer, and the third tape layer are laid down sequentially;
placing stitches across the tape segments to lock the tape segments on the backing layer using an embroidery device;
wherein the continuous tape feed assembly is configured to continuously feed tape along predetermined locations of the backing layer as the embroidery device places the stitches;
embroidering a peripheral layer along a periphery of the embroidered assembly over the backing layer, the first tape layer, the second tape layer, and the third tape layer;
embroidering the thread and the tape segments to the backing layer by passing an embroidery thread through the plurality of tape segments to form a second embroidered region of the embroidered assembly;
removing the backing layer from the embroidered assembly; and
forming the upper of the article of footwear from the embroidered assembly.

13. The method according to claim 12 , wherein the tape segments of the first tape layer cross over the tape segments of the second tape layer at one or more crossing points.

14. The method according to claim 13 , wherein placing stitches across the tape segments comprises stitching the tape segments at the one or more crossing points.

15. The method according to claim 13 , wherein the three tape layers include a first set of parallel tape segments oriented in a first direction and a second set of parallel tape segments oriented in a second direction, wherein the first direction is perpendicular to the second direction.

16. The method according to claim 12 , wherein embroidering the peripheral layer along the periphery of the embroidered assembly includes filling in the periphery with an embroidered structure.
