Abstract

Hot melt sequins and methods of applying these sequins are disclosed. The sequins may be stitched to a layer of an article in a pattern to form a relatively rigid structure. The sequins may be made of a hotmelt material and melted to form a continuous structure. The sequins may be located along a lacing region and used as eyelets to secure laces.

First claim

What is claimed is:

1. A method of forming a structural component on an article of footwear, comprising:
stitching a plurality of sequins into a predetermined pattern on a substrate layer on each of a medial side and a lateral side of a lacing region of the article of footwear to form the structural component of a lace cage extending in a direction from a toe portion of the article of footwear towards a collar of the article of footwear on each of the medial side and the lateral side, wherein each sequin of the plurality of sequins is the same size and includes a predetermined volume of a hot melt material, and wherein each sequin of the plurality of sequins is a disc-shaped element including a central opening;
wherein, during stitching, each sequin of the plurality of sequins is threaded onto a thread by an embroidery machine from a continuous feed of sequins;
aligning the central opening in each sequin of the plurality of sequins with a corresponding preformed hole in the substrate layer of the article of footwear;
shaping the substrate layer including the stitched plurality of sequins on a last;
heating the plurality of sequins to bond the plurality of sequins to the substrate layer, wherein shaping the substrate layer on the last is performed prior to heating; and
wherein a lace is configured to be inserted through both the central opening in each sequin and the hole in the corresponding preformed hole in the substrate layer, thereby forming the lace cage on the article of footwear.

2. The method according to claim 1 , wherein:
each sequin is comprised of a first layer including the hot melt material and a second layer including at least one different material from the first layer; and
wherein stitching the plurality of sequins on the substrate layer of the article of footwear is followed by melting the first layer to adhere the first layer and the second layer to the substrate layer.

3. The method according to claim 1 , wherein:
the method further comprising melting the plurality of sequins to form the structural component.

4. The method according to claim 1 , wherein the hot melt material is a polyurethane material.

5. The method according to claim 1 , wherein the hot melt material is a thermoplastic polyurethane material.

6. A method of making an article of footwear, comprising:
stitching a plurality of sequins to a substrate layer on each of a medial side and a lateral side of the article of footwear to form a lace cage extending from a toe portion of the article of footwear to a collar of the article of footwear, wherein each sequin of the plurality of sequins is the same size and includes a predetermined volume of a hot melt material, and wherein each sequin of the plurality of sequins is a disc-shaped element including a central opening;
wherein, during stitching, each sequin of the plurality of sequins is threaded onto a thread by an embroidery machine from a continuous feed of sequins;
aligning the central opening in each sequin with a corresponding preformed hole in the substrate layer of the article of footwear;
shaping the substrate layer including the stitched plurality of sequins on a last;
heating the plurality of sequins to bond the plurality of sequins to the substrate layer, wherein shaping the substrate layer on the last is performed prior to heating; and
inserting a lace through the central opening in each sequin and the preformed hole in the substrate layer, thereby forming the lace cage on the article of footwear.

7. The method according to claim 6 , wherein each sequin is comprised of a first layer including the hot melt material and a second layer including at least one different material from the first layer.

8. The method according to claim 6 , wherein stitching each sequin to the substrate layer of the article of footwear includes stitching each sequin to the substrate layer using a thread that extends through the central opening of the sequin and into the substrate layer.

9. The method according to claim 7 , wherein:
wherein stitching each sequin to the article of footwear is followed by melting the first layer to adhere the first layer and the second layer to the substrate layer of the article of footwear.

10. The method according to claim 6 , wherein the hot melt material is a polyurethane material.

11. The method according to claim 6 , wherein the hot melt material is a thermoplastic polyurethane material.

12. The method according to claim 7 , wherein the second layer is comprised of polyurethane.
