Abstract

A method of manufacturing an article may include positioning a first textile sheet against a second textile sheet and reciprocating a single needle of an embroidery machine through the first textile sheet and the second textile sheet, the needle forcing fibers of the second textile sheet through the first textile sheet. The fibers may have terminal ends extending outward of an exterior side of the first textile sheet through which the fibers are forced. A method may include forcing fibers from a second side to an opposite side of a single textile sheet to create a pattern of the fibers on the opposite side. Various articles such as footwear uppers may be manufactured according to the method.

First claim

What is claimed is:

1. A method of manufacturing an article, the method comprising:
positioning a first textile sheet against a second textile sheet;
stitching an outline of a predetermined pattern on the first textile sheet using a threaded needle;
after stitching the outline, controlling an embroidery machine such that the embroidery machine reciprocates a single unthreaded needle supported by a needle drive of the embroidery machine through the first textile sheet and the second textile sheet, wherein the reciprocating single unthreaded needle is within the outline and forces fibers of the second textile sheet through the first textile sheet so that the fibers of the second textile sheet are arranged in the predetermined pattern at the first textile sheet and have terminal ends extending outward of an exterior side of the first textile sheet through which the fibers of the second textile sheet are forced; and
wherein the reciprocating single unthreaded needle does not create stitches.

2. The method of manufacturing of claim 1 , wherein the reciprocating single unthreaded needle has a notched shaft defining barbs extending toward a tip of the reciprocating single unthreaded needle and the reciprocating single unthreaded needle pushes fibers of the second textile sheet through the first textile sheet.

3. The method of manufacturing of claim 1 , wherein the reciprocating single unthreaded needle has a notched shaft defining barbs extending away from a tip of the reciprocating single unthreaded needle and the reciprocating single unthreaded needle pulls fibers of the second textile sheet through the first textile sheet.

4. The method of manufacturing of claim 1 , further comprising:
after controlling the embroidery machine such that the embroidery machine reciprocates the single unthreaded needle within the outline, cutting along or outside of the outline.

5. A method of manufacturing an article, the method comprising:
positioning a first textile sheet against a second textile sheet; and
controlling an embroidery machine such that the embroidery machine reciprocates a single unthreaded needle supported by a needle drive of the embroidery machine through the first textile sheet and the second textile sheet, the reciprocating single unthreaded needle forcing fibers of the second textile sheet through the first textile sheet so that the fibers are arranged in a predetermined pattern at the first textile sheet;
wherein the fibers have terminal ends extending outward of an exterior side of the first textile sheet through which the fibers are forced.

6. The method of manufacturing of claim 5 , wherein the reciprocating single unthreaded needle has a notched shaft defining barbs extending toward a tip of the reciprocating single unthreaded needle and the reciprocating single unthreaded needle pushes fibers of the second textile sheet through the first textile sheet.

7. The method of manufacturing of claim 5 , wherein the reciprocating single unthreaded needle has a notched shaft defining barbs extending away from a tip of the reciprocating single unthreaded needle and the reciprocating single unthreaded needle pulls fibers of the second textile sheet through the first textile sheet.

8. The method of manufacturing of claim 5 , wherein the reciprocating single unthreaded needle does not create stitches.

9. The method of manufacturing of claim 5 , wherein the fibers have terminal ends extending outward of an exterior side of the first textile sheet through which the fibers are forced.
