Abstract

A method of manufacturing an article may include loading a soluble bobbin thread into an embroidery machine and then driving a needle thread through a base sheet with a needle of the embroidery machine according to a programmed first pattern that provides a series of loops of the needle thread extending outward from a bobbin side of the base sheet. The method may further include bonding the needle thread to a needle side of the base sheet opposite from the bobbin side. A spacer layer may be disposed at the bobbin side of the base sheet, and may be removed after the needle thread is bonded to the base sheet. The loops may be loops of a hook-and-loop fastener or ball control features in various articles manufactured according to the method.

First claim

What is claimed is:

1. A method of manufacturing an article, the method comprising:
loading a soluble bobbin thread into an embroidery machine;
driving a needle thread through a base sheet with a needle of the embroidery machine according to a programmed first pattern that provides a series of loops of the needle thread extending outward from a bobbin side of the base sheet with the soluble bobbin thread engaging the series of loops outward of the bobbin side of the base sheet;
bonding the needle thread to a needle side of the base sheet opposite from the bobbin side of the base sheet; and
applying a solvent to the soluble bobbin thread to dissolve the soluble bobbin thread;
wherein the needle thread is a fusible thread, and wherein bonding the needle thread to the needle side of the base sheet includes applying heat to the needle thread at the needle side of the base sheet.

2. The method of manufacturing of claim 1 , wherein the series of loops is configured as a loop portion of a hook-and-loop fastener.

3. The method of manufacturing of claim 1 , further comprising:
prior to driving the needle thread through the base sheet, disposing one or more spacer layers at the bobbin side of the base sheet so that an inner side of the one or more spacer layers is at the bobbin side of the base sheet;
driving the needle thread through both the base sheet and the one or more spacer layers so that the series of loops extends through the base sheet from the needle side of the base sheet to the bobbin side of the base sheet and into the one or more spacer layers, and the soluble bobbin thread is outward of an outer side of the one or more spacer layers; and
after applying the solvent to the soluble bobbin thread, moving the one or more spacer layers away from the base sheet to slide the one or more spacer layers off of the series of loops.

4. The method of manufacturing of claim 3 , wherein the base sheet is a first base sheet, and the one or more spacer layers are one or more first spacer layers that are a first number of spacer layers and have a first total height, the series of loops is a first series of loops, and the method further comprising:
disposing one or more second spacer layers that are a second number of spacer layers and have a second total height at a bobbin side of a second base sheet so that an inner side of the one or more second spacer layers is at the bobbin side of the second base sheet; wherein the second number of spacer layers is different than the first number of spacer layers, the second total height is different than the first total height, or both;
driving a second needle thread through both the second base sheet and the one or more second spacer layers with the needle of the embroidery machine according to the programmed first pattern or a different programmed pattern that provides a second series of loops of the second needle thread that extends outward from the bobbin side of the second base sheet through the one or more second spacer layers and engages with a second bobbin thread disposed at an outer side of the one or more second spacer layers;
bonding the second needle thread to a needle side of the second base sheet opposite from the bobbin side of the second base sheet;
removing the second bobbin thread; and
moving the one or more second spacer layers away from the second base sheet to slide the one or more second spacer layers off of the second series of loops, the second series of loops having a different height than the first series of loops.

5. The method of manufacturing of claim 1 , further comprising:
applying adhesive to the needle side of the base sheet.

6. The method of manufacturing of claim 1 , wherein the series of loops extends outward from a footwear upper and at least some of the loops are configured as ball control elements or as a strap fastener.

7. The method of manufacturing of claim 1 , wherein the soluble bobbin thread is water soluble and the solvent is water.

8. The method of manufacturing of claim 1 , wherein:
a first group of the loops has a first density and a second group of the loops has a second density different from the first density; and/or
a first set of the loops has a first color and a second set of the loops has a second color different from the first color.

9. The method of manufacturing of claim 1 , wherein the article is a first article, the base sheet is a first base sheet, the needle thread is a first needle thread, and the method further comprising:
driving a second needle thread through a second base sheet with the needle of the embroidery machine to form a second series of loops in a second pattern different than the first pattern in at least one of color, density of the second series of loops, or height of the second series of loops.

10. A method of manufacturing an article, the method comprising:
disposing one or more first spacer layers at a bobbin side of a first base sheet so that an inner side of the one or more first spacer layers is at the bobbin side of the first base sheet;
wherein the one or more first spacer layers are a first number of spacer layers and have a first total height;
driving a first needle thread through both the first base sheet and the one or more first spacer layers with a needle of an embroidery machine according to a programmed first pattern that provides a first series of loops of the first needle thread that extends outward from the bobbin side of the first base sheet through the one or more first spacer layers and engages with a first bobbin thread disposed at an outer side of the one or more first spacer layers;
bonding the first needle thread to a needle side of the first base sheet opposite from the bobbin side of the first base sheet;
removing the first bobbin thread;
moving the one or more first spacer layers away from the first base sheet to slide the one or more first spacer layers off of the first series of loops;
disposing one or more second spacer layers that are a second number of spacer layers and have a second total height at a bobbin side of a second base sheet so that an inner side of the one or more second spacer layers is at the bobbin side of the second base sheet wherein the second number of spacer layers is different than the first number of spacer layers, the second total height is different than the first total height, or both;
driving a second needle thread through both the second base sheet and the one or more second spacer layers with the needle of the embroidery machine according to the programmed first pattern or a different programmed pattern that provides a second series of loops of the second needle thread that extends outward from the bobbin side of the second base sheet through the one or more second spacer layers and engages with a second bobbin thread disposed at an outer side of the one or more second spacer layers;
bonding the second needle thread to a needle side of the second base sheet opposite from the bobbin side of the second base sheet;
removing the second bobbin thread; and
moving the one or more second spacer layers away from the second base sheet to slide the one or more second spacer layers off of the second series of loops, the second series of loops having a different height than the first series of loops.

11. The method of manufacturing of claim 10 , wherein the first series of loops is configured as a loop portion of a hook-and-loop fastener.

12. The method of manufacturing of claim 10 , wherein the first series of loops extends outward from a footwear upper and at least some of the loops of the first series of loops are configured as ball control elements or as a strap fastener.
