Abstract

A system can comprise a plurality of containers that are coupled together as a movable unit. A plurality of container-feeding assemblies can be configured to simultaneously deliver respective yarns into respective containers of the plurality of containers. A header can be selectively attachable to a tufting machine, the header having a longitudinal axis. A retainer can be configured to extend across the header along the longitudinal axis to secure the respective yarns in respective positions relative to each other along the longitudinal axis.

First claim

What is claimed is:

1. A system comprising:
a plurality of containers that are coupled together as a movable unit; and
a plurality of container-feeding assemblies comprising a plurality of aspirators that are configured to simultaneously deliver respective yarns into respective containers of the plurality of containers,
wherein the movable unit further comprises an adapter plate defining a plurality of openings and a plurality of guide tubes, wherein a respective guide tube of the plurality of guide tubes extends between each opening of the adapter plate and a respective container of the plurality of containers, wherein each aspirator of the plurality of aspirators is positioned at a respective opening of the adapter plate.

2. The system of claim 1 , further comprising:
a header that is configured to receive yarn ends of the yarns in the plurality of containers, the header having a longitudinal axis; and
a retainer that is configured to extend across the header along the longitudinal axis to secure the respective yarns in respective positions relative to each other along the longitudinal axis.

3. The system of claim 1 , wherein each container-feeding assembly of the plurality of container-feeding assemblies comprises:
opposing rollers that bias against opposing sides of the respective yarn; and
at least one motor that is coupled to at least one of the opposing rollers and is configured to cause rotation of the at least one of the opposing rollers.

4. The system of claim 1 , wherein the plurality of containers are see-through.

5. The system of claim 1 , wherein each container is tubular or substantially tubular.

6. The system of claim 1 , wherein each container comprises a flexible sidewall.

7. The system of claim 1 , further comprising at least one yarn metering device that is configured to measure a quantity of yarn delivered into a container of the plurality of containers.

8. The system of claim 7 , wherein the at least one yarn metering device comprises a plurality of yarn metering devices, wherein each yarn metering device of the plurality of yarn metering devices is configured to measure the quantity of yarn delivered into a respective container of the plurality of containers.

9. The system of claim 7 , wherein the at least one metering device comprises a roller.

10. The system of claim 1 , further comprising a pair of opposing drive rollers that are configured to maintain a select tension on yarn leaving a heat set apparatus.

11. The system of claim 1 , further comprising a plurality of plungers, wherein each plunger of the plurality of plungers is configured to reciprocally move inwardly into a respective container to compress yarn within the container.

12. The system of claim 11 , wherein each plunger defines a longitudinal bore therethrough through which a respective yarn can extend.

13. The system of claim 11 , wherein each plunger is configured to intermittently move inwardly into and outwardly from the respective container.

14. The system of claim 11 , wherein each plunger is configured to continuously move inwardly into and outwardly from the respective container.

15. The system of claim 1 , further comprising a heat set apparatus that is configured to deliver the yarns to respective container feed assemblies.

16. A method comprising:
delivering, with a plurality of container-feeding assemblies, a first plurality of yarns into respective containers of a plurality of containers, wherein the plurality of container-feeding assemblies comprise a plurality of aspirators that are configured to simultaneously deliver respective yarns into respective containers of the plurality of containers, wherein the plurality of containers are coupled together as a movable unit, wherein the movable unit further comprises an adapter plate defining a plurality of openings and a plurality of guide tubes, wherein a respective guide tube of the plurality of guide tubes extends between each opening of the adapter plate and a respective container of the plurality of containers, wherein each aspirator of the plurality of aspirators is positioned at a respective opening of the adapter plate;
securing a retainer to a first header to fix the respective yarns of the first plurality of yarns in respective positions relative to each other along the longitudinal axis of the first header;
severing the first plurality of yarns so that each yarn of the first plurality of yarns has a first end within a respective container and an opposing loose end, wherein the retainer is secured to the first header between the first ends and the loose ends of the first plurality of yarns;
positioning the movable unit proximate to a second header of a yarn processing machine, the yarn processing machine having a second plurality of yarns thereon, each yarn of the second plurality of yarns on the yarn processing machine having a respective beginning end;
aligning the first header with the second header so that the loose ends of the first plurality of yarns are aligned with respective beginning ends of the second plurality of yarns on the yarn processing machine; and
coupling respective loose ends of the first plurality of yarns in the containers to respective beginning ends of the second plurality of yarns on the yarn processing machine.

17. The method of claim 16 , wherein the yarn processing machine is one of a tufting machine or a twisting machine.

18. A method comprising:
delivering, with a plurality of container-feeding assemblies, a first plurality of yarns from a heat set apparatus into respective containers of a plurality of containers, wherein the heat set apparatus delivers the first plurality of yarns to respective container-feeding assemblies of the plurality of container-feeding assemblies, wherein the plurality of container-feeding assemblies comprise a plurality of aspirators that are configured to simultaneously deliver respective yarns into respective containers of the plurality of containers, wherein the plurality of containers are coupled together as a movable unit, wherein the movable unit further comprises an adapter plate defining a plurality of openings and a plurality of guide tubes, wherein a respective guide tube of the plurality of guide tubes extends between each opening of the adapter plate and a respective container of the plurality of containers, wherein each aspirator of the plurality of aspirators is positioned at a respective opening of the adapter plate;
securing a retainer to a first header to fix the respective yarns of the first plurality of yarns in respective positions relative to each other along the longitudinal axis of the first header;
severing the first plurality of yarns so that each yarn of the first plurality of yarns has a first end within a respective container and an opposing loose end, wherein the retainer is secured to the first header between the first ends and the loose ends of the first plurality of yarns;
positioning the movable unit proximate to a second header of a yarn processing machine, the yarn processing machine having a second plurality of yarns thereon, each yarn of the second plurality of yarns on the yarn processing machine having a respective beginning end;
aligning the first header with the second header so that the loose ends of the first plurality of yarns are aligned with respective beginning ends of the second plurality of yarns on the yarn processing machine; and
coupling respective loose ends of the first plurality of yarns in the containers to respective beginning ends of the second plurality of yarns on the yarn
