Abstract

Header assemblies generally used to handle yarns, for example, to facilitate connection of yarns feeding into a tufting machine or other device. In some embodiments, the improved header assembly includes at least a detachable header and a collector plate. The improved header assembly simplifies the process of loading yarn through a detachable header by positioning the detachable header so that it abuts the collectable plate so that individual yarns can be blown through the collector plate through the appropriate holes in the detachable header. In some embodiments, the header assemblies are configured for use with varying gauges, different alignment requirements, different devices, and/or to otherwise be more universal in nature.

Claims

1. A header assembly comprising:

a collector plate comprising collector plate holes;

a face plate coupled with the collector plate and comprising face plate holes, each of the face plate holes aligned with a respective collector plate hole and configured to receive a respective yarn fed through a respective flexible tube; and

a detachable header comprising detachable header holes, the detachable header holes arranged in a plurality of rows staggered from one another and the detachable header detachably secured against the face plate such that at least some of the detachable header holes align with the face plate holes and the collector plate holes.

2. The header assembly of claim 1, wherein the detachable header comprises alignment notches that correspond to at least some of the detachable header holes.

3. The header assembly of claim 1, wherein, when the detachable header and the face plate are secured against one another so that at least some of the detachable header holes align with the face plate holes, the respective yarn received through each face plate hole is blown through the face plate hole directly through one of the detachable header holes.

4. The header assembly of claim 1, wherein the face plate holes and the detachable header holes are arranged in a pattern such that the header assembly is compatible with tufting machines having different gauges.

5. The header assembly of claim 1, wherein the collector plate holes are at least one of graduated or chamfered.

6. The header assembly of claim 1, further comprising a retaining mechanism for releaseably securing the detachable header to the face plate.

7. An assembly comprising:

a collector plate comprising plate holes, wherein a projection projects from at least some of the plate holes, the projection configured to releaseably attach to a respective tube and receive a yarn from the respective tube; and

a detachable header comprising detachable header holes,

wherein the detachable header holes and the plate holes are arranged in a pattern such that when the detachable header abuts the collector plate, at least some of the detachable header holes align with the plate holes.

8. The assembly of claim 7, wherein the detachable header comprises alignment notches that correspond to at least some of the detachable header holes.

9. The assembly of claim 8, wherein the alignment notches also correspond to at least some holes associated with a burn rack.

10. The assembly of claim 7, wherein, when the detachable header and the collector plate abut one another so that at least some of the detachable header holes align with the plate holes, the yarn received from the respective tube is blown through one of the plate holes directly through one of the detachable header holes.

11. The assembly of claim 7, wherein the plate holes generally form at least one generally horizontal row.

12. The assembly of claim 7, wherein the detachable header holes generally form at least one generally horizontal row.

13. The assembly of claim 7, further comprising a retaining mechanism for releaseably securing the detachable header to the collector plate.

14. The assembly of claim 7, wherein the plate holes are at least one of graduated or chamfered.

15. A method comprising:

moving each of a plurality of yarns from a yarn source, wherein each respective yarn is moved through a respective tube terminating at a respective hole in a collector plate, and through a respective hole in a detachable header, the detachable header detachably secured directly against the collector plate, the holes in the detachable header arranged in a plurality of rows staggered from one another;

detaching the detachable header; and

attaching the detachable header at a burn rack such that the plurality of yarns extend through the holes of the detachable header in aligned positions for attachment to other yarns at the burn rack.

16. The method of claim 15, further comprising positioning at least some of the yarns using a plurality of alignment notches of the detachable header, wherein the aligned notches are spaced in a predetermined manner based on the burn rack configuration.

17. The method of claim 15, wherein each respective yarn being moved from the yarn source and through the respective tube terminating at the respective hole in the collector plate comprises moving each respective yarn from the yarn source and through the respective tube terminating at a projection projecting from the respective hole in the collector plate.

18. The method of claim 15, wherein the holes in the collector plate are at least one of graduated or chamfered.
