Abstract

A tufting machine utilizing a plurality of yarn ends proceeding through a single needle cooperates with a yarn tension device which selectively applies a different tension to at least one of the plurality of yarn ends proceeding through the needle. Accordingly, a pattern or design can be provided in tufted fabric as the lower tension (higher speed) yarn ends will extend a higher distance from a fabric than lower tension yarn ends.

Claims

1. A tufting machine receiving yarn ends from a yarn supply through a yarn tension device comprising:

a first needle;

a plurality of yarn ends fed from a yarn supply through a yarn tension device to the first needle;

at least one of the plurality of yarn ends fed at least selectively at a higher speed than others of the plurality of yarn ends; and

and a looper mechanism;

wherein the at least one of the yarn ends is selectively tufted to a higher height than the others of the plurality of yarn ends when tufted through a fabric.

2. The tufting machine of claim 1 wherein the looper mechanism further comprises a cut/loop looper.

3. The tufting machine of claim 1 wherein the looper mechanism further comprises a hook.

4. The tufting machine of claim 1 wherein at least one of the plurality of yarn ends fed to the first needle has at least one of a different color and a different texture than the others of the plurality of yarn ends.

5. The tufting machine of claim 1 further comprising a yarn tension device which selectively feeds the at least one of the yarn ends at the higher speed.

6. The tufting machine of claim 5 wherein the yarn tension device independently controls tension on each of the yarn ends proceeding through the needle.

7. The tufting machine of claim 6 wherein the yarn tension device is utilized to create at least one of a design and a repeat by selectively elevating a first yarn end of the plurality of yarn ends, and then a second yarn end of the plurality of yarn ends to create the at least one of the design and the repeat.

8. The tufting machine of claim 6 wherein the yarn tension device further comprises yarn tension device members selectively feeding yarn at at least two speeds to the first needle.

9. The tufting machine of claim 1 further comprising a plurality of needles with the first needle being one of the plurality of needles.

10. A textile machine comprising:

a yarn tensioning device configured to selectively apply tension to a plurality of yarn tension members;

a first needle, said first needle one of a plurality of needles;

a plurality of yarn ends fed from a yarn supply through the yarn tension device to the first needle with at least two of the yarn ends fed from separate yarn tension members;

at least one of the plurality of yarn ends fed at least selectively at a higher speed than others of the plurality of yarn ends; and

and a looper mechanism;

wherein the at least one of the plurality of yarn ends extends a higher height than the others of the plurality of yarn ends when provided through a fabric by the first needle.

11. The textile machine of claim 10 wherein the textile machine is a tufting machine.

12. The textile machine of claim 10 wherein the looper mechanism further comprises at least one of a hook and a cut/loop looper.

13. The textile machine of claim 10 wherein at least one of the plurality of yarn ends fed to the first needle has at least one of a different color and a different texture than the others of the plurality of yarn ends.

14. The tufting machine of claim 10 wherein the yarn tension device is utilized to create at least one of a design and a repeat by selectively elevating a first yarn end of the plurality of yarn ends, and then a second yarn end of the plurality of yarn ends to create the at least one of the design and the repeat.
