Abstract

A multi-carrier, zonal weaving system and method of manufacturing a zonal woven material is provided. The multi-carrier system includes a first weft yarn, a second weft yarn, and one or more intermediate warp yarns for wrapping by the first and second weft yarns. The zonal weaving method includes receiving a first weft yarn from a first origin via a first shed, wrapping it around one or more zonal warp yarns, and returned to the first weft origin after the first shed upper and lower yarns are exchanged. In further aspects, a second weft yarn is received from a second weft origin via a second shed, wrapped around the same intermediate, zonal warp yarns, and returned to the second weft origin after exchange of the second shed yarns. In one aspect, the first and second weft yarns are interlocked during wrapping of the common warp yarns.

First claim

What is claimed is:

1. A zonal weaving device for providing a zonal woven material, the zonal weaving device comprising:
a first carrier on a first side of the zonal weaving device, said first carrier configured to carry a first weft yarn from the first side of the zonal weaving device; and
a second carrier on a second side of the zonal weaving device, said second carrier configured to carry a second weft yarn from the second side of the zonal weaving device, wherein the first side of the zonal weaving device is opposite the second side of the zonal weaving device,
wherein the zonal woven material comprises a first plurality of warp yarns, one or more intermediate warp yarns, and a second plurality of warp yarns, wherein in a first woven row, the first carrier is configured to carry the first weft yarn through a first shed formed from the first plurality of warp yarns to the one or more intermediate warp yarns and wrap around the one or more intermediate warp yarns before returning the first weft yarn to the first side in a second woven row, and wherein in the first woven row, the second carrier is configured to carry the second weft yarn through a second shed formed from the second plurality of warp yarns to the one or more intermediate warp yarns and also wrap around the one or more intermediate warp yarns before returning the second weft yarn to the second side in the second woven row, wherein the one or more intermediate warp yarns are located in between the first plurality of warp yarns and the second plurality of warp yarns forming the woven material.

2. The zonal weaving device of claim 1 , wherein the first carrier comprises a first rapier and the second carrier comprises a second rapier.

3. The zonal weaving device of claim 1 , wherein the first shed formed from the first plurality of warp yarns comprises an upper plurality of warp yarns and a lower plurality of warp yarns.

4. The zonal weaving device of claim 3 , wherein the upper plurality of warp yarns and the lower plurality of warp yarns of the first shed are independently moveable with respect to the first shed and the intermediate warp yarns.

5. The zonal weaving device of claim 1 , wherein the second shed formed from the second plurality of warp yarns comprises an upper plurality of warp yarns and a lower plurality of warp yarns.

6. The zonal weaving device of claim 5 , wherein the upper plurality of warp yarns and the lower plurality of warp yarns of the second shed are independently moveable with respect to the second shed and the intermediate warp yarns.

7. The zonal weaving device of claim 1 , wherein wrapping around the one or more intermediate warp yarns with the first weft yarn via the first shed and the second weft yarn via the second shed comprises interlocking the first weft yarn and the second weft yarn.

8. The zonal weaving device of claim 1 , wherein the one or more intermediate warp yarns form a common warp zone, said common warp zone being adjustable based on one or more of:
1) a number of warp yarns in the common warp zone;
2) a number of warp yarns in the first plurality of warp yarns forming the first shed; and
3) a number of warp yarns in the second plurality of warp yarns forming the second shed.

9. A zonal weaving method for generating a woven material having a common woven zone comprising:
in a first woven row, receiving a first weft yarn from a first side of a weaving loom, said first weft yarn received via a first shed portion comprising a plurality of first upper warp yarns and a plurality of first lower warp yarns;
wrapping the first weft yarn around one or more zonal warp yarns in a first direction;
exchanging a first position of the plurality of first upper warp yarns with a second position of the plurality of first lower warp yarns;
returning the first weft yarn to the first side of the weaving loom without the first weft yarn reaching a second side of the weaving loom in a second woven row;
in the first woven row, receiving a second weft yarn from the second side of the weaving loom, said second weft yarn received via a second shed portion comprising a plurality of second upper warp yarns and a plurality of second lower warp yarns;
wrapping the second weft yarn around the one or more zonal warp yarns in a second direction;
exchanging a third position of the plurality of second upper warp yarns with a fourth position of the plurality of second lower warp yarns; and
returning the second weft yarn to the second side of the weaving loom without the second weft yarn reaching the first side of the weaving loom in the second woven row.

10. The zonal weaving method of claim 9 , wherein the first direction is opposite the second direction.

11. The zonal weaving method of claim 9 , wherein wrapping the second weft yarn around the one or more zonal warp yarns comprises interlocking the second weft yarn with the first weft yarn.

12. The zonal weaving method of claim 9 , wherein the common woven zone comprises the one or more zonal warp yarns wrapped by the first weft yarn and the second weft yarn at alternating rows of weaving.

13. The zonal weaving method of claim 12 , wherein each row of weaving comprises the first shed portion receiving the first weft yarn and the second shed portion receiving the second weft yarn.

14. A zonal woven material comprising:
a first woven portion comprising a plurality of first warp yarns and a first weft yarn;
a second woven portion comprising a plurality of second warp yarns and a second weft yarn;
an intermediate woven zone located between the first woven portion and the second woven portion abutting the first woven portion on a first side of the intermediate woven zone, and abutting the second woven portion on a second side of the intermediate woven zone, wherein the intermediate woven zone comprises one or more intermediate warp yarns wrapped by both, the first weft yarn and the second weft yarn in the same woven row.

15. The zonal woven material of claim 14 , wherein an overall material width of the zonal woven material comprises a first width across the first woven portion, a second width across the second woven portion, and a third width across the intermediate woven zone.

16. The zonal woven material of claim 14 , wherein the overall material width of the zonal woven material is a constant width based on a dynamic width of one or more of the first woven portion and the second woven portion corresponding to a dynamic width of the intermediate woven zone.

17. The zonal woven material of claim 14 , wherein the first weft yarn and the second weft yarn are interlocked at the intermediate woven zone.
