Abstract

Disclosed is a weaving method including placing a first section of a fill fiber between warp fibers, forming a pick, moving a base to reposition the warp fibers, and placing a second section of the fill fiber between the warp fibers to form a woven structure, wherein at least a portion of the warp fibers are introduced to the woven structure using a weave control grid. Also disclosed is a weaving assembly including a base, a base positional controller, a weave control grid, warp fiber arms, a warp fiber arm positional controller and a fill fiber wand.

Claims (36)

1. A weaving method comprising:

placing a first section of a fill fiber between warp fibers,

forming a pick,

moving a base to reposition the warp fibers, and

placing a second section of the fill fiber between the warp fibers to form a woven structure,

wherein at least a portion of the warp fibers are introduced to the woven structure using a weave control grid;

wherein the weave control grid has an open central section; and

wherein the weave control grid is modular to permit changes to a size and shape of the open central section to accommodate changes in a size and shape of the evolving woven structure.

2. The weaving method of claim 1 , wherein at least a portion of the warp fibers are secured to the base.

3. The weaving method of claim 1 , wherein the weave control grid is affixed to the base.

4. The weaving method of claim 1 , wherein the weave control grid is slidably located below the fill fiber.

5. A weaving method comprising:

forming a first pick,

repositioning warp fibers by moving warp fiber arms relative to a fill fiber wand, or repositioning warp fibers by moving a base relative to the fill fiber wand, or both and

forming a second pick after repositioning warp fibers to produce a woven structure,

wherein at least a portion of the warp fibers extend from one of the warp fiber arms to the base and at least a portion of the warp fibers are introduced to the woven structure using a weave control grid;

wherein the weave control grid has an open central section; and

wherein the weave control grid is modular to permit changes to a size and shape of the open central section to accommodate changes in a size and shape of the evolving woven structure.

6. The weaving method of claim 5 , further comprising repositioning the weave control grid relative to the fill fiber wand.

7. The weaving method of claim 5 , wherein warp fibers are positioned by the weave control grid prior to forming the first pick or second pick.

8. The weaving method of claim 5 , wherein the weave control grid is attached to the base.

9. A weaving assembly comprising:

a base,

a base positional controller,

a weave control grid,

warp fiber arms,

a warp fiber arm positional controller and

a fill fiber wand;

wherein the weave control grid has an open central section; and

wherein the weave control grid is modular to permit changes to a size and shape of the open central section to accommodate changes in a size and shape of an evolving woven structure.

10. The weaving assembly of claim 9 , further comprising a holding station.

11. The weaving assembly of claim 10 , wherein the holding station is a secondary weave control grid.

12. The weaving assembly of claim 9 , wherein the weave control grid is slidably located below the fill fiber wand.

13. The weaving assembly of claim 12 , wherein a location of the weave control grid is controlled by a positional controller.

14. The weaving assembly of claim 9 , wherein the weave control grid has openings with variable spacing between openings.

15. The weaving assembly of claim 9 , further comprising additional weave control grids.
