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.
Claims16
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 is slidably located below the fill fiber;
- wherein the weave control grid has an open central section and a plurality of warp fiber openings surrounding the open central section, the plurality of warp fiber openings including openings for warp fibers to be added during changes in contour or size of the woven structure.
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 the 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 is slidably located below the fill fiber wand;
- wherein the weave control grid has an open central section and a plurality of warp fiber openings surrounding the open central section, the plurality of warp fiber openings including openings for warp fibers to be added during changes in contour or size of the woven structure.
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 is slidably located below the fill fiber wand;
- wherein the weave control grid has an open central section and a plurality of warp fiber openings surrounding the open central section, the plurality of warp fiber openings including openings for warp fibers to be added during changes in contour or size of a woven structure.
