Abstract

A shaping method for a woven fabric having a hollow looped portion includes the steps of laying top longitudinals and bottom longitudinals in a pattern corresponding to a shape and size of the hollow looped portions, forming top warps and bottom warps in a generally planar pattern, flat weaving a weft through and between the top warps and the bottom warps such that the top warps reside above the weft and said bottom warps reside below the weft, passing the weft between the top longitudinals and the bottom longitudinals in the hollow looped portion such that the top longitudinals reside above the weft and the bottom longitudinals reside below the weft.

Claims

1. A shaping method for a woven fabric having a hollow looped portion, the shaping method comprising:

laying top longitudinals and bottom longitudinals in a pattern corresponding to a shape and size of the hollow looped portion, the top longitudinals being offset from and in spaced relation to the respective adjacent bottom longitudinals;

forming top warps and bottom warps in a generally planar pattern, the top warps being offset from and in spaced relation to the respective adjacent bottom warps;

flat weaving a weft through and between said top warps and said bottom warps such that said top warps reside above said weft and said bottom warps reside below said weft;

passing said weft between said top longitudinals and said bottom longitudinals in said hollow looped portion such that said top longitudinals reside above said weft and said bottom longitudinals reside below said weft;

returning said weft from said hollow looped portion toward said top warps and said bottom warps;

weaving said weft through said top warps and said bottom warps such that said top warps reside below said weft and such that said bottom warps reside above said weft;

returning said weft toward said hollow looped portion; and

weaving said weft through said top longitudinals and said bottom longitudinals such that said top longitudinals reside below said weft and such that said bottom longitudinals reside above said weft.
