of wefts in between successive weft binder yarns in the paper side layer within the fabric weave pattern repeat. In a regular fabric, the number of intervening wefts is constant; in an irregular fabric the number of intervening wefts is not constant.
The terms xe2x80x9csymmetryxe2x80x9d and xe2x80x9casymmetryxe2x80x9d, and the associated terms xe2x80x9csymmetricalxe2x80x9d and xe2x80x9casymmetricalxe2x80x9d, refer to the shape of the path occupied by a weft binder yarn as it exits the paper side layer, interlaces with a machine side layer warp, and returns to the paper side layer. The path is symmetrical when the interlacing point is located substantially at the middle of the path.
The terms xe2x80x9cevenxe2x80x9d and xe2x80x9cunevenxe2x80x9d refer to the location of the interlacing points between a weft binder yarn and a machine side layer warp inGujarat, whom he served many years before enemies intrigued against him and he was imprisoned in the fortress of Gwalior.
