Finally, the weft delivery of the RIEMCHENTRANSPORT was replaced by FOUMISSEUR. In order to find a solution of this problem is investigating the factors affecting the width fabric in the direction of warp and weft. The study of the weft direction has a significant impact on this characteristic, namely weft yarn tension and the weft yarn length in weft feeder. The methodology of this research depends on experimental and analytical approach. It is found that there exists an inverse relationship of weft yarn tension and direct relationship of weft delivery length with tape width. Moreover there is an inverse relationship between warp yarn tension and tape width. This research involves the study of the problem that exists in most of the factories, which produce narrow fabrics, especially on the Needle Narrow Weave Machines (NFRQ). This is problem that the width fluctuation for these fabrics. This sector is considered one of the most important sectors of industrial fabric because of its multiple uses that affect industrial economy, whether linked to the textile or other industries. These tapes are used in the manufacture of medical bandages, normal or adhesive, apparel requirements of elastic tape, tapes of the process of decorative embellishment clothing or other uses like special types of electric cables and so on.
