<p>A belt used as a rope which as a strength higher than that of a rope of the same mass and a substantially circular cross section, and which is provided at both sides thereof with belt portions. This belt consists of a narrow woven material (10) composed of warp and weft yarn (6, 7) of synthetic fiber filaments, and has a belt body (2) extending in the lengthwise direction of the belt, a belt portion (4), and a joint portion (3) for connecting the belt body (2) and belt portion (4) together. The belt body (2) is formed by weaving core strings (5) into a hollow weave texture, and the warp yarn density factor of a hollow weave member (22) is set to not more than 0.700. The belt portion (4) has a woven structure in which the warp yarn (6) in the hollow weave member of the belt body (2) and a part or the whole of the core strings (5) in the belt body (2) are interlaced with the weft yarn. The belt portion has a width W not less than 2.0 times as large as that W of the belt body (2). The joint portion (3) is formed so that it transmutes to a woven structure of the belt body (2) or that of the belt portion (4) in a plurality of steps with its weaving width gradually decreasing or increasing. <IMAGE></p> |
