Multi-layered woven belt with rope shaped portion
First Claim
1. A thick belt comprising at least four layers of weave structure including two outer layers and at least two remaining inner layers,said two outer layers being woven into a hollow tube by a common weft and said at least two remaining inner layers being woven by a second weft,the belt having a width and a weave structure providing a rope cross-sectionally shaped portion in a central area thereof,said central area having a cross-sectional shape corresponding to a cross-sectional shape of a rope,a cross-sectional thickness of said central area being greater than one quarter of the belt width.

Abstract
A woven belt having thick and narrow portions with a breaking strength per unit width that exceeds the level of strength of conventional fabric straps and belts. One embodiment of the belt includes at least four layers of weave structure in which two outer layers are woven into a hollow tube by a common weft and the remaining inner layers are woven together by a second weft. The widthwise central area of the belt is provided with a thickness that is larger than a quarter of the belt width.

5. A thick belt comprising at least two layers of weave structure, the thick belt having a width and characterized in that an effective thickness of a warp bundle is greater than 2.5 mm and the belt having a thickness greater than 6.0 mm except for selvage areas, the effective thickness of the warp bundle being a function of the total denier of all warps used in said belt and calculated based on the total denier of all warps used in said belt in accordance with the following formula:
-
space="preserve" listing-type="tabular">______________________________________ effective thickness of the [virtual] warp bundle = cross-sectional area S (mm.sup.2) of said [virtual] warp bundle ÷
woven belt width (mm) ______________________________________wherein the cross-sectional area S of said warp bundle is determined assuming a cross-sectional shape thereof as circular, a diameter thereof in mm being determined by the following formula;
