Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of flat belt loops, and in particular to a flat belt loop with balanced force at a suture point and a manufacturing method thereof. Background Art
[0002] Sling loops or rope loops are needed for high-altitude work, high-altitude rescue, cargo lifting, fixing and other operations. Sling loops are a kind of narrow fabric, tubular fabric or round rope fabric woven with yarn as raw material, which is then sewn or interlaced and woven to form a closed loop.
[0003] At present, in the actual production process of flat belt loops or rope loops, their closed structure is often simply formed by overlapping the two ends of the rope or belt and sewing them directly. Although they can withstand pulling, they are prone to twisting and deformation when subjected to large forces, and the tensile strength of the seams is much lower than that of the rope or belt body, resulting in poor overall aesthetics of the flat belt loop or rope loop, thick ends that are easy to hook other objects, and a certain waste of the overall mechanical efficiency of the flat belt loop or rope loop.
[0004] Therefore, in order to solve the problems that the above-mentioned flat belt ring has poor overall aesthetics, the end head is thick and easy to hook other objects, and the overall mechanical performance of the flat belt ring is poor, a flat belt ring with balanced force at the seam can be designed to solve the problem of uneven force at the existing seam.
