Split Webbing Structure With Closed-Edge Woven Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing split webbing weaving methods result in uneven appearances due to oblique thread marks and complex thread control, and direct cutting methods lead to loose finishes with unclosed threads.
Innovation Solution
A split webbing structure with parallel warp threads separated by dividing threads, integrated with a weft thread, and a loom system for precise weaving and cutting, ensuring uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If two side threads are used for diagonal interlacing in traditional weaving method, then the split webbing can be formed, but obvious oblique thread marks appear on the surface resulting in uneven appearance
Solution Approach 1:
The webbing is divided into multiple independent woven units, each containing a closed section and a split section. The dividing threads separate the warp threads into different sets, creating distinct segments that can be controlled independently during weaving, eliminating the need for complex diagonal interlacing of side threads.
Solution Approach 2:
Dividing threads are introduced as intermediary elements between the warp threads. These dividing threads serve as mediators that separate the warp threads into different sets and guide the weft thread to wind around specific warp thread sets in different sections, simplifying the control mechanism compared to traditional diagonal interlacing methods.
2Ease of manufacture
If direct cutting method is used to create split webbing, then the production process is simplified, but the cut sides have unclosed threads causing loose finish and quality problems
Solution Approach 1:
The webbing structure is pre-configured with dividing threads and multiple warp thread sets during the weaving process, so that the split sections are formed with closed threads from the beginning. This preliminary arrangement of threads ensures that when the webbing is cut, the cut sides maintain closed thread structures, preventing loose finishes without requiring post-cutting hemming operations.
3Productivity
If traditional weaving method with two side threads is used, then split webbing can be produced, but the weaving process requires extremely complicated control of weft threads to change from winding all warp threads to winding two sets of warp threads respectively
Solution Approach 1:
The loom is equipped with a dynamic control system that can automatically adjust the weaving pattern based on the position within the woven unit. The control mechanism dynamically switches between winding all warp threads in the closed section and winding only specific warp thread sets in the split section, eliminating the need for manual thread manipulation and simplifying the overall control process.
Solution Approach 2:
The weaving control system incorporates feedback mechanisms that monitor the weaving progress and automatically adjust the weft thread path. When transitioning from closed section to split section, the system receives feedback about the current position and automatically configures the threading pattern, reducing the complexity of thread control compared to traditional methods requiring manual intervention.

AI summary
A split webbing is provided, including: a webbing body woven in one piece by a first and second warp set, a first and a second dividing thread arranged side by side and a weft thread, a closed and a split section provided in sequence along the length of the webbing body, the weft thread being interlaced with the first warp set to form a first sub-webbing, and the weft thread being interlaced with the second warp set to form a second sub-webbing, wherein the inner sides of the first and the second sub-webbing are wound around by the first and the second dividing thread respectively, so as to form a gap between the first and the second sub-webbing, where the weft thread are cut off to separate the first from the second sub-webbing. The split webbing has the advantages of simple weaving control procedure and beautiful product.
