Industrial Fabric Binding Loop Structure for Seamless Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binding structures for industrial fabrics require skilled techniques and lengthy processes to form an endless type, often resulting in uneven thickness and exposure of fluorine resin yarns, which compromises dirt resistance and binding strength.
Innovation Solution
A binding loop structure where loops are formed by bending warps at both ends, with one end forming a binding loop and the other a loop hole, allowing the core wire to be introduced into the binding loop without protrusion, and using a multi-layered configuration with fluorine resin and PET yarns to maintain anti-dirt properties without structural differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If loops are formed by bending warps at both ends to create binding structure, then the fabric can be mounted on machines and formed into endless type, but the loop forming portion becomes exposed on the surface causing uneven thickness and compromising anti-dirt properties
Solution Approach 1:
The patent applies a multi-layered fabric structure where the binding loops are formed in the lower surface layer while the upper surface layer maintains its continuous structure. This dimensional separation allows the binding function to be achieved without compromising the anti-dirt properties of the upper surface, as the loops are concealed in the lower layer.
Solution Approach 2:
The fabric is divided into multiple layers with different functions: the upper surface layer provides anti-dirt properties while the lower surface layer contains the binding loops. This segmentation allows each layer to perform its specific function without interfering with the other, resolving the contradiction between mounting requirements and surface quality.
2Productivity
If conventional binding methods are used with core wire insertion, then the fabric can be formed into endless type, but the process requires skilled techniques and lengthy processing time
Solution Approach 1:
The patent eliminates the need for core wire insertion by forming binding loops directly in the lower surface layer of the fabric. This extraction of the core wire component simplifies the binding process, reduces processing time, and eliminates the need for skilled operators to perform complex insertion operations.
Solution Approach 2:
The binding loops are formed as integral parts of the fabric structure during the weaving process, allowing the fabric to be self-sufficient for mounting operations. The loops are automatically created in the lower layer without requiring additional processing steps or specialized skills.
3Object-affected harmful factors
If fluorine resin yarns are used for upper surface to prevent dirt, then anti-dirt properties are improved, but the loop forming portion exposes lower surface warp causing structural differences
Solution Approach 1:
The patent uses a multi-layered structure where the fluorine resin yarns are concentrated in the upper surface layer to provide anti-dirt properties, while the lower surface layer contains the binding loops formed by the warp yarns. This vertical separation maintains structural uniformity from the top view while enabling binding functionality in the lower layer.
Solution Approach 2:
Different layers of the fabric are assigned different qualities: the upper surface layer has high anti-dirt properties due to fluorine resin concentration, while the lower surface layer is designed for binding functionality. This local differentiation allows each region to optimize its specific function without compromising overall structural stability.

AI summary
The object of the present invention is to provide an object of the present invention is to provide a binding loop structure of an industrial fabric which is capable of stably and readily carrying out an operation for mounting the industrial fabric with ends on a machine to process it to form an endless type without a need of highly- skilled technique, and thus, shortening a time for such an operation, as compared with a conventional binding operation. The present invention includes a binding structure of an industrial fabric for binding both ends of a fabric with ends to form it into an endless type comprises loops formed by bending a portion or all ends of warp constituting the fabric at both ends and folding it back, the loop at the one end constitutes a binding loop which forms a common hole into which a core wire is introduced upon binding, the loop at the other end portion which is opposed to the binding loop to form a pair with said binding loop upon binding comprises a structure into which said binding loop is fitted and against which said binding loop is locked, and forms a loop hole into which the core wire is not introduced.
