Industrial Fabric Seam Element for Flush, Strong Seaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for seaming woven industrial fabrics are time-consuming and face challenges in ensuring sufficient seam strength while maintaining compatibility with the fabric's characteristics, often resulting in discontinuities at the seam area.
Innovation Solution
The use of seaming elements with elongate bodies and channelled protrusions that are securely attached to the fabric's edges, allowing for alignment and engagement to form a secure seam, either through direct connection or with a pintle, minimizing thickness differences and ensuring compatibility with the fabric's overall structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional loop creation methods are used to seam fabric edges, then seam strength can be achieved, but the process becomes time-consuming and complex
Solution Approach 1:
The seaming system is divided into separate components: seaming elements with engagement features that attach to fabric edges, and a separate joining mechanism. This segmentation allows for faster attachment compared to creating loops in every yarn, while maintaining seam strength through the distributed engagement features along the seaming elements.
Solution Approach 2:
Seaming elements are pre-equipped with engagement features (protrusions, channels, or hooks) before attachment to the fabric. This preliminary preparation eliminates the need for time-consuming loop creation during the seaming process, as the engagement features are already in place to receive the joining mechanism.
2Strength
If yarn ends are woven back individually into the fabric to create secure loops, then seam strength is improved, but the fabric characteristics and thickness uniformity deteriorate
Solution Approach 1:
The seaming element is inserted between the fabric layers, extracting the seaming function from the fabric structure itself. This allows the fabric to maintain its original thickness and characteristics, while the seaming element provides the necessary strength without requiring yarns to be woven back individually, which would create thickness variations.
Solution Approach 2:
The seaming element is designed with varying engagement features at different locations - protrusions at one end for attachment to one fabric edge, channels or receiving features at the other end for joining with the opposing seaming element. This local differentiation provides secure attachment throughout the seam length while maintaining overall fabric uniformity.
3Productivity
If seaming elements are attached to fabric edges, then seaming speed is improved, but the complexity of the seaming device increases
Solution Approach 1:
The seaming element is designed as a multi-functional component that simultaneously provides attachment to the fabric edge, structural support for the seam, and the engagement features for joining with the opposing seaming element. This universality reduces the need for separate components, thereby managing device complexity while maintaining high seaming speed.
Solution Approach 2:
The seaming element incorporates nested engagement features within its structure - protrusions that extend from the body, channels that are formed within the element, or hooks that are integrated into the design. This nesting allows multiple functions to be contained within a single element, reducing overall device complexity while enabling fast seaming.

AI summary
A seaming element for seaming industrial textiles for filtration or other uses, an industrial textile with seaming elements, and a method of seaming such textiles. The seaming element is secured to a first seamable end or edge of the fabric, and includes at least one extension member, which can be a channelled protrusion, and which is engageable with a corresponding at least one extension member of a corresponding seaming element secured to the second seamable end or edge. The seaming elements are configured and dimensioned so that when the extensions or protrusions of the two seaming elements are aligned together and engaged, in some embodiments being secured by a pintle, they have a thickness which is compatible with the caliper of the finished fabric, to form a secure seam while avoiding or minimizing any discontinuity or irregularity in the finished fabric.
