Fabric Strip Assembly to Knitted Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling fabric strips to knitted articles, such as tights, are characterized by complex operations, low productivity, high manufacturing costs, and a large use of manpower, leading to inefficiencies and potential errors in producing uniform and high-quality textile items.
Innovation Solution
A method and apparatus that utilize loading forms and members to position and join fabric strips to knitted articles in an automatic and precise manner, aligning the fabric strip's welt with the article's open border, and using sewing or other joining techniques to create a seamless assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operations are used to prepare and seam the fabric strip onto the knitted article, then flexibility and adaptability are maintained, but productivity is low and manufacturing time is long
Solution Approach 1:
The knitted article and fabric strip are pre-loaded onto loading forms in specific positions before the seaming operation. The loading forms hold the workpieces in predetermined configurations, enabling the automated seaming machine to perform joining operations without manual intervention during the actual seaming process, thus increasing productivity while maintaining precision.
2Manufacturing precision
If manual seaming operations are performed one by one, then quality control is possible, but errors occur and uniformity is difficult to achieve
Solution Approach 1:
Loading forms are introduced as intermediary devices that hold both the knitted article and fabric strip in precise positions. These loading forms act as mediators between the automated seaming machine and the workpieces, ensuring uniform alignment and positioning throughout the seaming process, which guarantees consistent quality and uniformity across all produced items.
3Reliability
If complex manufacturing cycles are used to assemble fabric strips, then joining accuracy can be achieved, but manufacturing costs increase and manpower requirements increase
Solution Approach 1:
The loading forms serve to combine multiple functions into a single device: they hold the workpiece, maintain proper positioning, and facilitate transfer between operations. By merging these functions into one integrated system, the patent achieves reliable joining accuracy while simplifying the overall manufacturing process and reducing the need for multiple separate operations and manpower.

AI summary
A method and related apparatus for assembling a fabric strip to a knitted article. The method includes the steps of loading a knitted article onto a loading form, wrapping at least an end portion of the knitted article so that an open end thereof is accessible, loading a fabric strip onto loading members, and wrapping it thereon so that a first welt is accessible. Additionally, the method includes mutually positioning the loading form and the loading members by aligning the loading form with respect to the loading members, introducing the loading form into an inner space of the loading members so that the fabric strip surrounds outside the end portion of the knitted article, and letting the first welt overlap and match the open border.
