Integrated Warp Let-Off Support for Simultaneous Roller Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing warp let-off devices require cumbersome and time-consuming adjustments of easing rollers to improve warp handling, placing a significant burden on operators due to the need for independent position adjustments of multiple supporting structural bodies.
Innovation Solution
A warp let-off device with a pair of single, integrally formed supporting structural bodies that are displaceable in the up-down direction, allowing simultaneous adjustment of both easing rollers while maintaining the interval between them, reducing the operational burden by integrating the first and second supporting sections into a single structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If independent position adjustments are made for multiple supporting structural bodies to improve warp handling, then warp handling quality is improved, but operator burden and adjustment time increase significantly
Solution Approach 1:
The patent combines multiple independent supporting structural bodies (first supporting bracket and second supporting bracket) into a single integrated supporting structural body. This single structure supports both the first easing roller and the second easing roller, allowing simultaneous adjustment of both rollers through one adjustment operation rather than requiring separate adjustments for each roller, thereby reducing operator burden and adjustment time while maintaining warp handling quality
2Adaptability or versatility
If multiple supporting structural bodies are used to support easing rollers, then each roller can be independently positioned, but the device complexity and number of parts increase
Solution Approach 1:
The patent merges multiple supporting structural bodies into a single integrated supporting structural body that includes multiple supporting sections. This single structure maintains the capability to independently position multiple easing rollers through its multiple supporting sections while reducing the overall number of separate parts and simplifying the device structure
Solution Approach 2:
The integrated supporting structural body is divided into multiple supporting sections (first supporting section and second supporting section), each capable of independently supporting an easing roller. This segmentation within the unified structure allows independent positioning of each roller while maintaining structural integration and reducing overall complexity

AI summary
A warp let-off device (20, 20') includes a pair of supporting structural bodies that are disposed apart from each other in a weaving-width direction, each supporting structural body being a single supporting structural body that is mounted on a loom frame so as to be displaceable in an up-down direction with respect to the loom frame. Each supporting structural body includes a first supporting section (52, 52') for supporting a support shaft (31, 34, 34') of one of two easing mechanisms (30a, 30b, 30c) and a second supporting section (70) for supporting the support shaft (31, 34, 34') of the other of the two easing mechanisms (30a, 30b, 30c).
