Filament Web Liquor Application Layout for Upright Thread Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In textile processing, the existing devices for applying sizing agents to threads often result in threads tearing, crossing, or wrapping around rollers, making it difficult for operators to access and handle the threads efficiently, as the horizontal web path blocks access to the liquor application device, requiring operators to lie down and complicating error correction.
Innovation Solution
The web path is redesigned to run above the operator's workspace, allowing the threads to enter the liquor application device from above, with an adjustable working space and input roller arrangement positioned above the trough to ensure accessibility and minimize interference, enabling operators to stand and easily handle threads, while using a trough and nips with rollers to ensure even liquor application and excess removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the web path runs horizontally through the liquor application device, then the threads can be evenly coated with sizing agent, but the operator cannot easily access the threads to fix errors
Solution Approach 1:
The web path is reconfigured from a horizontal arrangement to a vertical arrangement, with the threads running vertically through the liquor application device. This dimensional change allows the operator to access the threads from the front in an upright position, eliminating the need to lie down or reach over blocking components while maintaining effective sizing application.
2Ease of operation
If the threads are fed horizontally through the liquor application device, then the sizing agent can be applied, but the threads block access to the device
Solution Approach 1:
The conventional horizontal feeding arrangement is inverted to a vertical feeding arrangement. The threads are fed vertically from above through the liquor application device, which is accessible from the front. This inversion resolves the blocking issue while maintaining effective sizing application.
3Ease of operation
If the web path is configured to allow operator access, then ease of operation improves, but the thread handling complexity increases
Solution Approach 1:
The input roller arrangement is segmented into multiple rollers positioned at different heights and locations. This segmentation allows the threads to be guided vertically through the liquor application device while providing clear access paths for the operator, distributing the guiding function across multiple discrete roller elements.

AI summary
The present invention relates to a device for applying liquor to a filament web. The device includes an applying component (3) for the filament web (2), a liquor applying device (4) and a path of a width of woolen goods from the applying component (3) to the liquor applying device (4). The device is provided with a comfortable control ability. The path of the width extends on an operation space (17) of an input sector before the liquor applying device (4) so that the operation space is close to the liquor applying device (4) in a horizontal direction.
