Composite Thread Entangling Unit Adjustment for Carpet Color Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing crimped composite threads with multiple colors lack the flexibility to achieve a broad enough color spectrum and color dominance in carpets, as they are limited by the adjustability and range of color variations using compressed air set-point values and entangling unit positions.
Innovation Solution
The use of actuators to adjust the position and orientation of entangling units relative to the drawing and crimping devices, along with individual or common carriers, allows for precise control of feed and discharge angles, enabling a broader color spectrum and color dominance in the composite thread.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If compressed air set-point values are adjusted to control coloration, then some color variation is achieved, but the flexibility and range of color spectrum are insufficient
Solution Approach 1:
The patent applies the dynamics principle by making the entangling units movable relative to the drawing device and crimping device through actuators. This allows dynamic adjustment of positions and orientations during operation, enabling a broad color spectrum and color dominance in composite threads without requiring complex control systems. The movable entangling units can be repositioned to achieve different color patterns by changing feed and discharge angles.
Solution Approach 2:
The patent changes geometric parameters (position and orientation) of the entangling units rather than relying solely on compressed air set-point values. By adjusting the spatial parameters of entangling units relative to the drawing and crimping devices, the system achieves diverse coloration patterns including color dominance and various color spectra, significantly improving adaptability.
2Adaptability or versatility
If multiple entangling units are arranged in the thread run, then coloration variability is improved, but the range of color spectrum remains insufficient
Solution Approach 1:
Instead of merely arranging multiple entangling units statically in the thread run, the patent makes them dynamically adjustable through actuators. The entangling units can change their positions and orientations during operation, which significantly expands the achievable color spectrum beyond what static arrangements can provide.
Solution Approach 2:
The patent adds the dimension of spatial adjustment by allowing entangling units to move in multiple directions and change orientations. This transforms the system from a one-dimensional linear arrangement to a multi-dimensional configurable structure, enabling diverse color patterns including color dominance by controlling feed and discharge angles.
3Adaptability or versatility
If entangling units are made adjustable, then color spectrum flexibility increases, but device complexity increases
Solution Approach 1:
The patent applies universality by using actuators that can perform multiple functions: adjusting position, changing orientation, controlling feed angles, and managing discharge angles of entangling units. This multi-functionality reduces the need for separate adjustment mechanisms and minimizes overall device complexity while achieving broad color spectrum flexibility.
Solution Approach 2:
The patent changes geometric parameters (position and orientation) of entangling units through actuators to achieve diverse coloration patterns. By adjusting spatial parameters rather than relying on complex control systems, the patent achieves color spectrum flexibility with relatively simple actuator mechanisms.
4Manufacturing precision
If feed and discharge angles are controlled, then color dominance is achieved, but control complexity increases
Solution Approach 1:
The patent uses dynamically adjustable entangling units with actuators that can change positions and orientations during operation. This dynamic adjustment directly controls feed and discharge angles, enabling precise color dominance in composite threads through geometric configuration rather than complex control mechanisms.
Solution Approach 2:
The patent achieves color dominance by changing geometric parameters (position and orientation) of entangling units. The actuators adjust spatial parameters to control feed and discharge angles, providing precise coloration control without requiring complex angle control mechanisms.

Function Achieved in This Case
This approach significantly increases the flexibility in coloration, allowing for a wide range of color patterns and precise control over color dominance in carpets produced from composite threads.
Implementation Method 1
a position and/or orientation of at least one of the entangling units relative to the drawing device, the crimping device and/or a further one of the entangling units can be changed by means of at least one actuator
Implementation Method 2
multiple entangling units are here arranged in the thread run of at least one individual thread in order to produce different colourations of the composite thread. The adjustability and range of variability of the colouration of the composite thread can here be improved by entangling each of the different individual threads with different compressed air set-point values of a compressed air supply
Implementation Method 3
multiple individual threads are extruded, in each case in the form of a plurality of strand-like filaments
Implementation Method 4
a spinning device, a cooling device and a drawing device for producing multiple multifilament individual threads
Implementation Method 5
a spinning device, a cooling device and a drawing device for producing multiple multifilament individual threads
Implementation Method 6
a crimping device for bringing the individual threads together to form the composite thread

AI summary
Techniques produce a crimped composite thread, in which multiple individual threads are extruded in each case in the form of a plurality of strand-shaped filaments, cooled, drawn by means of a drawing device and together crimped by means of a crimping device to form the composite thread. Before the multifilament individual threads are crimped, they are entangled separately in each case by means of an entangling unit of an entangling device. A position and/or orientation of at least one of the entangling units relative to the drawing device, the crimping device and/or a further one of the entangling units is changed during the production of the crimped composite thread.
