Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing texturing machines face challenges in maintaining a favorable thread path within the texturing zone and achieving efficient operation of processing units, often requiring complex arrangements and significant machine height due to deflections and the need for additional thread guides.
Innovation Solution
The cooling device is positioned between the texturing unit and heating device in a straight path, with heating devices arranged parallel and inclined, allowing for a compact machine design and minimizing thread deflections, and a curved cooling rail ensures smooth transitions between processing units, maintaining a consistent thread path without additional guides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the heating device and cooling device are arranged within the texturing zone at an angle to a cross-sectional plane of the machine, then relatively long texturing zones can be realized with a low overall height of the machine, but the thread has to pass through a number of deflections within the texturing zone which are critical for obtaining an undisturbed return of the false twist
Solution Approach 1:
The heating device is arranged at an angle to the cross-sectional plane of the machine, extending in the machine longitudinal direction. This dimensional arrangement allows the texturing zone to be lengthened without increasing machine height, while the thread path remains substantially straight by aligning the heating device's thread inlet and outlet in the same cross-sectional plane
Solution Approach 2:
The texturing zone is segmented into distinct functional sections: a heating section with the heating device, a cooling section with the cooling device, and a texturing section with the false twist texturing unit. This segmentation allows each component to be optimized independently while maintaining an overall straight thread path
2Length of stationary object
If the heating device and cooling device are arranged together with the delivery mechanisms in one machine cross-sectional plane, then long pronounced texturing zones can be realized, but the machine requires a large room height and complicates the operability of the process units
Solution Approach 1:
Instead of arranging all components in a single cross-sectional plane requiring large room height, the heating device is arranged at an angle in the machine longitudinal direction. This uses the longitudinal dimension to achieve length while maintaining a compact cross-sectional footprint and ground-level operability
Solution Approach 2:
Rather than arranging components vertically in a superstructure requiring large room height, the invention arranges the heating device inclined in the longitudinal direction, inverting the traditional vertical arrangement approach and achieving compactness while maintaining texturing zone length
3Manufacturing precision
If additional thread guides are added to the texturing zone to maintain straight thread path, then thread treatment uniformity is improved, but the device complexity and number of components increases
Solution Approach 1:
The heating device serves multiple functions: it provides thermal energy for texturing, defines the texturing zone boundaries, and guides the thread through its inlet and outlet positioned in the same cross-sectional plane. This eliminates the need for separate thread guides while maintaining straight thread path and treatment uniformity

AI summary
The invention relates to a texturing machine, comprising a plurality of processing stations arranged adjacent to each other for drawing off a plurality of threads from supply spools, for stretching and texturing the threads, and for winding the threads into spools. Each of the processing stations has a texturing zone, which is formed between two delivery units and which has a texturing unit and a heating device and a cooling device, wherein the heating device is arranged at an angle to a machine cross-sectional plane. In order to obtain a favorable thread coarse together with operability, the cooling device is formed between the texturing unit and the heating device within one of the processing stations in such a way that the thread can be guided having a straight thread course between the heating device and a thread inlet of the cooling device and between the texturing unit and a thread outlet of the cooling device. Thus, the thread effects required for stretching and texturing can be undistorted.
