Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spinning and twisting machines generate high tension in yarns, leading to potential damage and reduced productivity due to limited rotation speed, especially when handling delicate yarns.
Innovation Solution
Implementing a method that uses multiple hyperboloid structures to create multiple stretches of balloon, increasing the height and diameter of the balloon stretches, thereby reducing yarn tension and allowing higher rotation speeds and productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotation speed is increased to improve productivity, then the yarn tension increases causing damage and breakages
Solution Approach 1:
The balloon is divided into multiple stretches (first stretch, second stretch, etc.) separated by tension means. This segmentation allows the yarn to be supported at multiple points, distributing the tension and reducing peak tension values even at high rotation speeds, thereby preventing yarn damage while maintaining productivity
Solution Approach 2:
Tension means are introduced as intermediary elements between the yarn feeding means and yarn picking means. These intermediaries support the yarn at multiple points along its path, reducing the overall tension in the yarn while allowing high rotation speeds to be maintained for improved productivity
2Area of stationary object
If the balloon diameter is limited to reduce machine size, then the rotation speed must be reduced lowering productivity
Solution Approach 1:
The invention transitions from a single-plane balloon to a three-dimensional structure with multiple stretches arranged vertically and horizontally. By utilizing multiple dimensions (first stretch, second stretch, etc.), the system achieves high rotation speeds without requiring excessive horizontal space, thus maintaining compact machine footprint while improving productivity
3Strength
If multiple stretches of balloon are created to reduce yarn tension, then the machine complexity increases
Solution Approach 1:
Each tension means serves multiple functions: it supports the yarn, reduces tension, and helps define the balloon geometry. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in machine complexity while achieving multiple stretches of balloon for improved yarn integrity

PROCESS FOR SPINNING AND/OR TWISTING YARNS, MACHINE FOR SPINNING AND/OR TWISTING YARNS AND METHOD TO TRANSFORM A MACHINE FOR SPINNING AND/OR TWISTING YARNS. A feature of the invention should be a process of yarn spinning and/or twisting, in which a yarn runs between a yarn feeding means (1) towards a yarn picking means, the said yarn picking means being connected to driving means to rotate the yarn picking means at a predetermined speed, in which a stretch of balloon is generated in a point located between the feeding means (1) and the picking means by the presence of twisting means. The fact that the value of the rotation speed of the yarn twisting means is such that it generates a helical path with oscillating spiral diameters along the distance existing between the yarn feeding means (1) and the yarn picking means, so that the path of the yarn, by the operation of the twisting means, creates a body of revolution from a diameter generating a balloon that has at least a hyperboloid structure (E) forming at least two stretches of balloons (B) consecutive to each other. A second feature of the invention should be the yarn spinning and/or twisting machine that includes a yarn feeding means (1) to supply at least a yarn (3), a yarn picking means for the yarn handled (3), twisting means arranged between the yarn feeding means and the yarn picking means that generate diameter generating (DB) a stretch of balloon of the yarn (3) in an area generating a stretch of balloon (B) with a generating diameter (DB), driving means (4) connected to yarn feeding and/or picking, and does not include elements limiting the balloon and is characterized in that the distance (LB) existing between the guiding means and the area generating a stretch of balloon is at least two times the diameter generating the balloon (DB), so that at least two stretches of balloon (B) are generated between the guiding means (8) and the area generating a stretch of balloon. Last, another feature of the invention should be the method to transform a yarn spinning and/or twisting machine including a set in which the height of the stretch of balloon (LB) is increased so that, by operating the twisting means, a body of revolution is created from a diameter generating a balloon that has at least a hyperboloid structure (E) that forms at least two stretches of balloons (B) consecutive to each other.
