AI Technical Summary

Technical Problem

Existing false twisting machines rely on manual splicing of yarn ends, leading to variable knot quality that affects yarn properties and untwist tension, with no means to accurately determine the untwist tension of false-twisted knots, impacting the quality evaluation of winding packages.

Method used

A false twisting machine equipped with a tension detection device, switch detection device, and information processing device to calculate and store untwisting tension data, allowing for the determination of untwist tension and quality evaluation of knots.

Benefits of technology

Enables precise determination of untwist tension and quality evaluation of false-twisted knots, ensuring consistent yarn quality by distinguishing between normal and abnormal tension data.

Abstract

To provide a false twisting machine capable of specifying untwisting tension of a false twisted node.SOLUTION: A false twisting machine 1 includes: a tension detection device 20 for detecting untwisting tension of a traveling yarn Y between yarn feeding packages P1 and P2 and a take-up package P3; a switching detection device 30 for detecting that the yarn feeding package supplying the yarn Y has switched from one yarn feeding package P1 to another yarn feeding package P2; and an information processing device 40 that calculates, based on a detection result of the switching detection device 30, the movement time zone in which a node C between a yarn end Y1 of one yarn feeding package P1 and a yarn end Y2 of the other yarn feeding package P2 is predicted to move the tension detection device 20, and that extracts and stores a tension data group corresponding to the movement time zone from a detection result of the tension detection device 20.SELECTED DRAWING: Figure 1
