Analysis of Working Characteristics of Coreless Disc Tensioner in Winding Machine

摘要

The paper introduces the structure and working principle of coreless disc tensioner, using Euler tension formula to calculate the output tension, analyzing the yarn diameterin ideal and actual situations and getting amplification characteristics of the disc tensioner against tension fluctuation. It is found that the tension disc will not expand the tension fluctuation amplitude in ideal condition, and its own performance has certain compensation for the tension fluctuation, which provides a the oretical basis for the design of the coreless disc tensioner and its wide application.
