A novel method of yarn traversing suitable even for longer traverse lengths

Abstract

Attempt has been made to develop a novel prototype yarn traversing mechanism for a filter winder to eliminate the use of grooved cam; especially to wind cylindrical packages of longer lengths such as PP/ glass wound filter cartridges. The novel yarn traversing mechanism is found to wind 762 mm (30 inch) long filter cartridges. The traversing mechanism mainly includes three yarn guides mounted on an endless chain passing over six sprockets with an arrangement of relieving yarn from one guide to the other at traverse extremes. Filter cartridges with various traverse ratios are precision wound on this winder with 0.4 hank and 0.6 hank polypropylene yarn. The new traversing mechanism is simple, cost effective and can be adopted to develop a filter winder of any length.
