Cad Software Based Design of Yarn Guide Profile

Abstract

Pragnya S. Kanade, S. S. Bhattacharya and Akash Pandey

The traversing mechanism on a winding machine causes the yarn guide and hence the yarn to reciprocate. This work is an attempt to eliminate the too and fro motion of the yarn guide wherein the guide profile ensures proper transfer of yarn with the desired pattern and pitch. The change in yarn direction after completing one axial traverse poses the most challenging aspect in designing an efficient guide profile. With idealizing assumption of the yarn behaving as a thin wire under the taut condition between three support points at the top ring, profile point on the guide and the bobbin, the ideal profile for consistent guidance of the yarn has been developed.
