Yarn Tension in Winding Mechanism

Part 3: Stress in Yarn Beams-Experimental Results Discussed

Abstract

Variations in stress in a yarn beam produced by the yarns wound on it were examined and recorded during winding. The yarns used were nylon filament and cotton yarn. The stress in the beam core in axial and circumferential directions was examined with wire strain-gauges attached inside the beam core.
Data on the following subjects have been obtained from experimental results, with the aid of the theoretical results described in Part 2: 1) Yarn pressure on the core and the flanges of the beam 2) The anisotropy of the yarn layer. 3) The general applicability of the theory given in Part 2.
