Close winding traverse ratio for a particular linear density of yarn builds a compact package with high density. If a close traverse ratio which is suitable for low linear density (finer) yarn is employed for winding a high linear density (coarser) yarn, it would cause over riding of yarn at the end of pattern repeat. Conversely, if a close traverse ratio which is suitable for high linear density yarn is employed for winding a low linear density yarn, it would cause gap between yarns at the end of pattern repeat, leading to a package with less compactness.
2. Package properties can be ‘engineered’ through suitable selection of coil angle and traverse ratios that keep on reducing stepwise. 3. Step-precision wound cylindrical package is built with parallel side faces, which is advantageous for some end-use applications like TFO twisting and package dyeing. 2 Positive aspects of step-precision winding Negative aspects of step-precision winding 1. Cost of winding system becomes high. 2. Winding at a particular diameter starts with a certain traverse.
As shown in Fig. 5) 9 nominal traverse ratio is = = 9. 1 1 It follows from this that numerator of nominal traverse ratio of a close precision wound package is twice number of diamonds counted along a row of diamonds lengthwise and numerator is obtained by counting number of diamonds along a circumferential row. 6 Relation between traverse ratio, coil angle, traverse length and package diameter for a cylindrical package Let ‘T’ be traverse ratio, ‘D’ be package diameter, ‘L’ be traverse length and ‘Ø’ be coil angle.
