<p>A process for winding yarn into a cylindrical-bodied substantially flat-ended package by traverse winding layers of helical coils of yarn on a surface-driven package is improved by not only breaking ribbon formation by the known waveform (minor modulation of inverter output to the traverse motor) from a pre-set point, but also modulating the set point to create a major modulation having a minor modulation superimposed along or within the modulated set point waveform.</p> |
