Abstract
The invention concerns an improved yarn package, process and apparatus. The improved package has particular utility in automated processes for making melt spun yarn. Broadly, the invention comprises (a) a cross wound package of melt spun flat filament yarn that is characterized by the yarn's outer end being pile wound in a compact bunch on the cross wound package's surface, the yarn end comprising at least twenty pile turns, the pile turns comprising upstream pile turns and downstream pile turns, and wherein the upstream pile turns partly underlap the downstream pile turns; and (b and c) modifications to conventional process and conventional apparatus for winding yarns, in order to make such packages, particularly at speeds greater than 3000 mpm.
