Abstract
A layered yarn package is formed of continuous filament yarn wads wherein the yarn alternates between compacted and extended lengths by axially compacting the yarn into a length, segmenting the length into alternating extended and compacted lengths, then arranging the compacted lengths in a common axial direction one next to the other to form a layer. The segmenting is accomplished by jetting pressurized fluid onto the continuous filament yarn wads in a programmed manner.
