ABSTRACT:
A process and apparatus for producing thick and thin filaments wherein the deniers of the thick portions of the filaments are randomized by passing an undrawn nylon feed yarn from a supply package under tension through the nip in a feed/cott roll combination, the cott roll having at least one peripheral slot periodically opening the nip. The yarn is forwarded from this nip by a draw roll assembly operated at a peripheral velocity of 3-5X that of the feed roll to fully draw the drawn portions. A snubbing device is used upstream of the feed/cott roll assembly to provide a yarn tension immediately upstream of the nip.
