ABSTRACT:
A method and apparatus for making a novelty yarn, having relatively short varying length and varying size auxiliary strands randomly distributed therealong, on a spinning frame provided with a series of spaced pairs of rotatable drafting elements defining a drafting zone, which drafting elements include a pair of delivery rolls. The novelty yarn is formed by advancing at least one strand of staple fibers into and through the drafting zone while continuously forming therefrom a ground strand of drafted staple fibers emerging from the delivery rolls. An auxiliary strand of staple fibers is fed through the nip of a pair of auxiliary feed rolls and to the nip of the delivery rolls while the auxiliary feed rolls are being rotated at a slower effective speed than the effective speed of the delivery rolls so as to effect a random parting of the auxiliary strand and thereby form relatively short varying length auxiliary strands randomly distributed along the ground strand. The ground strand and the randomly distributed auxiliary strand are twisted as they emerge from the delivery rolls to arrange the auxiliary strands spirally around the ground strand to form a novelty yarn therefrom. While the novelty yarn is being formed, the auxiliary strand is shielded from contacting the rotatable drafting elements immediately behind the delivery rolls during the travel of the auxiliary strand to the delivery rolls to thereby prevent the auxiliary strand from being misdirected rearwardly away from the delivery rolls.
