Abstract
Open end yarn is passed through a drawing zone located between a front roller and a back roller controlled to rotate at different velocities. An air jet nozzle is located between the two rollers and directs a jet of air at the yarn. The drawing improves various characteristics of the yarn, making the processed yarn more suitable for making textile articles.
