Abstract
An air nozzle for spinning yarn is positioned adjacent a pair of drafting rollers. The space between a cap covering the nozzle and the nozzle itself forms a tank for the air to be jetted through the nozzle. A tapered throttle located behind the nozzle reduces resistance to air exiting from the jetting ports.
