<p>A strand of textile-length fibers is drafted and attenuated by the effect of a vacuum applied at the entrance end of an aspirator nozzle, said strand being accelerated through the body of the aspirator and being further accelerated and attenuated by the action of a high velocity air stream concentric with said tube. The resultant high velocity fibrous stream may be decelerated and diffused in a plenum chamber and removed therefrom as a fibrous web.</p> |
