Title: Pneumatic and static electricity open-end spinning method and apparatus therefor

Abstract: Open-end spinning is accomplished by means of placing similar static electricity charges on an anode member and an inlet anode nose member mounted in a spinning chamber near a feed roller, and by placing a charge opposite said anode member on a cathode member mounted at a downstream portion of the apparatus; introducing an air stream through said inlet anode nose member into said spinning chamber and discharging it through an outlet opening; within said spinning chamber, separating a single fiber from the strand of sliver or roving delivered from feed rollers; charging said single fiber with the same charge of static electricity as the inlet anode nose member, and; hoisting said single fiber into a yarn extending upstream from a twister.
