Abstract
Under influence of positive and negative aerodynamic action imposed on a conic surface, airborne fibers and tufts are compelled to disperse approximately 360.degree. and to enter the rotor of an open-end yarn spinner device, peripherally, thereby minimizing identifiable yarn imperfections and inefficiencies attributive to open-end yarn formation.
