Abstract

Fibers are carried to a spinning rotor from a fiber-resolving device by a translational fluid medium, such as air, which is first accelerated to orient the fibers. Carrier fluid next is maintained at constant speed and laminar flow to deliver the oriented fibers to a rotating laminar fluid in the region adjacent to the inner wall of the spinning rotor. The acceleration and velocity of the translational fluid is effected by a feed tube having a frustoconical infeed section, tapered toward a cylindrical outfeed section.
