Abstract
An unusual spun yarn is produced by feeding fibers or a sliver or roving into the interior of a hollow shaft. The shaft includes a perforated portion, and a vacuum is applied at the exterior of the shaft. The shaft is mounted for free rotation about an axis coincident with the direction of movement of the fibers through the shaft, and blades extend radially from the perforated portion of the shaft. When the rotates at high velocity under the influence of the vacuum it produces the unusual spun yarns.
