Abstract
Yarn is unwound from a reel by means of unwinding rollers. Simultaneously the yarn is untwisted partially to free constituent fibers by means of a rotating arm guiding the yarn through an eye. Nip rollers prevent slack in the untwisted yarn. Drafting rollers draft the untwisted yarn to break bonding among the fibers. A pair of endless belts moving in opposing relation hold the drafted fibers together in a bundle. The fibers are sucked from the bundle via a conduit into a foraminous container from which the fibers can individually be reclaimed for testing.
