Abstract
To improve integration of fibers into a yarn end and thereby improve yarn quality, fibers are directed to a feeding nip defined on an opposite side of a pair of friction rollers forming a spinning nip. The fibers are directed out of the feeding nip, passed between the friction rollers, and forwarded into the spinning nip. One of the friction rollers may constitute a conveying roller which exerts greater force upon the fibers than the other roller to securely convey fibers through a gap between the rollers and into the spinning nip.
