ABSTRACT:
A friction spinning apparatus comprises two rollers in closely spaced parallel arrangement which define between them a yarn formation zone at an elongate gap along the rollers and a feed duct which extends into the gap so as to feed fibres directly into the gap in such a manner that they can fall directly onto the yarn. The feed duct is biassed slightly toward the roller which turns into the gap so as to increase the proportion of fibres joining the yarn at the junction with that roller.
