A friction spinning apparatus comprises an opening roller system for feeding fibres in a feed duct to the throat formed between the adjacent peripheral surfaces of two parallel drums rotating in the same direction. Yarn formed at the throat, by frictional contact between the fed fibres and the surfaces, is withdrawn along the throat. The fibre feed duct is arranged to feed the fibres in an airstream having a direction inclined to the yarn axis and providing a component of fiber movement opposite to the direction of yarn withdrawal. A suction opening in the duct wall facing away from the drums causes an additional airstream across the duct parallel to the yarn axis to turn the fibres from the direction of inclination to a direction more nearly parallel to the yarn axis as they approach the throat. One of the drums is perforated for suction through its surface, the other is imperforate and formed with a resilient surface of a rubber material.
