Abstract
A friction spinning unit includes a pair of cylindrical friction spinning rollers of which one has an air nozzle mounted adjacent to its periphery and able to discharge a current of air along the surface of that roller so as to move any unwanted fibres which may be on the surface of said roller. The air jet from the nozzle may provide a pneumatic barrier to hold fibres away from an annular passage between a surrounding shroud and the outer foraminous sleeve of the foraminous roller, and/or the air jet may be used to clear a fibrous slub from the spinning nip in the event of such a slub forming after a yarn break.
