A friction spinning apparatus comprises two rollers 1,2 in closely spaced parallel arrangement which define between them a yarn formation zone at an elongate gap along the rollers and a feed duct 41' 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 419. The feed duct comprises two parts 415, 416, one 415 of which includes a planar portion defining a side wall of the fibre feed passage along the duct and the other 416 of which is a complex part defining the opposite side wall as well as end walls which in the fitted and assembled fibre feed duct extend between the opposite side walls.
