ABSTRACT:
A friction spinning apparatus and process use at least one perforated roller enclosing a suction sleeve having the static pressure applied along its suction slot changing between a tip end of the fibre bundle forming the yarn and a downstream location of the fibre bundle whereby the tip end is subjected to a weaker suction effect holding it against the surface than is the stronger downstream part of the fibre bundle.
