Abstract

A friction spinning apparatus, includes oppositely-disposed, rotationally-symmetrical friction elements rotating in the same direction, the friction elements having perforated casings defining a line of closest mutual approach between the casings and two wedge-shaped regions adjacent the line of closest mutual approach, stationery suction devices disposed in the casings, the suction devices having suction apertures directed toward the perforated casings, a fiber feeding device for feeding spinning fibers along a yarn withdrawing direction, and a yarn withdrawing device for withdrawing yarn, each of the casings including a yarn formation zone receiving the spinning fibers at substantially the furthest upstream portion of the casings in the yarn withdrawing direction for continuously forming yarn, a curved transition zone downstream of the yarn formation zone, and a yarn consolidation zone downstream of the transition zone, the yarn consolidation zone being separate from and having a longitudinal axis disposed outside of the yarn formation zone, the yarn consolidation zone being disposed substantially at the furthest downstream portion of the casings.
