ABSTRACT:
A friction spinning apparatus includes two drums being driven in the same direction and defining a wedge-shaped gap therebetween with a spinning region. A suction device is disposed in at least one of the drums and directed against the wedge-shaped gap. A yarn draw-off apparatus draws off yarn produced in the wedge-shaped gap. A fiber supply device is provided with a fiber guide channel. The fiber guide channel has one side with a slit-like fiber dispersion opening formed therein and disposed in the wedge-shaped gap and another side facing away from the fiber dispersion opening. A variable ventilation opening is formed in the other side of the fiber guide channel for varying fiber mass distribution in the spinning region.
