ABSTRACT:
In the case of an arrangement for open-end friction spinning having two friction rollers that are arranged next to one another to form a wedge-shaped yarn forming gap, the frictional effect is reduced in the area of the yarn tip of the forming yarn. As a result, it is avoided that the yarn tip moves through the wedge-shaped gap. It is also ensured that a fiber transport takes place into this area of the wedge-shaped gap where the yarn tip is formed. This fiber transport is caused by an air current generated by an additional suction device, acting as an extension of the yarn tip.
