In the case of an arrangement for pneumatic false-twist spinning, it is provided that a sliver is divided in the area of the delivery roller pair of a drafting unit, is divided into two partial slivers. Edge fibers are spread away during and after the division. The divided slivers are then jointly or separately pneumatically false-twisted and are wound up as an individual yarn, as two separate yarns or as a double yarn.
