Abstract
A device for producing spun yarn by means of an airflow acting in a twisting manner on the fibers of an untwisted sliver (,) as the sliver is being conducted into and through a spindle assembly (,). The spindle assembly (,) comprises a spindle head portion (,) which conically tapers toward a spindle inlet opening (,) and is rotatable independently of a spindle core portion (,) through which the yarn is withdrawn. The device suppresses any tendency of the yarn strength to decrease at high, increasing numbers of spindle revolutions.
