Abstract
A device for producing spun yarn by means of an airflow acting in the area between a sliver guide and a spindle (13) on fibers of a non-twisted sliver (10) drafted and delivered by a drafting arrangement in order to twist the fibers. Thereafter, the sliver (10) is passed through the spindle (13). Outside of an imaginary center line (9) of the traveling sliver (10), the sliver guide is arranged such that the fibers are passed along the inward lying surface of the sliver guide. The sliver guide comprises fiber guide elements (16) spaced apart from each other, which permit the free passage of a core fiber bundle. An improved spinning process, along with high productivity and increased yarn strength is possible by means of the device of the invention. The spinning device can be manufactured and operated cost-effectively.
