ABSTRACT:
An arrangement for manufacturing a spun thread from a staple fiber mass includes a feed channel having an outlet opening for feeding the fiber mass, and a yarn withdrawal channel having an inlet opening. In order to generate a rotating current around the entry opening of the yarn withdrawal channel, a vortex chamber is provided with compressed air nozzles. An air evacuation duct surrounds, essentially ring-like, a stationary, spindle-shaped component which forms the yarn withdrawal channel. The feed channel extends in a meandering manner and includes fiber guiding surfaces, which are designed in the form of deflecting edges, between which the staple fiber mass is without support.
