Patent ID: 7080502

Claim:
An arrangement for producing a spun yarn from a staple fiber mass, comprising: a feed channel having an outlet opening for feeding the staple fiber mass, a stationary, spindle-shaped component arranged downstream of the outlet opening having a yarn withdrawal channel comprising an inlet opening, a vortex chamber connected to compressed-air nozzles and located between the outlet opening and the inlet opening for generating an eddy current around the inlet opening, an air evacuation duct surrounding, essentially in a ring form, the spindle-shaped component, and fiber guiding surfaces deflecting the staple fiber mass for forming a twist block, wherein the feed channel extends in a meandering manner, wherein the guiding surfaces are designed as deflecting edges, between which the staple fiber mass is without any support, and wherein the last deflecting edge in a direction of motion of the staple fiber mass is arranged eccentrically to the inlet opening of the yarn withdrawal channel.
