Air-jet spinning apparatus |
摘要 |
An air spinning device has a nozzle body and a hollow spindle with a spindle tip and a longitudinal axis, wherein the spindle tip protrudes into the nozzle body. An outlet channel having a ring-shaped cross-sectional area is formed between an outside surface of the spindle tip and an inside surface of the nozzle body. The gap width at a certain location of the outlet channel normal to the longitudinal axis of the spindle is constant over the circumference of the spindle. The outside surface of the spindle tip and/or the inside surface of the nozzle body is/are shaped in such a way that at least two constrictions are formed in the outlet channel in its course in the direction of the longitudinal axis of the spindle, wherein the outlet channel has a ring-shaped cross-sectional area at each of these constrictions smaller than the ring-shaped cross-sectional area of the outlet channel upstream and downstream from each of these constrictions.
