Abstract (en)
[origin: WO2006042738A1] An air jet spinning frame contains a substantially hollow cylindrical turbulence chamber whose circumferential wall forms in the staple sliver entry region a support surface for a circumferential surface of a rotationally symmetrical insert. A plurality of air slots are formed in the circumferential surface of the insert and form closed pressurised air ducts when completed by the support surface. The nozzle-like openings of the pressurised air ducts are arranged in the front side of the insert which faces the turbulence chamber. According to the invention, the air slots are arranged in the form of a multiplex thread.
