[origin: EP2730685A1] The yarn formation element (1) has a spinning tip (4) that is provided with an inlet opening (6) surrounded with an outermost surface (5). The air flow is enabled in the inlet opening for forming the yarn (2). An insert (7) is inserted into the inlet opening and is adjoined with an exhaust duct (8). Several air outlet apertures (9) are branched laterally from the exhaust duct so that an air flow is partially brought into the exhaust duct against the spinning direction (S) over the air outlet apertures and is escaped partially over the inlet opening. An independent claim is included for spinning nozzle of air spinning machine.
