Abstract
The air nozzle has a continuous yarn channel (3.1) into which terminate laterally an air feed bore (5) and a threading slot (4). The wall of the yarn channel (3.1) contains two cylindrical, for example circular-cylindrical wall sections, namely a baffle wall section (6.1) lying in opposition to the air feed bore (5) and a nozzle wall section (9.1) proximate to the air feed bore (5). The threading slot (4) terminates between the baffle wall section (6.1) and the nozzle wall section (9.1). The tangential plane (T) on the baffle wall section (6.1) at the rim (7) of the orifice of the threading slot (4) passes through the nozzle wall section (9.1). As a result thereof, the portion of the air stream exiting from the air feed bore (5) which is deflected by the baffle wall section (6.1) toward the orifice rim (7) of the threading slot (4), and then leaves the baffle wall section (6.1) in the direction of the tangential plane (T), does not enter into the threading slot (4). Thereby, danger of damage to filaments and filament bundles is reduced since they are not blown into the threading slot (4).
