[0087] figure 1 The nozzle 1 according to the present invention has a yarn passage 2 and an air hole 3 in a cross section. The yarn passage 2 is formed by a mutually coupled plates 8, 9. The air hole 3 has a longitudinal axis A and incorporated into the yarn passage 2 in the inlet 4. In the yarn passage 2, the filament 10 (not shown, for example, see image 3 ) Is delivered along the conveying direction B. The inlet 4 is substantially located at the center of the nozzle 1 along the conveying direction B and is arranged at an angle of about 85 ° with respect to the conveying direction B. Tangled air 13 (not shown, see Figure 5 The yarn passage 2 is introduced through the air hole 3 in the direction of the longitudinal axis A. Tangled air impact the baffle surface 5 in a vertical manner. Due to the impact of the tangled air 13 on the baffle surface 5, two local flow turbulence 13 ', 13 "(not shown, see Figure 5 . The vertical impact of the tangled air 13 results in a configuration i...
