Definitions

  • the constriction can be achieved either by an inclination of the two plates with respect to the interior of the yarn channel or by a vertical course of the two plates with respect to the conveying direction at the inlet opening.
  • inclinations of the plates with respect to the interior of the yarn channel these are preferably uniform, therefore at the same angle over lengths of the slopes.
  • a step is referred to, in which the step height or slope is not perpendicular to the appearance but obliquely, therefore at an angle between 0 ° and 90 °, runs.
  • the constriction at the inlet opening 6 and the extension at the outlet opening 7 cause more air to flow through the outlet opening 7 than via the inlet opening 6.
  • the extension is also designed as an inclined step, which leads away in the conveying direction B of the nozzle plate 9.
  • the baffle is 5 mm long, which is three times longer than a diameter of the air bore 3.
  • Filaments 10 are introduced through the inlet opening 6 in the yarn channel 2 of the nozzle.
  • the filaments 10 are guided largely along the surface of the cover plate 8.
  • the filaments 10 are deflected by an edge 14 at the beginning of the stage 12.
