  • the beam width of the exiting from the annular gap 34 Transportgasstroms depending on the blower output and article range of textile products, are adjusted by axial displacement of the outer nozzle molding 33 usually as a single setting. Since the yarn strand speed depends on the transport gas flow reaching the goods train, changing operating conditions which depend on the respective gas state within the vessel 1 are to be considered on the basis of the characteristic curve of the blower unit 15.
  • actuators acting on the connecting piece 50
  • axial actuators of Fleottenverteilerrings 49 act.
  • the actuators may be controlled by the control unit 65 (FIG. FIG. 9 ).

  • a mounted on the ring plate 24 Verstellspindel 89 is coupled via a pivotally mounted at 87 two-armed lever 88, which allows the conical ring plate 85 to be adjusted axially.
  • the jet nozzles 51 are each attached via a bush 90, such that upon axial adjustment of the ring disk 85, a displacement of the bushing 90 on the threaded connection piece of the respective jet nozzle 51 takes place.
  • the available beam angle range for the jet nozzles 51 is in the selected embodiment for the steel angle without angular deflection 45 ° and can this purpose in an angular range of max. 30 ° can be adjusted according to a beam angle to the transport nozzle axis 29 ° from 75 ° to 15 °.
  • FIG. 12 shows the spray areas of the individual, evenly distributed around the product strand 250 arranged jet nozzles 51 again in a schematic representation. From this representation, it can be seen that the spray areas in the edge zones overlap and total completely enclose the goods strand 250 on all sides.
  • the jet nozzles 47, 51 assigned to the two sections I and III are shielded from the transport gas flow by the inlet nozzle molding 28 and the outer nozzle molding 33, respectively.
  • These shields can have bypass openings in at least one of the two sections I, III, through which gaseous transport medium for flushing the jet nozzles 47 or 51 can flow.
  • Such a bypass opening is, for example, indicated at 92 and 93, respectively.
  • the jet angles which include the jet nozzles 47, 51 in the first and second sections I and III, respectively, with the transport nozzle axis 29 may be the same or different from each other.
