  • a slotted tube 301 is firmly inserted into the housing bore 136. Its slot 305 coincides with the threading slot 305 of the bore 136.
  • a cylindrical inner body 302 which is rotatable therein and which is in its outer surface has a rectangular groove 303 running axially over its entire length or a rounded groove 304.
  • the inner body 302 is rotated such that groove 303 or 304 and threading slot 305 coincide.
  • the inner body 302 is rotated so that the blow channel 108 meets the groove 303 or 304.
  • the inserted thread 311 is carried along when the inner body 302 rotates.
  • FIG. 3 Another example of a threadable swirl nozzle is shown in the upper example of the right vertical nozzle row.
  • a slotted tube is firmly inserted into the nozzle bore 136. Its slot in turn coincides with the threading slot 305 of the nozzle body 103.
  • An inner tube 307 slotted on a surface line is rotatably inserted in the tube 301. In the position shown, in which the slot of the inner tube 307 covers the threading slot 305 of the nozzle body or tube 305, the thread can be inserted into the inner tube 307.
  • the threading slot 305 is closed and the slot of the inner tube is made to overlap with the blowing channel 306.
  • the two lower examples of the right row of nozzles show a simplified version.
  • the outer tube 301 has been omitted.
  • An inner tube 308 rotatable in the housing bore 136 has a slot 310 which extends over its length and is used for threading, and also has a blow hole 309. Both are offset from each other, for example by about 90 °.
  • the slot 3.10 of the inner tube 308 is in correspondence with the threading slot 305 of the nozzle body 103 13 shows the two situations with one another
  • the nozzle bodies In order to make room for the lateral threading, the nozzle bodies must be moved apart in the area in which the insert nozzles 104 are located.
  • the nozzle body 103 has a lateral widening 312 on its foot part, so that the seal with respect to the air supply bar 101 is also ensured here.
  • the nozzle body shown in Fig.13 z. B. also fastened by means of a dovetail guide and a claw (see, for example, FIG. 6A).
  • the embodiment of the nozzle body according to FIG. 13 has the advantage on the one hand that the threads can be inserted easily. Another advantage also lies in the fact that the vortex nozzles can be separated from the air supply individually by rotating the inner body 302 or inner tube 307, 308 and laid dead. When using such a nozzle body, a particularly simple adaptation of the device to the desired number of threads is therefore possible.
