  • the object of the invention is to create a texturing nozzle, which is easy to manufacture, easy to assemble and easy maintenance.
  • the more sensitive and faster worn components of the texturing nozzle be easily and quickly exchangeable.
  • Through the Texturing nozzle according to the invention are yarns with the best possible and also be able to produce properties that are as symmetrical as possible. An adjustment of the texturing nozzle to different yarn properties should be carried out as quickly and easily as possible without that the entire texturing nozzle has to be replaced.
  • the more resistant material is advantageously made made of ceramic material. Apart from the poorer workability ceramics has a number of advantages.
  • this is more resistant Material provided by an insert in the base body. This results in easy and quick interchangeability of worn components without the entire texturing nozzle needs to be replaced. On the other hand, the texturing nozzle by changing such inserts easily to changed conditions, how changed yarn properties are adjusted.
  • the more resistant material can also be used be provided by an attachment on the base body.
  • the insert or attachment advantageously includes the Nozzle body of the texturing nozzle.
  • the nozzle body is one component of the texturing nozzle that is particularly susceptible to wear. About that In addition, the yarn properties are through the nozzle body significantly influenced.
  • the suspension can be formed by cuts in the insert his.
  • the Treatment channel in the ventilation part square cross-section has ventilation windows formed by perforated sheets or the like on each side of the treatment channel. Due to the symmetrical Training of the venting part is one if possible symmetrical flow of the texturing air and therefore even Yarn properties achieved. It can also be an undesirable Propagation of the swirl can be prevented effectively.
  • the texturing nozzle according to the invention results in a Flow guidance through which together with the exhaust air zone and the preferably a square version of the treatment channel very compact stopper with very even stopper density as well as a very high and even crimp in the yarn.
  • the top view of the base body 1 is one Texturing nozzle shown. Via a thread inlet channel 2 Thread to be textured introduced into the texturing nozzle.
  • the nozzle body 5 is through supply channels 3 for the gaseous treatment medium educated.
  • the treatment medium preferably air or superheated steam, is over at very high speed the supply channels 3 are injected into the treatment channel 6, so that it at the exit point 4 of the nozzle body 5 for swirl generation comes, which deforms the thread accordingly.
  • the traffic jam 7 of the treatment channel 6 there is at least one venting part 8, through which the injected gas is extracted.
  • the channel cross section in the guide part 9 can be textured yarn be rejuvenated.
  • the cross section of the treatment channel 6 can be round, square or rectangular and varies in its dimensions at least in parts between entry and exit of the filamentary material to be treated.
  • the two base body 1 of the Texturing nozzle can be manual, pneumatic, hydraulic or be electrically closed.
  • the two base bodies 1 are in generally not symmetrical. That is more advantageous Treatment channel 6 only in a base body 1 of the texturing nozzle provided, while the opposite body is executed is.
  • the treatment channel 6 is advantageously at least in some areas with a more resistant material formed as the base body 1, causing a harmful influence of the treatment medium is avoided as much as possible. In this way, a coating or lining made of more resistant Material, for example ceramic his.
  • more resistant Material for example ceramic his.
