Air-jet spinning device

Abstract

An airjet spinning arrangement includes a fiber feed channel and a thread withdrawal channel arranged downstream therefrom, which thread withdrawal channel is movable away from the fiber feed channel. An injector channel runs into the thread withdrawal channel, which injector channel is connectable to a compressed air source. The injector channel is arranged in a piston-like component, which piston-like component is movable away from the fiber feed channel by the compressed air fed to the injector channel.

       5 . An airjet spinning arrangement, comprising: 
 a fiber feed channel;    a thread withdrawal channel arranged downstream of the fiber feed channel, the thread withdrawal channel being movable away from the fiber feed channel;    an injector channel which runs into the thread withdrawal channel and which is connectable to a compressed air source;    wherein the thread withdrawal channel is arranged in a piston-like component, which is movable away from the fiber feed channel via compressed air fed to the injector channel.    
   
   
       6 . The airjet spinning arrangement according to  claim 5 , wherein the compressed air acts against a loading spring, which presses the piston-like component into an operational position when the compressed air is cut off.  
   
   
       7 . The airjet spinning arrangement according to  claim 5 , wherein the piston-like component is designed as a valve, which is activatable by the fed in compressed air and which then establishes an effective connection between a conduit for the compressed air and the injector channel.  
   
   
       8 . The airjet spinning arrangement according to  claim 6 , wherein the piston-like component is designed as a valve, which is activatable by the fed in compressed air and which then establishes an effective connection between a conduit for the compressed air and the injector channel.  
   
   
       9 . The airjet spinning arrangement according to  claim 7 , wherein the piston-like component extends through a ring channel, said ring channel being connected to the conduit for compressed air.  
   
   
       10 . The airjet spinning arrangement according to  claim 8 , wherein the piston-like component extends through a ring channel, said ring channel being connected to the conduit for compressed air.  
   
   
       11 . A method of operating an airjet spinning arrangement which utilizes compressed air from a compressed air source to produce spun threads, the airjet spinning arrangement including a fiber feed channel and a thread withdrawal channel arranged downstream of the fiber feed channel, the method comprising the acts of: 
 under normal operation, utilizing the compressed air to produce the spun threads; and    when a piecing process is required, utilizing the compressed air to displace the thread withdrawal channel away from the fiber feed channel, whereby an enlarged space is created to allow for cleaning an area between the fiber feed channel and the thread withdrawal channel.    
   
   
       12 . The method according to  claim 11 , further comprising the act of utilizing the compressed air from the compressed air source to cleaning the area between the fiber feed channel and the thread withdrawal channel.  
   
   
       13 . The method according to  claim 11 , further comprising the act of utilizing the compressed air from the compressed air source to generate a suction current directed against a drafting direction.  
   
   
       14 . The method according to  claim 11 , wherein the thread withdrawal channel is arranged in a piston-like component, the compressed air from the compressed air source displacing the piston-like component against a loading spring when the piecing process is required.
