Spindle-shaped component for an air-jet spinning arrangement with an injection channel

Abstract

A spindle-shaped component for an air jet spinning arrangement is described. The component includes a base body and an attached tip, as well as a yarn withdrawal channel which extends through the base body and the tip, the first part of the yarn withdrawal channel being an entry opening in the tip. The spindle-shaped component also has an injection channel which runs into the yarn withdrawal channel, the injection channel being directed in the direction of the entry opening of the yarn withdrawal channel. The injection channel is formed by a surface area of the base body and a surface area of the tip.

1 . A spindle-shaped component for an air jet spinning arrangement, comprising: 
 a base body;    a tip attached to the base body;    a yarn withdrawal channel extending through the base body and the tip;    an entry opening of the yarn withdrawal channel defined by the tip; and    at least one injection channel of the spindle-shaped component which runs into the yarn withdrawal channel, said at least one injection channel being directed in the direction of the entry opening of the yarn withdrawal channel, wherein the at least one injection channel is formed by a surface area of the base body and by a surface area of the tip.    
   
   
       2 . A spindle-shaped component according to  claim 1 , wherein the at least one injection channel is formed by a cone-shaped surface area of the base body.  
   
   
       3 . A spindle-shaped component according to  claim 1 , wherein the at least one injection channel is formed by a cone-shaped surface area of the tip.  
   
   
       4 . A spindle-shaped component according to  claim 1 , wherein the at least one injection channel is formed by a groove-shaped surface area of the tip.  
   
   
       5 . A spindle-shaped component according to  claim 1 , wherein the at least one injection channel is formed by a groove-shaped surface area of the base body.  
   
   
       6 . A tip for a spindle-shaped component of an air jet spinning arrangement comprising: 
 a yarn withdrawal channel having an entry opening; and    a surface area of the tip forming, when joined together with a second surface area of a base body of the spindle-shaped component, at least one injection channel directed towards the entry opening.    
   
   
       7 . A spindle-shaped component according to  claim 1 , wherein the at least one injection channel is formed by joining together the surface area of the base body with the surface area of the tip.  
   
   
       8 . A spindle-shaped component according to  claim 2 , wherein the at least one injection channel is formed by joining together the surface area of the base body with the surface area of the tip.  
   
   
       9 . An air jet spinning arrangement, comprising: 
 a spindle shaped component defining a yarn withdrawal channel;    an entry opening of the spindle shaped component receiving a yarn into the yarn withdrawal channel;    a base body of the spindle shaped component having a shaped outer surface;    a tip of the spindle shaped component having a shaped inner surface substantially facing the shaped outer surface; and    an injection channel defined between the base body and the tip by the shaped inner surface in cooperation with the shaped outer surface.    
   
   
       10 . The arrangement as claimed in  claim 9 , wherein the injection channel forms an acute angle with the yarn withdrawal channel, towards the entry opening.  
   
   
       11 . The arrangement as claimed in  claim 9 , wherein the inner surface and outer surface are substantially cone-shaped.  
   
   
       12 . The arrangement as claimed in  claim 9 , wherein at least one of the shaped inner surface and outer surface are grooved.  
   
   
       13 . The arrangement as claimed in  claim 12 , wherein at least one of the shaped inner surface and outer surface comprise multiple grooves defining injection channels.
