Airjet Spinning Arrangement

Abstract

An airjet spinning arrangement includes a fiber feed channel, which runs into a vortex chamber, and a fiber withdrawal channel, which exits out of the vortex chamber. The fiber withdrawal channel is arranged in a spindle-shaped component, which can be moved away from the fiber feed channel by a moving device. In order to clean the area of the entry opening of the thread withdrawal channel, a cleaning channel is provided, which is directed against the spindle-shaped component and is connected to a pressurized air source. The cleaning channel runs into a ring channel, which surrounds the spindle-shaped component. A first exit opening of this ring channel is designed so that it forms a ring opening surrounding the spindle-shaped component and is directed against the spindle shaped component when the spindle-shaped component is moved away from the fiber feed channel. A second exit opening of the ring channel runs via an intermediary channel into the thread withdrawal channel and is directed against the entry opening of the thread withdrawal channel. Thus, the area of the entry opening maybe cleaned from the inside and the outside in the case of maintenance.

       6 . An airjet spinning arrangement, comprising:
 a fiber feed channel which runs into a vortex chamber;   a fiber withdrawal channel exiting out of the vortex chamber and having an entry opening, said fiber withdrawal channel being arranged in a spindle-shaped component;   a moving device for moving the spindle-shaped component away from the fiber feed channel; and   a cleaning channel having an exit opening directed against the spindle-shaped component and being connectable to a pressurized air source, wherein the cleaning channel runs into a ring channel which surrounds the spindle-shaped component, from which a first exit opening that occurs when the spindle-shaped component is moved away from the fiber feed channel is designed as a ring opening surrounding the spindle-shaped component and being directed against the fiber feed channel; and   wherein from the ring channel a second exit opening runs via an intermediary channel into the thread withdrawal channel, the second exit opening being directed against the entry opening of the thread withdrawal channel.   
   
   
       7 . The airjet spinning arrangement according to  claim 6 , wherein the first exit opening is closed when the spindle-shaped component is not moved away from the fiber feed channel. 
   
   
       8 . The airjet spinning arrangement according to  claim 7 , wherein the spindle-shaped component comprises an area having a smaller outer diameter, which opens the ring opening when the spindle-shaped component is moved away from the fiber feed channel, and also comprises an area having a larger outer diameter, which closes the ring opening with a sealing gap when the spindle-shaped component is not moved away from the fiber feed channel. 
   
   
       9 . A component of an airjet spinning arrangement in which a fiber feed channel runs into a vortex chamber, comprising:
 a spindle-shaped component through which extends a fiber withdrawal channel, an entry opening of the fiber withdrawal channel being located at one end of the spindle-shaped component which extends into the vortex chamber when in use; and   a cleaning channel arranged to have an entry opening on an exterior of the spindle-shaped component and an exit opening into the fiber withdrawal channel extending through the spindle-shaped component, whereby pressurized air may be directed toward the entry opening of the fiber feed channel from within the spindle-shaped component.   
   
   
       10 . The component according to  claim 9 , wherein the spindle-shaped component comprises an area having a smaller outer diameter operatively configured to open a ring opening surrounding the spindle-shaped component when the spindle-shaped component is moved away from the fiber feed channel, the spindle-shaped component further comprising an area having a larger outer diameter operatively configured to close, via a sealing gap, the ring opening when the spindle-shaped component is in an operational position of the airjet spinning arrangement.
