Definitions

  • ABSTRACT This invention relates to a device for the pneumatic squeezing of a continuously moving thread.
  • the device comprises a substantially cone-shaped squeezing chamber traversed axially by the thread and fed tangentially with a squeezing fluid. It is more especially intended for the squeezing of a textile thread.
  • the present invention 'relates to a device forthe squeezing of a continuously moving thread by means of compressed air.
  • the device is 'more especiallyadapted to the squeezing of textile threads.
  • textile thread any flexible product whose cross-section is of small dimensions in relation to its length whether it is natural or synthetic and made up of continuous or discontinuous fibres.
  • the present invention has as its aim to realize a device for the pneumatic squeezing of a textile thread which is efficient at a low operating pressure and which does not harm the thread.
  • the device comprises a substantially cone-shaped squeezing chamber traversed axially by the thread which enters the chamber at the end having the smallest cross-section and leaves the chamber at the end having the largest crosssection.
  • a pipe opening out tangentially to the inner wall of the chamber into the part of the chamber having the largest cross-section feeds the chamber with compressed air to which is imparted a helical motion, similar to a cyclone.
  • the inlet orifice through which the thread enters the chamber is in convergent-divergent form.
  • the outlet orifice is preferably constituted by a tube which extends axially in one part of the chamber and surrounds the thread, serving as a guide and offering protection.
  • the tangential feed is effected in such a way as to give the air circulating in the chamber an either S or Z direction of rotation.
  • the attached drawing shows schematically the pneumatic squeezing device in accordance with the invention.
  • the thread 1 is made to traverse axially this squeezing device in the direction of the arrow.
  • the device comprises mainly a chamber 2 provided with an inlet orifice 3 and an outlet orifice 4 for the passage of the thread, these orifices being aligned axially.
  • This chamher 2 is substantially cone-shaped.
  • the inlet orifice 3 is placed in the part of the chamber 2 having the smallest cross-section and has been given convergent-divergent shape, the neck of which has a diameter close to that of the thread being treated.
  • the inner diameter of this tube is close to that of the thread being treated and its function will be specified further
  • This charnber 2 comprises a pipe 6 opening out into the "part of the chamber having the largest crosssec ti onfwhich is the exit area of the thread.
  • This pipe is substantially tangent to the inner wall of the chamber 2.
  • ltslaxis is preferably perpendicular to the axis of the chamber.
  • This pipe is connected to a compressed air feed-device which is not shown here.
  • a recovery chamber 7 which may be of any shape and which comprises a pipe 8 for the evacuation of the product removed from the thread 1 by squeezing, which product may eventually be recycled.
  • the chmber 2 is fed with compressed air by the pipe 6. Any other fluid being able to ensure an efficient squeezing or even a treatment may be used. Owing to the cone-shaped chamber 2 and the tangential feed, the air is set into a whirling movement and escapes through orifice 3. The direction of rotation will be either S or Z, depending on the position of the pipe 6. As happens in a cyclone, part of this air tends to circulate backwards along the axis of the chamber and to escape through the orifice 4. This effect is partially limited by the presence of the tube 5 and by its small inner diameter determined by that of the thread being treated.
  • the tube 5 plays in fact a very important part. As outlined above, it limits the quantity of air escaping through the orifice 4 contributing thereby to a good squeezing at 3. Moreover, it ensures the guidance of the thread in the chamber 2 by causing the thread to remain in the axis of the whirling motion, it prevents it from rotating and from coming into contact with the inner surface of the chamber 2, which would obviously be harmful. Finally, it protects the thread against the action of the compressed air at the moment when it penetrates into the chamber 2 and is not yet in rotation.
  • this tube 5 depends on the pressure of the compressed air, on the running speed of the thread, on the desired squeezing rate. on the shape of the squeezing chamber and on the diameters of the entrance and exit of the air.
  • a device for the pneumatic squeezing ofa continuously moving thread comprising a squeezing chamber provided with inlet orifice and an outlet orifice for the thread, these orifices being aligned in the axis of said chamber. and a pipe for feeding the chamber with squeezing fluid, characterised in that the chamber is substantially cone-shaped the inlet orifice for the thread is placed at the end of the chamber having the smallest cross-section the outlet orifice for the thread is placed at the end of the chamber having the largest cross-section the squeezing fluid feed pipe communicates with that part of the chamber having the largest cross section, tangentally to the inner wall of the chamher.
