Definitions

  • the present invention relates to a device for removing the free fibers carried by the reel unwinding ball. It applies in particular, but not exclusively, to such a device used for wrapped spinning, in which a thread axially passes through a hollow rotating spindle which carries a spool of wrapping thread, the latter also being driven in the hollow spindle ( see DE-A-2425901).
  • the object of the invention is to remedy these drawbacks by providing a simple and reliable device which makes it possible to effectively remove the free fibers.
  • the device according to the invention is characterized in that it comprises a fixed closed ring which surrounds the spool at its unwinding end and which has a general plane inclined at an acute angle to the axis of rotation of the spindle.
  • the tilt angle is between 5 ° and 80 °, and is preferably around 30 °.
  • the ring can be circular, with its center located on the axis of the spindle, so that in axial projection it gives an ellipse.
  • the ring is itself elliptical, the ellipse being arranged so that its axial projection is a circle whose center is also located on the axis of the spindle.
  • the ring In the axial direction, the ring can extend, for example, over the first third of the coil, its upper part being situated substantially at the level of the entry of the wire into the hollow spindle.
  • a wrapping installation which comprises, in known manner, input stretching rollers 1 for feeding wire 2 to be wrapped, a hollow rotating spindle 3, a fixed support 4 for the spindle 3, means 5 carried by the spindle 3 to support a coaxial coil 6 of a wrapping wire 7, and delivery rollers 8, at the outlet of the spindle 3, for extracting and delivering the wrapped thread 9.
  • a fixed closed ring 10 which surrounds the spool 6 at a distance, at the unwinding end thereof, and which has a general plane inclined at an acute angle ⁇ relative to the spindle axis of rotation, i.e. the axial direction of travel 2.7 wires in the spindle.
  • this angle of inclination is between 5 and 80 ° and, preferably, it is approximately 30 °.
  • the ring 10 has a convex curved interior surface to ensure good sliding of the wire 7.
  • the ring 10 is constituted by a stainless steel wire.
  • the ring 10 is carried by a vertical blade 11 which, at its lower end, is itself carried by a collar 12 secured to the support 4 of the spindle.
  • the ring 10 is in the form of an ellipse which is determined in such a way that, in axial projection, it appears as a circle which is centered on the axis of the spindle.
  • the ring 10 can be circular, in which case its axial projection is an ellipse more or less flattened according to the angle of inclination of the ring relative to the axis of the spindle.
  • the ring 10 extends over only a part of the length of the coil 6, for example at most over its first third, and its upper part is situated substantially at the entry of the hollow spindle 3.
  • the ring 10 is inclined and located axially only in the first part of the coil 6, it prevents the formation of the usual balloon of large amplitude when the wire 7 comes from the lower end of the coil, while it does not interfere with the unwinding when the wire 7 comes from the upper end of the spool, because then it is not in contact with the wire.
  • the ring 10 when it cooperates with the wire 7, the ring 10, by the friction which it nevertheless exerts on the wire, retains any free fibers which may have caught on and separates them from the wire.

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Neigungswinkel (α) der Hauptebene des Rings (10) gegenüber der Achse der Spindel zwischen 5° und 80° liegt und vorzugsweise etwa 30° beträgt.
3. Einrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der Ring (10) kreisförmig ist und daß sein Mittelpunkt auf der Achse der Spindel (3) liegt.
4. Einrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der Ring (10) eine Ellipse ist, welche so angeordnet ist, daß ihre axiale Projektion ein Kreis ist, dessen Mittelpunkt auf der Achse der Spindel (3) liegt.
5. Einrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß der obere Teil des Ringes etwa auf gleicher Höhe mit dem Eintritt des Fadens in die Spindel liegt.
6. Einrichtung nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß sie zu einer Anlage für Fadenumspinnung gehört, in welcher der von der Spule (6) kommende Umspinnungsfaden (7) zusammen mit einem zu umspinnenden Faden (2) in die Hohle Spindel (3) hineinläuft.
