Definitions

  • the present invention relates to an "open-end" spinning process and apparatus.
  • the shredder constituted by a cylinder furnished with teeth or needles, may have its axis of symmetry and rotation coincident with the axis of symmetry and rotation of the rotor; in this case we say that the device is coaxial. If these axes are different, and in particular left, the device is said to be biaxial.
  • the defibrator partially penetrates the rotor.
  • the fiber ribbon is brought into an area, fixed in space, where the fibers are brought into contact with the teeth of the shredder and are extracted from the ribbon. They are then conveyed on the teeth of the shredder for a certain time then, by the effect of centrifugal force, detach from the teeth and are projected into the rotor in the groove from which they gather.
  • the exact location of the space where the fibers detach from the shredder and are projected into the rotor is difficult to know and in fact depends on several factors, such as: speed of the shredder, type of teeth of the shredder, type of fibers, suction phenomena created by the rotation of the rotor, etc. It is therefore accepted that for a given operating regime, the fibers are deposited in the rotor in a given but unknown area, which will be called hereinafter "fiber deposition area". This area refers to space and not to the rotor since it rotates continuously.
  • the fibers when they detach from the shredder, cannot enter directly into the rotor, since the shredder and the rotor are more distant from each other. They are then conveyed, between the defibrator and the rotor in a channel by a movement of air which collects them, at the exit of the defibrator which is also the entry of the channel and leads them to the exit of the channel which is also the rotor inlet.
  • Fiber deposition area refers to space and not to the rotor, since it rotates continuously.
  • the device is coaxial or biaxial, there is therefore a “fiber deposition zone” where the fibers are deposited in the groove of the rotor. Under determined conditions, this zone is fixed in space.
  • the technique for forming the wire is well known: the end of a wire is introduced into the rotor, through the end piece. This end, by centrifugal force, goes towards the groove of the rotor and comes to mix with the fibers constituting the ring of fibers generated by the fibers coming from the shredder. The wire is then introduced into the delivery device, which then attracts it outside the rotor. The end of the wire which has mixed with the ring of fibers present in the rotor is driven in rotation by the rotor and twists; this twist is communicated to the ring of fibers present in the rotor, with which the end is in contact. The ring of fibers opens and one of its ends is intimately linked, by the effect of the twist, to the end of the wire and the two merge.
  • the shredder constantly sends fibers into the rotor to reconstitute the ring of fibers, and the delivery device constantly extracts from the rotor this ring of fibers which has become thread by the effect of the twist.
  • the ring of fibers which becomes a thread by the effect of the twist, detaches from the groove of the rotor in a very precise zone of the rotor before moving towards the outlet nozzle.
  • This zone which will be called hereinafter “wire formation zone” is not fixed relative to the rotor. Indeed, if this area was fixed in the rotor, the wire could not be delivered.
  • the "wire formation zone” therefore moves continuously in the rotor, with a speed such that the difference between the absolute linear speed of this wire formation zone and the peripheral speed of the rotor at its groove is equal to the speed of delivery (or production) of the wire.
  • the object of the present invention is to remedy this drawback, to eliminate the phenomenon of "bundling” and therefore to make possible the spinning of long fibers on an apparatus of the "open-end” type, comprising a supply device, a defibrator, a rotor, a rotary channel conveying the fibers from the output of the defibrator to the rotor, an output nozzle, a defibrator device and a winder device, apparatus in which the ribbon is first of all disaggregated in the defibrator that the rotary channel carries only individual fibers.
  • the process which is the subject of the invention is distinguished in that the “fiber deposition zone” is given a speed equal to that of the “wire formation zone” so that the fibers coming from the shredder cannot be deposited on the wire in formation.
  • This shredder is shown schematically and by way of example at 1 in FIG. 1.
  • the principle of the invention is to give the “fiber deposition zone” represented at 11 a speed equal to that of the “wire formation zone” represented at 13 and to arrange these zones so that the fibers 10 coming from the shredder 1 cannot be deposited on the wire in formation 14.
  • a channel 2 is provided which conveys the fibers 10 from the outlet of the shredder 1 to the rotor 4; this channel 2 is located in the axis of the rotor 4.
  • the channel 2 is extended by an element 3 comprising a bent conduit 3 1 which deflects the fibers 10 coming from the channel 2 and directs them towards the groove 5 of the rotor 4; this element 3 is driven at the speed of rotation of the "wire formation zone" 13, either by synchronizing by electrical or electronic means the speed of element 3 and the speed of the "wire formation zone” 13 ( Figure 2) or by forcing, by mechanical means, the wire in formation 14 to drive the bent conduit 3 1 for feeding the fibers.
  • a means 9 is provided, consisting, for example, of a rod in the shape of a "finger” fixed on the element 3 and extending sufficiently towards the bottom of the rotor 4 to be in the path of the wire in formation. 14, so that the latter, in its rotation, is forced to abut against this rod and consequently to cause the element 3 to rotate.
  • the “wire formation zone” 13 and the outlet of the bent conduit 3 1 for supplying the fibers are offset so that these fibers cannot deposit on the wire in formation 14 in the “wire formation zone” 13 .
  • the element 3 is mounted so as to be able to rotate freely, for example by a ball bearing 8 on a part 7 itself integral with the rotor 4.
  • the part 7 secured to the rotor 4 is also rotated at the same speed.
  • the wire 14 then no longer has to communicate to the element 3 for deflecting the fibers except the speed equal to the difference between the speed of the “wire formation zone” 13 and the speed of the rotor 4.
  • the invention is not limited to this type of relationship, but applies to any embodiment based on the same principles.
