Definitions

  • the present invention relates to a method for spinning a thread with the aid of an open-end device having a spinning rotor, in which the fibers are fed to a fiber guide surface which widens in the direction of the spinning rotor and from which the fibers overlap a gap on one another expanding sliding surface of the spinning rotor, and a device for carrying out this method.
  • the object of the present invention is to improve the known principle of fiber stretching and thus to improve the structure of the yarn and to avoid fiber losses.
  • this object is achieved in that an air stream is passed through the gap into the interior of the spinning rotor and is then discharged from the interior of the spinning rotor without having to pass through the gap again.
  • an air flow directed into this space ensures that the fibers overcome the gap and on the inner wall of the spinning rotor are deposited, from where they are then fed in the usual way to the fiber groove for spinning.
  • a rotating air flow is created along the fiber guiding surface which results from the rotation of the spinning rotor and which conveys the fibers fed to the fiber guiding surface to the end of the fiber guiding surface facing the gap.
  • This circulating air flow then combines with the air flow introduced into the spinning rotor through the gap and then becomes with it discharged from the space enclosed by the fiber guide surface and the spinning rotor without passing through the gap again at any point on the circumference of the spinning rotor. It has been shown that the air to be discharged reaches the center of the space enclosed by the fiber guide surface and the spinning rotor and thus does not interfere with the fiber transport to the spinning rotor.
  • This type of fiber feed and air control leads to a substantial improvement in the yarn structure and to a significantly better utilization of the load-bearing capacity of the spun fibers and thus to a substantial increase in yarn strength with a better appearance.
  • the air flow entering the interior of the spinning rotor through the gap can be generated in various ways. According to advantageous refinements of the method according to the invention, this air flow is generated by compressed air which is supplied to the outer circumference of the gap, or alternatively by a suction air flow which is discharged from the spinning rotor. It is also possible to generate the suction air flow by rotating the spinning rotor. In this case it can be provided that the suction air stream generated by the rotation of the spinning rotor and discharged from the spinning rotor is again introduced into the spinning rotor through the gap, so that a circulation flow is created.
  • the air flow is discharged with respect to the gap to the side from where the fibers are fed, the air flow essentially being expedient in relation to the circular area enclosed by the fiber guide surface is discharged diametrically opposite from the fiber feed.
  • the air flow essentially being expedient in relation to the circular area enclosed by the fiber guide surface is discharged diametrically opposite from the fiber feed.
  • the fibers are fed to the fiber guide surface by means of an air stream, a large part of this air stream being removed from the spinning device with sharp deflection, while the remaining part of this air is carried together with the fibers are fed on a spiral path to the widened end of the fiber guiding surface, from where the fibers are transferred over the gap to the sliding wall of the spinning rotor, the air flow entering through the gap preventing the fibers from escaping through the gap, whereupon the fibers reach the fibers groove for spinning in a known manner, while the air guided through the gap into the interior of the spinning rotor is discharged from the spinning rotor without passing through the gap again.
  • the structure of the yarn can be improved and its strength increased in a particularly simple manner.
  • the air flowing into the spinning rotor receives a component directed towards its bottom. In this way, the air flowing into the spinning rotor blows the fibers leaving the fiber guide surface in the direction of the inner wall of the spinning rotor and thus favors their placement on the inner wall of the spinning rotor and their delivery to the fiber collecting groove.
  • the air flowing through the gap into the spinning rotor is expediently adapted to the material to be spun.
  • This adjustment advantageously takes place by changing the gap width. In this way it is not necessary to change the output of an overpressure or underpressure source, so that the air balance which has an effect on the spinning process will not change significantly.
  • the adjustment of the gap width can be achieved in a simple manner by relative axial adjustment of the fiber guide surface and the spinning rotor.
  • a device for generating a pressure gradient is assigned to the gap, which device causes an air flow flowing through the gap into the interior of the spinning rotor. This prevents fibers from being removed from the spinning process.
  • the device for generating the pressure gradient is formed by a part of the area surrounding the gap.
  • the vacuum source acting in the spinning rotor can be an external vacuum source or can also be formed by at least one ventilation opening arranged eccentrically in the spinning rotor.
  • the vacuum source acting in the interior of the spinning rotor is preferably formed by the inlet opening of a suction line which is arranged on the same side with respect to the gap as the fiber feed device. It has been shown that in this way the air pressure applied to the outer circumference of the gap can assume a lower value than otherwise in order to generate the required pressure drop from the outside in, so that it may be sufficient, the outer circumference to connect the gap to the atmosphere so that an excess pressure source connected to the outside of the gap can be dispensed with.
  • a particularly favorable air flow can be achieved according to the invention in that the fiber feed device has a fiber feed channel which is eccentrically inside of the ring-shaped fiber guide surface ends, the inlet opening of the suction line being in the other half of the circular surface enclosed by the ring-shaped fiber guide surface.
  • the fiber feed device has a fiber feed channel, it is expediently provided that its end, like the inlet opening of the suction line, is arranged in a projection of a cover, which projects essentially concentrically into the space enclosed by the ring-shaped fiber guide surface.
  • the fiber guide surface is preferably not rotatable, the ring-shaped guide body expediently being an integrated part of a cover, which closes off the housing accommodating the spinning rotor.
  • the spinning rotor and the fiber guide surface are axially adjustable relative to each other.
  • this air flow can also be oriented more or less strongly towards the inner wall of the spinning rotor.
  • the intermediate wall can be arranged on the outer wall of the spinning rotor and extend directly to the inner wall of the housing, so that on the one hand a good seal is achieved without the rotor being impaired in its rotation on the other hand.
  • this makes the interchangeability of the spinning rotor easier, which is particularly important in the case of spinning rotors which are supported with the aid of support disks.
  • the integrated intermediate wall makes the spinning rotors relatively heavy, which leads to an increased drive energy requirement. Therefore, the partition is preferably carried by the housing, as far as constructively possible.
  • the peripheral area of the spinning rotor in which there is at least one ventilation opening, is connected within the housing to the peripheral area of the gap between the spinning rotor and the fiber guide surface.
  • the intermediate wall from segments which are used to regulate and pass through the at least one ventilation opening - lü ⁇
  • the air flow entering the gap in the spinning rotor can be adjusted relative to one another in the circumferential direction of the spinning rotor.
  • the inevitable, in some cases significant, loss of fiber in known devices of the type described can be avoided without having to accept disadvantages with regard to yarn structure and yarn strength. Rather, it has been shown that the yarn structure is considerably improved compared to conventional rotor yarns.
  • the load-bearing capacity of the spun fibers is better utilized compared to conventional rotor yarns, which results in an increase in yarn strength. Improving the yarn structure also results in a better appearance of the yarns obtained.

  • the function of the rotor spinning device according to the invention is as follows: In a disintegration device, not shown, the fibers are combed out of a fiber band with the aid of the clothing tips of the disintegration rollers and transported as individual fibers in the fiber feed channel 19, where they form a stream of individual fibers together with the flowing air.
  • the flow of the individual fibers follows the direction in which the mouth of the guide channel 19 is directed.

  • the air stream 30 which has entered the spinning rotor 1 through the annular gap 17 is deflected by the rotating spinning rotor 1 in such a way that in this stream a rotational component outweighs the directional component given by the axial direction of the annularly arranged gap 17.
