Method and device for the treatment of fiber tapes »in particular made of wool

Known combing methods for wool include several Operations such as washing, coating, stretching and doubling the slivers, for example by an "intersecting" machine, the actual combing and a treatment in a "vide pot" machine, as well as smoothing and post-processing through fine stretching » These operations are lengthy, costly and complicated, and have not yet been simplified will,

Difficulties arise in particular during the smoothing process in which the wool is degreased and the tape is made shiny.

Smoothing is done either before or after combing, this process consists in letting the slivers - in Layers folded - to be immersed in one or two kettles of hot water and then between two Rollers heated by steam or electricity can be dried.

The disadvantages that arise are that fiber residues settle on the fiber layers in the form of knots, the irregularities of the strands, later Cause tearing when spinning and blemishes when dyeing can. ■

The invention is intended to overcome these difficulties; she sees a method for combing fibers »in particular of wool before. According to this method, the fibers are placed during at least one process of the complete treatment of the action of steam, whereby the fibers are set lengthwise and stretched can be. The otherwise usual smoothing process becomes superfluous and a fiber strand is achieved of good quality.

The invention also relates to an apparatus for the implementation of the extended or a similar procedure, as well as an appendix to it Implementation and includes, for example, "intersecting" or "vide pot" machines.

Finally, the invention also relates to the combed fibers themselves, in particular the wool fibers that are used in the implementation of the procedure.

The invention is explained in more detail using the exemplary embodiments shown in the drawing!

Fig. 1 shows a plan view of the work sequences in combing;

2 shows the smoothing device in longitudinal section; FIG. 3 shows the side view of FIG. 2.

The invention pursues the purpose of fiber residues to avoid the slivers and thus irregularities,

The invention also leads to a reduction in treatment costs, since the manual work required for smoothing is no longer necessary and maintenance of the smoothing device is no longer necessary.

The invention also makes slivers of be. Excellent quality in terms of regularity and moisture level.

The fiber strands are made into the method of the invention first washed in the container in order to remove the fat from the fibers, in the first treatment stages in hot, soft water, later in hot water mixed with detergents.

After washing the slivers in the device 2 by pressing between two rollers, the moisture removed and then the fibers are further dried.

Then in the device 3 the cardage takes place, whereby the different types of fiber intimately mixed and placed at least approximately parallel. After painting, the slivers have a homogeneous shape and uniform thickness.

The fibers are then prepared for combing in devices 4, 5 and 6 of the "intersecting" machine. The slivers are stretched, doubled and stretched again. One achieves on this Make a regular cross-section of the tape and a perfect parallelism of the fibers (uniform of the slivers).

The tapes prepared in this way are then placed in the Machines 7 combed in order to then be stretched and doubled in a stretching machine, system "vide pot". The treatment is finally ended on a fine straightener 9.

According to the invention, the slivers during the described treatment of the action of Exposed to steam. For this purpose, the fiber strand passes through a tubular, double-walled device 10. The inner wall 11 is perforated to allow the steam to penetrate through the slivers. The steam is in unlimited amount introduced into the cavity 12 between the two walls of the device "

The perforated inner wall 11 of the device 10 is on both ends funnel-shaped to facilitate the entry and exit of the slivers.

At the sliver exit end of the device 10 is a Vessel 13 attached to collect condensation. The condensed water can flow away through an opening 13.

As can be seen from Fig. 3, the outer wall the device 10 has two further openings, namely a nozzle 14 on the upper part for the entry of water vapor into the space 12 and a nozzle 15 at the lower part for the exit of the cooled steam.

This steam treatment allows the fibers to stretch to length to be determined and stretched »but in particular they smoothed and moistened.

The steam treatment according to the invention can take various forms Stages of the process can be made, for example the device 10 at 16 and 17 at the inlet the second and third stretching device ("intersecting" machine) or at 18 at the inlet of the "vide pot" machine 8 can be arranged. Finally, the steam treatment can also take place before the treatment in the machine 9 (Feinstrecker) done at 19 »

The method according to the invention thus enables the Use of steam in the various stages of preparation and post-treatment when combing fibers and allows slivers to be achieved that are more regular and are moistened better than could previously be achieved by other methods.

Of course, the invention is not restricted to the example described above A person skilled in the art is easily able to implement the invention in
