Description

ROTATING NOZZLE OR TEXTURING NOZZLE AND

DEVICE FOR TREATING YARN

The present invention relates to a nozzle and a Vorrich ^¬ device for treating yarn, in particular a swirl nozzle or a texturing.

Various nozzles and devices for treating yarn are known in the art. Typically, these SI ^¬ sen or devices are divided into two groups, on the one hand in nozzles and devices for producing knotted yarn, on the other hand, in the nozzle and apparatus for texturing yarn, so-called texturing. Nozzles for producing knotted yarn are swirl nozzles. The present invention is applicable in both fields.

Various nozzles for treating yarn are known in the art. For example, WO 97/11214 A1 shows a texturing nozzle. Another Texturierdüse is in the WO

2004/097087 AI described. WO 2006/099763 Al discloses a Verwirbelungsdüse for the production of knotted yarn. Another nozzle for treating yarn is disclosed in Taiwan Utility Model TW M50922U. An overview of Behandlungsmetho ^¬ of filaments and an overview of nozzles for manufacture of knotted found in DE 10 2008 008 516 AI. This discloses an apparatus for simultaneously treating a plurality of multifilament yarns with parallel yarn channels.

All of these known devices of the prior art are intended and suitable for treating yarn of the same thread thickness (dtex). This means, mutatis mutandis, each of the Dü ^¬ senplatten from the prior art has an application rich in yarns or threads or a filament population lying between a certain lower and upper limit.

The nozzles of the prior art are disadvantageous in that, for the processing of yarns with a thread thickness, which is ^¬ from this predetermined range, the nozzle must be replaced.

It is therefore an object of the invention to overcome the disadvantages of the prior art. In particular, a nozzle and a

Device can be provided, which makes it possible to treat threads, filaments and yarns over a wider range of applications without a loss of quality occurs. These and other objects are achieved by the devices defined in the independent claims. Further embodiments emerge from the dependent claims.

In the following, the invention will be explained by way of example with reference to yarn. However, the invention generally relates to the ^treatment of threads, filaments or filament bundles and the term yarn is used to represent this.

A nozzle according to the invention for treating yarn, in particular an entanglement or texturing, comprising at least a first ^¬ yarn channel and at least one second Garnka ^¬ nal. The first yarn channel has a first cross section and the second yarn channel has a second cross section. The first yarn ^¬ channel cross-section and the second Garnkanalquerschnitt have a mutually different dimension and / or a mutually different shape. This makes it possible to provide a nozzle which can treat yarns in a ^wider range of applications.

A yarn in a yarn thickness of 25-80 dtex behan ^¬ spindles and with the second yarn channel can, depending on the application, for example, with the first yarn channel, a yarn in a yarn thickness of 80 to 150 dtex. Thus, threads of a total of 25 to 150 dtex can be treated with the nozzle according to the invention. That is, the field of application is approximately doubled over a prior art nozzle. As an example, here is a rectangular Garnkanalquerschnitt with a dimension of 1.0mm depth x 1.6 mm width mentioned as a cross section of the first Garn ^¬ channel, and as a cross section of the second Garnkanals a rectangular Garnkanalquerschnitt with a dimension of 1.15mm depth x 1.8 mm width.

The yarn channels may not only have different cross sections ^¬ but also different dimensions or shapes of vortex chambers, for example swirl chambers as described in WO 2006/099763 described. The dimension of the vortex chamber affects the number and characteristic of knot formation. It can therefore eg two yarn channels for the same yarn count, but under ^¬ schiedliche node characteristics are provided.

Preferably, the nozzle has a base plate and a cover plate connected or connectable to the base plate. By a base plate and a cover plate a closed Garn ^¬ channel cross section can be generated.

The first yarn channel and / or the second yarn passage may be preferably formed entirely before ^¬ in the base plate or in the cover plate. This makes it possible to in each case completely finished the yarn duct in one of the two plates and to the second plate in Wesent ^¬ union unprocessed. Both the production and the installation of the nozzle is simplified. It is prior ^¬ some way, if one of the two plates (base plate or cover plate) is worked, that is, having a plane opposite the jewei ^¬ then the other plate surface. Positioning errors of the base plate to the cover plate are thereby no effect on the yarn channel.

The nozzle is preferably mountable in a first and in a second position. In the first position, the first yarn channel is in the intended position relative to a yarn feed, and in the second position the second yarn channel is in the intended position.

This makes it possible, depending on the yarn to be treated (or, depending on the yarn thickness to be treated), to use the first or the second yarn channel.

This makes it possible to adjust the nozzle in a simple manner to the per ^¬ weiligen requirements. Preferably, the first yarn channel and the second yarn channel are arranged symmetrically about a pivot point. In this case, by ^pivot point is meant a virtual axis of rotation which is defined by the end position of the nozzle with respect to, for example, a nozzle holder and its fastening elements. An analogous rotation axis is shown, for example, in FIGS. 8a to 8d of WO 2006/099763. This disclosure is incorporated by reference. A symmetrical arrangement of the yarn channels means that they have the same distance to the axis of rotation. This means, that the center planes of the yarn channels in a plane perpendicular to the rotation axis equally spaced from this ^¬ are arranged. This makes it possible to mount the nozzle in a first installation position and in a second installation position rotated by 180 ° with the relative position of the yarn channel intended for use being unchanged relative to a yarn feed. In a preferred embodiment, two or more first and second yarn channels may be alternately in the nozzle at ^¬ sorted. Likewise, it is conceivable to arrange a plurality of first depending Garnka ^¬ ducts and a second plurality of yarn channels in a mutually ^¬ about the axis of rotation opposite side. It is also possible to provide more than two different dimensions and / or shapes in embodiments having more than two yarn channels.

This allows the parallel processing of a plurality of identical threads first thread thickness with the first yarn channels and the processing of several identical threads second thread thickness with the second yarn channels.

Preferably, the nozzle is made of a ceramic material. Ceramic material extends the life of the nozzle.

The first yarn channel and / or the second yarn channel have preferably ^¬, to a vortex chamber. A preferred geometry of a yarn treatment channel with a swirl chamber (blown air duct extension) is described, for example, in WO 2006/099763. The Garnkanalquerschnitt can be formed semicircular, U-shaped or V-shaped. Another aspect of the invention relates to an apparatus for treating yarn comprising a nozzle as described herein. The nozzle is mountable in a first and in a second mounting position in the device. In the first assembly position, the first yarn channel is in the intended position and in the second assembly position, the second yarn channel is in the intended position.

This makes it possible to provide a Garnbehandlungsvorrich- device with respect to the yarn treatment devices of the prior art wider application area.

The nozzle is preferably arranged rotatable or displaceable in the device. By rotating or moving the mounting position of the nozzle can be easily changed. The displacement or rotation can also be controlled automatically and be done for example by an external electrical signal or by pneumatics. The nozzle is then installed in a texturing machine which generates corresponding control commands.

This facilitates the changeover from a first yarn thickness to a second yarn thickness. This means that the switching from egg ^¬ nem yarn channel on the other yarn channel and vice versa is simplified.

The device preferably has a base body and a lever device, wherein the base body is designed to receive the nozzle. The lever device can be brought into operative connection or in operative connection with the nozzle at least at a first articulation point, such that the nozzle can be adjusted by the lever device relative to the main body. As a result, the nozzle can be brought from a first position into a second position. On Example of such a base body having a Hebelvorrich ^¬ tung 2006/099763 Darge provides ^¬ in Figures 7a to 7f WO. This disclosure is incorporated herein by reference. This makes it possible to bring the nozzle in two intended positions. In a first position, the yarn is threaded into the nozzle and in a second layer, the yarn is treated.

The lever device can be brought into operative connection with at least the first articulation point and a second articulation point of the nozzle, wherein in connection with the first articulation point of the first yarn channel and in the connection with the second articulation point of the second yarn channel each in a same relati ^¬ ven position based on the main body is arranged.

This allows a simple displacement of the nozzle, so that depending on the articulation point of one of the two yarn channels is in intended use. This makes it easy to set the nozzle geometry allows the per ^¬ weiligen requirements.

Preferably, the device has a sliding carriage for receiving the nozzles. The nozzle is at least partially arranged on the sliding carriage, wherein the first articulation point is preferably arranged on the sliding carriage.

This simplifies the production and the geometry of the nozzle, since the active connections for the articulation points are not formed on the nozzle but on the sliding carriage.

Preferably, the nozzle is rotatably mounted from a first position to a second position on the sliding carriage. This allows, as described herein, the simple rotation of the nozzle.

The first articulation point and the second articulation point are preferably arranged on the sliding carriage. The nozzle is thus brought into two positions, which can be brought again in two positions by the rotatable arrangement of the nozzle on the sliding carriage. With such a device a four-fold Verstel ^¬ development of the nozzle is possible. It is thus possible, in addition to a first and a second Garnkanalquerschnitt also provide a third and a fourth Garnkanalquerschnitt to further increase the scope of the nozzle and the device.

The invention will be explained by way of example with reference to the following figures. They show schematically:

FIG. 1 a: a three-dimensional view of a nozzle according to the invention with two different yarn channels,

Figure lb - ld shows a cross section of different execution ^¬ embodiments of the invention with different shapes and sizes of yarn channels,

The yarn channel 1 is here V-shaped, the Yarn channel 2 U-shaped. In the nozzle 100 of FIG. 1c, the areas of the cross sections of the yarn channels 1 and 2 are different. However, it is also possible, as in Figure la to use two yarn channels with congruent cross section but un ^¬ terschiedlichen cross-sectional areas. For example, two V-shaped or two U-shaped cross sections are usable. Different cross-sectional shapes with different cross-sectional areas are also possible. Further, the yarn channels may differ along the yarn movement direction.

For example, one of the yarn passages may have a vortex chamber on ^¬, währendem the other yarn channel formed continuously is. It is also conceivable to provide only different vortex ^¬ chambers with otherwise identical yarn channels.

FIG. 1 d schematically shows a yarn plate of a nozzle 100 with a plurality of first and second yarn channels 1, 2

Moving along the direction of the arrow, the first or the second yarn channels may be aligned with respect to a group of supplied yarns. Figure le shows a plan view of a nozzle 100 with a ers ^¬ th and a second yarn duct 1, 2 of different cross section and arranged in alignment at different places swirl chamber 7. The nozzle is rotatable about a pivot point 3, so that either the first or the second yarn channel is supplied with a yarn G.

FIG. 2a shows the installation of a nozzle 100 as shown in FIG. ^1e in a sliding carriage 6. For a better overview, the same components in FIGS. 2a to 2d are referred to only once.

FIG. 2b shows a perspective view of FIG. 2a. The nozzle 100 is placed on the sliding carriage 6 for insertion into the sliding carriage 6 in the arrow direction (FIG. 2 a), so that first projections 101 (in FIG. 2 c on the right) engage behind first undercuts 101. The nozzle 100 is in this case once it has reached the end position of the placing operation, down ge ^¬ suppressed (Figure 2c and 2d), so that it jumps with their second pre ^¬ 101 (in the figures on the right side) in the reciprocating terschnitte 61 can intervene. Thereafter, the nozzle 100 is in the intended end position (Figure 2d).

Depending on the application, the first yarn channel 1 or the second yarn channel 2 must be brought into the position of use with respect to a yarn feed (not shown). For this purpose, in the first section (FIG. 2 b), the nozzle must be inserted either as shown or turned through 180 ° around the axis of rotation 3 (see FIG. After carrying out the step according to FIG. 2 c, the corresponding yarn channel 1 or 2 is then in the intended position after that.
