Description

Device for the treatment of rope-shaped textile goods

The invention relates to an apparatus for treating strand-like textile material in the form of a circulating fabric rope, which is set in rotation during at least a part of its loading ^¬ treatment.

Such a device, as described for example in DE 10 2013 110 492 B4, has a closable treatment container and a transport nozzle arrangement, which can be acted upon by a transport medium flow. The transport nozzle assembly is adjoined by a transport path, via which the product strand can be moved by the transport nozzle arrangement in a transport direction. The transport nozzle arrangement has a transport nozzle with a nozzle inlet opening and a nozzle outlet opening for the continuous goods strand, between which a nozzle gap for the transport medium is delimited. This nozzle gap is adjustable, i. adjustable in its nozzle width.

In another device of this type, which has a similar structure in principle (DE 10 2007 036 408 B3), a transport nozzle is provided which has two in the transport ^¬ direction one behind the other nozzle column, which is in the treatment of certain textiles of advantage especially as the nozzle gaps are adjustable in their gap width. In the operation of such devices, for example, dyeing systems with goods transport in strand form, unfavorable settings of the operating conditions can lead to standstill stoppages, which are caused, for example, by knot or loop formation in the product strand or by simultaneous drawing in of two or more product strand loops.

In many cases, manual intervention is required to get the goods moving again. If the fault of the fabric rope run at high temperatures, above a temperature at which must be locked for safety ^¬ set designed as a pressure vessel Behandlungsbe ^¬ container, it is necessary to interrupt the treatment-process and ERS the temperature ^¬ lower, and then correct the web runout at lower temperatures suitable for manual intervention. Depending on the progress of the treatment process, the desired treatment ^effect may under certain circumstances no longer be achieved.

In practice, dyeing with transport of goods in rope form are known in which this problem is resolved by or reduced to an additional second nozzle is provided which is traversed by the rope, and which is designed such that it stood in the switched-to ^¬ a reverse the normal transport direction directed transport effect exerts. In normal goods flow, this additional nozzle is ineffective. In the case of stepping on ^¬ a disorder of the rope run, it is acted upon from ^¬ switched transport jet with a transport medium, so that the rope is supported against the normal direction of transport. But this solution is through the use of two independent autonomous nozzles, apart from the increased space requirement in the treatment tank, costly. The nozzles are also provided with a structurally predetermined nozzle gap, so that for a change in the nozzle characteristic, as required in the treatment of different qualities of goods occasionally, the nozzles must be replaced, which is associated with considerable effort.

The treated in such devices with a continuous strand of goods strand of goods is endless. Before the treatmen ^¬ lung in the treatment tank, a corresponding length of the fabric rope is introduced, the ends of which are sewn together before the start of treatment. After completion of the treatment of the fabric strand must be separated again at the interface, so that it can be removed from the Behandlungsbehäl ^¬ ter on the open loading opening. For the required seam search, a magnet is usually introduced into the fabric strand in the seam area. At the end of the treatment process, the transport of Wa ^¬ renstrangs be stopped and searched the seam. If the magnet placed in the seam area reaches a sensor, the goods drive is switched off. Due to the high speed of the circulating strand of goods, however, the detected seam is transported further with the magnet until the drive system comes to a standstill. This makes it necessary to Wa ^¬ renstrang withdraw manually to too much transported rope length and to seek the magnet and thus the seam manually. Only then is the seam accessible to the operator and can be opened for the unloading step. This process takes a relatively long time and is therefore costly. Here it would be desirable, the strand of goods automatically at low speed against the Transport direction to be able to return, so that the seam and the magnet for the accessing via the loading opening of the treatment container operator can be reached directly.

As already mentioned, it is for a group of Southwestern ^¬ tilwaren desirable, a transport nozzle arrangement to employ at least two columns of nozzles, which are arranged in transport direction behind the other ^¬. In general, the gap widths of these nozzles are relatively small so that a relatively low volume flow of the transport medium is used in conjunction with a high nozzle pressure. To operate a treatment device of the type in question with such a nozzle with multiple columns, a mechanical nozzle change is often required. The conversion results in additional personnel costs and Anla ^¬ genstillstandszeiten and reduces the productivity of the plant. There is therefore a need to avoid this ^addi tional effort and the cost of the additional nozzles.

The object of the invention is therefore to provide a device of the type mentioned for the treatment of extruded textile goods in the form of a circulating strand of goods, in which the needs explained above are remedied and which is characterized by a Transportdü ^¬ senanordnung that without major additional effort or space required on the continuous strand of goods can act accordingly.

To solve this problem, the device according to the invention has the features of claim 1. The new apparatus for treating strand-like textile material in the form of a circulating fabric rope with the aforementioned features is characterized in that the transport nozzle arrangement has a transport nozzle with egg ^¬ ner nozzle inlet opening and a nozzle outlet for the passing fabric rope, between which at least two nozzle column for the transport medium are limited. At least one of the nozzle gaps is adjustable in its gap ^¬ wide. In addition, at least one nozzle gap for conveying the continuous goods strand in the transport direction and at least one nozzle gap for conveying the continuous goods strand in a direction opposite to the transport direction are arranged by the nozzle columns. For this purpose, control means are provided to drive via a corresponding control of the nozzle column, the continuous strand of goods either in the transport direction or in the direction opposite this direction.

In an advantageous embodiment, the

Transport nozzle three nozzle column, one of which is adapted to promote the continuous strand of goods against the transport direction and which are suitably formed independently variable in their gap width. At least one of the nozzle gaps can be infinitely adjustable, but embodiments are also conceivable in which this adjustment takes place gradually in one or more nozzle columns.

The new device allows it to be able to drive the continuous material strand with different intensities forward and backward, for example, with Minim ^¬ least two narrow gaps, and alternatively, with a large gap in the "forward direction" and with one or more Column is avoided in "backward direction," which will be preceded by the corresponding closure of the opposite of the intended conveying direction acting nozzle column, the nozzle column working against each other. The control of the nozzle column can be automated with little effort, the nozzle column and coupled to this a ^¬ directions of control means can be inexpensively placed in a unit ^¬ handy nozzle housing over it distinguishes itself out through a small footprint in the treatment tank.

In an advantageous embodiment, the device has a nozzle housing aufwei ^¬ the nozzle inlet and the nozzle aufwei ^¬ sendes, in which at least one at least one of the nozzle column delimiting nozzle member is adjustably arranged, which can be controlled by the control means. This nozzle element is expediently designed in the form of a closed frame or ring, so that there is an annular gap surrounding the continuous strand of goods.

As argued above, at the end of the treatment process, the seams are opened each circulating fabric ^¬ strand and extended the goods from the treatment tank. In practice, depending on the size of the apparatus, one to six strands of ^fabric are usually treated simultaneously. At the end of the treatment process the seams of one to six ropes of be searched using sewn-Mag ^¬ items one by one. For treatment plants, for example, dyeing plants with, for example, two to six strands, the drive or transport medium flow of each transport nozzle with its own shut-off valve is bar ^¬ bar. If a seam is found over its magnet, the Drive stream of the corresponding transport nozzle shut off by the associated valve and the transport ^{reel is} switched off ^¬ . The product strand is braked and comes to a standstill after approx. 3 m to 15 m, depending on the respective product circulation speed. By turning on the "reverse" direction of transport, the otherwise necessary manual retraction of possibly hot material strand can be performed automatic ^¬ table, which the manual effort of unloading is significantly reduced. In another part Cling ^¬ embodiment, the transport jet can take over the function of the shut-off valve at the same time. for this, the column of nozzles to promote continuous material strand in the transport direction and in the direction opposite to the transporting direction are closable and controllable by the control means in terms of a common ^¬ seed closure of the nozzle column. the construction of the fabric rope transport system can thus be significantly more cost executed ^¬ cheaper.

The shape of the nozzle inlet and the nozzle outlet is the same as the shape of the nozzle elements not subject Begrenzun ^¬ gen. It may be circular, oval, rectangular, square or polygonal depending on the particular requirements, to mention but a few examples.

Advantageous developments and refinements of the new device are the subject of dependent claims.

The illustrated in Figures 1, 2 as an embodiment of a device according to the invention long-storage machine is used for the treatment of rope-shaped textile product in the form of an endless strand of goods, which is at least during part of the treatment in circulation.

The machine includes an elongated substantially tubular treatment container 1, which is 3 identical diam ^¬ sers of a larger cylindrical tube portion 2 and a shorter likewise cylindrical tube portion, which is connected via a keilförmi ^¬ ges in the side view of the intermediate tube section 4 to each other and ends with trays, for example, Dished or basket bottom sheets 5, 6 are closed. The releasably secured basket sheet floors 6 is provided with a leading into the container interior loading door 7. The axes of the two pipe sections 2, 3 include an obtuse angle of 165 ° with each other. At its front end of the treatment tank 1 is supported by two on opposite sides of the pipe section 3 fixed feet 8, which are mounted ver ^¬ pivotable about a horizontal axis of rotation 9 on stationary bearing blocks 10.

At the rear end of the treatment tank 1, a lifting device acting on the outside of the longer pipe section 2, which is schematically illustrated at 11, is provided, which operates with a lifting spindle (not shown) or likewise with lifting cylinders (not illustrated) and forms actuating means for the treatment tank 1. When standing in a lowered position (not shown) Treatment tank, the liquid contained in this can converge on the container bottom to a lowest point 12 in the region of the intermediate tube part 4 and deducted from this lowest point. In its respectively set tilt position of the ^{Behandlungsbehäl ¬} ter 1 by the actuating means of the lifting device 11 can be locked, which is indicated by detents 13.

In the treatment tank 1, as can be seen in particular from Figure 2, a transport nozzle assembly 14, an adjoining transport path 15 and a trough-shaped or trough-shaped elongated sliding floor 16 are arranged, which allow a schematically indicated at 17 continuous strand of goods in circulation , The sucked from the transport nozzle arrangement 14 fabric rope passes through the transport path 15 to the Warenstrangein- to a rope outlet side 20 to the backing side 18 of a one at 19, indicated abgetafeltes Wa ^¬ renstrangpaket receiving storage portion 210 of the loading ^¬ treatment container 1, in the running side of the Warenstrangein- 18, the abgegedafelte goods string package 19 carrying sliding floor 16 extends.

The arranged in the treatment tank 1 above the sliding floor 16 transport path 15 has a Trans ^¬ port tube 21, the basic structure is seen in particular in Figure 4. Starting from a short straight pipe section 21a with a constant square or rectangular cross section, which is connected to the Transportdüsenanord ^¬ tion 14, the transport tube 21 in a long section 21b a conical widening of the flow channel formed by the transport tube, the cross-sectional shape is accordingly increasingly rectangular , At the the Is transport nozzle assembly 14 remote from the end of the transport ^¬ pipe portion 21b, a right ^¬ in cross-section rectangular rope outlet bend 22 connects, which extends over approximately 90 ° and in the region of its side walls and at ^¬ least its radially outer wall with a perforation 23 is formed. It opens in the manner shown in Figure 2 manner in the sliding floor 16 on the Warenstrangein- running side 18th

The goods strand 17 is thereby treaded on the Warenstrangein- running side across the width of the trough-shaped sliding floor 16, which is given the Warenstrangauslaufbogen 22 via the transport tube 21 a reciprocating uniform motion. For this purpose, the transport ^¬ pipe is pivotally mounted together with the transport nozzle assembly 14 about a rotation axis 24 (Figure 2), which extends through a straight pipe socket 25 a unspecified pump, a heat exchanger and a lint filter containing transport supply line 26 to the transport nozzle assembly 14 , The pipe stub 25 is rotatably mounted rotatably at 27 in a mounted on the treatment tank 1 pivot bearing.

The reciprocating pivoting movement is the

Transport tube 21 issued by a patch on the treatment tank 1 drive motor 28 (Figure 2), which is coupled via a lever mechanism 29, such that the transport tube 21 is moved at a uniform speed over its pivoting range back and forth.

The long-storage machine so far described as an example of a device according to the invention is illustrated in its De ^¬ tails in DE 10 2013 110 492 B4. It should be mentioned that the erfindungsge ^¬ Permitted device is by no means restricted to training as a long memory machine. It can be used to the same extent in machines with different designs, for example so-called short-storage machines, for which reference should be made, for example, to EP 1 722 023 A2. Even devices with non-pressurized treatment container, which may optionally be square, are within the scope of the invention.

The transport path 15 is connected to the pipe section 21a having a constant cross-section over its length, to a transport nozzle 30 of the transport nozzle arrangement 14, the exact construction of which is apparent in particular from FIGS. 3 to 11:

On the tube section 21a a cylindrical housing ^¬ sebodenplatte 34 is placed sealed, which is bolted to an annular flange 35 and forms together with this so ^¬ as a cylindrical side wall 36 and connected to this cylindrical cover plate 37 a medium-tight drum-shaped unitary nozzle housing 38. ^{Seit ¬} lich next to the pipe section 21a in the bottom plate 34, an inlet port 39 for a transport medium, here the treatment liquid, is provided, which can flow into the nozzle housing 38 via a Rohrbo ^¬ conditions 40 of Behandlungsflüssigkeitszuführleitung 26 (Figure 2).

Coaxially to the nozzle outlet opening 42 for the continuous flow of goods bounded by the pipe section 21a, a fabric strand inlet opening 43 is formed in the opposite cover plate 37 of the nozzle housing 38, through which the product strand 17 enters the nozzle housing 38 during operation. In the illustrated embodiment, the nozzle inlet port 43 is formed rectangular with approximately horizontally extending longer sides. However, both nozzle openings 42, 43 can have any shape that is expedient for the respective application, they can be square, polygonal, circular, oval, etc., designed. Also, it is not absolutely necessary that the two nozzle openings 42, 43 have the same shape of their boundary. In differently edged nozzle openings in the nozzle housing 38, a corresponding transition region is present.

A the Düseneinlass- opening is externally fitted 43 encloses rectangular frame 44 on the cover plate 37, the frame legs which form such as in particular out of the Fi ^¬ guren 3 to remove 5, have a substantially semi-cylindrical shape and guide elements for a ^¬ running rope and at the same time can influence the flow conditions of the transport medium.

At an axial distance in front of the nozzle inlet opening 43, an approximately part-cylindrical guide plate 450 is arranged transversely in the treatment tank 1. On ^¬ administration of the baffle 450 is 17 securely initiate the strand outlet side on the goods 20 raised from the slide base 16 fabric rope into the nozzle inlet aperture 43rd In principle, it is also conceivable, instead of the guide plate 450 to provide a direct ver ^¬-bound with the nozzle housing 38, funnel-shaped rope inlet arc 450a, as this is at 450a ^¬ indicated as an alternative in FIG. 2 In the nozzle housing 38 are two annular CLOSED ^¬ sene, the contour of the nozzle inlet opening 43 adapted frame-menförmige nozzle elements 45, arranged in alignment with adjustable nozzle 46 with the inlet opening 43 and the nozzle outlet port 42nd Each of the nozzle elements 45, 46 carries on its outer side two diametrically opposite Flan ^¬ cal 47 and 48, which are mounted on each side of the nozzle openings via associated aligned bearing bores on a rod 49 slidably. The two parallel zuei ^¬ aligned and opposing rods 49 are performed sealed by the bottom plate 34 of the nozzle housing 38 and mounted relative to the bottom plate 34 axially displaceable at this. Each of the bars

49 has a portion lying in the nozzle housing 38

50 smaller diameter, which is bounded on one side by an annular shoulder 51 (Figure 11) and on the other side by a screwed onto a corresponding threaded portion 52 on ^¬ nut 53. Between the two flanges 47, 48 spring means in the form of pushed onto the section 50 compression springs 54 are provided, which endeavor, the two flanges 47, 48 and thus the Dü ^¬ senelemente 45, 46 in the axial direction away from each other to Drü ^¬ bridges.

On their protruding from the nozzle housing 38 side of the two rods are ersehenden at 540 slit (Figure 8) and through a particular, in FIG 6 49 acting as a lever mechanism 55 lever mechanism together bezüg ^¬ Lich the bottom plate 34 of the nozzle housing 38 adjustable. The lever mechanism 55 is part of control means, which he ^¬ arbors to adjust the nozzle members 45, 46 either individually or jointly axially ge ^¬ as yet ER in detail will be purified. The lever mechanism 55 comprises two L-conveyor-shaped operating lever 56, which are gela ^¬ Gert at 57 about a common horizontal axis on the nozzle housing 38 and one leg of which is articulated on a lug 58 with the associated rod 49, while the other leg is pivotally coupled to a common U-shaped actuator bracket 59. The ^{Betätigungsbü ¬} gel 59 is connected to an indicated at 60 actuating rod, which is led out sealed from the treatment tank 1 and allows, by a servo motor not shown or other appropriate actuating means, the nozzle elements 45, 46 from the outside to verstel ^¬ len.

The two nozzle elements 45, 46 define, depending on their respective position, between themselves and / or the cover plate 37 or the bottom plate 34 of the nozzle housing 38 nozzle gaps, which can be opened or closed independently of one another or adjusted in their nozzle width, for which purpose in detail Referring to Figures 8 to 11:

The nozzle element 45 is formed on its side facing the nozzle inlet opening 43 with a rounded edge 60 (FIGS. 6, 8) which cooperates with an associated seat 61 provided in the cover plate 37 and can define a first nozzle gap 62 therewith (FIG ,8th) . The seat 61 is formed at a pre in the cover plate 37 ^¬ provided for annular recess 63, which lies on the inside boundary is indicated at 170 fabric rope transport direction curved pointing at 61a, so that with an open gap 62 a at ^¬ play, in FIG 8 at 64 indicated gap flow with a strong acting in the product strand transport direction 170 component stops.

On the rounded edge 60 opposite the end face the nozzle member 45 is provided at 65 with a ge ^¬ curved chamfer, the tapered portion points in the goods strand transport direction 170. With this beveled part 65 a directed to a corresponding opposite chamfer can cooperate 66 provided ^¬ edge portion of the other nozzle element 46 to form a second die gap 67 (Figure 10). The arrangement is made in such a way that when the nozzle gap 67 is open, a gap flow indicated at 68 results, which has a strong component acting in the product strand transport direction 170.

At its opposite end face of the nozzle member 46 is rounded edge 69 formed (Fi gur ^¬ 10, 11). It is associated with a provided in the bottom plate 34 seat 70, which contains a seal indicated at 71. When lifted from the seat 70 nozzle member 46, a third nozzle gap 72 (Figure 11) is limited between the edge 69 and the seat 70. In this case, the seat 70 is oriented in an annular recess 73 of the bottom plate 34 with an adjoining the nozzle outlet opening 42, counter to the fabric rope transport direction 170 highly curved lip 74 (Figure 11) designed such that with an open nozzle gap 72 a indicated at 75 Spaltströ ^¬ mung shows that has a strong counter to Warenstrangtrans ^¬ port direction 170 directed component.

The operation of the above described Transport nozzle assembly 14 is illustrated in Figures 8 to 11:

The two rods 49 are pulled out of the nozzle housing 38 as shown in FIG. Thus, the nozzle member 45 is in a position maxima ^¬ ler opening of the first nozzle gap 62. The gap flow 64 is dominant for the characteristics of the transport nozzle. The product strand is subjected to a high volume flow of the transport medium. The nozzle pressure is comparatively ^¬ low. The second and third nozzle gaps 67 and 72 are closed. By the compression springs 54, the other nozzle member 46 is pressed against its seat 70 with great force.

In the example shown in Figure 9 operating state, the two rods 49 are turned so far ^¬ inserted in the nozzle housing 38 that the first die slot 62 and the strand conveying direction in goods 170 following second nozzle gap 67, which lies between the two nozzle members 45 46 are opened, are. The die width can ^¬ example, in two nozzle columns 62, 67 be 2 mm. The fabric strand is now moved forward with two forward jets in the product strand transport direction 170, as indicated by the slit flows 64a, 66a in FIG. The third nozzle gap 72 is closed.

However, the rods 49 can also be pushed so far into the nozzle housing 38 that results in the situation shown in Figure 10, in which only the existing between the two nozzle elements 45, 46 second nozzle gap 67 is opened. In this setting, only a narrow nozzle gap is open. It will be comparatively reached high strand speeds. The first nozzle gap 62 and the third nozzle gap 72 are closed.

In the example shown in Figure 11 operating state, the two rods 49 are further into the nozzle housing 38 is ^¬ pushed namely so far that the first nozzle gap 62 Zvi ^¬ rule the nozzle member 45 and the fixed to the housing top plate 37 and the second die gap 67 between the two nozzle members 45, 46 are closed. The third nozzle gap 72, between the nozzle member 46 and the part of the Dü ^¬ sengehäuses 38 forming bottom plate 34 is open. In this setting, the nozzle elements 45, 46, a direction indicated by the gap flow 75 backward beam of the transport medium is generated. The goods strand is therefore transported backwards.

The transport ^¬ medium used to drive the strand of goods can be both liquid and gaseous. It may also be a gas stream laden with liquid droplets.

The cross section of the transport system of Transportdü ^¬ senanordnung 14 and the transport path 15 may be formed both round and square or have any other ^meaningful full ^¬ form.

The nozzle elements 45, 46, including the parts of the lever mechanism 55 for initiating the adjustment and Betä ^¬ ment forces for the nozzle elements are constructed so that they can be produced from precision casting. This results in additional significant reductions of Herstellkos ^¬ th. Also, the bottom plate 34 of the nozzle housing 38 is constructed so that they can also be produced from investment casting is. This also results in cost reductions of material and manufacturing costs. The cover plate 37 and the subsequent ran as ^¬ side wall 36 of the nozzle housing 38 can optionally including the guide elements 44, special ^¬ DERS be advantageously manufactured as a deep-drawn sheet metal part, also with low material and manufacturing costs.

An example of this embodiment is shown in FIG. 12:

The deep-drawn housing part is at 38a illustrated ^¬ light. It has a flat base 340, with which it is screwed to the base plate 34 via screws indicated at 341. On the opposite side, the housing part 38a at 44a the Warenstrangeinlassöffnung 43 bounding beaded retracted inward. The bead-like portion 44a has an approximately semicircular cross-sectional shape and delimited ^¬ with its pointed edge together with its adjacent nozzle member 45 of the first die slot 62, as can be seen from FIG 12th In this case, the bead-like part acts 44a not only as a guiding element for the voltage in the Warenstrangeinlassöff- 43 incoming rope, but at the same time causes a significant improvement in the flow ^¬ relationships by helping to prevent unwanted eddies in the transport medium current and We ^¬ causes significant laminar flow conditions. The Wa ^¬ renstrangeinlassöffnung 43, as in the embodiments described above, rectangular, square and / or otherwise designed appropriately. The A ^¬ sake of simplicity illustrated only the nozzle member 45 in the figure 12th In a further modified embodiment shown in FIGS. 13 to 16 in a representation similar to FIGS. 6 and 10 to 12, the same parts are designated by the same reference numerals with the abovementioned figures and are not explained again.

The portion 50 of smaller diameter of the rods 49 is formed in this embodiment on a bolt 53 a, which is screwed into the respective rod 49. In addition, the lever mechanism 55a, which forms part of Steuermit ^¬ stuffs designed somewhat differently with the operating levers 56a, however, the common U-shaped operating bracket 59 (Figure 14) with the indicated at 60 operating rod it also allowed in this case, by ei ^¬ ner not shown actuator or other appropriate actuating means to adjust the nozzle elements 45, 46 from the outside.

Apart from these rather minor constructional changes compared to the embodiment of the transport nozzle illustrated with reference to FIGS. 6 to 11, the two annularly closed nozzle elements 45, 46 enclosing the product strand, not shown in the figures, are designed in such a manner that in the embodiment according to FIGS to 11 between the two nozzle elements 45, 46 selectively adjustable nozzle gap 67 deleted. On the one nozzle member 45 is rather on its side facing the other nozzle member 46 inside an all-round smooth-walled skirt 450 formed on ^¬ axially projecting overlaps the other nozzle member 46 on the inside, as can be seen for example from Figure 16. On the other nozzle member 46 is a circumferentially running in a corresponding circumferential groove endless sealing ring 451 provided which bears against the skirt 450 under bias outside. This is between the two sealing elements 45, 46 an axially movable sealing ^¬ place available, which prevents the passage of transport medium and at the same time allows a mutual axial movement ^{¬ movement of} the two sealing element against each other.

The operation of this modified Transportdü ^¬ senanordnung is illustrated in Figures 14 to 16:

In the operating state according to FIG 14, the two rods are pulled ^¬ up to the stop of the nozzle body 38 out 49th Thus, the nozzle member 45 is in a position of maximum opening of the first nozzle gap 62, thus resulting in an operating state similar to Figure 8. By the compression springs 54, the other nozzle member 46 is pressed with gro ^¬ ßer force against its seat 70, so that the otherwise existing there nozzle gap 72 is closed. The gap width indicated at 64 promotes the continuous flow of goods in the transport direction 170. The gap width of the first nozzle gap 62 can be adjusted by appropriate adjustment of the nozzle element 45 by means of the rod 49 arbitrarily purpose ^¬ , without thereby by the other, by the springs 54 Fixed against the seat 70 pressed-nozzle member 46 limited nozzle gap 72 geöff ^¬ net would.

In the example shown in Figure 15 operating state, the two rods 49 are further into the nozzle housing 38 is ^¬ pushed namely so far that the first nozzle gap 62 Zvi ^¬ rule the nozzle member 45 and the fixed to the housing top plate 37 and the other nozzle gap 72 between the nozzle member 46 and forming in a part of the nozzle housing 38 Bo ^¬ denplatte 34 are closed. The two nozzle elements 45, 46, which are pressed liquid-tight against each other in their maximum axial distance from each other, are sealed against each other by the seal formed by the skirt 450 and the anlie ^¬ ing sealing ring 451 so that no transport medium can pass between them ,

In this operating position, the drive current of the transport nozzle is thus completely switched off. The transport ^¬ nozzle takes over the function of an otherwise required from ^¬-off valve in the supply line 26 of the transport Medi ^¬ umsstrom leading pipe portion. The nozzle gap 67 present between the movable nozzle elements 45, 46 in the embodiment according to FIGS. 8 to 12 is closed by the skirt 450 and the sealing ring 451. By eliminating the otherwise necessary shut-off valve, the structure of the entire goods strand transport system can be executed significantly kos ^¬ tengünstiger.

In Figure 16, finally, an operating state is Darge ^¬ provides, corresponding to the operation state after FIG. 11 The two rods 49 are pushed to the stop on the cover plate 37 in the nozzle housing 38, whereby the first nozzle gap 62 between the nozzle member 45 and the cover plate 37 is closed. The other nozzle gap 72 between the nozzle member 46 and the part of the nozzle housing 38 forming bottom plate 34 is open. In the ^¬ water setting of the nozzle elements 45, 46, a direction indicated by the gap flow 75 backward beam of the transport medium is generated. The thread is therefore transported backwards. A transport medium passage Zvi ^¬ rule the two nozzle members 45, 46 is carried by the skirt 450 and prevents the sealing ring 451 sealing point formed.

Finally, it should be mentioned that the lever mechanism 55 containing mechanism with the rods 49 single ^¬ lich a particularly convenient and simple Ausführungs ^¬ example of the adjustment mechanism of the two Düsenele ^¬ elements 45, 46 represents. For those skilled in the art, other equally effective adjustment mechanisms for the nozzle elements 45, 46 are such that they can assume the operating positions explained with reference to FIGS. 8 to 11 and 14 to 16. The described lever arrangement of the Hebelge ^¬ drive 55 for adjusting the nozzle elements 45, 46 is particularly ^¬ cost. About the operating rod 60 can be driven by a ^¬ for example, digital control element, which consists of a spring-loaded Pneumatikbalg For example, the above pulse valves with a

Pressure medium is applied.

The number of nozzle elements is not limited to the two nozzle elements 45, 46 selected in the exemplary embodiments. It can also be provided more than two, for example, three nozzle elements, between which then a correspondingly larger number of selectively openable nozzle columns are formed similar to the nozzle gap 67. In addition, embodiments are also conceivable in which only one nozzle element is present, which allows the operating states of Figure 8 and Figure 11 to be set optionally. The column of nozzles themselves are preferably stu ^¬ nitely adjustable, but is dependent on the operating conditions, a gradual adjustment is possible. The Nozzle gap width can be set individually, which is generally true for all embodiments of the nozzle assembly, but also embodiments are conceivable in which the gap widths of individual nozzle gaps are controlled in mutual dependence. Finally it should be mentioned that the nozzle column as enclosing the rope of the above-described embodiments, ^an annular ^combustion column are formed so that a continuous ring in the circumferential direction flow results as a gap flow. Also possible are embodiments in which the gap flow is discontinuous in the circumferential direction, ie consists of individual spaced-apart transport beams that act on the continuous strand of goods.

In a device for the treatment of rope-shaped textile goods in the form of a circulating strand of goods, which is circulated during at least part of its treatment, a transport nozzle assembly 14 is provided for the strand of goods having a transport nozzle 30 with a nozzle housing 38, in which at least two nozzle gaps are limited for the transport medium. Of the nozzle columns at least one nozzle gap 62 for conveying the durchlau ^¬ fenden product strand in the transport direction 170 and at least one nozzle gap 72 for conveying the continuous strand of goods in a direction opposite to the direction of transport direction is set up.
