Abstract
A plant for spinning multi-coloured threads comprises a plurality of extruders (10, 12, 14; 101; 102, 103) and a spinning beam (16) with spinning nozzle packs or spinnerets (D1 through D18; 8) which each generate a creel thread.
The creel threads can be combined in groups in processing positions P1 through P6, or according to the Figures 6 through 9 can be combined for forming multi-coloured threads. An exchangeable or rotatable distributor element (Fig. 2b, Figures 3 and 4; Figures 6 through 12.2) is provided at a connecting point (VSt) for connecting ducts for melted material from the extruders to ducts for melted material to the spinning nozzle packs or spinnerets (P1 through P6; 8). The plant configuration can be changed by exchanging the distributor element e.g. in such a manner that at least in one group all threadsshow the same colour.

08.07.1998 RWr/sr-2719 Synthetic Thread Spinning Plant The present invention concerns a plant for spinning synthetic threads, in par-ticular for distributing melted material from a plurality of extruders to the vari-ous spinning points (spinning nozzle packs or spinnerets) of a so-called spin-ning beam.
State of the art Plants for spinning synthetic threads from melted material have been shown and described in DE-A-33 43 714 (= CH-B-657 633). Spinning beams for plants of this type can be found in the CH-B-655 520 or in the US-B-5'059'104.
In most plants the melted material is distributed by an extruder as evenly as possible to a large number of spinning points (spinning nozzle packs or spin-nerets) co-ordinated to the extruder. The filaments spun in the nozzle packs must be drawn after cooling (solidifying), possibly texturized and wound into a thread package. A draw winding machine is described e.g. in the EP-A-532 464.
Interest is growing, however, in the manufacture of multicolour threads, e.g.
according to EP-A-784 109 and/or EP-A-434 601. A method of this type re-quires a plurality of extruders which via suitable ducts for melted material areto be connected to the respective spinning points. Examples of a plant of this type can be found in the EP-A-350 450and the US-B-5'595'699. Further expla-nations can be found in the journal Chemiefasern/Textilindustrie (Synthetic Fibres/Textile Industries), October 1985, pages 668 and 672.
The task of distributing the melted material as such can be solved using con-ventional distributing means. The plant in this case becomes "dedicated" to the manufacture of multicoloured threads which is not always desirable to the plant owner. Thus there is the task, or the wish rather, hat a plant of the typementioned can be laid out flexible for producing different thread types CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 (multicolour or monochrome). A plant of such type has been mentioned in the article in Chemiefasern/Textlindustrie (Synthetic Fibres/Textile Industry) citedabove but no indications were given for solving the configuration problems.
The task could be fulfilled using valves. A solution of that type, however, results in the disadvantage that in at least one configuration "dead" (unused) ducts for melted material would be created.
The present invention thus provides a new distributor for melted material ap-plied in a plant for spinning synthetic threads. This distributor is conceived for connecting two or more sources of melted material with a greater number of sinks of melted material. The distributor correspondingly comprises at least two inlets for melted material to be connected each with a source of melted material and a greater number of outlets for melted material to be connected each to a sink for melted material. The inlets are connected via ducts to pre-determined outlets in such a manner that the melted material entering each inlet is transferred to the outlets co-ordinated to the respective inlet. The dis-tributor can be provided for a predetermined configuration of the inlets, outlets and connecting ducts in which arrangement the ducts of the plant must be ar-ranged correspondingly. The distributor, however, is laid out as an exchange-able element. The plant configuration thus can be changed by exchanging the distributor, provided that all distributors are provided with the suitable arrange-ment of the inlets, and of the outlets respectively.
The present invention of course also concerns a corresponding plant provided with the arrangement required of the ducts for the melted material. The sources of melted material normally will comprise one extruder each. The sinks of melted material normally will comprise devices forming filament, or processing filament respectively. The devices processing filaments can be "multi-thread" processing devices (processing a plurality of threads each).

08. 07.1 998 RWr/sr-271 9 Embodiments according to the present invention are explained in more detail in the following in the sense of examples with reference to the illustrated Fig-ures. All illustrations shown are of schematic nature merely. It is shown in the:
~ig. 1 a plant with three extruders and eighteen spinning nozle packs or spinnerets, ~ig. 2 the arrangement of the duct mouths in the Fig. 2A and in the Fig.
2B at a predetermined connecting point in the plant according to the Fig. 1, ~ig. 3 the arrangement of the distributing ducts in a first distributor for es-tablishing a first configuration of the plant according to the Figures 1 and 2, ~ig. 4 the arrangement of the distributing ducts in a second distributor for establishing a second configuration of the same plant, and in the ~ig. 5 a side view of a single connecting duct in a distributor according to the Fig. 3, ~ig. 6 a plant with three extruders, six spinning pumps and twelve spinning nozzle packs or spinnerets, shown schematically, ~ig. 7, 8, and 9 a variant each of the plant according to the Fig. 6, shown schematically, ~ig. 10.1 through 10.4 an element each according to the Figures 8 and 9, shown in half-schematic manner and in more detail, ~ig. 11.1 through 11.4 a variant of the element each according to the Figures 10.1 through 10.4, ~ig. 12.1 the element according to the Fig. 10.1 with further details, shown in half-schematic manner as seen in a cross-section in the direction Vl according to the Fig. 12.2, CA 022~60~0 1998-12-1~
08.07.1998 RWr/sr-2719 ~ig. 12.2 the element according to the Fig. 12.1 seen in the direction V ac-cording to the Fig 12.1, shown partially simplified.
The plant according to the Fig. 1 comprises three extruders 10, 12, and 14 re-spectively, and a spinning beam 16 with spinning nozzle packs or spinnerets D1 through D18, e.g. according to WO 95/07378 and/or WO 95/00684. The extruders normally will be arranged on an upper floor and the spinning beam on a floor below. The extruders 10, 12 and 14 supply melted material of one colour each, e.g. red (R), blue (B) and yellow (G). In each spinning nozzle pack D1 through D18 a monochrome "creel thread" each is to be spun. In most cases these are multi-filament threads, the present invention, however, not being restricted to an application of this type. The colours chosen as such are of no consequence within the scope of the present invention, but the terms red (R), blue (B) and yellow (G) for the colours are also applied in the furtherexplanations in the sense of examples. The ducts for the melted material are not visible in the Fig. 1, as they are covered by heat insulating material - butthey lead into the spinning beam 16 where the melted material is to be distributed to the spinning nozzle packs or spinnerets as will be explained in the following.
Processing of the creel threads spun depends on the current production pro-gramme of the plant. In any case it must be possible to combine the creel threads into a multicoloured thread, e.g. according to EP A - 784109. For this purpose the spinning nozle packs or spinnerets are arranged in groups of three, P1 through P6, each of which is to comprise a red, a blue and a yellow creel thread. To each group also suitable processing means are co-ordinated in such a manner that a multicoloured thread can be formed from the creel threads of the respective group. As this processing manner is not of impor-tance within the scope of the present invention a further description or expla-nation is dispensed with. But the processing means are subdivided into "posi-tions" in such a manner that a "position" of one of the groups P1 through P6 is CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 co-ordinated to the spinning nozzle packs or spinnerets D1 through D18 and can process the threads supplied by the spinning nozzle packs or spinnerets of the co-ordinated group.
It should be possible also e.g. to change the plant configuration in such a manner that all spinning nozzle packs or spinnerets, or at least one group, produce monochrome (creel) threads, i.e. in this case it is undesirable to gen-erate a multicoloured thread in at least one of the groups. In other words, the configuration of the plant (in particular of the distribution ducts) should be flexible enough that the thread variety produced can be adapted to the current production programme. The processing devices of course also must be adaptable correspondingly which herein is not described in more detail as the present invention does not concern the further processing of the threads spun.
The present invention concerns the distribution of the melted material to the spinning nozzle packs or spinnerets in a flexible plant of this type.
It now is assumed that for each extruder a supply line and for each spinning nozzle pack or spinneret an individual feed line is provided. The supply lines extend from the respective extruder to a connecting or distributing point VSt inthe spinning beam 16 and the feed lines each extend from the same point VS
to the respective spinning nozle packs or spinnerets. At this point VS the mouths of the supply lines in a given arrangement (e.g. according to the Fig.
2A) are arranged side by side whereas the mouths of the feed lines also are arranged in a predetermined arrangement (e.g. according to the Fig. 2B).
These mouths are to be interconnected by means of an exchangeable con-necting means to be described in the following, in which arrangement the plant configuration can be changed by exchanging the connecting means.
The optimum arrangement of the mouths in a given plant depends on the lay-out of the plant. The arrangement shown has been chosen for the sake of sim-plicity merely and thus is to be understood in the sense of an example only. In CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 this arrangement the mouths of the feed lines are arranged in groups of three (Fig. 2B) in which arrangement these groups of mouths correspond to the groups P1 through P6 according to the Fig. 1 and form a horizontal "line" each Z1 through Z6. The mouths of the line Z1 thus are co-ordinated to the spinning nozzle packs D16 through D18. The six lines together form three vertical "columns" as the mouths of the uppermost line Z1 are arranged vertically above the corresponding mouths of the other lines. The mouths of the supply lines also form a horizontal "line" (Fig. 2A) which supply red (mouthR), blue (mouth B) and yellow (mouth G) melted material after the plant has started operation.
The base principle of the connection is explained first with reference to the Figures 3 and 4. In the Fig. 3 the mouths of the feed lines are shown again in which arrangement also three vertical connecting ducts KR1, KB1, KG1 are indicated schematically. These three ducts are co-ordinated to a supply mouth each (R, B, G, Fig. 2A) also and they co-ordinate the columns to the respective supply mouths. For this purpose the ducts KR1, KB1 and KG1 each are provided with a connecting flange SR1, SB1, SG1 which connects the duct with the mouth R, B, G. The ducts KR1, KB1, KG1 also are provided with six flanges SV which connect each duct with the mouths of the column (Fig. 2B) co-ordinated to it. In this configuration each group of spinning nozles or spin-nerets P1 through P6 is supplied with red, blue and yellow melted material and the corresponding filaments (creel threads) can be processed into a multicoloured thread.
In the Fig. 4 the mouths of the supply lines are shown in the unchanged ar-rangement but in combination with a changed distributor (compared to the one shown in the Fig. 3) which shows a changed arrangement of the ducts and of the connecting flanges. Again three connecting flanges SR2, SB2, SG2 are provided via which melted material is conveyed from the mouths R, B, G (Fig.
.

08.07. 1 998 RWr/sr-271 9 2A) to one of the three ducts each KR2, KB2, KG2 as will be discussed in the following:
In this example the following overall arrangement is desired (R = red, B = blue and G = yellow):
Line Position Nozle packs Creel threads Final product Z1 P1 D1, D2, D3 R, R, R three red threads Z2 P2 D4, D5, D6 B, B, B three blue threads Z3 P3 D7, D8, D9 R, B, G multicoloured thread Z4 P4 D10, D11, D12 R, B, G multicolouredthread Z5 P5 D13, D14, D15 R, B, G multicoloured thread Z6 P6 D16, D17, D18 G, G, G threeyellowthreads Each duct KR2, KB2, KG2 thus comprises a vertical leg KR2S, KB2S, KG2S
and a horizontal leg KR2W, KB2W, KG2W. The horizontal leg KR2W is con-nected via the connecting flanges VS with all the mouths of the line Z1, the horizontal leg KB2W with all the mouths of the line Z2, and the horizontal leg KG2W with all the mouths of the line Z6. The vertical leg KR2S via the corre-sponding connecting flanges is connected with the "further" mouths of the left side column, the vertical leg KB2S with the further mouths of the middle col-umn, and the vertical leg KG2S with the further mouths of the right side col-umn.
There are, of course, a great number of possibilities of establishing the re-quired connections. In the preferred variant exchangeable connecting means are prepared in such a manner that by exchanging the connecting means cur-rently in use the plant configuration can be changed.
In the Fig. 5 a connecting element is shown which could be applied in an ex-changeable means for establishing the arrangement according to the Fig. 3.
CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 This connecting element comprises the connecting flanges SR1 (Fig. 3), the duct KR1 (Fig. 3) and six connecting flanges SV1 through SV6 for connecting the connecting element with the mouths of the left side column according to the Fig. 3. Each of the flanges SR1, and SV1 through SV6 respectively, is pro-vided with a coupling means KM (indicated schematically merely) for coupling it to corresponding coupling means on the supply line, or on the feed lines re-spectively. The exchangeable connecting means in this variant comprises three connecting elements of this type which each are co-ordinated to one of the mouths R, B, G (Fig. 2A). The three connecting elements can combined into a connecting device by means of a suitable holder (not shown) which, however, is not mandatory.
Similar (but more complicated) connecting elements could be designed for establishing the connection according to the Fig. 4.
The connections preferentially are established by applying an exchangeable element (e.g. a plate or a pack of plates). The mouths (Figures 2A and 2B) could be provided e.g. in end plates and the distributor element (the distributor plate) could be attached in between (using suitable sealing elements). In an example the connecting element comprises a distributor pack consisting of two plates pressed against each other. The connecting flanges extend through the thickness of one of the plates, the flanges SR, SB, SG extend through the thickness of the other plate. The ducts KR, KB, KG are provided in the surface of one plate facing the other plate e.g. in the form of grooves. Of course the grooves could be provided also in both plates.
In the Fig. 6 three extruders are shown designated with the reference numbers 101, 102 and 103 in which arrangement each of the extruders supplies a dif-ferent melted material. In this arrangement the differences in the melted mate-rials could concern the colour (e.g. B = blue, G = yellow, R =red) or other characteristics of quality or appearance.
CA 022~60~0 1998-12-1~
08. 07. 1998 RWr/sr-271 9 From each extruder 101, 102, 103 a supply duct for melted material each de-signated 4.1, 4.2 and 4.3 extends separately into a distributor 5 for melted material.
Via this distributor 5 the melted material from the extruder 101 is distributed via intermediate tubes for melted material 6.1, from the extruder 102 via the intermediate tubes for melted material 6.2 and from the extruder 103 via intermediate tubes for melted material 6.3 each into spinning pumps 7 and subsequently to the spinning nozzle packs or spinnerets 8. From this it can be seen that four spinning nozle packs or spinnerets arranged side by side each are supplied with the same melted material.
The distributor 5 for melted material shown in the Fig. 6.1 in more detail is pro-vided with three distributor plates for melted material which are superimposed and held together and stationary by elements not shown.
In this arrangement the melted material from the extruder 101 is guided via the intermediate tubes 6.1 for the melted material and via the upper distributor plate 51, the melted material from the extruder 102 via the intermediate tubes 6.2 and via the middle distributor plate 52, and the melted material from the extruder 103 via the intermediate tubes 6.3 and via the lower distributor plate 53.
In this arrangement distribution of the intermediate tubes 6.1 is provided in one longitudinal direction of the rectangular distributor for melted material, whereas distribution of the intermediate tubes 6.2 is provided in another longitudinal direction, and distribution of the intermediate tubes 6.3 is provided in a further longitudinal direction of the rectangular distributor for melted material, whereas the supply tubes for melted material 4.1, 4.2 and 4.3 are provided in the fourth longitudinal direction of the distributor 5 for melted material, i.e. a spinning nozzle pack or spinneret 7 is supplied three times with the same melted material which using the connecting tubes 38, 39 and 40 are CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 supplied to the corresponding spinning pumps 7. I.e. that in this arrangement the tubes 38 conduct e.g. the melted material B, the tubes 39 e.g. the melted material G and the tubes 40 e.g. the melted material R.
In the Fig. 7 the same extruders 101, 102 and 103 are shown with e.g. the same distribution of melted material per extruder as indicated in the Fig. 6 andalso the same supply tubes for melted material 4.1, 4.2 and 4.3 which conduct the melted material to the distributor for melted material designated 5.1 here.
The arrangement of the intermediate tubes for the melted material 6.1, 6.2 and 6.3 here differs from the one shown in the Fig. 6.
The difference is seen in that a spinning nozle pack or spinneret is supplied with each melted material, i.e. in the present case three different kinds of melted materials, namely the types of melted material B, G and R. Accordingly the intermediate tubes for melted material 6.1, 6.2 and 6.3 extend from each of the above mentioned longitudinal directions of the distributor for melted mate-rial away towards the spinning pumps 7.
The advantage of these superimposed distributor plates is seen in that that, firstly, the whole system of connecting tubes between the distributor 5, or 5.1 respectively, for melted material and the spinning pumps 7 can be maintained unchanged if the supply of melted material is changed, and that, secondly, in the corresponding plates all ducts can be provided adapted to the distribution according to the distributor 5, or 5.1 respectively, for melted material, i.e. that if the distribution of the melted material is to be changed, the flows of meltedmaterial can be deviated e.g. by placing inserts (not shown) in the horizontal ducts of the individual plates 51, 52, 53, or 51.1, 52.1, 53.1 respectively.
If these ducts in the distributor plates, extending in the directions of the sur-faces, each are carved into the surface of each plate, a fourth plate 36 is pro-vided, indicated with dash-dotted lines, in such a manner that the ducts carved into the uppermost plate 51.1, or 52.1, or 53.1 respectively, can be covered.
CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-2719 -11 -In the Fig. 8 instead of the distributor 5 a slide plate 116 of a distributor slide for melted material 37 (Figures 10.1 through 10.4), or 37.1 (Figures 1 1.1 through 11.4) is shown which will be explained in more detail in the following with reference to further Figures.
The slide 37 in this arrangement, as shown schematically, is provided, for each type of melted material from the extruders 101, 102 and 103, with a distributor duct 109, and 110 and 111 respectively, into which a supply duct for melted material each merges, e.g. the melted material from the extruder 101 via the supply tube 4.1 for melted material into the duct 109, the melted material from the extruder 102 via the distributor tube 4.2 into the duct 110 and the melted material from the extruder 103 via the distributor tube 4.3 into the duct 111. In this arrangement each of the ducts is connected with three outlets for melted material to which the connecting tubes 38, and 39 and 40 respectively, are connected.
In the example according to the Fig. 8 the melted material is distributed via the connecting tubes 38 to two group spinning pumps 7 and from there to four spinning nozzle packs or spinnerets 8. The same distribution mode is provided for the melted material from the extruder 102 via the connecting tubes 39, and for the melted material from the extruder 103 via the connecting tubes 40.
The ducts 109, 110 and 11 1 are laid out, as to be described later, in the slideplate 16 in such a manner that the position of the ducts 109, 110 and 1 11 can be brought into a position shown in the Fig. 9 if the plate is shifted, or rotated respectively, by 90~.
In the arrangement according to the Fig. 8 the distribution of the melted mate-rial corresponds to the one according to the Fig. 6 and the distribution of the melted material shown in the Fig. 9 corresponds to the one shown in the Fig.
CA 022~60~0 1998-12-1~
08. 07.1 998 RWr/sr-271 9 7, i.e. each spinning nozzle pack or spinneret 8 is supplied with all three types of melted material B, G and R.
In the Figures 10.1 through 10.4 the distributor slide 37 for melted material mentioned earlier is shown.
In the Fig. 10.1 the above mentioned distributor slide 37 is shown with an up-per plate 15, a lower plate 17 and the slide plate 1 16 arranged in between.
The supply distributing tubes 4.1, 4.2 and 4.3 merge into the upper plate 15 and to the lower plate 17 the connecting tubes 38, 39 and 40 are connected.
In the Fig. 10.2 a cross-section is shown of the slide plate 116 along the linesl-l shown in the Fig. 10.1, from which the ducts 109, 110 and 111 mentioned earlier can be seen.
From the Figures 10.1 and 10.2 it can be seen that the supply tube 4.1 for melted material merges into the duct 109, the tube 4.2 merges into the duct 110 and the tube 4.3 merges into the duct 111 each via the upper plate 15.
The connecting tubes 38 merge threefold through the lower plate 17 namely from below, as seen in the viewing direction of the Fig. 10.1, into the duct 109, whereas the connecting tubes 39 merge via the lower plate 17 into the duct 110 and the connecting tubes 40 merge via the lower plate 17 into the duct 111.
In a later Figure it will be shown that the upper plate 15 and the lower plate 17 are arranged stationary whereas the slide plate 116 can be shifted, or rotated respectively, relative to the stationary plates by 90~, namely about the axis ofthe supply tube for melted material 4.2.
This state of the slide plate 116 rotated by 90~ is shown in the Figures 10.3 and 10.4.
-CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-27 19 -1 3-From this arrangement it can be seen that the positions of the supply tubes for melted material 4.1, 4.2 and 4.3 as well as the positions of the connecting tubes 38, 39 and 40 are the same and that the duct 109 is supplied from the supply tube 4.1 with melted material, that the duct 110 is supplied from the supply tube 4.2 with melted material and that the duct 111 is supplied from the supply tube 4.3 with melted material. Furthermore it can be seen that by rotat-ing the slide plate 116 by 90~ the duct 109 supplies a connecting tube 38, 39 and 40, and not as shown in the Figures 10.1 and 10.2, the connecting tubes 38.
Under the assumption that e.g. the supply tube 4.1 for melted material supplies a melted material of blue colour, the supply tube 4.2 a melted material of green colour, and that the supply tube 4.3 supplies a melted material of red colour, all connecting tubes 38 according to the Fig. 10.2 are supplied with the material of blue colour, al connecting tubes 39 with the material of green colour and all the connecting tubes 40 with the material of red colour, whereas according to the Fig. 10.4 a connecting tube 38 is supplied with material of blue colour, another one with material of green colourand a third one with material of red colour. The same holds true for the intermediate tubes 6.2 and 6.3 for melted material. This different distribution also is shown in the Figures 8 and 9, the Fig. 10.2 corresponding to the Fig. 8,and the Fig. 10.4 to the Fig. 9.
The Figures 1 1.1 through 11.4 correspond to the Figures 8 and 9 concerning different distributors for melted material, but these Figures differ from the Fig-ures 10.3 and 10.4 in so far as the supply tubes 4.1, 4.2 and 4.3 for melted material no longer merge into the upper plate 15.1 but into the lower plate 17.1 in which a supply duct 1 12, 1 13 and 1 14 each is provided. In this arrangement the melted material from the supply tube 4.1 for melted material is conveyed via the duct 1 12 into the distributing duct 109, the material from the supply tube 4.2 via the supply duct 113 into the distributing duct 110 and CA 022~60~0 1998-12-1~

According to thè position of the slide plate 116 shown in the Fig.11.2 which corresponds to the position of this plate shown in the Fig. 8 the connecting tubes 38, 39 and 40 each are supplied with the same type of melted material whereas the according to the position of the slide plate 116 shown in the Fig.
11.4 the connecting tubes 38, 39 and 40 each are supplied with a different type of melted material.
In this arrangement the position of the slide plate 116 shown in the Fig.11.4 corresponds to the position shown in the Fig. 9.
The further elements which are designated with the same reference signs as in the preceding Figures for the sake of simplicity are not mentioned again here.
It also applies to the distributor slide 37.1 for melted material in analogy to the distributor slide 37, that the plates are combined in a manner which is to be described with reference to the following Figures.
A particularly advantageous design lay-out for effecting the rotation of the slide plate 116 is shown in the Figures 12.1 and 12.2 and is described in the following. The distributor slide 37.2 for melted material consists of an upper plate 15.2, a middle plate 18 and a lower plate 17.2, in which arrangement the upper and the lower plates 15.2 and 17.2 serve for fastening the supply tubes 4.1, 4.2 and 4.3, and of the connecting tubes 38, 39 and 40 respectively. The middle plate 18 is provided with an opening in the shape of a digit eight or of spectacles, in which arrangement in the right hand side of the eight, seen in the viewing direction of the Figure, the slide plate 116 is arranged and in the other opening at the left hand side a driving gear 19 is arranged.

08. 07.1 998 RWr/sr-271 9 Both, the slide plate 116 and the drive gear (not shown) 19 are provided with gear teeth 25 arranged on the outside which engage mutually. If the drive gear 19 is rotated manually or by a motor from the outside, this rotatory motion is transmitted to the slide plate 116 and the desired rotation is effected. By pro-viding suitable stops, or by limiting the teeth to a segment of the circle, or by other suitable measures, also not shown here, an exact angle of rotation can be ensured. If the drive gear 19 is motor driven via a motor shaft 20 of a drivemotor, e.g. of a gear motor 21, a control device 22 is provided which controls the rotation of the slide plate 116 over the above mentioned angle of 90~. For this purpose an impulse counter 23 counts rotational impulses of the motor shaft 20 and transmits them to the control device. The present invention, how-ever, is not restricted to this type of control arrangement.
The face sides of the slide plate 116, of the gear 19 and the face sides of the upper and the lower plates 15 and 17 are ground in such a manner, and to high precision, to very small tolerances, that the extremely small gap seals theindividual ducts against each other, and still ensures free rotatability. The sealing of the plates against the surrounding room is effected by correspond-ingly tight screws 24. The sealing of the shaft of the gear is effected by suitable sealing means such as seal bushings (not shown). The slide plate 116.1 is rotatably supported directly in the opening mentioned above.
This arrangement presents the advantage that a change of colour can be ef-fected without stopping the plant.
08.07.1998 RWr/sr-2719 Synthetic Thread Spinning Plant The present invention concerns a plant for spinning synthetic threads, in par-ticular for distributing melted material from a plurality of extruders to the vari-ous spinning points (spinning nozzle packs or spinnerets) of a so-called spin-ning beam.
State of the art Plants for spinning synthetic threads from melted material have been shown and described in DE-A-33 43 714 (= CH-B-657 633). Spinning beams for plants of this type can be found in the CH-B-655 520 or in the US-B-5'059'104.
In most plants the melted material is distributed by an extruder as evenly as possible to a large number of spinning points (spinning nozzle packs or spin-nerets) co-ordinated to the extruder. The filaments spun in the nozzle packs must be drawn after cooling (solidifying), possibly texturized and wound into a thread package. A draw winding machine is described e.g. in the EP-A-532 464.
Interest is growing, however, in the manufacture of multicolour threads, e.g.
according to EP-A-784 109 and/or EP-A-434 601. A method of this type re-quires a plurality of extruders which via suitable ducts for melted material areto be connected to the respective spinning points. Examples of a plant of this type can be found in the EP-A-350 450and the US-B-5'595'699. Further expla-nations can be found in the journal Chemiefasern/Textilindustrie (Synthetic Fibres/Textile Industries), October 1985, pages 668 and 672.
The task of distributing the melted material as such can be solved using con-ventional distributing means. The plant in this case becomes "dedicated" to the manufacture of multicoloured threads which is not always desirable to the plant owner. Thus there is the task, or the wish rather, hat a plant of the typementioned can be laid out flexible for producing different thread types CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 (multicolour or monochrome). A plant of such type has been mentioned in the article in Chemiefasern/Textlindustrie (Synthetic Fibres/Textile Industry) citedabove but no indications were given for solving the configuration problems.
The task could be fulfilled using valves. A solution of that type, however, results in the disadvantage that in at least one configuration "dead" (unused) ducts for melted material would be created.
The present invention thus provides a new distributor for melted material ap-plied in a plant for spinning synthetic threads. This distributor is conceived for connecting two or more sources of melted material with a greater number of sinks of melted material. The distributor correspondingly comprises at least two inlets for melted material to be connected each with a source of melted material and a greater number of outlets for melted material to be connected each to a sink for melted material. The inlets are connected via ducts to pre-determined outlets in such a manner that the melted material entering each inlet is transferred to the outlets co-ordinated to the respective inlet. The dis-tributor can be provided for a predetermined configuration of the inlets, outlets and connecting ducts in which arrangement the ducts of the plant must be ar-ranged correspondingly. The distributor, however, is laid out as an exchange-able element. The plant configuration thus can be changed by exchanging the distributor, provided that all distributors are provided with the suitable arrange-ment of the inlets, and of the outlets respectively.
The present invention of course also concerns a corresponding plant provided with the arrangement required of the ducts for the melted material. The sources of melted material normally will comprise one extruder each. The sinks of melted material normally will comprise devices forming filament, or processing filament respectively. The devices processing filaments can be "multi-thread" processing devices (processing a plurality of threads each).

08. 07.1 998 RWr/sr-271 9 Embodiments according to the present invention are explained in more detail in the following in the sense of examples with reference to the illustrated Fig-ures. All illustrations shown are of schematic nature merely. It is shown in the:

08.07.1998 RWr/sr-2719 ~ig. 12.2 the element according to the Fig. 12.1 seen in the direction V ac-cording to the Fig 12.1, shown partially simplified.
The plant according to the Fig. 1 comprises three extruders 10, 12, and 14 re-spectively, and a spinning beam 16 with spinning nozzle packs or spinnerets D1 through D18, e.g. according to WO 95/07378 and/or WO 95/00684. The extruders normally will be arranged on an upper floor and the spinning beam on a floor below. The extruders 10, 12 and 14 supply melted material of one colour each, e.g. red (R), blue (B) and yellow (G). In each spinning nozzle pack D1 through D18 a monochrome "creel thread" each is to be spun. In most cases these are multi-filament threads, the present invention, however, not being restricted to an application of this type. The colours chosen as such are of no consequence within the scope of the present invention, but the terms red (R), blue (B) and yellow (G) for the colours are also applied in the furtherexplanations in the sense of examples. The ducts for the melted material are not visible in the Fig. 1, as they are covered by heat insulating material - butthey lead into the spinning beam 16 where the melted material is to be distributed to the spinning nozzle packs or spinnerets as will be explained in the following.
Processing of the creel threads spun depends on the current production pro-gramme of the plant. In any case it must be possible to combine the creel threads into a multicoloured thread, e.g. according to EP A - 784109. For this purpose the spinning nozle packs or spinnerets are arranged in groups of three, P1 through P6, each of which is to comprise a red, a blue and a yellow creel thread. To each group also suitable processing means are co-ordinated in such a manner that a multicoloured thread can be formed from the creel threads of the respective group. As this processing manner is not of impor-tance within the scope of the present invention a further description or expla-nation is dispensed with. But the processing means are subdivided into "posi-tions" in such a manner that a "position" of one of the groups P1 through P6 is CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 co-ordinated to the spinning nozzle packs or spinnerets D1 through D18 and can process the threads supplied by the spinning nozzle packs or spinnerets of the co-ordinated group.
It should be possible also e.g. to change the plant configuration in such a manner that all spinning nozzle packs or spinnerets, or at least one group, produce monochrome (creel) threads, i.e. in this case it is undesirable to gen-erate a multicoloured thread in at least one of the groups. In other words, the configuration of the plant (in particular of the distribution ducts) should be flexible enough that the thread variety produced can be adapted to the current production programme. The processing devices of course also must be adaptable correspondingly which herein is not described in more detail as the present invention does not concern the further processing of the threads spun.
The present invention concerns the distribution of the melted material to the spinning nozzle packs or spinnerets in a flexible plant of this type.
It now is assumed that for each extruder a supply line and for each spinning nozzle pack or spinneret an individual feed line is provided. The supply lines extend from the respective extruder to a connecting or distributing point VSt inthe spinning beam 16 and the feed lines each extend from the same point VS
to the respective spinning nozle packs or spinnerets. At this point VS the mouths of the supply lines in a given arrangement (e.g. according to the Fig.
2A) are arranged side by side whereas the mouths of the feed lines also are arranged in a predetermined arrangement (e.g. according to the Fig. 2B).
These mouths are to be interconnected by means of an exchangeable con-necting means to be described in the following, in which arrangement the plant configuration can be changed by exchanging the connecting means.
The optimum arrangement of the mouths in a given plant depends on the lay-out of the plant. The arrangement shown has been chosen for the sake of sim-plicity merely and thus is to be understood in the sense of an example only. In CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 this arrangement the mouths of the feed lines are arranged in groups of three (Fig. 2B) in which arrangement these groups of mouths correspond to the groups P1 through P6 according to the Fig. 1 and form a horizontal "line" each Z1 through Z6. The mouths of the line Z1 thus are co-ordinated to the spinning nozzle packs D16 through D18. The six lines together form three vertical "columns" as the mouths of the uppermost line Z1 are arranged vertically above the corresponding mouths of the other lines. The mouths of the supply lines also form a horizontal "line" (Fig. 2A) which supply red (mouthR), blue (mouth B) and yellow (mouth G) melted material after the plant has started operation.
The base principle of the connection is explained first with reference to the Figures 3 and 4. In the Fig. 3 the mouths of the feed lines are shown again in which arrangement also three vertical connecting ducts KR1, KB1, KG1 are indicated schematically. These three ducts are co-ordinated to a supply mouth each (R, B, G, Fig. 2A) also and they co-ordinate the columns to the respective supply mouths. For this purpose the ducts KR1, KB1 and KG1 each are provided with a connecting flange SR1, SB1, SG1 which connects the duct with the mouth R, B, G. The ducts KR1, KB1, KG1 also are provided with six flanges SV which connect each duct with the mouths of the column (Fig. 2B) co-ordinated to it. In this configuration each group of spinning nozles or spin-nerets P1 through P6 is supplied with red, blue and yellow melted material and the corresponding filaments (creel threads) can be processed into a multicoloured thread.
In the Fig. 4 the mouths of the supply lines are shown in the unchanged ar-rangement but in combination with a changed distributor (compared to the one shown in the Fig. 3) which shows a changed arrangement of the ducts and of the connecting flanges. Again three connecting flanges SR2, SB2, SG2 are provided via which melted material is conveyed from the mouths R, B, G (Fig.

08.07. 1 998 RWr/sr-271 9 2A) to one of the three ducts each KR2, KB2, KG2 as will be discussed in the following:
In this example the following overall arrangement is desired (R = red, B = blue and G = yellow):
Line Position Nozle packs Creel threads Final product Z1 P1 D1, D2, D3 R, R, R three red threads Z2 P2 D4, D5, D6 B, B, B three blue threads Z3 P3 D7, D8, D9 R, B, G multicoloured thread Z4 P4 D10, D11, D12 R, B, G multicolouredthread Z5 P5 D13, D14, D15 R, B, G multicoloured thread Z6 P6 D16, D17, D18 G, G, G threeyellowthreads Each duct KR2, KB2, KG2 thus comprises a vertical leg KR2S, KB2S, KG2S
and a horizontal leg KR2W, KB2W, KG2W. The horizontal leg KR2W is con-nected via the connecting flanges VS with all the mouths of the line Z1, the horizontal leg KB2W with all the mouths of the line Z2, and the horizontal leg KG2W with all the mouths of the line Z6. The vertical leg KR2S via the corre-sponding connecting flanges is connected with the "further" mouths of the left side column, the vertical leg KB2S with the further mouths of the middle col-umn, and the vertical leg KG2S with the further mouths of the right side col-umn.
There are, of course, a great number of possibilities of establishing the re-quired connections. In the preferred variant exchangeable connecting means are prepared in such a manner that by exchanging the connecting means cur-rently in use the plant configuration can be changed.
In the Fig. 5 a connecting element is shown which could be applied in an ex-changeable means for establishing the arrangement according to the Fig. 3.
CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 This connecting element comprises the connecting flanges SR1 (Fig. 3), the duct KR1 (Fig. 3) and six connecting flanges SV1 through SV6 for connecting the connecting element with the mouths of the left side column according to the Fig. 3. Each of the flanges SR1, and SV1 through SV6 respectively, is pro-vided with a coupling means KM (indicated schematically merely) for coupling it to corresponding coupling means on the supply line, or on the feed lines re-spectively. The exchangeable connecting means in this variant comprises three connecting elements of this type which each are co-ordinated to one of the mouths R, B, G (Fig. 2A). The three connecting elements can combined into a connecting device by means of a suitable holder (not shown) which, however, is not mandatory.
Similar (but more complicated) connecting elements could be designed for establishing the connection according to the Fig. 4.
The connections preferentially are established by applying an exchangeable element (e.g. a plate or a pack of plates). The mouths (Figures 2A and 2B) could be provided e.g. in end plates and the distributor element (the distributor plate) could be attached in between (using suitable sealing elements). In an example the connecting element comprises a distributor pack consisting of two plates pressed against each other. The connecting flanges extend through the thickness of one of the plates, the flanges SR, SB, SG extend through the thickness of the other plate. The ducts KR, KB, KG are provided in the surface of one plate facing the other plate e.g. in the form of grooves. Of course the grooves could be provided also in both plates.
In the Fig. 6 three extruders are shown designated with the reference numbers 101, 102 and 103 in which arrangement each of the extruders supplies a dif-ferent melted material. In this arrangement the differences in the melted mate-rials could concern the colour (e.g. B = blue, G = yellow, R =red) or other characteristics of quality or appearance.
CA 022~60~0 1998-12-1~
08. 07. 1998 RWr/sr-271 9 From each extruder 101, 102, 103 a supply duct for melted material each de-signated 4.1, 4.2 and 4.3 extends separately into a distributor 5 for melted material.
Via this distributor 5 the melted material from the extruder 101 is distributed via intermediate tubes for melted material 6.1, from the extruder 102 via the intermediate tubes for melted material 6.2 and from the extruder 103 via intermediate tubes for melted material 6.3 each into spinning pumps 7 and subsequently to the spinning nozzle packs or spinnerets 8. From this it can be seen that four spinning nozle packs or spinnerets arranged side by side each are supplied with the same melted material.
The distributor 5 for melted material shown in the Fig. 6.1 in more detail is pro-vided with three distributor plates for melted material which are superimposed and held together and stationary by elements not shown.
In this arrangement the melted material from the extruder 101 is guided via the intermediate tubes 6.1 for the melted material and via the upper distributor plate 51, the melted material from the extruder 102 via the intermediate tubes 6.2 and via the middle distributor plate 52, and the melted material from the extruder 103 via the intermediate tubes 6.3 and via the lower distributor plate 53.
In this arrangement distribution of the intermediate tubes 6.1 is provided in one longitudinal direction of the rectangular distributor for melted material, whereas distribution of the intermediate tubes 6.2 is provided in another longitudinal direction, and distribution of the intermediate tubes 6.3 is provided in a further longitudinal direction of the rectangular distributor for melted material, whereas the supply tubes for melted material 4.1, 4.2 and 4.3 are provided in the fourth longitudinal direction of the distributor 5 for melted material, i.e. a spinning nozzle pack or spinneret 7 is supplied three times with the same melted material which using the connecting tubes 38, 39 and 40 are CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-271 9 supplied to the corresponding spinning pumps 7. I.e. that in this arrangement the tubes 38 conduct e.g. the melted material B, the tubes 39 e.g. the melted material G and the tubes 40 e.g. the melted material R.
In the Fig. 7 the same extruders 101, 102 and 103 are shown with e.g. the same distribution of melted material per extruder as indicated in the Fig. 6 andalso the same supply tubes for melted material 4.1, 4.2 and 4.3 which conduct the melted material to the distributor for melted material designated 5.1 here.
The arrangement of the intermediate tubes for the melted material 6.1, 6.2 and 6.3 here differs from the one shown in the Fig. 6.
The difference is seen in that a spinning nozle pack or spinneret is supplied with each melted material, i.e. in the present case three different kinds of melted materials, namely the types of melted material B, G and R. Accordingly the intermediate tubes for melted material 6.1, 6.2 and 6.3 extend from each of the above mentioned longitudinal directions of the distributor for melted mate-rial away towards the spinning pumps 7.
The advantage of these superimposed distributor plates is seen in that that, firstly, the whole system of connecting tubes between the distributor 5, or 5.1 respectively, for melted material and the spinning pumps 7 can be maintained unchanged if the supply of melted material is changed, and that, secondly, in the corresponding plates all ducts can be provided adapted to the distribution according to the distributor 5, or 5.1 respectively, for melted material, i.e. that if the distribution of the melted material is to be changed, the flows of meltedmaterial can be deviated e.g. by placing inserts (not shown) in the horizontal ducts of the individual plates 51, 52, 53, or 51.1, 52.1, 53.1 respectively.
If these ducts in the distributor plates, extending in the directions of the sur-faces, each are carved into the surface of each plate, a fourth plate 36 is pro-vided, indicated with dash-dotted lines, in such a manner that the ducts carved into the uppermost plate 51.1, or 52.1, or 53.1 respectively, can be covered.

08.07. 1 998 RWr/sr-2719 -11 -In the Fig. 8 instead of the distributor 5 a slide plate 116 of a distributor slide for melted material 37 (Figures 10.1 through 10.4), or 37.1 (Figures 1 1.1 through 11.4) is shown which will be explained in more detail in the following with reference to further Figures.
The slide 37 in this arrangement, as shown schematically, is provided, for each type of melted material from the extruders 101, 102 and 103, with a distributor duct 109, and 110 and 111 respectively, into which a supply duct for melted material each merges, e.g. the melted material from the extruder 101 via the supply tube 4.1 for melted material into the duct 109, the melted material from the extruder 102 via the distributor tube 4.2 into the duct 110 and the melted material from the extruder 103 via the distributor tube 4.3 into the duct 111. In this arrangement each of the ducts is connected with three outlets for melted material to which the connecting tubes 38, and 39 and 40 respectively, are connected.
In the example according to the Fig. 8 the melted material is distributed via the connecting tubes 38 to two group spinning pumps 7 and from there to four spinning nozzle packs or spinnerets 8. The same distribution mode is provided for the melted material from the extruder 102 via the connecting tubes 39, and for the melted material from the extruder 103 via the connecting tubes 40.
The ducts 109, 110 and 11 1 are laid out, as to be described later, in the slideplate 16 in such a manner that the position of the ducts 109, 110 and 1 11 can be brought into a position shown in the Fig. 9 if the plate is shifted, or rotated respectively, by 90~.
In the arrangement according to the Fig. 8 the distribution of the melted mate-rial corresponds to the one according to the Fig. 6 and the distribution of the melted material shown in the Fig. 9 corresponds to the one shown in the Fig.
CA 022~60~0 1998-12-1~
08. 07.1 998 RWr/sr-271 9 7, i.e. each spinning nozzle pack or spinneret 8 is supplied with all three types of melted material B, G and R.
In the Figures 10.1 through 10.4 the distributor slide 37 for melted material mentioned earlier is shown.
In the Fig. 10.1 the above mentioned distributor slide 37 is shown with an up-per plate 15, a lower plate 17 and the slide plate 1 16 arranged in between.
The supply distributing tubes 4.1, 4.2 and 4.3 merge into the upper plate 15 and to the lower plate 17 the connecting tubes 38, 39 and 40 are connected.
In the Fig. 10.2 a cross-section is shown of the slide plate 116 along the linesl-l shown in the Fig. 10.1, from which the ducts 109, 110 and 111 mentioned earlier can be seen.
From the Figures 10.1 and 10.2 it can be seen that the supply tube 4.1 for melted material merges into the duct 109, the tube 4.2 merges into the duct 110 and the tube 4.3 merges into the duct 111 each via the upper plate 15.
The connecting tubes 38 merge threefold through the lower plate 17 namely from below, as seen in the viewing direction of the Fig. 10.1, into the duct 109, whereas the connecting tubes 39 merge via the lower plate 17 into the duct 110 and the connecting tubes 40 merge via the lower plate 17 into the duct 111.
In a later Figure it will be shown that the upper plate 15 and the lower plate 17 are arranged stationary whereas the slide plate 116 can be shifted, or rotated respectively, relative to the stationary plates by 90~, namely about the axis ofthe supply tube for melted material 4.2.
This state of the slide plate 116 rotated by 90~ is shown in the Figures 10.3 and 10.4.
-CA 022~60~0 1998-12-1~
08.07. 1 998 RWr/sr-27 19 -1 3-From this arrangement it can be seen that the positions of the supply tubes for melted material 4.1, 4.2 and 4.3 as well as the positions of the connecting tubes 38, 39 and 40 are the same and that the duct 109 is supplied from the supply tube 4.1 with melted material, that the duct 110 is supplied from the supply tube 4.2 with melted material and that the duct 111 is supplied from the supply tube 4.3 with melted material. Furthermore it can be seen that by rotat-ing the slide plate 116 by 90~ the duct 109 supplies a connecting tube 38, 39 and 40, and not as shown in the Figures 10.1 and 10.2, the connecting tubes 38.
Under the assumption that e.g. the supply tube 4.1 for melted material supplies a melted material of blue colour, the supply tube 4.2 a melted material of green colour, and that the supply tube 4.3 supplies a melted material of red colour, all connecting tubes 38 according to the Fig. 10.2 are supplied with the material of blue colour, al connecting tubes 39 with the material of green colour and all the connecting tubes 40 with the material of red colour, whereas according to the Fig. 10.4 a connecting tube 38 is supplied with material of blue colour, another one with material of green colourand a third one with material of red colour. The same holds true for the intermediate tubes 6.2 and 6.3 for melted material. This different distribution also is shown in the Figures 8 and 9, the Fig. 10.2 corresponding to the Fig. 8,and the Fig. 10.4 to the Fig. 9.
The Figures 1 1.1 through 11.4 correspond to the Figures 8 and 9 concerning different distributors for melted material, but these Figures differ from the Fig-ures 10.3 and 10.4 in so far as the supply tubes 4.1, 4.2 and 4.3 for melted material no longer merge into the upper plate 15.1 but into the lower plate 17.1 in which a supply duct 1 12, 1 13 and 1 14 each is provided. In this arrangement the melted material from the supply tube 4.1 for melted material is conveyed via the duct 1 12 into the distributing duct 109, the material from the supply tube 4.2 via the supply duct 113 into the distributing duct 110 and CA 022~60~0 1998-12-1~

According to thè position of the slide plate 116 shown in the Fig.11.2 which corresponds to the position of this plate shown in the Fig. 8 the connecting tubes 38, 39 and 40 each are supplied with the same type of melted material whereas the according to the position of the slide plate 116 shown in the Fig.
11.4 the connecting tubes 38, 39 and 40 each are supplied with a different type of melted material.
In this arrangement the position of the slide plate 116 shown in the Fig.11.4 corresponds to the position shown in the Fig. 9.
The further elements which are designated with the same reference signs as in the preceding Figures for the sake of simplicity are not mentioned again here.
It also applies to the distributor slide 37.1 for melted material in analogy to the distributor slide 37, that the plates are combined in a manner which is to be described with reference to the following Figures.
A particularly advantageous design lay-out for effecting the rotation of the slide plate 116 is shown in the Figures 12.1 and 12.2 and is described in the following. The distributor slide 37.2 for melted material consists of an upper plate 15.2, a middle plate 18 and a lower plate 17.2, in which arrangement the upper and the lower plates 15.2 and 17.2 serve for fastening the supply tubes 4.1, 4.2 and 4.3, and of the connecting tubes 38, 39 and 40 respectively. The middle plate 18 is provided with an opening in the shape of a digit eight or of spectacles, in which arrangement in the right hand side of the eight, seen in the viewing direction of the Figure, the slide plate 116 is arranged and in the other opening at the left hand side a driving gear 19 is arranged.

08. 07.1 998 RWr/sr-271 9 Both, the slide plate 116 and the drive gear (not shown) 19 are provided with gear teeth 25 arranged on the outside which engage mutually. If the drive gear 19 is rotated manually or by a motor from the outside, this rotatory motion is transmitted to the slide plate 116 and the desired rotation is effected. By pro-viding suitable stops, or by limiting the teeth to a segment of the circle, or by other suitable measures, also not shown here, an exact angle of rotation can be ensured. If the drive gear 19 is motor driven via a motor shaft 20 of a drivemotor, e.g. of a gear motor 21, a control device 22 is provided which controls the rotation of the slide plate 116 over the above mentioned angle of 90~. For this purpose an impulse counter 23 counts rotational impulses of the motor shaft 20 and transmits them to the control device. The present invention, how-ever, is not restricted to this type of control arrangement.
The face sides of the slide plate 116, of the gear 19 and the face sides of the upper and the lower plates 15 and 17 are ground in such a manner, and to high precision, to very small tolerances, that the extremely small gap seals theindividual ducts against each other, and still ensures free rotatability. The sealing of the plates against the surrounding room is effected by correspond-ingly tight screws 24. The sealing of the shaft of the gear is effected by suitable sealing means such as seal bushings (not shown). The slide plate 116.1 is rotatably supported directly in the opening mentioned above.
This arrangement presents the advantage that a change of colour can be ef-fected without stopping the plant.
