In particular, the number of partial wetting devices can be so great that the joining device can be operated continuously during operation of the textile machine, in particular at full power.

As an alternative or in addition to a continuous operation of the joining device, it is possible for the thread wetting device to be arranged downstream of a temporary storage device in the area of the thread supply device, so that the operation of the thread wetting device and the operation of the joining device can be decoupled from one another during operation of the textile machine. If a decoupled operation is realized, the operation of the thread wetting device generally takes place continuously during operation of the textile machine and the operation of the joining device intermittently.

The present invention will be explained below in connection with the dyeing of threads. However, it is not limited to dyeing threads, but is generally applicable to wetting threads.

According to the Figures 1 and 2 are stored on a thread supply device 1 a textile machine, a plurality of threads 2. In FIG. 2 only a few of the threads 2 are shown. In practice, the number of threads 2 is usually over 1000, sometimes even several 1000. Since the present invention will be explained below in connection with a trained as a weaving machine textile machine, the threads 2 are hereinafter referred to as warp threads 2. In principle, however, the textile machine according to the invention could also be designed differently, for example as a knitting machine. The thread supply device 1 may be formed as a uniform thread supply device 1, for example as a so-called warp beam. Alternatively, the thread supply device 1 may comprise a number of individual coils, on each of which a single or a few of the warp threads 2 are wound.

The textile machine according to the invention also has a thread feeding device 3. From the yarn feeding device 3, the plurality of yarns 2 is withdrawn from the yarn supply device 1 and fed to a joining device 4. From the joining device 4, the plurality of threads 2 to a flat Textile material 5 joined. In the present case, in which the textile machine is designed as a weaving machine, the joining device 4 is designed as a weaving device. The warp threads 2 are woven in the weaving device 4 by means of a weft thread 6 to the fabric 5.

The textile machine according to the invention also has a stripping device 7. By means of the stripper 7, the sheet textile material 5 is removed from the joining device 4. The stripping device 7 may be identical to a collecting device for the flat textile material 5. For example, the stripper 7 may be formed as a so-called cloth tree of the loom.

As already mentioned, the textile machine is designed in the present case as a loom. In operation, the textile machine iteratively executes the following sequence of operations: First, a top compartment 8 and a bottom compartment 9 are opened. The weft thread 6 is guided by the open compartments 8, 9. Then, the weft thread 6 is struck by means of a Riets 10 to a fabric edge 11. Next, the upper compartment 8 and the lower compartment 9 are closed. Both the opening and the closing of the compartments 8, 9 takes place by means of thread guides 12. The thread guides 12 are part of the joining device 4. The area between the thread guides 12 and the thread supply device 1 corresponds to the area of the thread feeding device 3.

In the area of the thread feeding device 3, a thread dyeing device 13 is arranged. By means of the thread dyeing device 13, the threads 2 can be dyed in one or more colors, for example in yellow, red, green, blue or in yellow and red (so that an orange tone results), etc. According to FIG. 3 (see the left part there), it is possible that the threads 2 are individually dyeable. It will be - purely exemplary - the in FIG. 3 top thread 2 dyed in a first color (for example, red), the next thread 2 in a second color (for example, green), the next thread 2 is not dyed, the next thread 2 is colored in blue and yellow, etc. .. For each thread 2 is individually (ie independently of the other threads 2) adjustable, whether and how he is optionally dyed.

Alternatively, it is possible that the above statements apply to a group of adjacent threads 2, for example, as shown in the right part of FIG FIG. 3 in each case for three adjacent threads 2.

The entire textile machine is controlled by means of a control device 14. The control device 14 also controls the thread dyeing device 13. The thread dyeing device 13 is connected for this purpose with the control device 14 in terms of data technology. The control device 14 controls the thread dyeing device 13 such that each thread 2 or each group of threads 2 is dyed or not dyed in accordance with the control by the control device 14 over respective partial lengths 15.

The partial lengths 15 can be specified individually for each thread 2 (or each group of threads 2). It is determined by the control device 14 for each individual thread 2 (or for each group of threads 2) in which partial lengths 15 of the respective thread 2 (or the respective group of threads 2) is dyed by means of the thread dyeing device 13 and in which Color or in which colors this optionally takes place.

The threads 2 have a thread thickness d. When the threads 2 are dyed individually, the part lengths 15 are set by the control device 14 with an accuracy which lies in the range of the thread thickness d. So if so FIG. 4 one of the threads 2 is to be colored over a desired length l *, controls the control device 14, the thread dyeing device 13 such that the corresponding thread 2 via a corresponding actual length l is dyed. A grid r, as the integral multiple of which the desired length l * is specified, is in the range of the thread thickness d. Any difference δl between the nominal length l * and the actual length l is considerably smaller than the grid dimension r.

gilt. Im Einzelfall kann hierbei der Wert "2" geringfügig überschritten werden.The term "within the range" is to be understood in the context of the present invention such that the relationship $$r/d\le 2$$

applies. In individual cases, the value "2" can be slightly exceeded.

In an analogous manner, the above relationship also applies when groups of threads 2 are dyed. In this case, in the above relationship, instead of the thread thickness d, the "sum thickness" should be used, that is, n · d, where n = the number of threads 2 per group.

In principle, it is possible that the grid dimension r is considerably smaller than the thread thickness d or n times the thread thickness d. In the context of the present invention, however, such a small pitch r usually does not make sense. As a rule, therefore, the relationship applies $$0.5\le r/n\cdot d\le 2$$

With the special case n = 1 usually applies $$0.5\le r/d\le 2$$

In many cases, the dyeing of the threads 2 by means of the thread dyeing device 13 is slower (sometimes even considerably slower) than the joining of the threads 2 to the sheet-like textile material 5. In some cases - especially in looms - it is still possible, an operating speed to reduce the joining device 4. Any reduction to very slow working of the joining device 4, however, is not possible. Rather, it must always be worked with a minimum speed or the operation of the joining device 4 can be set. Especially in such a case, the thread dyeing device 13 is according to FIG. 2 in the region of the yarn feeding device 3 preferably a buffer device 16 downstream. In the temporary storage device 16, the threads 2 are cached after leaving the thread dyeing device 13. This makes it possible to decouple the operation of the thread dyeing device 13 and the operation of the joining device 4 from each other. Buffering devices as such are known in this case. Purely by way of example is on the US 4,915,282 A and the US 2004/118892 A1 directed.

By the intermediate storage in the temporary storage device 16 can be achieved in particular that the operation of the joining device 4 can be done intermittently, while the thread dyeing device 13 is operated continuously. In this case, the operation of the joining device 4 is set in a first phase of the operation of the textile machine. The temporary storage device 16 fills up. When a certain degree of filling of the temporary storage device 16 is reached - for example 95% -, the operation of the joining device 4 is recorded. The operation of the thread dyeing device 13 is maintained. Since the joining device 4 inserts the threads 2 faster than the thread dyeing device 13 dyes the threads 2, the intermediate storage device 16 empties. When a certain degree of filling of the intermediate storage device 16 is reached - for example 5% - the operation of the joining device 4 is discontinued.

The intermittent operation of the joining device 4 is particularly necessary when the threads 2 have to be dyed by means of a single, uniform thread dyeing device 13. In a preferred embodiment of the present invention Invention is therefore according to FIG. 5 provided that the thread dyeing device 13 has a plurality of Teilfärbeeinrichtungen 17. Of each Teilfärbeeinrichtung 17 is a respective part of the threads 2 dyeable. The partial dyeing device 17 are controlled by the control device 14 simultaneously. Each partial dyeing device 17 is individually controlled by the control device 14, so that it "dyes" its "threads 2" accordingly.

In FIG. 5 Four partial dyeing devices 17 are shown purely by way of example, wherein by means of each of the partial dyeing devices 17, a respectively contiguous region of the adjacent threads 2 can be dyed. This illustration is purely exemplary. Alternatively, for example, it is possible that the first, the fifth, the ninth, the thirteenth, etc., threads 2 are dyeable by means of a first partial dyeing device 17, the second, sixth, tenth, fourteenth, etc., threads 2 can be dyed by means of a second partial dyeing device 17 third, seventh, eleventh, fifteenth, etc. are filament 2 dyed and by means of a fourth Teilfärbeeinrichtung 4 of the fourth, eighth, twelfth, sixteenth, etc. thread 2 are dyeable. Furthermore, it is possible to design the thread dyeing device 13 such that one and the same thread 2 can be dyed by means of a plurality of partial dyeing devices 17. For example, each thread 2 can be dyed by means of two Teilfärbeeinrichtungen 17. This makes it possible to color a first part length 15 of a thread 2 with the first part dyeing device 17 and to color a second part length 15 of the same thread 2 with a second part dyeing device 17.

By providing a plurality of partial dyeing devices 17, the speed with which the threads 2 are dyed can be increased. Depending on the number of partial dyeing devices 17 and the associated extent of speed increase, it may be possible for the joining device 4 to operate continuously becomes. The continuous operation of the joining device 4 may alternatively be possible with reduced power or at full power.

In the case that the joining device 4 is operated continuously, the intermediate storage device 16 can be dispensed with. Preferably, the latching means 16 is also present in this case. The temporary storage device 16 can be maintained, for example, in a normal operation of the textile machine at a filling level of about 50%, so that in an unexpected disturbance of one of the two facilities thread dyeing device 13 and joining device 4, the respective other device 4, 13 can continue to operate for a limited time. Also, before a scheduled maintenance of one of the two facilities Fadenfärbeeinrichtung 13 and joining device 4, the degree of filling of the buffer device 16 can be varied accordingly, so that as long as possible further operation of the other device 4, 13 can be maintained.

In some cases it is not necessary to treat the threads 2 further after dyeing. As a rule, it is necessary to actively fix the paint applied to the threads 2. This is done by means of a fixing device 18, the thread dyeing device 13 according to FIG. 2 downstream in the field of yarn feeding device 3. If the temporary storage device 16 is provided, the fixing device 18 may alternatively be arranged inside or outside the intermediate storage device 16. If the fixing device 18 is arranged inside the temporary storage device 16, the fixing takes place during the temporary storage.

The fixing process as such is designed as needed. For example, an active drying of the paint can take place. For this purpose, for example, the threads 2 can be irradiated with heat radiators or by means of a schematic shown blower 19 air 20 are blown onto the threads 2. The air 20 may optionally be heated in the fan 19 similar to a hair dryer.

So that the colors can be applied in a location-accurate manner to the threads 2, the threads 2 must be correspondingly FIG. 6 run relative to the thread dyeing device 13 transversely to a transport direction x of the threads 2 locally fixed. Preferably, it is appropriate FIG. 6 arranged in the thread dyeing device 13 a lateral guide 21. By means of the lateral guide 21, the threads 2 are guided so that the threads 2 pass through the thread dyeing device 13 transversely to a transport direction x of the threads 2 at predetermined lateral positions. For example, the threads 2 as shown by FIG. 6 be guided over pairs of rollers 22, wherein the rollers 22 according to FIG. 7 each have a number of guide grooves 23 for the threads 2. As a result, the threads 2 are fixed transversely to the transport direction x both in a width direction y and in a height direction z relative to the thread dyeing device 13.

The control device 14 executes a sequence during operation. The sequence of execution may be determined, for example, by a control program 24 with which the control device 14 is programmed. It is possible that the way in which the threads 2 are colored is already determined by the design of the sequence of operations. Their particular advantages, the present invention, however, in another embodiment, hereinafter in conjunction with FIG. 8 is explained in more detail. FIG. 8 shows a broad outline of a preferred embodiment of the flow sequence, which executes the control device 14.

According to FIG. 8 takes the controller 14 in a step S1 against a planar pattern 25. The planar pattern 25 is supplied to the control device 14 by a detection device 26 which is assigned to the control device 14.

The detection device 26 may be configured as needed. For example, it may be in the detection device 26 accordingly FIG. 9 to handle a camera, a scanner, or an input interface. Also, several such input devices 26 may be present.

If the detection device 26 is designed as a camera, the areal pattern 25 is an image of a three-dimensional scene captured by the camera 26. If the detection device 26 is designed as a scanner, the areal pattern 25 is an image of a two-dimensional image which is given to the scanner 26. In both cases, the areal pattern 25 of the input device 26 is given as a natural image. If the input device 26 is designed as an input interface, the areal pattern 25 of the input interface 26 is specified in electronic form, for example as a JPG image, as a TIFF image, as a PDF image, as a BMP image, etc.

In a step S2, the control device 14 rasterizes the planar pattern 25 given to it.

In a (optional and therefore only shown in phantom) step S3, the control means 14 summarizes possibly existing contiguous larger areas of the planar pattern 25 together.

In a step S4, the control device 14 automatically determines control commands for the thread dyeing device 13. The determination takes place in such a way that the threads 2 are dyed corresponding to the flat pattern 25. In a step S5, the control device 14 controls the thread dyeing device 13 in accordance with the control commands it has determined.

vollständig (oder fast). d ist die Fadendicke. n ist entweder eins (Stichwort individuelles Färben einzelner Fäden 2) oder gleich der Anzahl an Fäden 2 pro Gruppe. In der Regel gilt sogar die Bedingung $$0,5\le r/n\cdot d\le 2$$

The flat textile material 5 produced in accordance with the invention has correspondingly FIG. 10 a variety of threads 2, which extend in a common thread running direction x. Woven material 5 is the warp threads 2. Seen in the thread running direction x, the threads 2 are dyed individually or in groups of threads 2 lying transversely to the thread running direction x over respective partial lengths 15 individually in at least one of several colors or not dyed , The partial lengths 15 define a grid r, that is, each partial length 15 is - in the context of minor tolerances - an integer multiple of the grid r. The r r satisfies the condition $$r/n\cdot d\le 2$$

completely (or almost). d is the thread thickness. n is either one (keyword individual dyeing of individual threads 2) or equal to the number of threads 2 per group. In general, even the condition applies $$0.5\le r/n\cdot d\le 2$$

Furthermore, transverse to the thread running direction x, ie in a transverse direction y, further threads 6. In the case of a fabric 5, these are the weft threads 6. These threads 6 are not colored in the manner explained above, but - at least in the rule - uniformly colored or undyed.

The present invention has many advantages. In particular, the use of different further threads 6 (weft threads 6) while maintaining the thread dyeing device 13 can be used to produce the same basic motif in different variants. Furthermore, individual prints on textiles can be realized in a high quality way. Also photorealistic motifs can easily be produced. Also, a coloring of the threads 2 is not necessarily required. It can also be done a different wetting, for example, for production electrically conductive structures on the sheet-like textile material 5.

The above description is only for explanation of the present invention. The scope of the present invention, however, is intended to be determined solely by the appended claims.
