    Description: The invention relates to a textile structure, a device and a method for producing a textile structure.
    Known textile structures are in particular fabrics, knitted fabrics and knitted fabrics. While the latter two arise from loops through stitch formation, a fabric consists of crossing thread systems. All these textile structures have in common that they usually have a constant basis weight in all areas in conventional production.
    For special applications, it is desirable to reinforce textile structures. In particular for so-called composite applications, there is a great need for special reinforcement structures. For this purpose, reinforcement threads can be integrated into the knitted structures of knitted or crocheted fabrics. In the case of fabrics, the reinforcement can be carried out using suitable crossing threads. Of great importance with regard to material efficiency is the correct design of the structures.
    [0004] Various technologies are known for integrating reinforcing threads. In the so-called 3D braiding with concentric bobbin laces, for example, the bobbins run on flat lanes which are concentric with one another, and the bobbins can be exchanged between the lobes. Changes in the direction of the bobbin are also possible with other known braiding methods. On the other hand, knitting, due to the process, means that knitted fabrics can only be produced to a limited extent or not at all due to the longitudinal thread system. A contour can be tied off by varying the binding. In a subsequent, mostly manual cutting process along the set contour, this is removed.
    Furthermore, methods for warp thread manipulation are known in which an alignment of additional warp threads is realized, which is always associated with a local change in the basis weight. With open reed weaving, for example, a limited number of additional threads can be introduced into a base fabric in order to realize reinforced areas there. A fabric with a locally varying basis weight is obtained.
    It is an object of the present invention to provide a final structure-appropriate textile structure, in particular a textile reinforcement structure, with high material efficiency, preferably a specifically adjustable, in particular constant in all areas, weight is realized. A corresponding device and a corresponding method are also to be proposed.
    [0007] This object is achieved by the features of the independent claims.
    The textile structure according to the invention is characterized in that it has double-function threads, each of which has sections running both in the weft and in the warp direction. Here, the term “warp thread sections of the double-function threads running in the warp direction” is to be understood to mean that these double-function threads are not
    - at least not always - after crossing the textile structure in the weft direction, it is immediately deflected by 180 ° at the textile structure edge and entered into the textile structure in the opposite direction, forming the next weft thread row. Rather, after they have passed through the textile structure as a weft thread, the double-function threads can pass a plurality of rows of weft threads in the warp direction, forming a said warp thread section, before again crossing the warp direction as a weft thread section running in the opposite direction. The double-function threads therefore run in sections in the weft direction and in sections in the warp direction - this course preferably being repeated several times in the warp and weft directions. There is no need for a repeating entry pattern; such is preferably also not implemented.
    In other words, the double-function threads take on the one hand warp thread and on the other hand weft thread function (hence the name "double-function thread"). In a course section, the double-function threads accordingly act as, for example, conventional warp threads, which - for example when the textile structure is designed as a woven fabric
    - Run between or next to linearly aligned warp threads (if there are any) and assume the position of warp threads in these sections, and in a different section than, for example, conventional weft threads, which preferably cross other double-function threads and any existing linear warp threads.
    A double-function thread, if it runs in a section in the warp direction, thus acts in this section like an actual warp thread which is crossed by weft threads and / or by other double-function threads running in the weft direction at this point. The double-function threads thus take on the warp thread function on the one hand and the weft thread function on the other hand.
    The double-function threads can thus in particular act as at least biaxial reinforcing threads, which means that it is possible to incorporate all the reinforcing threads over the working width required in accordance with the geometry in one production step.
    The double function threads can be the only threads present in the textile structure. Alternatively, further threads can be present, for example exclusively over the entire length of the textile structure, warp threads running linearly in the warp direction and / or exclusively weft threads and / or mesh threads running linearly in the weft direction, which can serve in particular to fix the double-function threads.
    CH 710 063 B1 It is also possible that in certain (ie not all) sections of the textile structure all double-function threads in warp or all double-function threads in the weft direction or at least some of the double-function threads in warp and another part are oriented in the weft direction can.
    The targeted re-functionalization of threads, that is, according to the invention by the provision of the double-function threads, enables textile reinforcement structures to be implemented, in which preferably all double-function threads serving to reinforce the textile structure are incorporated. The waste of reinforcing thread material during the manufacture of the textile structure can therefore be kept to a minimum or avoided entirely. This enables textile reinforcement structures to be produced with maximum material and resource efficiency. For this purpose, the textile structure according to the invention in most cases has a large number of double-function threads.
    The terms "warp direction", "warp thread", "warp thread sections" and "weft direction", "weft thread" and "weft thread sections" used in the present case are to be interpreted in general terms, that is to say in particular not to be understood as restricted to fabrics. “Warp direction” generally means the transport direction of the textile structure (generally designated 0 °), “weft direction” the transverse direction to the warp direction (generally designated 90 °), the term “weft direction” here being intended to encompass both opposite directions. A "warp thread" is a thread that has a generally continuous orientation in the warp direction, while a weft thread is a thread that has a general orientation in the weft direction. The double-function threads according to the invention have no exclusive courses in the warp or weft direction, but have both warp and weft sections in their course.
    The preferred embodiment of the textile structure according to the invention is a scrim, knitted fabric, knitted fabric or a fabric, in particular a leno fabric. In the case of laid fabrics, knitted fabrics and knitted fabrics, according to advantageous embodiments, in addition to the double-function threads - and possibly existing warp threads and / or possibly existing weft threads - there are also stitch threads for fixing the double-function threads (and possibly the warp threads and / or possibly the weft threads ) integrated in the textile structure. The stitch threads themselves have only a slight reinforcing function in, for example, the warp and weft directions or perpendicularly to them.
    A textile structure according to the invention can consist of one type of thread (natural or synthetic threads or mixed threads) or of different types of thread. For example, a combination of natural fiber threads and high-performance reinforcing fibers, which are formed by some or all of the double-function threads, is possible.
    By means of the invention, at least biaxial (or even higher axial, e.g. triaxial) reinforcement thread arrangements can be realized. The simplest, i.e. Biaxial, design creates a significant improvement over known textile reinforcement structures.
    The double-function threads — and possibly also warp threads and / or weft threads — are particularly preferably introduced into the textile structure at constant distances from one another in the warp and weft directions in such a way that the textile structure has a uniform, constant weight per unit area. In this case, there are preferably essentially the same distances between the optionally additionally available warp threads and warp thread sections of the double-function threads, on the one hand, and the same distances between the weft thread sections and, if appropriate, additionally present weft threads on the other hand. Additional threads can be added, but in many cases they are not necessary.
    To achieve a near-net shape textile structure, this has a varying width in the preferred embodiment, i.e. the width of the textile structure varies over several rows of weft threads, the textile structure preferably having a number of rows of warp threads that changes in the warp direction (KR). Here, one or both longitudinal edges of the textile structure are not continuously linear in the warp direction. For example, a section-by-section waist of the textile structure is possible or an asymmetrical tapering of the one textile structure edge to the other textile structure edge, which for example runs linearly in the warp direction. In general, a wide variety of geometries of the textile structure can be realized. The width of the textile structure can decrease or increase monotonically or strictly monotonously over several weft rows.
    It is particularly preferred that at least one of the double-function threads cuts a different total number of possibly existing warp threads and warp-thread sections of other double-function threads in its different weft thread sections. The total number is the sum of the warp thread sections of the double-function threads that are crossed during a weft pass and the warp threads that may be present. In other words, the length of successive weft sections of one or more double-function threads is therefore not always the same. In the case of weft thread sections running from one edge of the textile structure to the other edge, the width of the textile structure is then not constant. A specifically desired textile structure geometry can thus be realized, particularly preferably with a constant weight per unit area. Alternatively, if the weft length is unequal, the double-function thread can only be shot through part of the textile structure, i.e. inside the textile structure are deflected in the warp direction and then preferably run a certain distance with the crossing of several weft rows in the warp direction. A double-function thread can also take both of the above-mentioned types of course on its way through the textile structure.
    Overall, the double-function threads serving as reinforcement threads can be used to produce textile reinforcement structures close to the final contour with a high material efficiency with a constant weight per unit area. Partial oversizing or local differences in thickness in the textile reinforcement structure can therefore be avoided.
    CH 710 063 B1 [0023] According to preferred embodiments, one or more openings or openings can be realized in the textile structure by means of the double functional threads. For this purpose, they are guided in such a way that the regular arrangement of the threads present in the textile structure is interrupted. For this, e.g. Warp thread sections (or weft thread sections) of double-function threads in one place, e.g. in the middle, the textile structure is led out of it and integrated again as weft sections (or warp thread sections). The threads removed within the textile structure can also be arranged according to the pattern at the edge of the textile structure, for example in order to realize a broadening of the textile structure. Instead of or in addition to openings or openings, other geometries can also be realized by the described procedure, for example bifurcations in the textile structure.
    Particularly preferably, at least some of the double-function threads and preferably all double-function threads run from one longitudinal textile structure edge to the other textile structure edge, i.e. the double function threads extend in the weft direction over the entire local textile structure width. At the textile structure edges, a double-function thread, preferably in many places, is guided in the warp direction at least over two successive weft threads or weft thread rows before it is again deflected through 90 ° into the textile structure. It is expressly to be emphasized that double-function threads in other sections immediately, i.e. without crossing the weft thread row adjacent in the warp direction, can be deflected by 180 ° and then cross the textile structure in the opposite direction as a weft thread.
    The double-function threads particularly preferably intersect when several of them run along a longitudinal textile structure edge. In other words, in the warp direction, one double-function thread "overtakes" another, which in turn is inserted into the textile structure earlier than the double-function thread running further along the textile structure edge.
    If linearly arranged warp threads are present in the textile structure, these all particularly preferably run directly next to one another and thus form a kind of “minimal structure” of the textile structure. In other words, in this preferred embodiment, there are no double-function threads whose warp thread sections run in the warp direction between two linear warp threads.
    As can already be seen in part from what has been said above, the double-function threads in the textile structure can have different profiles in sections in the warp direction, i.e. coming from the weft direction, in particular a double-function thread can:
    - are deflected by 90 ° on the longitudinal textile structure edge and then run along the textile structure edge over more than one weft row in the warp direction,
    are deflected by 180 ° on the longitudinal textile structure edge, that is to say form the adjacent weft thread row directly,
    - Cut off on the longitudinal textile structure edge, preferably after textile structure contouring according to the invention, and / or
    - are brought into a parking position in order to then be re-entered into the textile structure at a later point in time, advantageously in the weft direction. In the present case, “park position” is preferably understood to mean that a double-function thread is clamped and held on the textile structure edge by a gripper before it is re-inserted into the textile structure in the weft direction after a certain period in which the textile structure has been built up.
    Overall, very variable end contours of the textile structure which are adapted to the different requirements can thus be produced, to which the different course options of the double-function threads can make a significant contribution.
    The double-function threads can either be introduced (entering) and / or discharged (departing) from the weft direction or from the warp direction in the textile structure. In the event of entry in the warp direction, an embodiment which is currently considered expedient provides for double-function threads to be inserted in the area of one of the two textile structure edges. If, for example, a double-function thread is fed from above together with conventional warp threads, a double-function thread on the edge in particular - preferably after passing a few rows of weft threads - can be gripped by a gripper which can be moved in the weft direction and which integrates the double-function thread into the textile structure when it is traveling in the weft direction. The free end of the double-function thread can then be held at the opposite edge of the textile structure, this warp-side holding forming a warp thread section of this double-function thread due to the subsequent further construction of the textile structure. Finally, a control gives the command to reinsert the double-function thread into the textile structure in the weft direction, whereby a new weft thread section of the double-function thread is created. On the opposite side of the textile structure, for example, another gripper can grip the free end of the double-function thread. Alternatively, the gripper travels through or over the textile structure.
    In one embodiment of the textile structure according to the invention, it is provided that there are no conventional weft threads in the textile structure. As is known, such weft threads only always run in the weft thread direction and are only deflected from one weft thread row to the next by the textile structure being transported forward by one weft thread row and then the weft thread being passed through the textile structure in the opposite direction. Alternatively, conventional weft threads are also integrated into the textile structure according to the invention.
    CH 710 063 B1 [0031] The invention also relates to a device for producing a textile structure, in particular a textile structure as described above. The device according to the invention has a feed device for double-function threads, which can guide the double-function threads both in the warp direction and in the weft direction. Advantageously, a respective feed device is also provided for warp threads running in the warp direction and / or weft threads running in the weft direction and / or for stitch threads.
    The device according to the invention preferably also comprises the machine elements which are usually available for the production of knitted fabrics, laid fabrics, knitted fabrics and fabrics and which are known to the person skilled in the art, for example in the case of a weaving machine, the presentation and take-off devices, the shedding device, the weaving drawer, the control, etc. ,
    An advantageous embodiment of the invention provides that at least one thread guide is provided for guiding at least one double-function thread. Preferably, the thread guide for integrating the associated double function thread can be positioned in the warp direction of the textile structure, while for integrating the associated double function thread in the weft direction of the textile structure it is designed to be movable in the weft direction.
    In a further development of the device, a gripping device is provided, by means of which the at least one thread guide can be gripped and clamped in order to move the thread guide and thus the double-function thread in the weft direction.
    Furthermore, it is advantageous if the at least one thread guide is designed to be tiltable at least during its movement in the weft direction with respect to the warp direction. In this way, an excessively large exit angle of the double-function thread relative to the exit edge of the thread guide can be avoided, so that an otherwise excessive friction at this point can be prevented.
    [0036] According to an advantageous embodiment, the at least one thread guide on the long side of the textile structure can be moved into a parking position. The double function thread can be parked there until it is reintroduced into the textile structure.
    Alternatively or additionally, the at least one thread guide is designed in such a way that it can guide the assigned double-function thread on the outer edge of the textile structure over several rows of weft threads. In this case, the resulting edge-side warp thread section of this double-function thread is incorporated into the textile structure by deflected weft threads or weft thread sections of other double-function threads or by another warp thread and / or warp thread sections of other double-function threads also running on the edge.
    The invention also relates to a method for producing a textile structure, in particular a textile structure as described above by means of a device as described above. In accordance with the method according to the invention, the textile structure is built up at least from double-function threads, which are integrated into the textile structure both in the warp direction and in the weft direction with the formation of warp and weft thread sections. In addition there can be warp threads which are stretched in the warp direction and / or weft threads which are bound in the weft direction and / or stitch threads which are used in particular to fix the stretched, undulated double-function threads.

    CH 710 063 B1 [0040] FIG. 1 shows a first embodiment of a textile structure 1. This textile structure 1 is explained by way of example using only seven threads, a commercial textile structure usually, of course, consisting of significantly more threads. The textile structure 1 has four warp threads 2 running parallel and directly next to one another in the warp direction KR. Furthermore, three double-function threads 3, 4, 5 are integrated into the textile structure 1, which run in warp thread sections 3a, 4a, 5a in the warp direction KR and in weft thread sections 3b, 4b, 5b in the weft direction SR. The length of the respective warp thread sections 3a, 4a, 5a in the warp direction KR and the respective weft thread sections 3b, 4b, 5b in the weft direction SR are of different lengths in the present case, as can also be seen from the explanations below.
    The textile structure 1 according to FIG. 1 can be designed as a scrim, knitted fabric, knitted fabric or fabric. In the case of a scrim, knitted fabric or knitted fabric, for the sake of simplicity, no stitch threads are shown, which then serve in particular to fix the double-function threads and any warp and weft threads that may be present. Such a representation of stitch threads is shown in FIG. 5.
    Coming back to FIG. 1, the double-function thread 3 is inserted into the textile structure 1 in the weft direction SR at its lower left picture edge and initially runs as a weft thread section 3b in the weft direction SR. After two direct deflections at the two longitudinal edges of the textile structure 1, the double function thread 3 runs as a warp thread section 3a in the warp direction KR on the right textile structure edge, passing two weft thread rows, which are formed by two weft thread sections 4a of the double function thread 4, before it is deflected again by 90 ° and passes into a weft section 3b. On its way along the right edge of the textile structure 1, the said warp thread section 3a crosses or “overtakes” the double function thread 4. Such intersecting courses of the double function threads at the edges of the textile structure 1 can be found in many places of the textile structure 1. The rest is the rest The course of the double function thread 3 can be seen directly in FIG. 1. In particular, it can be seen that the double functional thread 3 again leaves the textile structure 1 in the weft direction SR at the upper left edge of the image.
    1, but entered in the warp direction, double function thread 4 crosses here as warp thread section 4a three weft rows before it is deflected by 90 ° to the right and as weft section 4b in the weft direction SR, first the double function thread 5 and then crosses the four warp threads 2. The resulting textile structure width in this section is designated by b1 in FIG. 1. Subsequently, the double function thread 4 is deflected by 180 ° on the right edge of the textile structure 1 and then again crosses the warp threads 2 and the warp thread section 5a of the double function thread 5 as weft thread section 4b. With this direct deflection by 180 ° at the textile structure edge, there is between the two successive ones Weft sections 4b no warp section 4a. Warp thread sections are referred to in the context of the present invention when a double function thread runs over more than one weft thread row in the warp direction KR.
    After the aforementioned crossing of the double function thread 5, the double function thread 4 is again deflected by 90 °. This results in the width b2 at this point of the textile structure 1, which is one row of warp threads narrower than the width b1.
    The double function thread 5 in FIG. 1 runs from the lower edge of the picture first as a warp thread section 5a, with the crossing of 12 weft rows, in warp direction KR, before it is deflected by 90 ° to the right and merges into a weft thread section 5b, which the four warp threads 2 crosses. This weft thread section 5b is again deflected by 90 °, this time in the warp direction KR, on the right edge of the textile structure 1 and then runs, crossing a weft thread row, as a short warp thread section 5a in the warp direction KR. It is then deflected again by 90 ° and then crosses the four warp threads 2. When the four warp threads 2 are first crossed, the textile structure 1 has the width b2, while in the next row of weft threads it only has the width b3, since all double-function threads are on extreme left warp thread 2 can be deflected by 90 °.
    The textile structure 1 thus has a non-constant width, which is realized by the course of the double-function threads 3, 4, 5 according to the invention. In the further course of the textile structure 1 - on the one hand due to the different weft length of the double functional threads 3, 4, 5, i.e. the different lengths of their warp thread sections 3b, 4b, 5b, and on the other hand by taking over the warp thread function of the warp thread sections 4a, 5a, 6a - the width the textile structure 1 gradually from b3 to b2 and finally to b1.
    According to the also schematically illustrated embodiment of FIG. 2, five double-function threads 3, 4, 5, 6, 7 are provided, of which the double-function thread 3 in the weft direction SR and the other double-function threads 4, 5, 6, 7 in the warp direction KR in the textile structure 1 can be introduced. The double-function threads 4, 5 are fed on the left side of two warp threads 2 and the double-function threads 6, 7 from their right side. As in the embodiment according to FIG. 1, the double-function threads 3, 4, 5, 6, 7 each have warp thread sections 3a, 4a, 5a, 6a and 7a and weft thread sections 3b, 4b, 5b, 6b and 7b, the respective lengths in the warp direction KR and in the weft direction SR are not uniformly long. According to the exemplary embodiment in FIG. 2, a narrowing on both sides in the warp direction KR is realized (from the width b1 to b2, b3, and b4 to b5) and then widens again (from the width b5 to b4, b3 and b2 to b1) , Otherwise, all features are found in the textile structure according to FIG. 2 as in the textile structure according to FIG. 1, so that further explanations are not necessary.
    CH 710 063 B1 The textile structure 1 according to the exemplary embodiment shown in FIG. 3 again consists of two warp threads 2 running in the warp direction KR and five double-function threads 3, 4, 5, 6, 7. The entry and the initial arrangement of the double-function threads 3 , 4, 5, 6, 7 corresponds to the exemplary embodiment in FIG. 2. However, as can be seen in FIG. 3, the width of the textile structure 1 gradually decreases in the warp direction KR from the width b1 to the width b5. The designation and the course of the double-function threads 3, 4, 5, 6, 7, namely on the one hand as warp thread sections 3a, 4a, 5a, 6a and 7a and on the other hand as weft thread sections 3b, 4b, 5b, 6b and 7b, corresponds to the exemplary embodiments according to 1 and 2.
    In all of the exemplary embodiments in FIGS. 1-3, a textile structure 1 with a constant basis weight and a reinforcement geometry that conforms to the final shape is obtained.
    By introducing the double-function threads 4, 5 or 5, 6, 7 in the warp direction according to FIGS. 1-3, the width of the textile structure 1 increases with each double-function thread 4, 5, 6, 7 by one row of warp threads.
    In the exemplary embodiments according to FIGS. 1-3, the weft thread sections 3b, 4b, 5b, 6b, 7b always cross the textile structure 1 completely in accordance with the respective local width (b1-b5). However, it is also possible for the weft thread sections 3b, 4b, 5b, 6b, 7b of the double function threads 3, 4, 5, 6, 7 to cross only part of the local width of the textile structure 1 and, for example, between two warp threads 2 or between a warp thread 2 and a warp thread section of a double-function thread or between two warp thread sections of two double-function threads are deflected in the warp direction or removed from the textile structure (in which case usually no uniform basis weight of the textile structure 1 is obtained).
    4 shows a further embodiment, in which six double-function threads 3, 4, 5, 6, 7, 8 are guided such that an opening 20 is present in the textile structure 1, which is only shown in part. For this purpose, the warp and weft sections 3a, 3b, 4a, 4b, 5a, 5b, 6a, 6b, 7a, 7b, 8a, 8b (not all are provided with reference numerals for the sake of simplicity) are guided accordingly. The further integration of the opening 20 in the textile structure 1 is only indicated by the weft thread section 3b of the double-function thread 3 indicated above the opening 20. Such an integration is realized in particular upstream and downstream of the opening 20 (seen in the warp direction KR), for example by weft threads or by weft thread sections from others and / or the double-function threads shown.
    In the figures discussed so far, a textile structure 1 is shown, the binding of which was only briefly explained. If the textile structure 1 is a scrim, knitted fabric or knitted fabric, its reinforcing structure is formed from the warp threads 2 (FIGS. 1-3) and the double-function threads (FIGS. 1-4), which are formed by stitch threads 9A, 9B, as shown in FIG. 5 is shown schematically using the example of a scrim or knitted fabric to be held together. The stitch threads 9A, 9B, which are fed in, for example, via thread guides or thread bars, fix the double-function threads 3, 4, 5, 6, 7, 8 and possibly also warp threads 2 and / or weft threads, which are usually stretched and not undulated, with their stitches run. These mesh threads 9A, 9B make no significant contribution to reinforcing the textile structure.
    In Fig. 6a in plan view and in Fig. 6b in front view (cut along A-A of Fig. 6a), a known device 110 is shown, with which a known textile structure 101 can be produced. A plurality of warp thread tubes 111 are attached next to one another on a holder 112 and aligned in the warp direction KR, a warp thread 102 being threaded through each warp thread tube 111. A weft thread 122 is guided over a deflection roller 113 through a tubular weft thread guide 115 which oscillates back and forth in the weft direction SR by a drive device, not shown. The known device 110 is designed as a type of laying machine, by means of which a placement and arrangement of the weft threads 122 and the warp threads 102 can be achieved which is adapted to the respective textile production process (weaving, knitting, knitting). The arrangement of the aforementioned threads in the textile structure 101 is then fixed in particular by means of mesh threads and / or gluing (not shown in each case).
    7a and 7b, a device 10 according to the invention is shown, in which a double function thread 3 is integrated schematically and by way of example into a textile structure 1, the double function thread 3 in sections in the warp direction KR as the warp thread section 3a and in sections in the weft direction SR as the weft thread section 3b is guided and crosses warp threads 2 over the entire width of the textile structure 1. The warp threads 2 are in turn - as in the known device 110 of FIG. 6 - guided in warp thread tubes 11, which are attached to a holder 12, which together form a feed device 11, 12 for the warp threads 2.
    To integrate the double function thread 3 into the textile structure 1, a feed device 14 is provided, which comprises a gripping device 16 and a carriage 17 which can be moved in the weft direction SR and on which the gripping device 16 is arranged so as to be extendable. To introduce the double-function thread 3 into the textile structure 1, if necessary, it is first guided around a deflection roller 13 and into a tubular thread guide 15 which is aligned in the warp direction KR and which is designed to be changeable in the weft direction SR in the region of the holder 12. For this purpose, the thread guide 15 is gripped by the gripping device 16 and the carriage 16 moves in the weft direction in order to integrate the double function thread 3 in the next section of the textile structure 1 as a weft thread section and to add it to the previously formed textile structure 1.
    As can be seen from FIG. 7a, in addition to the double functional thread 3, further weft threads 22 are provided in the textile structure 1. These can be conventional weft threads, which therefore do not have a double function, or
    CH 710 063 B1 also weft sections of other double-function threads, which are not shown here, however, since the device and method according to the invention are explained here using the single double-function thread 3.
    8a-8e different steps of the method of the thread guide 15 by means of the feed device 14 are shown. 8a, the carriage 17 is moved such that it is located opposite the thread guide 15. The gripping device 16 is then extended so that the thread guide 15 e.g. is located between two jaws 16a of the gripping device (FIG. 8b), which then move towards one another in accordance with FIG. 8c in order to grip and clamp the thread guide 15. Subsequently, the gripping device 16 is moved back to the carriage 17 (FIG. 8d), which then moves in the weft direction SR according to FIG. 8e and in the process takes the gripping device 16 and thus also the thread guide 15 together with the double-function thread 3.
    8a-8e the deflection of a double-function thread 3 from a warp thread section 3a into a weft thread section 3b is shown. When a double-function thread 3 is deflected from a weft thread section 3b into a warp thread section 3a, the sequence of the steps takes place in reverse order, i.e. following a travel of the carriage 17 in the weft direction SR, the thread guide 15 together with the double function thread 3 is deposited in a fixed position, in particular on an edge of the textile structure 1, the double function thread 3 - with the textile structure 1 now being further built up in the warp direction - immediately runs along the edge of the textile structure 1 and thus becomes part of the textile structure 1, in order to then cross the textile structure 1 again in the opposite direction as a weft thread section 3b.
    Instead of running along the edge of the textile structure 1, the double-function thread 3 can also be brought into a parking position on the edge of the textile structure in one or more sections, so that it does not become part of the textile structure.
    The gripping and clamping can be realized in the gripping device 16 via mechanical, pneumatic or (electromagnetic means).
    7 and 8, for the sake of simplicity, no feed devices for stitch threads 9A, 9B (see FIG. 5) are shown, which include thread guides or thread bars, for example.
    9a and 9b, a variant of the device according to FIGS. 7a and 7b is shown, in which the feed device 14, i.e. the slide 17, together with the gripping device 16 and thus also the thread guide 15, is designed to be tiltable perpendicular to the plane spanned by the textile structure 1, so that the double-function thread 3 on the trailing edge of the thread guide 15 is not damaged by friction. 9a shows a tilted alignment to the left; in the case of an entry in the opposite direction, the feed device 14 is advantageously tilted to the right.
    1-5, the textile structure 1 is a scrim, knitted fabric or knitted fabric. The devices according to FIGS. 7-9 are also designed for the production of a scrim, knitted fabric or knitted fabric. Alternatively, the textile structure 1 according to the invention can be easily implemented as a fabric. The necessary mechanical and procedural adjustments are in the technical skill. For example, in the case of a weaving machine, the double-function threads can be guided in the weft direction by a known gripper, which does not immediately shoot the double-function thread into the fabric again, but initially leaves it on the edge of the fabric and at a later point in time again the double-function thread into the fabric through a shed shoots. A gripper can be provided for each double-function thread; it is also possible to use a hook alternately for different double-function threads. The above considerations apply accordingly when the double functional threads are introduced in the weft direction.
    The above explanations clarify that the basis weight of a textile structure can be specifically adjusted in all areas by means of the invention. In particular, it can be achieved that the basis weight can be set constantly in all areas.
    The aforementioned exemplary embodiments are not to be interpreted as restrictive. Rather, modifications are easily possible within the claims. For example, it is possible to construct a textile structure 1 according to the invention only from double-function threads and, if necessary, fixing mesh threads. Textile structures with double-function threads and warp threads and / or weft threads can also be realized, mesh threads also preferably being provided here for fixing in the case of laid fabrics, knitted fabrics and knitted fabrics.
