Definitions

  • the invention relates to a fabric with a plurality of linear and parallel warp threads and a plurality of linear and parallel weft threads.
  • the invention relates to a corresponding method and a corresponding device.
  • Fabrics have been known for thousands of years, using a wide variety of techniques. Warp threads running in the longitudinal direction are usually clamped next to one another, with a part of the warp threads being raised and a part being lowered in order to allow weft insertion perpendicular to the warp threads through the shed thus formed. Common to almost all known weaving techniques is that the outer sides of the fabrics are limited to linear contours in the warp direction. This means that the fabrics have fixed widths.
  • form-fitting fabrics can be produced with the help of bobbin weaving technology.
  • individual warp threads are not bound by the weft. These warp threads run "empty", but there is a large waste.
  • V-reeds which change the local warp density in the warp direction to realize width variations of the fabric over the fabric length.
  • this method is only used in narrow weaving.
  • Another disadvantage is that only inhomogeneous fabrics can be manufactured and the flexibility of this method is extremely low.
  • Another disadvantage is the increased and thus inefficient use of material and the arrangement of the reinforcing material, which is not always in accordance with the force flow.
  • the JPH06272134 A can also not help to provide a form-fitting fabric.
  • the JPH06272134 A describes a method for producing a woven fabric from glass fibers, in which first leno threads are used to bind the warp threads on the long sides of the woven fabric in a first region. Furthermore, additional second leno threads are woven into a second region of the fabric that is still further out. The fabric is cut between these two areas along a line running in the warp direction, the cut area being cut waste and the resulting fabric being delimited by the first leno threads.
  • the outside contour of the fabric is formed by at least one additional warp thread that deviates from the straight warp direction (0 ° direction) and / or does not run continuously, the additional warp thread or threads being made of high-performance material, for example in the form of glass fibers, ceramic fibers, carbon fibers , Steel fibers or wire.
  • the advantages of the invention are in particular that almost any tissue contours in the longitudinal direction of the tissue, i.e. in the stretched warp direction can be realized.
  • fabrics can be designed according to the required semi-finished product geometries and directly, i.e. can be produced in one operation without waste.
  • the fiber material used can be used extremely efficiently, while minimizing or completely avoiding waste.
  • process stages can be saved and additional assembly stages can be largely avoided.
  • the method according to the invention with the features of claim 10 can also be implemented relatively easily by means of modification and further development of known weaving technologies.
  • the fabrics according to the invention are made with all textile or textile processable materials and in particular also with high-performance materials such as Can be produced in the form of glass fibers, carbon fibers, ceramic fibers, steel fibers, wire, thermoplastic materials, etc.
  • high-performance materials such as Can be produced in the form of glass fibers, carbon fibers, ceramic fibers, steel fibers, wire, thermoplastic materials, etc.
  • a fabric of linear and parallel warp and weft threads is present and the shaping by additional warp threads - at least in one or more Sections along the fabric on its longitudinal edges - is realized.
  • a corresponding device is also part of the invention.
  • the invention allows any tissue contours to be obtained.
  • the contour can run at any angle between -90 ° and 90 °. Both angular and curved contours can be realized. Furthermore, both external and internal edges can be created. This enables a partial division of the tissue in the longitudinal direction into two or more parts. This final contour or shape design can also be used to form force application zones. Asymmetrical contours can also be realized.
  • the linear and parallel warp threads and the linear and parallel weft threads form a first warp region with a constant width in the stretched warp direction (0 ° direction).
  • the width of this first warp region corresponds to the minimum fabric width that can be realized.
  • at least one additional warp thread preferably at least one thread group consisting of a plurality of additional warp threads running side by side (which then form a warp thread family), is present in order to define a second warp region which adjoins a long side of the first warp region.
  • the at least one additional warp thread or the at least one thread group forms at least in one section along the fabric the maximum width of the second warp region which is offset in the weft direction from the first warp region.
  • the second warp region forms a lateral nonlinear contour region of the fabric, that is to say in the longitudinal direction, that is to say the warp direction, of the fabric, at least in sections, that is to say in one or more sections that follow one another in the warp direction.
  • “Section by section” here means that the second warp area in its Width fluctuates (this is the reason for the non-linear contour progression on the longitudinal fabric edge or edges) and the maximum width of the second warp region is only realized in sections by one or more additional warp threads.
  • the width of the second warp region can also be zero in sections, that is, if the additional warp thread or threads in one or more sections are immersed in the warp direction in the first warp region.
  • a plurality of thread groups each comprising a plurality of additional warp threads running next to one another, are provided in such a second warp region.
  • These multiple thread groups preferably overlap at least in sections in the warp direction. In this way, different force introduction zones in the second warp area can be realized in particular.
  • such a second warp region is present on both longitudinal fabric edges.
  • the additional warp threads run within a thread group, preferably within each of the thread groups, with the same distance from one another in each case in the weft direction.
  • Such an embodiment can be achieved particularly easily by means of a modification of the so-called open reed weave technology (weaving with an open reed), which is explained in more detail below.
  • the distances of the thread groups to one another are preferably variably adjustable in the weft direction and / or in the warp direction.
  • the fabric according to the invention has variable distances between additional warp threads in the weft direction - also within a thread group - these sections of variable distances when the additional warp threads run in the stretched warp direction (0 ° direction) and / or in the stretched warp direction (K ) deviating Direction and / or if they are not continuous, may be present.
  • At least one said second warp region with at least one said thread group, each with a plurality of additional warp threads, is arranged on both sides of the first warp region. This means that almost any form-fitting tissue contours can be realized.
  • the threads of the two second warp areas are bound by the weft thread in accordance with the desired contour.
  • the fabric according to the invention is given a firm structure in particular if at least one and preferably several additional warp threads of at least one thread group cut at least one and preferably several warp threads of the first warp region. In these overlap areas there is therefore a high warp density, which contributes to the higher fabric resilience.
  • the lateral limitation of the fabric can be realized in different ways.
  • the weft threads have a constant length, the protruding threads being cut off subsequently.
  • bobbin protection technology is used, in which the weft thread is deflected at the fabric edge.
  • the rapier weaving technique is used, the weft thread having a defined length while realizing a variable rapier stroke. With the latter two methods, a contoured fabric with a firm edge can be produced without loss of material.
  • all other weft insertion methods in which the stroke can be designed variably can also be used.
  • variant 2 at least some of the additional warp threads delimiting the fabric are interrupted in the weaving direction and then, ie after several defined shot cycles, resumed in the tissue. In this way too, lateral contouring (width contour) of the fabric can be achieved.
  • variant 3 Another variant of the invention (also referred to below as variant 3) is characterized in that one or more additional warp threads are integrated into the fabric according to the desired width contour.
  • at least one additional warp thread is designed as an adhesive thread which is woven into the fabric and forms an adhesive connection with the warp and weft threads.
  • the at least one additional warp thread provided for width contouring consists of thermoplastic material, which is melted onto the fabric.
  • the fabric is cut along the said at least one additional warp thread to the final contour.
  • the fabric is particularly preferably produced using the principles of the so-called open reed weave, which is used, for example, in the DE 10 2010 007 048 A1 is described.
  • additional thread weft effects are achieved during the manufacture of a rectangular fabric, in that at least one effect thread is displaced from an upwardly open reed gap by means of an offset device which can be moved back and forth in the weft direction and is immersed in another open reed gap of the reed. Then a weft thread is inserted. If the effect thread is to be placed again in another direction in the weft direction, it is again transferred from one reed gap to another reed gap before the next weft insertion.
  • the warp thread offset device is designed in such a way that - for the production of at least one second warp region (see above) - instead of an effect thread always placed within the rectangular fabric, at least one additional warp thread is now placed in sections outside of this rectangle and for an outside contouring of the fabric - at least in sections - is used.
  • the warp thread offset device can thus be varied back and forth in the weft direction beyond the edge regions of the fabric produced from linear warp and weft threads in accordance with the desired final contour of the fabric.
  • a second warp region can be produced on each longitudinal side of the fabric, which has a contour that deviates from the stretched warp direction.
  • a plurality of thread groups each with a plurality of additional warp threads running side by side, are to be provided in a second warp region
  • a plurality of warp thread offset devices arranged one behind the other in the longitudinal or warp direction of the warp are preferably used, as indicated above. In this way it can also be achieved that the several thread groups overlap in sections.
  • the additional warp threads which can be displaced by means of the warp thread offset device (s) can be arranged both in the warp direction and also diagonally or deviating from the warp direction.
  • the configuration of the open reed also makes it easy to implement that at least one additional warp thread of a second warp region cuts at least one warp thread of the first warp region.
  • a fabric according to variant 3 can also be realized by further developing the open reed weave by integrating one or more additional warp threads in the fabric according to the desired final width contour.
  • these additional threads consist of thermoplastic material which is melted, or are designed, for example, as adhesive threads. The cut is then made along the (outermost) additional warp threads in order to obtain the desired shape of the fabric.
  • This additional warp thread can also be designed as a marker thread (for example colored or metallic) and can be used to control the cut.
  • the Figure 1 shows a fabric 1 according to the invention in plan view.
  • the fabric 1 has a plurality of linear and parallel warp threads 2 and a plurality of linear and parallel weft threads 3.

Also in the exemplary embodiment shown according to FIG Figure 1 It is provided that the distance from adjacent additional warp threads 5, 6 is the same as the distance from adjacent warp threads 2. However, this is not necessarily the case, but depends on the configuration of the spacings of the warp thread offset device and its thread assignment.
  • the additional warp threads 5, 6 have a course deviating from the stretched warp direction K (0 ° direction).
  • the additional warp threads 5, 6 bend obliquely inwards (section 21) after a section 20 running in the warp direction K, in turn run there linearly in the stretched warp direction K (section 22) until they each bend outwards at an angle (Section 23) to then align with the original direction of Section 20 (Section 24).
  • the additional warp threads 5, 6 run differently from the stretched warp direction K.
  • the first warp region 4 is therefore defined in that only linear and parallel warp threads 2 are present in it, while only additional warp threads 5, 6 run in the second warp regions 10, 11.
  • the additional warp threads 5, 6 do not run exclusively in the second warp regions 10, 11, but also in sections in the first warp region 4.
  • the courses, the number, the distances, the materials etc. of the additional warp threads 5, 6 in the Figure 1 are exemplary.
  • Other gradients and thus other contours can easily be realized, for example contours with any angular course between -90 ° and 90 °, angular and curved contours, outside and inside edges as well as asymmetrical contours.
  • 0 ° denotes the (stretched) warp direction K and 90 ° the weft direction S.
  • the contour or shape-appropriate design can also be used to form force application zones; according to the Figure 1 be present in all sections 20-24.

  • the additional warp threads 5, 7 of the two thread groups 12, 14 do not intersect, but on the left fabric edge in the two sections 25 and 26 due to the different radii of the arc.
  • the two thread groups 12, 14 again run essentially parallel.
  • the course of the additional warp threads 6 on the right fabric edge in sections 25, 26 corresponds to the non-linear course in sections 21, 23 of the right fabric edge in FIG Fig. 1 .
  • the fabric 1 according to the Figure 3 is the contour analogous to the fabrics 1 according to the Figures 1 and 2 realized.
  • the weft thread 3 is not inserted with a constant length, but in a length that is appropriate for the needs.

  • FIG. 5 a further embodiment of the invention is shown (also referred to above as "variant 2").
  • Positionable additional warp threads 8 are used there, which were specifically switched off from the weaving process and reinserted into this.
  • these additional warp threads 8 - depending on the weaving progress - are excluded from the weaving process by cutting.
  • the outermost additional warp thread 8 is first cut through in the second warp region 10, then the adjacent additional warp thread in the further weaving process, etc.
  • the additional warp threads to be reintroduced in the later weaving process are stored outside the fabric (“temporarily stored”) and inserted again at the intended time.

  • the additional warp threads 9 being designed as adhesive threads, marker threads or as threads made of a thermoplastic material.
  • the additional warp thread (s) 9 (several such additional warp threads 9 can be provided side by side) into the warp and weft threads 2, 3 existing fabric 1 integrated according to the desired long side contour.
  • the additional warp threads 9 in the sections 30 form a contour course of the fabric 1, which (except for the smallest lengths in the region of the deflection on the fabric edges) over the entire fabric section of the Fig. 6 deviates from the stretched warp direction K.
  • the excess weft threads 2 are then cut off.

  • individual warp threads can be specifically engaged or excluded from the weaving process. This makes it possible to change the width of the fabric without changing the local warp density - in contrast to using a V-reed.
  • individual warp threads (exemplary embodiments according to FIG Figures 1-4 ) can be arranged according to requirements at almost any angle (outside the 0 ° position). In this way, tissue that is suitable for force flow, local force application zones and tissue with gradient properties can be realized.
  • Such force introduction zones can also be realized, for example, by additional warp threads, which (also) determine the non-linear contours that deviate from the stretched warp direction or via the fabric consisting of linear warp and weft threads, for example from one fabric longitudinal side to the other and possibly again - at least partially - run back.

It is common to all fabrics according to the invention that they have non-linear contours which deviate from the stretched warp direction K and which are achieved by at least one additional warp thread.
  • variable weft lengths can also be realized, which enables a weft length adapted to the local fabric width. This eliminates the need for subsequent cutting and shot waste is avoided.
  • the invention realizes an automatically producible form-fitting fabric with the best possible use of the fiber material to be used for the production of near-net-shape tissue with reinforcing material arranged according to requirements.
  • the entire system is highly variable and allows absolute flexibility with regard to the contours that can be achieved and the arrangement of the reinforcement material.
