BRIEF DESCRIPTION OF THE DRAWINGS
[0057] In the following, preferred embodiments of the textile fabric according to the invention are described with reference to the attached figures.

DESCRIPTION OF EXAMPLE EMBODIMENTS
[0066]
[0067] The textile fabric 10 has a first thread group 20 with a plurality of longitudinal threads 1k, . . . , mk, which run in the longitudinal direction of the textile fabric 10. The longitudinal direction of the textile fabric 10 corresponds to a direction along the k-axis of the coordinate system shown in
[0068] In addition, the textile fabric 10 has a second thread group 30 with a plurality of transverse threads 1s, . . . , ns running in the transverse direction. The transverse direction of the textile fabric 10 corresponds to a direction along the s-axis of the coordinate system shown in
[0069] In total, the thread groups 20, 30 form a textile fabric-body 12 which is stretched in the aforementioned longitudinal direction (k-direction) and transverse direction (s-direction).
[0070] The d-axis of the coordinate system shown in
[0071] The textile fabric 10 or the textile fabric-body 12 is preferably a woven fabric. Accordingly, the longitudinal threads 1k, . . . , mk form warp threads of the fabric, and the transverse threads 1s, . . . , ns correspond to a weft thread s of the woven fabric-body 12, which is laid into the fabric at the correspondingly designated positions such that the transverse threads/weft threads 1s, . . . , ns are formed.
[0072] Particularly preferably, the textile fabric 10 according to the invention is a woven strap that extends in the aforementioned longitudinal direction.
[0073] The strap is preferably produced on a needle strap weaving machine.
[0074]
[0075] After the weft insertion needle SEN has completely passed through the formed shed and is reaching the corresponding opposite end of the shed with the weft thread s as a thread loop, a stitch is formed there by a latch needle not shown in
[0076] For example, the latch needle can form the strap edge by [0077] i. forming a stitch from the weft thread loop, [0078] ii. tying off the thread loop formed from the weft thread s via a catch thread that forms the stitch, [0079] iii. forming a stitch from the weft thread s, which is passed through as a thread loop, and at least one catch thread fed in, or [0080] iv. forming a stitch from the weft thread s, which is passed through as a thread loop, at least one catch thread fed in and a blocking thread fed in.
[0081] Variant iii. is preferred, whereby a single catch thread is used.
[0082] The strap edge formed by the latch needle is therefore a knitted selvedge due to the technology.
[0083] At the end of the formed shed facing the weft insertion needle SEN, the strap edge is formed there by the shed change that takes place after the weft insertion needle SEN has returned. The strap edge facing the weft insertion needle SEN is therefore a selvedge.
[0084] It is clear from the above explanation that each of the weft threads 1s, . . . , ns shown in
[0085] The textile fabric 10 according to the invention is not limited to the configuration as a strap and also not to the edges, selvedge and/or knitted selvedge, as explained.
[0086] For example, the textile fabric 10 can be a large-area broad-fabric that is not produced with the needle strap weaving machine, but with a different type of automatic weaving machine, in which, for example, the direction of an insertion of the weft thread changes and other types of edges also result.
[0087] The strap (or the tube, which will be explained below) can also be produced using a different type of weaving machine.
[0088] The longitudinal threads or warp threads 1k, . . . , mk of the textile fabric 10 according to the invention are linked or combined or interwoven with the corresponding transverse threads or weft threads 1s, . . . , ns in such a way that force redirection structures 40 are formed running in the transverse direction or in the direction of the s-axis of the coordinate system. The force redirection structures 40 run completely across the entire textile fabric 10 in the aforementioned transverse direction.
[0089] The force redirection structures 40 are repeated in the longitudinal direction shown in
[0090] Alternatively, the force redirection structures 40 can be formed with a preferably regular offset V on one of the sides, the top side or the bottom side.
[0091] The offset shown or the corresponding distance is, for example, 3 mm to 8 mm, particularly preferably 5 mm.
[0092] The force redirection structures 40 have the effect and nature that when force is applied to the fabric-body 12 from normal direction, which corresponds to the d-axis shown in
[0093] The textile fabric 10 offers good protection for a sheathed object, such as a cable or a drive accumulator in a motor vehicle, thanks to the force deflection.
[0094] With reference to
[0095]
[0096] The four longitudinal threads or warp threads 1k, . . . , 4k shown in
[0097] The warp threads shown in columns 9 and 10 in
[0098] In addition to the warp threads, the weft threads explained with reference to
[0099]
[0100]
[0101] Preferably, the warp thread 1k or the warp thread 3k forms a first longitudinal thread or warp thread, which runs in the positive d-direction above the transverse threads or weft threads 5s and 1s according to the fabric section from
[0102] The weft thread 6s (line 6) located in the longitudinal direction (k-axis) between these weft threads 5s and 1s lies on the first warp thread 1k, 3k. If both warp threads 1k, 3k run above the two lower weft threads 5s and 1s, the weft thread 6s therefore lies on both warp threads 1k, 3k.
[0103] As can be seen in
[0104] At the same time, the upper weft thread 6s corresponds to a tip of the corresponding force redirection structure 40. Only the warp thread 2k runs over the upper weft thread 6s according to the fabric section in
[0105] The warp thread 2k is preferably the only warp thread in the warp-rapport shown that has this pathway above the upper weft thread 6s. In relation to the adjacent weft threads 5s, 1s, the pathway of the warp thread 2k is selected in such a way that-unlike the adjacent warp threads 1k, 3kit runs below these weft threads 5s, 1s. In this regard, cf.
[0106] Adjacent to the weft threads 5s, 1s are the weft threads 4s (line 4) and 2s (line 8), which form two further lower weft threads 4s, 2s. The weft threads 5s, 6s, 1s (rows 5 to 7) are located longitudinally between the two further lower weft threads 4s, 2s.
[0107] The warp threads 1k, 3k run underneath these further lower weft threads 4s, 2s according to the fabric section in
[0108] The remaining warp thread 4k belonging to the same warp-rapport runs over the two further lower weft threads 4s, 2s according to
[0109] The star drawn in
[0110] The textile fabric 10 shown in
[0111]
[0112] If an external force acts on the textile fabric 10 along the shown thickness direction (d-axis), the force redirection structures 40 develop the protective effect already mentioned by redirecting the external force in the longitudinal direction (k-axis).
[0113] The external force is redirected in the longitudinal direction by the fact that, under force application, of the force redirection structures 40 by the external force, the upper weft thread 6s is moved in the direction of the two lower weft threads 5s, 1s, as a result of which the warp threads 1k, 3k (first longitudinal thread or first longitudinal threads) are subjected to tensile stress in the longitudinal direction. The lower weft threads 5s, 1s act as bearings for the warp threads 1k, 3k.
[0114] The further, lower weft threads 4s, 2s act as bearings for the warp thread 4k, which floats below the weft threads 5s, 6s, 1s and in turn forms a support for them. If the weft threads 5s, 6s, 1s are pressed between the further, lower weft threads 4s, 2s and on the warp threads 4k, the external force is again redirected in the longitudinal direction of the textile fabric-body 12.
[0115] In
[0116] The shown strap can be used to protect smaller objects in a flat design or, for example, to sheathe electrical cables, especially high-voltage cables. In order to realize such a sheath of electrical cables, it is preferable that the weft threads 1s to 6s have material-specific properties such that they warp under thermal stress or heating in such a way that the fabric-body 12 curls around the k-axis to form the sheath.
[0117] Alternatively, the weft threads 1s to 6s can have material-specific properties such that they become more flexible/softer when heated, allowing the fabric-body 12 to be rolled up to sheathe the electrical cable. If the weft threads 1s to 6s cool down again after the electrical cable has been sheathed, the rolled-up fabric-body 12 retains its shape.
[0118] Furthermore, the weft threads 1s to 6s can have such material-specific properties that they can be bent without heating to sheathe the electrical cable and then remain dimensionally stable.
[0119] After the textile fabric-body 12 has been rolled up, the weft threads 1s to 12s lie essentially on a horizontal straight line in the d-k plane. This arrangement also applies to the tube explained below with reference to
[0120]
[0121] According to
[0122] The reed is very coarse and selected so that the warp threads of two warp-rapports, i.e. the warp threads according to columns 1 to 8 in
[0123] The textile fabric 10 described in
[0124]
[0125]
[0126] The binding pattern of the upper and lower textile fabric 10, 10 is identical to that in
[0127]
[0128] In contrast to
[0129] Lines 1 to 12 indicate the weft threads, whereby the lines with even numbers indicate the weft threads of a weft-rapport 1s, . . . , 6s in the upper textile fabric 10 and the lines with odd numbers indicate the weft threads 1s, . . . , 6s of a weft-rapport in the lower textile fabric 10.
[0130] In addition, the binding cartridge according to
[0131] From the above explanations, it results that the positive binding cartridge from
[0132] The warp threads according to columns 9 and 10 in
[0133] The upper textile fabric 10 and the lower textile fabric 10 are joined together at the selvedge and the knitted selvedge to form the closed tube. In other words, the selvedge and the knitted selvedge are produced in a manner that the textile fabrics 10, 10 are joined.
[0134] The shaft feed and the reed feed for forming the tube are identical to those in
[0135] A second preferred embodiment of the textile fabric is now described with reference to
[0136]
[0137]
[0138] The textile fabric has a first thread group consisting of longitudinal threads/warp threads and a second thread group consisting of transverse threads/weft threads. The thread groups form a corresponding fabric-body.
[0139] The longitudinal threads or warp threads 1k, . . . , mk of the textile fabric 100 according to the invention are linked or combined or interwoven with the corresponding transverse threads or weft threads 1s, . . . , ns in such a way that force redirection structures 140 are formed running in the transverse direction or in the direction of the s-axis of the coordinate system. The force redirection structures 140 run completely across the entire textile fabric 100 in the aforementioned transverse direction.
[0140] The force redirection structures 140 are repeated in the longitudinal direction shown in
[0141] Alternatively, the force redirection structures 140 can be formed with a preferably regular offset V on one of the sides, the top side or the bottom side.
[0142] The offset shown or the corresponding distance is, for example, 5 mm to 10 mm, particularly preferably 7 mm.
[0143] As in the first preferred embodiment, the force redirection structures 140 have the effect and nature that when force is applied to the textile fabric or the fabric-body, respectively from the direction of a normal, which corresponds to the d-axis shown in
[0144] The binding pattern of the textile fabric 100, leading to the force redirection structures 140 is described with reference to
[0145] Together the four longitudinal threads or warp threads 1k, . . . , 4k shown in
[0146] The warp threads shown in columns 9 and 10 in
[0147] As in the first embodiment, the textile fabric 100 can be a large-area structure (broad woven fabric) or a strap. It can also be double-woven to form a closed tube, as explained above.
[0148]
[0149] The weft thread 7s (line 7) located in the longitudinal direction (k-axis) between these weft threads 6s (line 6) and 8s (line 8) lies on the first warp thread 2k.
[0150] As can be seen in
[0151] At the same time, the upper weft thread 7s corresponds to a tip of the corresponding force redirection structure 140. Only the warp thread 4k (column 4) runs over the upper weft thread 7s according to the fabric section in
[0152] The warp thread 4k (column 4) is preferably the only warp thread in the warp-rapport shown that has this pathway above the upper weft thread 7s. In relation to the adjacent weft threads 6s, 8s, the pathway of the warp thread 4k is selected in a manner that -unlike the warp thread 2kit runs below these weft threads 6s, 8s. The warp thread 4k then floats to the adjacent force redirection structure 40 on the same side of the fabric-body, where its pathway is repeated.
[0153] Adjacent to the lower weft threads 6s, 8s are the weft threads 5s (row 5) and 9s (row 9), which form two further lower weft threads. The weft threads 6s, 7s, 8s (rows 6 to 8) are located between the two further weft threads 5s, 9s in the longitudinal direction.
[0154] The warp thread 2k runs underneath these further lower weft threads 5s, 9s according to the fabric section in
[0155] The textile fabric 100 also has four further lower weft threads 3s, 4s, 10s, 1s. The weft threads 4s, 5s, 6s, 7s, 8s, 9s, 10s are located longitudinally between the further lower weft threads 3s, 1s and the weft threads 5s, 6s, 7s, 8s, 9s are located between the further lower weft threads 4s, 10s.
[0156] The warp thread 2k runs over the further lower weft threads 4s, 10s and below the further lower weft threads 3s, 1s.
[0157] The warp thread 1k runs over the two further lower weft threads 5s, 9s according to
[0158] The remaining warp thread 3k, which belongs to the same warp-rapport, runs over the further lower weft threads 3s, 1s according to
[0159] The star drawn in
[0160] The textile fabric 10 shown in
[0161] If an external force acts on the textile fabric 100 along the shown thickness direction (d-axis), the force redirection structures 140 develop their protective effect by redirecting the external force in the longitudinal direction (k-axis).
[0162] When force is applied to the force redirection structures 140, the upper weft thread 7s is moved in the direction of the two lower weft threads 6s, 8s, as a result of which all three weft threads 6s, 7s, 8s move together further in the direction of the floating warp thread 1k. The floating warp thread 1k forms a support for the three weft threads 6s, 7s, 8s.
[0163] The further, lower weft threads 5s, 9s act as bearings. If the weft threads 6s, 7s, 8s are pressed between the further, lower weft threads 5s, 9s and onto the warp thread 1k, the external force is redirected in the longitudinal direction of the textile fabric-body 12.
[0164] The warp thread 3k floating below the weft threads 4s to 10s forms a further support for these weft threads.
[0165] As in the first embodiment, the textile fabric 100 can be used as flat protection or rolled up to e.g. sheathe a cable. Reference is made to the corresponding explanations regarding the first embodiment.
[0166] The explanations prior to the description of the figures apply to the preferred embodiments, as well.
