    Kem-braided rope
    The present invention relates to a Kem sheath rope comprising a textile core with one or more longitudinally extending Stehfäden, present in the form of a hollow braid outer sheath, and a Kem enclosing, present in the form of a hollow braid, inner sheath.
    Kem sheath ropes are known and described for example in AT 358.433B, WO 2003/27383 A, WO 2005/085518 A, DE 40 35 814 A1, US 4,312,260 A and DE 40 38 161 A.
    The problem with existing core sheathed cables is the defective connection between core and sheath. In particular, a relative displacement of core and jacket can occur when using the rope. This shift leads to disturbing thick points, a poor power transmission from the jacket into the core and the overload in the jacket, which can lead to the crack of the shell. There are several approaches to stopping this core-shell shift:
    One possibility is to use an adhesive or an adhesive tape (see, for example, DE 40 38 161 A or GB 891,741). The gluing is not durable durable, it also prevents any relative movement between the core and coat, thus leading to a stiffening of the ropes and thus to a bad Knotbarkeit.
    It is further known to make the core and sheath more in contact with each other by joining threads from the core with sheath threads or additional transverse threads (see, for example, WO 2003 / 27383A, WO 2005 / 088518A).
    The documents EP 2 239 359 A1, DE 10 2007 063 052 A1, DE 131208 C and DE 223466 C describe braiding machines in which thread changes are provided on the basis of a corresponding arrangement of the braiding bobbins in such a way that threads from the outer region of the rope (eg outer sheath) into the inner area (eg an inner sheath) and vice versa. Likewise, according to these documents, an entanglement between outer and inner threads can be provided.
    EP 2 063 018 describes a strand element with a core of silicone material, which is covered by a textile sheath. From WO 2006/055995 it is known to provide the individual elements of a rope with a reinforcement. Further prior art is disclosed in • * T15992 2 FR 334.887, US 2,600,395 A, DE 25 41 763 A and US 4,192,127 A.
    There is still a need for core sheath ropes with satisfactory performance properties, particularly as regards the stability of the core and sheath connection throughout the life of the rope.
    In addition, in core sheathed ropes, whose core consists of several longitudinally extending threads, this core has a low dimensional stability. If one mentally removes the mantle, the core disintegrates into its individual longitudinally extending threads. Thus, a power transmission from the shell to all the core forming threads can be done only insufficient, but not all threads forming the core are used to the same extent to take over load.
    The present invention provides a core sheath rope comprising a textile core with one or more stay threads extending in the longitudinal direction of the rope, an outer sheath in the form of a hollow braid, and an inner sheath surrounding the core, in the form of a hollow braid. which is characterized in that at least a part of the stationary threads of the core is individually woven into the hollow mesh of the inner shell.
    Brief description of the figures:
    FIG. 1 shows schematically the construction of a preferred embodiment of a core sheath rope according to the invention and its production.
    Figures 2 to 7 show schematically alternative embodiments of filament changes or wraps.
    Detailed Description of the Invention: For the purposes of the present invention, the term "filaments" means the filamentary components of a rope, such as a cord. To understand twisted or braided elements. A thread may consist of a plurality of adjacent elements, such. several adjacent threads, consist, with the adjacent elements over the entire rope take the same course. * "* * *" ♦ * * * * »» • * * · · • ············································································································································································
    In the following, the term "standing threads" refers to threads which, in contrast to the threads of the inner and outer sheath, extend completely in the longitudinal direction of the rope.
    According to the invention, at least a part of the standing threads of the core extending in the longitudinal direction of the rope are individually interwoven into the hollow mesh of the inner shell. As explained above, the term "thread" also encompasses a plurality of adjacent cable elements, such as e.g. a bundle of multiple, single-break, twisted threads.
    In contrast to proposals in which all standing threads of the core are braided together by the jacket or on the other hand individual standing threads have a reinforcement, but are not connected to each other, thus standing threads of the core are woven into the hollow mesh of the inner shell. This results in a better connection and integration of the core with the inner shell.
    Preferably, a part of the standing threads of the core is not woven individually into the hollow mesh of the inner shell.
    In particular, the stand threads that are not individually woven into the hollow mesh of the inner shell are preferably arranged in the center of the core.
    In this embodiment, thus standing threads of the core without connection with each other, and without being braided into the inner shell, in the center of the core before, while more threads are woven into the hollow mesh of the inner shell.
    In a further preferred embodiment of the rope according to the invention, thread changes between threads of the inner jacket and threads of the outer jacket and / or wraps between threads of the inner jacket and threads of the outer jacket are provided at certain points.
    In this variant of the present invention, it is particularly preferred if at the points of the thread change or wraps in the longitudinal direction of the rope extending bridge threads are provided around which the from inside to outside or from outside to inside changing threads of the outer shell or inner Mantels are led. 4 T15992
    Starting from the thread changes between threads of the outer shell and the inner shell described in the above-cited documents and wraps between threads of the outer shell and the inner shell are in this preferred embodiment of the invention at these points of the thread change or the wrap additional longitudinally extending Stehfäden (bridge threads) provided.
    The following possibilities are conceivable: a change of the thread from the outer jacket into the inner jacket and vice versa, wherein the thread guided from the inside to the outside and from the outside to the inside is guided around the bridge thread. - A thread of the inner shell and a thread of the outer shell are led around each other, but then continued to the original position, i. The thread of the inner shell is continued again in the inner jacket and analogous to the thread of the outer shell again in the outer shell, The bridge thread is here between the thread of the inner shell and the outer shell and is wrapped by at least one of the threads. Although in this variant the inner sheath thread and the outer sheath thread are not intertwisted directly but over the bridge thread, this embodiment is referred to as "looping" for purposes of the present invention. A wrap and a thread change, i. a thread of the inner shell and a thread of the outer shell are routed around each other as described above, but additionally change the position, i. the thread of the inner jacket is continued in the outer jacket and vice versa. The bridge thread is here between the thread of the inner shell and the outer shell and is wrapped by both threads.
    Preferably, the bridge threads are looped by the threads of the inner shell and the threads of the outer shell.
    In all cases, however, the bridge threads provided according to the invention are encompassed by both the threads of the outer jacket and the threads of the inner jacket and thus form a bridge between the outer jacket and the inner jacket. At the same time, the (load-bearing) bridge thread remains in the pulling direction, so that it contributes to the breaking load of the rope, which is primarily determined by the threads in the pulling direction. ········································. · «· * · ** * ··. t t ··· ··· * ····. ··· «·» · * ·. · * · ·· · · * · 5 T15992
    Of course, the threads of the inner sheath and the threads of the outer sheath can also be passed around the bridge thread several times and then either continued to their original position or change the position from the outside in and vice versa.
    Preferably, the bridge threads are made of the same material as the filaments of the core.
    In a further preferred embodiment, the core sheath rope according to the invention has threads with different properties.
    In particular, properties such as color, titer, type of fiber (for example monofilament, staple fiber, multifilament), fiber material (for example polyamide, aramid, HMW-PE) or construction (for example threads of various types and / or rotation) come into consideration.
    Thus, e.g. the threads, which are initially performed in the inner jacket and the threads, which are initially performed in the outer jacket, have different colors.
    As a result, the changes from the outside can be made color recognizable. Also, length markings on the rope are possible by color change. Also within the thread material of the inner shell and / or the outer shell threads with different properties, in particular colors, can be provided.
    In a further preferred embodiment, the core sheath rope according to the invention has threads with different fineness. Thus, e.g. the threads that are initially performed in the inner jacket and the threads that are initially performed in the outer jacket, different fineness (titer) have. In particular, large differences in fineness in a yarn change lead to deliberate irregularities in the rope and to different roughness.
    The core sheath cable according to the invention preferably has further standing threads running in the longitudinal direction of the rope, which are individually braided into the hollow pile element of the outer sheath. There are thus provided in the outer region of the rope further glass-carrying elements, which are also intimately connected by braiding with the threads of the shell, here the outer shell. 6 T15992
    The bridge threads and / or the standing threads of the outer jacket may be made of the same material as the standing threads of the core.
    Moreover, all materials familiar to the person skilled in the art can be selected for the rope according to the invention.
    Figure 1 shows schematically the structure of a preferred embodiment of the inventive rope 1 and its production on the basis of the possible arrangement in a circular braiding machine. For details of such a braiding machine reference is made to the above-cited prior art documents. However, the production of a rope according to the invention in which no connection is provided between the inner and outer sheath can also take place in a two-step process in which first the inner sheath is woven with braided standing threads and in a second step the outer sheath is braided.
    The rope 1 comprises a core 2 with a plurality of core threads (standing threads) 21-28. An inner jacket 4 is located around these standing threads. Furthermore, an outer jacket 3 is provided.
    Inner sheath 4 and outer sheath 3 are formed by braiding in a manner known per se, wherein the threads of the inner sheath as well as the threads of the outer sheath are intertwined with each other by means of braiding batons (not shown). In a known manner, the Hechtklöppel on Treibrädem (not shown) are arranged. For example, 12 pike beaters may be provided for the production of the inner shell, of which in each case 6 clappers in the Z direction and 6 clappers are guided in the S direction. The resulting thread paths are indicated by solid or dashed lines. The same applies to the outer jacket. By way of example only, reference numerals 41 and 42 indicate two threads of the inner jacket and reference numerals 31 and 32 indicate two threads of the outer jacket.
    According to the invention, a part of the standing threads of the core is woven individually into the hollow mesh of the inner shell. This is illustrated in FIG. 1 for the threads 21 to 26, which are woven individually into the threads (for example: 41, 42) of the inner jacket.
    The threads 21 to 26 can be made of one or more adjacent elements, such as e.g. Twisting, consist, which are fed from breakthroughs in the Treibrädem.
    Moreover, in the embodiment shown in FIG. 1, the core has two standing threads 27 and 28 which lie in the center of the core. Of course, these are at Μ »* · · · ···································

    Completion of the rope in intimate contact with the threads of the inner shell and the other Stehfäden the core, but are not interconnected and not woven into the inner shell.
    With the reference numerals 5 and 6 positions for thread changes or wraps are shown, in which, as explained above, according to a preferred variant of the present invention, threads of the outer shell change into the inner shell and vice versa and / or threads of the outer shell and threads of the inner mantle are entwined with each other. This is, as is known, achieved by appropriate positioning of two braided bobbins (not shown) on a drive wheel (not shown).
    According to the preferred embodiment of the present invention, bridge yarns 51 and 61 are now arranged at the yarn changing positions 5 and 6, in such a way that they come to lie between the threads changing from outside to inside (and vice versa) or between the threads that wrap around each other. Apparently, this is achieved by the provision of a breakthrough in responsible for the change of thread or wrapping drive wheel.
    After completion of the rope thus these bridge thread are intimately connected to the thread of the inner and the outer shell, thus ensuring an even better connection between these two elements and at the same time increase the breaking load of the rope.
    The exact manner of changing the thread or the looping now depends on the one hand on how many degrees the braided bobbins on the drive wheels of the thread changing positions 5 and 6 are routed around, as well as whether or not the mutually changing or looping threads of the outer and inner mantle are guided in opposite directions or in the same direction.
    Whether the mutually changing or looping threads of the outer and inner sheath are guided in opposite directions or the same depends on the direction of rotation of the drive wheels of the inner and the outer shell: If the drive wheels out in opposite directions, results for the mutually changing or The threads of the inner and outer mantle, which wrap around each other, lead in the same direction and vice versa.
    Some possible variants are explained with reference to FIGS. 2 to 7: ···································································.

    Therein, in each case in the area of the thread change position 6, the course of a thread (A), which is (initially) in the outer shell, with a thick dotted line and the course of a thread (I), which is (initially) in the inner shell, shown with a thick dashed line. With the arrows in the region of the inner and outer sheath respectively the direction of movement of the threads (A) and (I) on the braiding machine, namely clockwise or counterclockwise, indicated.
    FIG. 2 shows a "simple" thread change of a thread (A) coming from the outer jacket and a thread (I) coming from the inner jacket in a variant in which A and I are guided in opposite directions. Thread A changes inwards and thread I changes to the outside, whereby the threads are guided around the bridge thread B. Structurally, this is achieved in that the filaments A and I carrying braided bobbins are guided on the drive wheel of the thread changing position by 180 °.
    Figure 3 shows a wrap, i. Outer thread A and inner thread I are once passed around each other, but are then continued at the original position (i.e., A in the outer jacket and I in the inner jacket). This is achieved structurally in that the braiding bobbins carrying the threads A and I are guided on the drive wheel of the thread change position by 360 °. The bridge thread B lies in the middle of the threads A and I and is thus entwined by them.
    Figure 4 shows a loop with thread change, i. A thread A coming from the outer shell and a thread I coming from the inner shell are once again passed around each other and then change position, i. Thread A changes into the inner jacket and thread I changes into the outer jacket. In terms of design, this is achieved by guiding the braided bobbins carrying the threads A and I on the drive wheel of the thread change position by 540 ° (360 ° + additionally 180 °). The bridge thread B is again in the midst of the threads A and I and is thus entwined by these.
    FIGS. 5 to 7 show analogous embodiments to FIGS. 2 to 4, but the threads A coming from the outer jacket and the threads I coming from the inner jacket are guided in the same direction. You can see the different from the figures 2 to 4 thread courses that are recognizable in the finished rope.
    According to the invention, it is preferable if the threads of the outer jacket and the inner jacket, which change or wrap around one another, are guided in opposite directions. ♦ * * * * »*· * 4 • * • • • • • • • *« · «·· '» • • • • • • • • · «« • «· · ** * * · Μ» • * 9 T15992
    In a manner similar to the standing threads 21 to 26 of the core, standing threads may also be provided in the longitudinal direction in the region of the outer jacket, which are braided by the threads of the outer jacket. This is shown in FIG. 1 only by way of example with reference numerals 71 and 72.
