    Core-coat rope
    The present invention relates to a core sheath rope comprising an outer sheath in the form of a hollow braid and an inner sheath in the form of a hollow braid.
    Core 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 sheathing cables is the defective connection between core and sheath. In particular, a relative displacement of core and sheath may occur when using the rope. This shift leads to annoying thick spots, a poor power transmission from the jacket into the core and the overload in the shell, which can lead to the crack of the shell. There are several approaches to avoid 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 FR 334.887, US Pat. No. 2,600,395 A, DE 25 41 763 A and US Pat. No. 4,192,127 A.
    There is still a need for Kem sheath ropes with satisfactory performance properties, particularly as regards the stability of the core and sheath connection throughout the life of the rope.
    The present invention therefore provides a Kem sheath rope comprising an outer sheath in the form of a hollow braid, and an inner sheath in the form of a hollow braid, wherein at certain points thread change between threads of the inner sheath and threads of the outer sheath and / or wraps between Threads of the inner shell and threads of the outer shell are provided, which is characterized in that at these locations 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 Mantels or inner sheath are performed.
    Brief description of the figures:
    Figure 1 shows schematically the structure of a preferred embodiment of a Kem sheath rope according to the invention and its production.
    Figures 2 to 7 show schematically alternative embodiments of the thread change 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. • * »« · · · · · «« · «« · • * «♦ * *« ♦ • Φ t »Λψ • * · T 15991 3
    The term "core" for the purposes of the present invention also includes the mere presence of an internal hollow braid. This means that in one embodiment of a rope consisting only of an outer hollow braid (outer sheath) and an inner hollow braid (inner sheath) without additional Stehfäden in Kem, the inner sheath forms the core of the rope.
    Starting from the yarn changes between threads of the outer jacket and the inner jacket described in the documents cited above, as well as wraps between threads of the outer jacket and the inner jacket, the present invention provides additional longitudinal yarns extending at these points of the change of thread and the looping, respectively ) in front.
    The following options are conceivable. - A change of the thread from the outer shell into the inner shell and vice versa, wherein the guided from the inside to the outside and the outside to inside thread are 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 mantle is carried on again in the inner mantle and, analogously, the thread of the outer mantle again in the outer mantle. The bridge thread lies here between the thread of the inner jacket and the outer jacket and is looped around 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 bias 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 carried 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. • * • • ft · k · · · · · · · · * * * * ft *· * ft * «ft 4 T15991
    In all cases, however, the bridge threads provided according to the invention are covered both by 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.
    Of course, the threads of the inner jacket and the threads of the outer jacket may also be felt around the bridge thread several times and then either continue to be felt in their original position or change position from the outside to the inside and vice versa.
    Preferably, the rope according to the invention in a conventional manner in Kem on one or more extending in the longitudinal direction of the rope filament.
    Kem sheath ropes known from the prior art have a textile core with one or more standing threads extending in the longitudinal direction of the rope, which is surrounded by an inner sheath in the form of a hollow braid, and an outer sheath in the form of a hollow braid.
    In a further preferred embodiment of the present invention, at least a part of the standing threads of the core running in the longitudinal direction of the cable are individually woven into the hollow mesh of the inner jacket. As explained above, the term "thread" also encompasses a plurality of adjacent cable elements, such as e.g. a bundle of several, consisting of a single breakthrough, adjacent standing 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 interwoven into the hollow mesh of the inner shell. Furthermore, the standing threads of the core are connected by the thread change or wraps of the threads of the outer and inner sheath as well as the inventively provided bridge threads with the outer sheath. This results in an even better connection and integration of the core with the inner shell and the outer 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.
    The bridge threads preferably consist of the same material as the threads 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, fiber type (e.g., monofilament, staple fiber, multifilament), fibrous material (e.g., polyamide, aramid, HMW-PE) or construction (e.g., ply of various art and or twist) are contemplated.
    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 the fineness of 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 woven into the hollow braid 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. «* ·» »* ··« * · »» * ··

    The bridge threads and / or the filaments of the outer shell may be made of the same material as the standing threads of the core.
    Moreover, for the rope according to the invention all materials familiar to the person skilled in the art can be selected.
    Figure 1 shows schematically the structure of a preferred embodiment of the rope 1 according to the invention 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.
    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. The core could also be formed exclusively from the inner shell 4, without standing threads 21-28.
    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 Flechtkiöppel on Treibrädem (not shown) are arranged. For example, 12 braided bobbins 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.
    With the Bezugsziffem 5 and 6 positions for thread change or wraps are shown, in which, as explained above, change threads of the outer shell in the inner shell and vice versa and / or threads of the outer shell and threads of the inner shell 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 invention, bridge threads 51 and 61 are now arranged at the thread changing positions 5 and 6, in such a way that they lie between the threads changing from outside to inside (and vice versa) or between the threads that wrap around each other. * »······················································ A * «·· ·· * 7 T15991 come. Apparently, this is achieved by the provision of a breakthrough in the thread change or the wrap around responsible drive wheel.
    After completion of the rope thus these bridge threads are intimately connected to the threads of the inner and outer sheath and thus provide 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 braiding 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 running, which 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.
    According to the preferred embodiment of the present invention, the core has standing posts and part of the standing threads of the core are individually woven into the hollow shell 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. While these are of course in completion of the rope in intimate contact with the threads of the inner shell and the other stationary threads of the core, but are not connected to each other and not woven into the inner jacket.
    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.
