    Spliced rope end
    The present invention relates to a rope end which is spliced to form a loop.
    In various fields of technology, e.g. in the field of yachting or in the field of personal security or climbing rope ends are needed, which are designed in the form of a sling or an eye. The end of the rope must be fixed so that the tensile forces occurring in the respective application area can be absorbed without loosening the loop
    There are two basic methods of forming a loop around the end of the rope:
    In the first method, the rope end piece is knocked back to form a loop, applied over a certain distance to the rope section leading to the loop, and connected thereto, e.g. about a cut, fixed. A corresponding system is known, for example, from EP 0 768 100 B1, EP 1 659 209 A2 and US 2007/0137163 A1.
    These systems can be manufactured by means of machines, which results in a low susceptibility to errors. Due to the abrupt transition from the rope to the sling, on the one hand there is an unappealing visual impression and on the other hand there is also the danger that the rope end or the sling will, as a result of this transition, hit obstacles, e.g. can impose on a branch. Although this transition can be mitigated by a beveling of the rope end, but not completely avoided.
    Alternatively, it has long been known to splice the rope end, i. to introduce the folded-back cable end piece into the cable section leading to the loop and to guide it over a certain distance in the cable section.
    When subjected to tensile stress, the spliced rope end piece is stuck inside the rope section, so that the loop does not come loose. For this, however, it is necessary to guide the rope end piece over a relatively long distance (hereinafter called "splice length") within the rope section leading to the loop. A splice made in this way has no abrupt transition, but runs in a uniform taper of the loop or the eye to the rope.
    Spliced rope ends are e.g. in US 3,102,715 A, GB 1 480 826 A and WO 2011/071387 Al.
    Such a spliced rope end can only be made by hand, but this is associated with a certain risk of error. Especially in applications where the safety aspect plays a major role, each splice must have an equally high breaking load. Due to the strong influence of the skill of the splice-producing person on the quality of the splice, this is only insufficiently guaranteed.
    From EP 2 186 551 A1, a spliced rope end is known, which is characterized in that the splice region is spaced from the loop by a stitching region in which the rope end piece and the rope section leading to the loop abut each other and are sewn together by a load-bearing belt.
    US 5,205,803 A and WO 2008/069380 A1 describe the sewing of woven or knitted ribbon-shaped elements.
    Although the rope end described in EP 2 186 551 does not have an abrupt transition and is secured by a mechanically produced (reproducible) seam, nevertheless the rope end or the loop and the splicing area are still substantially thicker or more voluminous in relation to the rope diameter and thus stiffer - as with the rope stitching and splicing described above.
    Stiffness and thickness are a problem in particular in the application of a man protection in tree work, as it can still lead to a hanging of the rope at obstacles (branches).
    The present invention has for its object to provide a spliced and secured with a Vemähung rope end available, which is designed in terms of its stiffness and thickness over the known from the prior art rope ends
    This object is achieved with a loop-spliced end of a rope comprising a rope end piece folded back to form the loop and a rope section leading to the loop, wherein a splice region is provided in which the rope end piece is guided inside the rope section leading to the loop, and wherein the rope is a core / sheath rope, which is characterized in that
    Seilendstück in splice a portion of the core, preferably the entire core is removed, that in the splice a load-carrying Vemähung the Seilendstückes is provided with the cable leading to the rope section, and that a load-carrying Vemähung in a region of the loop leading to the rope portion, which forms part of Kernes, preferably has the entire core is provided.
    Brief description of the figure:
    Figure 1 shows schematically the structure of a preferred Ausfühnmgsform a cable end according to the invention.
    Detailed description of the invention:
    According to the present invention, a spliced rope end of a core / sheath rope is provided in which the core or part of the core is removed in the rope end at least in the splicing area.
    Kem / sheath ropes can, as is well known, a single Kem (eg braided to a game), or even a core, which consist of several, detachable parts (eg several twisted game, the twists without Connection with each other next to each other) consists. For the purposes of the present invention, the term "part of the core" means part of the core forming materials, e.g. a part of the threads forming the core.
    By "removing a portion of the core" is accordingly the removal of at least a portion of the materials forming the core, e.g. by removing one of several threads forming the core, but also by detaching one or more games from a rope contained in the core.
    By contrast, the term "the entire core" means the core in its shape present in the remainder of the rope, i. with all the core-forming materials, e.g. all twisted or braided yarns.
    In a preferred embodiment of the present invention, the entire core (ie all parts of the core) is removed in all regions of the cable end, in which according to the invention a part of the core is removed.
    · * 4 »
    The term "part of the nucleus" is to be understood as "at least part of the nucleus".
    Conversely, conversely, when referring to the removal of "the nucleus", this is to be understood as the removal of only a portion of the nucleus, unless explicitly indicated to remove the entire nucleus.
    Due to the removal of the core in the rope end piece, the remaining jacket is compressible and therefore has a smaller diameter in the splice area than the original core / sheath rope. However, this also means that the splice area as such has a smaller increase in thickness compared to the normal thickness of the cable than in the case of cables known from the prior art or even virtually no increase in the thickness.
    To secure the spliced rope end a load-bearing Vemähung is provided. The cutting may optionally be in the form of several separate cuts. At least load-bearing removal of the cable end piece with the cable section leading to the loop in the splice area and load-bearing removal in a region of the cable section leading to the loop, in which a part of the core, preferably the entire core, is present, must prevail. For the purposes of the present invention, the term " load-bearing cut " means that the cut is stable to the tensile loads occurring during use of the respective rope, i. does not dissolve or tear. In particular, a load-bearing Vemähung for the purposes of the present invention is capable of a safety rope according to EN 1891 a minimum breaking load of the rope end of at least 10 kN, preferably at least 15 kN, measured according to EN1891: 1998, Chapter 5.10.1, ensure. Such ropes have a diameter of 8.5 to 16 mm. For ropes with deviating diameters, correspondingly lower or higher minimum fracture loads must be ensured. The production of such load-bearing seams is known per se to a person skilled in the art, see e.g. EP 0 768 100 Bl.
    Preferably, the Vemähung or the Vemähungen is machined. The material for the cutting can be chosen arbitrarily; Preference is given to seams of polyethylene terephthalate (PET), polyamide (PA) or high molecular weight polyethylene (HMW-PE, known by the name Dyneema®). > -! · Ι ^ i irivM tal k 'V »> · ≫ ^ > taf > ' > -! · Ι ^ i irivM tal k 'V »> · ≫ ^ > taf > ' • · s.
    The core is preferably also located in the rope end piece in the region of the loop. It follows that even the loop itself has no or only a small increase in thickness in relation to the normal thickness of the rope.
    Also in the loop leading to the rope section may be provided an area in which the core is removed. This also leads to a further reduction in the thickness of the rope end. In this embodiment, the core can also be removed in the cable section over at least part of the splicing area.
    It is only important that the inventively provided Vemähung at least includes a portion of the loop leading to the rope section, in which a part of the core, preferably the entire core, is present. However, although part of the core will be removed in the area of the rope in the rope section leading to the sling, it will be understood by those skilled in the art that at least enough of the core material must remain to ensure tensile strength of the rope in connection with the cutting. i _
    Preferably, the splice region and the region of the loop leading to the rope portion, which has a part of the core overlap. This means that the rope end piece guided inside the cable section without a core or with only a part of the core at least partially rests on the core present in the cable section.
    Preferably, in particular in this embodiment, a single continuous load-bearing Vemähung is provided.
    In a further preferred embodiment, at least part of the region of the cable end piece in which the core is removed is additionally filled. This can be done in particular by removing part of the material forming the jacket, e.g. by gradual removal of single or multiple game done. This results in a further reduction in the thickness of the rope end.
    In a further preferred embodiment, at least in a part of the region of the cable end piece, in which the core is removed, there is a reinforcing element of the cable end which is different from the core.
    It can also be present at least in a part of the region of the loop leading to the rope section, in which the core is removed, a reinforcing element of the rope end. Likewise, a reinforcing element may also be present at least in a part of the region of the cable section leading to the loop which has a part of the core.
    Preferably, there is a continuous reinforcing element.
    The reinforcing element is preferably arranged in the interior of the jacket. This reinforcing element can perform various tasks, such as e.g. the stabilization of the shape of the sling. Preferably, the reinforcing element serves to increase the tensile load resistance of the rope end.
    The remaining after removal of the core sheath of the rope is load-bearing. If it is abraded, the system loses tensile strength.
    Therefore, a glazing-resistant reinforcing element is preferably provided, which is preferably arranged in the interior of the shell.
    The shape and design of the reinforcing element depends on its objective. The reinforcing element may in particular be in the form of a flat band.
    Preferably, at least part of the reinforcing element is encompassed by the veining provided according to the invention or the veining provided according to the invention.
    A particularly preferred embodiment of the cable end according to the invention is characterized in that - the entire core is removed in the entire cable end - the rope section leading to the sling has a region in which the entire core is present - the cable section leading to the sling has a region in front of the sling, in which the entire core is removed and - the splice region and that region of the loop leading section, in which the entire core is present, overlap.
    Also in this embodiment, a single continuous penetration is preferably provided.
    Another aspect of the present invention relates to a cable having a cable end according to the invention.
    The rope end or rope according to the invention is constructed as a core / sheath rope in a manner known per se, it being possible to use all materials and constructions known in the art for the core or the sheath, such as, for example, high strength polyamide or polyester materials.
    As the material of the preferably provided reinforcing element, in particular in the form of a band, high-strength materials such as e.g. Dyneema® (HMWPE), aramid and Vectran® (LC polyester) in question. The reinforcing element may e.g. woven or braided, in particular in the form of a collapsible hollow braid present.
    Examples
    The following discussion of Figure 1 relates to a single core embodiment (i.e., a core made, for example, of rope braided yarns). The statements are analogously also for embodiments with a core consisting of several parts.
    Figure 1 shows schematically a rope end 1 of a core / sheath rope. The core of the rope is shown schematically by reference numeral 8. In the rope end 1 shown in the figure, a loop 2 is formed by the repelling of the rope end 3. The rope end 3 is spliced in a known manner with the cable section 4 leading to the loop 2 by being inserted into the cable section 4 and extending over a certain area within the cable section. The region between the first point seen from the loop at which the tail contacts the rope section 4 and enters it (for example in the form of a puncture) to the end of the tail 3 is referred to as a splice region 5.
    In the embodiment shown in FIG. 1, the (entire) core is removed in the cable end piece in the entire splice region 5, but also in the entire region of the loop 2. Also in a part of the loop leading to the cable section 4 of the (entire) core is removed. This results in a part 4a of the rope section with core 8 and a part 4b of the rope section without a core.
    According to the invention a load-bearing Vemähung 6 is provided. ························································································································································································································ 999 9199 99 999 ··
    This sewn in a part of the splice region 5, the (coreless) Seilendstück 3 with the loop leading to the cable section 4. The [branch-carrying Vemähung also includes sections of a core 8 having part 4a of the loop leading cable section. 4
    In FIG. 1, the cut 6 is shown as a single continuous cut. But there are also several separate Vemähungen possible.
    According to FIG. 1, the splice region 5 and the core part 4 of the cable section 4 preferably overlap partially. The seam 6 in this case comprises a part of the splice region 5 in which the core is removed both in the cable section 4 and in the cable end piece 3, and a part of the splice region 5 in which the cable section 4 has a core 8.
    The regions of the cable end 1 in which no core is present can be further tapered, which is shown only schematically in FIG. 1 for the cable end 3 in the splicing region 5.
    Preferably, a reinforcing element 7 (shown as a dotted line) is provided in the cable end 1. This can, as shown in Figure 1, continuous from the cable section 4 to the end of the splice region 5 or even beyond. As shown in FIG. 1, the reinforcing element 7 is preferably also encompassed by the seam 6.
    Examples 1 to 4:
    Rope ends according to the invention have been manufactured from ropes of the following types:
    Rope 1: Kem-Mantel-Rope (DM 11,5mm) with PET-jacket (24-braided) and a core made of several twisted PA-dimes.1
    Rope 2: Kem-Mantel-Rope (DM 11,5mm) with PET-coat (24-plaited) and a Kem with a braided PA-rope as well as central twists made of Polyolefm.
    Rope 3: Kem-Mantel-Rope (DM 13mm) with PA-jacket (16-plaited) and a Kem made of several twisted PA-sets.
    Rope 4: Kem-Mantel-Seil (DM 13mm) with PET / Polyolefm-Mantel (16-plaited) and a Kem made of several twisted PA-Zwimen. 1 PET: polyester; PA: polyamide
    First, the maximum tensile strength (HZK) of the original rope in free length was measured.
    To determine the maximum tensile force of the sheath without core (s), the entire core (ie all core components) was removed. The maximum tensile force of the remaining free-length jacket was measured.
    For the production of cable ends according to the invention, the entire core was removed in each case. The coreless rope end piece was in each case repelled to form a loop and spliced with the rope section leading to the loop and sewn under load-bearing conditions, as shown schematically in FIG.
    The maximum tensile force of the resulting loop was measured.
    In the case of ropes 1 and 2, another embodiment was produced with a reinforcing element in the form of a strip of Dyneema® with a width of 10 mm and a thickness of 1.4 mm, which was arranged and mowed as shown schematically in FIG.
    In these cases, the maximum tensile force of the sling and reinforcing element was measured. For comparison purposes, the maximum tensile force of the loop was also measured after the jacket had been cut through (ie if only the reinforcing element is present as a load-bearing element).
    The results are shown in the following table:
    table
    Rope length HZK in free length [kNJ HZK of the shell in free length ikNl HZK of the loop without reinforcing element [kN] HZK of the loop with reinforcing element [kN] HZK of the loop only with reinforcing element (sheath cut) [kN] rope 1 32.9 15.0 20.2 20.2 17.1 rope 2 31.1 14.9 18.3 18.5 16.7 rope 3 37.4 27.6 22.0 rope 4 31.1 25.1 21, 1
    • ······ * · k
    It can be seen from the above table that despite removal of the entire core, the resulting loop still has sufficient tensile load resistance. At the same time, the resulting rope end is much thinner compared to conventional spliced rope ends.
