In particular, the rope has N longitudinal elements, in particular in addition to the soul. Preferably, N = 6. In particular, the rope is a six-strand wire rope. However, seven-stranded or eight-stranded ropes are also conceivable. In particular, N is at least 4, advantageously at least 5 and particularly advantageous at least 6 and / or at most 12 , advantageously at most 10 and most advantageously at most 8th , Advantageously, the longitudinal elements each have an at least substantially constant cross-section. Preferably, the longitudinal elements are strands, which in turn may be constructed from a plurality of individual wires, which may in particular be formed at least substantially identical to each other. Likewise, it is conceivable that a longitudinal element formed, for example, as a strand, has different individual wires and / or other components such as inserts, fibers, sheathing elements or the like. In particular, in the case where a longitudinal element is formed as a strand, the longitudinal element advantageously has a lay length which corresponds to at least five times and preferably at least seven times and / or at most one fifteen times and preferably no more than one eleven times the diameter of the longitudinal element. In principle, longitudinal elements can be used with different impacts. In addition, a direction of impact of the wire rope may be identical or opposite to a direction of impact of the longitudinal elements or at least individual longitudinal elements. By "at least substantially identical" objects are meant in particular objects that are constructed so that they can each perform a common function and preferably differ in their construction apart from manufacturing tolerances at most by individual elements that are immaterial to the common function, and advantageous objects that are identical except for manufacturing tolerances and / or in the context of manufacturing capabilities, with identical objects in particular also mutually symmetrical objects to be understood. The fact that an object has an "at least substantially constant cross-section" should be understood in particular to mean that for any desired first cross-section of the object along at least one direction and any second cross section of the object along the direction of a minimum surface area of a differential area, which is formed when superimposing the cross sections, a maximum of 20%, advantageously not more than 10% and most preferably at most 5% of the area of the larger of the two cross sections ,

In this context, a "wire" is to be understood as meaning, in particular, an elongate and / or thinner and / or at least mechanically bendable and / or flexible body. Advantageously, the wire has an at least substantially constant, in particular circular or elliptical cross section along its longitudinal direction. Particularly advantageously, the wire is designed as a round wire. But it is also conceivable that the wire is at least partially or completely formed as a flat wire, a square wire, a polygonal wire and / or a profile wire. For example, the wire may be formed at least partially or completely from metal, in particular a metal alloy, and / or organic and / or inorganic plastic and / or a composite material and / or an inorganic non-metallic material and / or a ceramic material. For example, it is conceivable that the wire is designed as a polymer wire or a plastic wire. In particular, the wire may be formed as a composite wire, such as a metal-organic composite wire and / or a metal-inorganic composite wire and / or a metal-polymer composite wire and / or a metal-metal composite wire or the like. In particular, it is conceivable that the wire comprises at least two different materials, which are in particular arranged according to a composite geometry relative to each other and / or at least partially mixed together. The wire is advantageously designed as a metal wire, preferably as a steel wire, in particular as a stainless steel wire. If the helix has several wires, they are preferably identical. But it is also conceivable that the helix has a plurality of wires, which differ in particular with regard to their material and / or their diameter and / or their cross-section. Preferably, the wire and / or the longitudinal element has a particular corrosion-resistant coating and / or sheath such as a zinc coating and / or an aluminum-zinc coating and / or a plastic coating and / or a PET coating and / or a metal oxide coating and / or a ceramic coating or the like.

The splice is advantageously a long splice and / or produced in the manner of a long splice. Preferably, the splice is a cable splice. Preferably, the number of longitudinal elements of the splice corresponds to the number of longitudinal elements of the rope. Particularly preferably, the longitudinal elements of the splice are the longitudinal elements of the rope. Preferably, the splice is made from an exit rope of the rope prior to its connection to an endless rope. In particular, the splice is a joint between ends of the output rope of the rope. Advantageously, the cable has at least one further cable section, which is free of a splice. The cable section and the further cable section preferably form the cable. However, it is also conceivable that the cable has several cable sections, each comprising at least one splice, for example, if a part of the rope is exchanged and a corresponding replacement piece is spliced by means of at least two splices. The splice advantageously has a maximum diameter which deviates from the diameter d of the rope by at most 10%, advantageously at most 8%, particularly advantageously at most 6% and preferably at most 5%, and in particular is greater than this.

Preferably, at least some and advantageously all of the longitudinal elements each form at least one insertion end. Particularly preferably, at least some, and advantageously all, of the longitudinal elements respectively form exactly two insertion ends, wherein advantageously one insertion end is formed in each case by one end of a longitudinal element. Advantageously, the insertion ends are inserted instead of the soul in an interior of the cable section. Particularly advantageously, the splice has a plurality of splices, in particular N splices, at which longitudinal elements and preferably insertion ends preferably intersect, in particular such that they dip in opposite directions into an interior of the splice. In particular, the splice site comprises at least one, in particular exactly one, splice node, preferably a crotch node. Advantageously, the splice in the region of the splice N + 1 on a surface lying longitudinal elements, of which preferably two intersect at the splice. Alternatively, it is conceivable that two of the longitudinal elements are placed next to each other at the splice, so that they form, for example, a parallel node. Particularly advantageously, these two longitudinal elements, in particular the longitudinal elements intersecting at the splice point, each form a spigot end, wherein the corresponding spigot ends, in particular starting from the splice point, are inserted in opposite directions instead of the core into the interior of the splice. Preferably, a male end extends from a center of a splice site to an end of the male end, particularly in the interior of the splice. Particularly preferably, two insertion ends forming a splice point each extend from the splice point in opposite directions of the splice, in particular at least predominantly in its interior, preferably in place of a soul.

In particular, a length of a section lying on a surface of the splice, which comprises in particular not inserted sections of the intersecting or alternatively juxtaposed longitudinal elements and is preferably defined and / or formed by these, is at most 15 * d, advantageously at most 10 * d advantageously at most 5 * d and preferably at most 2 * d. In particular, a length of the splice node of the splice is correspondingly at most 15 * d, advantageously at most 10 * d, particularly advantageously at most 5 * d and preferably at most 2 * d.

A diameter of the splice may be greater than the diameter d of the rope in a region of a splice, in particular because at the splice a cross-section of the splice comprises N + 1 longitudinal elements. In particular, at least one splice of the splice defines a maximum diameter of the splice.

Preferably, the splice has 2 * N male ends, more preferably each end of each longitudinal element is a male end. However, it is also conceivable that at least two ends of longitudinal elements or of a single longitudinal element abut and in particular on a surface of the splice and are glued and / or welded and / or otherwise connected to each other, for example. A number of insertion ends may be less than 2 * N in this case. For example, for a rope having six longitudinal members, only four longitudinal members may form insertion ends while two longitudinal members are merely abutted against a surface of a corresponding splice. A breaking force of the splice is determined in this case, for example, mainly by the spigot, while the lying on joint and possibly about welded ends of the longitudinal elements can absorb only small forces. A corresponding splice is advantageously easy to produce, in particular since only a reduced number of longitudinal elements is spliced.

Preferably, the insertion end is at least partially sheathed with at least one sheath material, in particular wrapped. The sheathing material can be, for example, a splice strip that can advantageously be wound around an insertion end. It is also conceivable that the cladding material is applied in a different way on a spigot, for example applied, melted, extruded or the like. In particular, the sheath material is provided to increase a diameter of the shank end due to its sheath. Advantageously, the male ends are encased with cladding material such that their diameters correspond at least substantially to a diameter of the core. Preferably, a diameter of the insertion end, in particular in an uncoated state, is smaller than a diameter of the core. By "at least substantially" is to be understood in this context in particular that a deviation from a predetermined value in particular less than 15%, preferably less than 10% and particularly preferably less than 5% of the predetermined value.

Advantageously, the insertion end has a length of at most 40 * d, particularly advantageously of at most 30 * d, preferably of at most 25 * d and particularly preferably of at most 20 * d. Advantageously, the splice has at least 2 * N-8, particularly advantageously at least 2 * N-6, preferably at least 2 * N-4, particularly preferably at least 2 * N-2 and preferably 2 * N insertion ends. In particular, the splice has at least two, advantageously at least four, particularly advantageously at least six, preferably at least eight, particularly preferably at least ten, and preferably at least twelve and / or 2 * N insertion ends having a length of at most 50 * d, advantageously of at most 40 * d, particularly advantageously of at most 30 * d, preferably of at most 25 * d and more preferably of at most 20 * d.

In particular, the total length of the splice corresponds to a distance between outermost insertion ends of the splice, preferably along its longitudinal direction. Preferably, the splice is bounded on opposite end faces by the core of the rope. In particular marginal insertion ends of the splice adjoin the core of the rope, wherein the total length of the splice advantageously corresponds to a distance between these marginal insertion ends, in particular their ends facing the core. Advantageously, the splice has a total length of at most 80 * N * d, particularly advantageously of at most 60 * N * d, preferably of at most 50 * N * d and particularly preferably of at most 40 * N * d. In particular, the splice, for example in the case of a six-stranded wire rope, has a length of at most 600 * d, advantageously of at most 500 * d, particularly advantageously of at most 400 * d, preferably of at most 300 * d and particularly preferably of at most 250 * d ,

In an advantageous embodiment of the invention, it is proposed that a plurality of longitudinal elements each have at least one insertion end with a length of at most 50 * d. Advantageously, several longitudinal elements each have two insertion ends with a length of at most 50 * d. In particular, all insertion ends of the splice have a length of at most 50 * d on. In addition, it is conceivable that all longitudinal elements of the splice each have two insertion ends each having a length of at most 50 * d. But it is also conceivable that at least one insertion end of the splice has a length which is greater than 50 * d. In particular, the splice may have insertion ends of different lengths. Advantageously, all the insertion ends of the splice are the same length. As a result, a high degree of time and / or cost efficiency in splicing can advantageously be achieved.

A low material requirement on sheath material, and in particular a low degree of production effort, can be achieved in particular if a total length of regions with insertion ends is at most 100 * N * d, where N is a number of longitudinal elements of the rope. Advantageously, the total length of regions with insertion ends is at most 80 * N * d, more preferably at most 60 * N * d, preferably at most 50 * N * d, and most preferably at most 40 * N * d. In particular, at least some of the regions with insertion ends are arranged adjacent to one another, preferably directly, preferably along the longitudinal direction of the cable section. Advantageously, all regions with insertion ends can be arranged adjacent to each other, in particular directly. In particular, the total length of regions with insertion ends may at least substantially correspond to the length of the splice.

It is further proposed that the splice comprises at least one, preferably exactly one, intermediate portion arranged between insertion ends, which contains at least a portion of a core and / or a, in particular non-metallic, replacement element. The replacement element acts here in particular as a substitute for the soul. For example, the replacement element may be at least partially made of plastic and / or rubber. Preferably, a cross section of the replacement element at least substantially corresponds to a cross section of the soul. Advantageously, the intermediate region is arranged in a middle of the splice. When viewed along the longitudinal direction of the cable section, a first half of all the insertion ends of the splice in front of the intermediate area and a second half of all the insertion ends of the splice behind the intermediate area are considered to be particularly advantageous. In particular, the intermediate region has a length of at least 100 * d and advantageously of at least 200 * d. In the case that the splice is longer than 600 * d, a length of the splice may advantageously be composed of the total length of the male ends and a length of the intermediate region. In particular, these lengths can add up to a length of the splice of 1200 * d, in particular for reasons of compliance with standard specifications, although of course other and advantageously longer lengths are conceivable. In the case of a destination length for the splice of 1200 * d, for example, the intermediate region may have a length of 600 * d and the region with insertion ends likewise a length of 600 * d. Likewise, the intermediate area can be extended accordingly and / or the area with insertion ends can be shortened accordingly. In this way, a splice can be produced with a predetermined length, with a production cost can be advantageously reduced due to short insertion ends.

Preferably, however, the splice is free of such an intermediate piece, so that advantageously a splice having a short overall length can be provided.

Furthermore, it is proposed that the splice has a number of longitudinal element end regions, in particular located in the interior of the splice and / or inserted, which are each arranged in a vicinity of at least one other longitudinal element end region. In this way, a splice can be provided with an advantageously reduced overall length. Preferably, the splice additionally comprises two longitudinal member end portions disposed in a vicinity of the core, particularly at opposite ends of the splice. A "near zone" in this context should be understood in particular to mean a region whose length, preferably along the longitudinal direction of the cable section, is at most 20 * d, advantageously at most 10 * d, particularly advantageously at most 8 * d, preferably at most 5 * d and especially preferably at most 3 * d. Specifically, two longitudinal member end portions in the vicinity are adjacent to each other. Advantageously, the splice has at least one spacer element arranged between adjacent longitudinal element end regions, which is preferably arranged instead of the core in the interior of the splice. In particular, the spacer element has a length of at least 1 * d, advantageously of at least 2 * d, particularly advantageously of at least 3 * d and preferably of at least 4 * d and / or of at most 15 * d, advantageously of at most 10 * d advantageously of at most 8 * d and preferably of at most 6 * d, for example a length of 5 * d. In particular, the region with insertion ends can comprise the spacer elements, but advantageously not any intermediate element. Preferably, the spacer is in the longitudinal direction of the cable section in abutment with the adjacent Längselementendbereichen. Advantageously, a formation of large gaps in a tensile and / or bending load of the splice can be prevented thereby. In particular, relative movement of adjacent longitudinal member end portions advantageously results in the formation of two narrow spaces between each of the longitudinal member end portions and the second Spacer, preferably instead of forming a single wide gap. It is also conceivable that at least two, in particular two, Längselementendbereiche are immediately adjacent, preferably without a spacer disposed therebetween. In addition, it is conceivable that the splice has at least two and advantageously 2 * N-2 paired Längselementendbereiche. For example, these can be welded together and / or adhesively bonded and / or connected to one another by means of at least one clamping connection, in particular in addition to a clamping generated by the longitudinal elements surrounding the longitudinal element end regions. Preferably, in this case, the two, in particular two, Längselementendbereiche in shock.

An advantageously reliable and / or resilient splice may be provided, in particular, when the longitudinal member end regions are end regions of male ends. In particular, in the case where the splice comprises 2 * N male ends, the 2 * N-2 male internal ends preferably form the 2 * N-2 longitudinal element end regions. In addition, the two marginal insertion ends advantageously form the two longitudinal element end regions adjacent to the core.

In a further embodiment of the invention it is proposed that the splice comprises at least one splice, which has at least two counter-inserted insertion ends and at least one insert element with at least one receiving area, which is provided for at least partially receiving the opposite inserted insertion ends. In particular, the insert element is provided for at least partially receiving a splicing node, in particular a cross knot, which advantageously forms the counter-inserted insertion ends or corresponding longitudinal elements forming same. Preferably, the insert element is a splicing doll. Advantageously, the insertion elements on a plurality of spiral-like further receiving areas, which are each provided to receive a longitudinal element. In particular, the insert element N-1 has such further receiving areas. The insert element is provided in particular for replacing the core of the cable in an area of the splice site, in particular in an area of its splicing node. Preferably, the receiving area is deeper and / or wider than the other receiving areas, so that this is advantageous for partially receiving two longitudinal elements instead of only one longitudinal element is particularly advantageous to achieve a not or at least only slightly larger cross-section of the splice in the region of the splice and in particular their splice node. Advantageously, the insert element is at least partially made of plastic, although other suitable materials such as rubber or soft metals are conceivable. The insert element can be designed in particular as a 3D printed component. Preferably, the insert element is adapted to a shape and / or shape and / or expression of the splice node of the splice site. Particularly preferably, the receiving area and the further receiving areas of the insert element are designed and / or arranged such that the longitudinal elements of the splice extend around the insert element in such a way that they are contactless, at least in a region of the insert element. In particular, it is conceivable that the receiving region has a variable cross section, which merges in particular of at least one region for receiving a single insertion end in at least one region for receiving the splice node. In principle, it is conceivable that the insert element has a maximum length which corresponds to a sum of a length of the two counter-inserted insertion ends. Advantageously, the insert element has a length of at least 1 * d, particularly advantageously of at least 2 * d, preferably of at least 3 * d and particularly preferably of at least 5 * d and / or of at most 100 * d, advantageously of at most 50 * d, particularly advantageous of at most 20 * d, preferably of at most 10 * d and more preferably of at most 8 * d on. This can advantageously be reduced undesirable thickening in node areas. In addition, advantageously occurring in nodal areas mechanical loads of a splice can be reduced.

In addition, it is proposed that the insertion end has a waviness whose amplitude is at least 0.5% and / or at most 20% of an amplitude of waviness of the longitudinal element, in particular in a different from the insertion end portion of the longitudinal element, preferably outside the interior of the splice and / or is arranged outside a splice node area corresponds. Advantageously, the longitudinal element is at least partially straightened in a region of the insertion end.

In particular, the ripple corresponds to a deviation from a straight course. In this case, the amplitude may be an amplitude of a course of the insertion end or of the longitudinal element in a view perpendicular to a longitudinal direction of the insertion end or the longitudinal element and / or a corresponding amplitude in a projection perpendicular to a longitudinal direction of the insertion end or the longitudinal element. The insertion end and the longitudinal element are preferably wavy in at least two vertical spatial directions. Particularly preferred follow the insertion end and the Longitudinal element in each case a spiral and / or spiral-like course, wherein advantageously the course of the insertion end can be generated at least by means of stretching in the longitudinal direction of the longitudinal element from the course thereof. Advantageously, the amplitude of the waviness of the insertion end corresponds to at least 1%, more preferably at least 2% and preferably at least 3% and / or at most 15%, more preferably at most 10% and preferably at most 8% of an amplitude of the waviness of the longitudinal element. As a result, advantageously, an internal geometry of a splice can be precisely adjusted.

In a further embodiment of the invention, it is proposed that the splice has at least one further insertion end which has a different length than the insertion end. As a result, advantageously a high variability with regard to a design of a splice can be achieved. In addition, the load-bearing properties of a splice can be precisely adjusted. In particular, the splice may have different lengths of insertion. The insertion end and the further insertion end may be formed by different longitudinal elements, which may also differ, for example, with regard to at least one property, such as with regard to a cross section, a diameter, a material, a lay length or the like. A length of the insertion ends can be selected in particular depending on a nature of the longitudinal elements. It is conceivable that insertion ends of a single splice point have different lengths. As a result, it is advantageously possible to produce regions of different lengths, each with two adjacent insertion ends, wherein adjacent insertion ends can be of the same length. It is also conceivable that each one splice node forming insertion ends are the same length. In particular, in this case, two adjacent male ends arranged between two splices may be of different lengths. In particular, in the case where the splice has butt-joined and / or bonded, eg welded, end portions of longitudinal members on its surface and only some of the longitudinal members form spigot ends, for example, longer spigot ends may be located in areas where there is a surface on the splice End portions of longitudinal elements are in abutment and / or connected, such as welded, are, so that advantageously a resilient, yet compact splice can be provided.

Furthermore, it is proposed that the splice has a plurality of splices, in particular not separated by an intermediate region and / or a replacement element, which are arranged at irregular distances from one another, in particular in addition to any irregular intervals between splices separated by the intermediate region due to an intermediate region , As a result, a high degree of variability with regard to adaptation of a local load capacity of a splice can advantageously be achieved. For example, gaps between splice sites may increase from one edge of the splice to the middle thereof. Furthermore, it is conceivable that distances between splice sites decrease from the edge of the splice to the middle thereof. Advantageously, the splice has different distances between different adjacent splice sites. In particular, a first distance between two adjacent splices may deviate from a second distance between two other adjacent splices. It is conceivable that the splice has the same insertion length and in particular all the insertion ends of the splice are the same length, wherein the irregular distances are generated by means of at least one spacer. For example, the splice may have spacers of different lengths and / or regions of adjacent Längementsementendbereiche with and without spacer. Advantageously, the splice on different lengths of insertion, by means of which the irregular distances are at least partially generated.

Alternatively, it is proposed that the splice has a plurality of splice locations arranged at at least substantially regular intervals. In this way, advantageously, a splice which can be produced easily and reliably can be provided. In addition, a splice with a uniformly distributed local load capacity can be provided, in particular for a wire rope with identical longitudinal elements. Preferably, all splices of the splice are arranged at regular intervals. In particular, in the case that the splice has at least one intermediate region, it is conceivable that the splices of the splice are arranged in groups at regular intervals between splice sites.

In an advantageous embodiment of the invention, it is proposed that at least one test cable section of the cable, in particular with a diameter d, with at least one Testeinsteckende in a prestressed state and under tensile load of the Testeinsteckendes at least 1000 times, advantageously at least 2000 times, particularly preferably at least 5000 times, preferably at least 10000 times and more preferably at least 15000 times, in particular in each case by at least 90 °, advantageously in each case by at least 120 ° and preferably in each case by at least 150 ° about at least one test disk having a diameter of at most 80 * d, advantageously of at most 60 * d, and particularly advantageously of at most 40 * d, is damage-free bendable. In particular, one has in the test rope piece inserted portion of the Testeinsteckendes a length of at most 50 * d, advantageously of at most 40 * d, particularly advantageously of at most 30 * d on. In particular, the test rope piece in the test attempt alternately by two opposite and advantageously curved in the opposite direction test discs by the specified angle as a total angle without damage be bendable, so for example by 45 ° to a first of the test discs and 45 ° to a second of the test discs. Advantageously, the test insertion end is designed analogously to the insertion ends of the cable section and in particular encased with the covering material. In addition, the test rope piece is advantageously designed analogously to the rope. It is conceivable that the test cable piece comprises a plurality of insertion ends. It is also conceivable that the test cable piece comprises an entire test splice. Advantageously, the test rope piece comprises only one test insertion end, which is preferably inserted at one end of the test rope piece instead of its core in its interior.

In particular, the rope corresponds 90a the rope 12a the passenger transport railway 92a in its non-spliced condition. By splicing the rope 90a can the designed as an endless rope rope 12a the passenger transport railway 92a getting produced.

In particular, the longitudinal elements run 16a - 26a spiral around the soul 94a , The longitudinal elements 16a - 26a are about the soul 94a stranded around.

The soul 94a in the present case has a cross-section which is larger than a cross-section of the longitudinal elements 16a - 26a , In addition, the soul points 94a advantageously a cross section with circular segment-shaped recesses and / or indentations for the longitudinal elements 16a - 26a on, the advantageous according to a stranding of the longitudinal elements 16a - 26a for the soul 94a follow a spiraling course around.

The ripple of the insertion end 28a is by means of stretching and / or straightening the longitudinal element 16a from the ripple, in particular due to its stranding generated. In the 5 is the ripple of the insertion end 28a because of this, schematically straighter Presentation not shown. The ripple of the insertion end 28a leads in particular in a view perpendicular to the longitudinal direction 118a of the rope section 10a to a wave-like and in particular sinusoidal course of the insertion 28a , A wavelength of the ripple of the insertion end 28a is advantageously greater than a wavelength of waviness of the longitudinal element in this consideration 16a outside the splice site 84a , in particular a lay length of the longitudinal element 16a equivalent.
