The invention further relates to use of such a rope, as well as to a method of manufacturing such a rope.
The rope according to the invention may be used offshore as well as onshore, for example as a lifting rope, a towing rope, a mooring rope, or the like.
A rope of the type as initially identified above is known from WO 2012/150469 A2. See for example the rope 100 or the rope 200 of FIG. 9 of the Abstract of WO 2012/150469 A2. It is seen that said rope 100 has the end connector segment 116 having the first rope-branch-eye 50 and the second rope-branch-eye 52. Similarly, said rope 200 has the end connector segment 216 having the first rope-branch-eye 250 and the second rope-branch-eye 252. It is further seen that a connecting component in the form of the shown connecting spool 58 can be used to connect the ropes 100 and 200 together end-to-end.
It is an object of the present invention to provide an alternative rope, which allows for alternative favourable manners of connecting the rope to other ropes and/or to other types of external objects.
For that purpose the invention provides a rope according to the appended independent claim 1, use of such a rope according to the appended independent claim 10, and a method of manufacturing such a rope according to the appended independent claim 12. Specific embodiments of the invention are set forth in the appended dependent claims 2-9 and 11.
Hence, the invention provides a rope, wherein the rope along a longitudinal rope direction of the rope towards a longitudinal rope end of the rope successively comprises at least a main rope segment, a branching position and an end connector segment, wherein the end connector segment comprises a first rope-branch and a second rope-branch, wherein each of the first rope-branch and the second rope-branch at said branching position is branched off from the main rope segment,
- characterized in that the first rope-branch comprises:
- a noosed first rope-branch portion for making a noosed connection with a thickened rope portion, or
- a thickened first rope-branch portion for making a noosed connection with a noosed rope portion;
- and in that the second rope-branch comprises:

Reference is now made to FIGS. 7A, 7B, 7C, 7D which illustrate an example of a first embodiment of a method of manufacturing a rope according to the invention.
The rope 1″ of FIG. 7A comprises a main rope segment 4″ of, for example, braided or laid rope strands. The rope 1″ further comprises the branching position 5 and a rope end segment 6″. In the shown example, the rope end segment 6″ comprises twelve rope strands 14. It is noted that the construction of the rope end segment 6″ previously was identical to and integral with the rope construction of the main rope segment 4″. In fact, the twelve rope strands 14 of the rope end segment 6″ as shown in FIG. 7A were obtained by mutually disentangling (for example un-braiding or un-laying) the rope strands of said previously identical and integral rope construction.
The rope 1′ of FIG. 7B has the same main rope segment 4″ and the same branching position 5 as the rope 1″ of FIG. 7A. However, the rope 1′ of FIG. 7B has a rope end segment 6′, which is different from the rope end segment 6″ of the rope 1″ of FIG. 7A. That is, the rope 1′ of FIG. 7B has two rope end portions 11′ and 12′. Each of said rope end portions 11′ and 12′ has been obtained by mutually entangling (for example braiding or laying) six of the twelve rope strands 14 of the rope 1″ of FIG. 7A. Purely to illustratively elucidate this, the twelve mutually disentangled rope strands 14 in FIG. 7A are shown in two separately arranged groups, each having six mutually disentangled rope strands 14.
The rope 1 of FIG. 7C, which is the same as the rope 1 of FIGS. 1-5, may be obtained by transforming the rope end portion 11′ of the rope 1′ of FIG. 7B into the first rope-branch 11 having the noosed first rope-branch portion 21N, and by transforming the rope end portion 12′ of the rope 1′ of FIG. 7B into the second rope-branch 12 having the thickened second rope-branch portion 22T. Said transformations can be performed by many various methods, including many various methods known in the art, for making such a noosed first rope-branch portion 21N and such a thickened second rope-branch portion 22T.
It is noted that the mutually unequal lengths L1 and L2 of the two rope-branches 11 and 12 of the rope 1 (see FIGS. 2A, 2B) may for example be obtained by considerably shortening the rope strands 14 used for the rope end portion 12′ in FIG. 7B prior to transforming the rope end portion 12′ into the second rope-branch 12 of FIG. 7C.
FIG. 7D shows another example of a rope that may be obtained from the rope 1′ of FIG. 7B. The rope 401 of FIG. 7D comprises the main rope segment 404, the branching position 405 and the end connector segment 406. The end connector segment 406 comprises the first rope-branch 411, which has the noosed first rope-branch portion 421N, and the second rope-branch 412, which has the thickened second rope-branch portion 422T. The rope 401 of FIG. 7D may be obtained by transforming the rope end portion 11′ of the rope 1′ of FIG. 7B into the first rope-branch 411 having the noosed first rope-branch portion 421N, and by transforming the rope end portion 12′ of the rope 1′ of FIG. 7B into the second rope-branch 412 having the thickened second rope-branch portion 422T. It is seen that in the example of FIG. 7D the attainable maximum second effective length of the second rope-branch 412 is higher than the attainable maximum first effective length of the first rope-branch 411.
Reference is now made to FIGS. 8A, 8B, which illustrate an example of a second embodiment of a method of manufacturing a rope according to the invention, more specifically a method of manufacturing the rope 501 of FIG. 8B.
FIG. 8A shows two separate first and second ropes 501A and 501B, respectively. The first rope 501A comprises the noosed first rope-branch portion 521N.

The rope 601 of FIG. 9B is obtained by splicing an end portion of a main rope segment of the rope 601A into an intermediate portion of a main rope segment of the rope 601B in such manner that the rope 601 has the shown main rope segment 604, the shown branching position 605 and the shown end connector segment 606 having the shown two rope-branches 611 and 612, wherein the first rope-branch 611 comprises the noosed first rope-branch portion 621N of the first rope 601A as the noosed first rope-branch portion 621N of the rope 601, and wherein the second rope-branch 612 comprises the thickened second rope-branch portion 622T of the second rope 601B as the thickened second rope-branch portion 622T of the rope 601.
It is noted that many various splicing techniques may be applied for said splicing of the end portion of the main rope segment of the rope 601A into the intermediate portion of the main rope segment of the rope 601B.
Reference is now made to FIGS. 10A, 10B, which illustrate an example of a fourth embodiment of a method of manufacturing a rope according to the invention, more specifically a method of manufacturing the rope 701 of FIG. 10B.
FIG. 10A shows a rope 701′ of multiple load-bearing sub-ropes 741A, 741B, 742A, 742B within an outer jacket 731.
The rope 701 of FIG. 10B is obtained by coupling the sub-ropes 741A, 741B together and by coupling the sub-ropes 742A, 742B together, in such manner that the rope 701 has the shown main rope segment 704, the shown branching position 705 and the shown end connector segment 706 having the shown two rope-branches 711 and 712, wherein the first rope-branch 711 comprises the shown noosed first rope-branch portion 721N of the rope 701, and wherein the second rope-branch 712 comprises the shown thickened second rope-branch portion 722T of the rope 701.
It is noted that many various coupling techniques may be applied for said coupling the sub-ropes 741A, 741B together and for said coupling the sub-ropes 742A, 742B together. Said many various coupling techniques may comprise many various splicing techniques for splicing the sub-ropes 741A, 741B into one another and for splicing the sub-ropes 742A, 742B into one another. Said many various coupling techniques may further comprise many various techniques for forming the noosed first rope-branch portion 721N and for forming the thickened second rope-branch portion 722T.
Reference is now made to FIGS. 11A, 11B, which illustrate a rope according to the invention, wherein the rope is similar to the rope of FIG. 1, however wherein the embodiment of the noosed first rope-branch portion of the rope of FIGS. 11A, 11B is different from that of the rope of FIG. 1.
In the examples of FIGS. 1, 5A, 6A, 7C, 7D, 8A, 8B, 9A, 9B, 10B it is seen that each time a noosed portion of the rope concerned is of a type in which the line of the adjustable loop that forms the noosed portion is transversely running through itself in a transversely slidable manner. This is a known embodiment of a noosed portion of a rope for making a noosed connection with a thickened portion of a rope.
The rope 801 of FIGS. 11A, 11B comprises the main rope segment 804, the branching position 805 and the end connector segment 806. The end connector segment 806 comprises the first rope-branch 811, which has the noosed first rope-branch portion 821N, and the second rope-branch 812, which has the thickened second rope-branch portion 822T. The difference between the noosed first rope-branch portion 821N of the rope 801 of FIGS. 11A, 11B and the noosed portion 21N of the rope 1 of FIG. 1 is that the noosed first rope-branch portion 821N is not of the known type in which the line of the adjustable loop that forms the noosed portion is transversely running through itself in a transversely slidable manner. Instead, the line of the adjustable loop that forms the noosed portion 821N of the rope 801 of FIGS. 11A, 11B is coaxially running through itself in a coaxially slidable manner. Also this coaxially slidable embodiment is a known embodiment of a noosed portion of a rope for making a noosed connection with a thickened portion of a rope.
The difference between the shown situations of FIGS. 11A and 11B is that in FIG. 11B the adjustable loop that forms the noosed portion 821N of the rope 801 is in a more tightened condition than in FIG. 11A.
It is further noted that each of the above-mentioned examples of a method of manufacturing a rope according to the invention (said examples being illustrated by FIGS. 7, 8, 9, 10) can be used to manufacture a rope according to the above-mentioned “first preferable embodiment” of a rope according to the invention.
