    Abstract: A method of making a splice termination for a synthetic fiber rope, said synthetic fiber rope comprising a fiber core and at least a layer of synthetic fiber strands twisted around said fiber core, said method comprising steps: (a) Providing a synthetic fiber rope having a laid construction and an unrestrainedend, (b) Measuring tails having a length of L1 from the end of the rope, applying cloth or tape on the synthetic fiber rope for a length L2 from the end of tails to form a taped section, (c) Bending the synthetic fiber rope at the point having a length of about L1+L2/2 from the end of the rope to form an eye, (d) Untwisting the core and the strands of the tails, dividing and bundling up the yarns equally amongst the number strands of the outer layer of the synthetic fiber rope so that forming a plurality of bundled tails, (e) Tucking and pulling the plurality of bundled tail(s) respectively through between respective strand(s) of the outer layer of the synthetic fiber rope next to the taped section to form a tucked section, (f) Repeating step of tucking and pulling the plurality of bundled tail(s) respectively through between respective strand(s) of the outer layer of the synthetic fiber rope next to the previously tucked section to form a spliced termination.

    Abstract: Disclosed herein are methods for producing core-sheath structures by shaping at least one filament bundle containing a plurality of filaments to form at least one shaped strand of filaments, and braiding a plurality of strands, including the at least one shaped strand of filaments, over a core to form the core-sheath structure containing a braided sheath of the strands surrounding the core, wherein the shaped strand of filaments is an untwisted strand having a twist level of less than 1 turn per meter, a cross-sectional aspect ratio of the shaped strand of filaments is at least 3:1, as measured in the braided sheath, a thickness of at least a portion of the braided sheath ranges from about 10 to about 200 μm, and the braided sheath comprises a synthetic fiber having a tensile strength of greater than 12 cN/dtex. Also disclosed herein are core-sheath structures formed by such methods.

    Abstract: The invention relates to a rope made of textile fiber material, comprising a rope core and a sheath surrounding the rope core, wherein the sheath, an intermediate sheath located between the sheath and the rope core and/or a reinforcement located between the sheath and the rope core comprise(s) a twine of excess length, the twine of excess length being formed in that it comprises at least a first yarn and a second yarn which are twisted together, the first yarn having a greater length than the second yarn, measured in an untwisted state of a unit length of the twine. In a further aspect, the invention relates to a method of manufacturing a twine of excess length for the above-mentioned rope.

    Abstract: With a wire rope comprising at least one plastic core (11) and a number of wire strands (15) twisted around the latter a helical groove (20) is respectively produced by machining around the periphery of the plastic core (11) for each wire strand (15). The cross section of these helical grooves (20) is respectively matched to the outside diameter of the wire strands (15). The plastic core (11) is provided with the helical grooves (20) for receiving the wire strands (15) by this machining directly before the wire strands (15) are wound onto said core. By thus forming the wire rope by means of this machining in order to produce helical grooves of the plastic core, optimal guiding of the wire strands in the twisted state is achieved, and so overall there are improvements to the properties of the wire rope.

    Abstract translation: 使用包括至少一个塑料芯（11）和围绕其缠绕的多个线股（15）的钢丝绳，分别通过围绕每个线的塑料芯（11）的周边机械加工来产生螺旋槽（20） （15）。 这些螺旋槽（20）的横截面分别与线股（15）的外径匹配。 塑料芯（11）设有螺旋槽（20），用于在线股（15）缠绕到所述芯之前直接通过该加工来接收线股（15）。 通过这种机械加工形成钢丝绳以产生塑料芯的螺旋槽，实现了扭绞状态下的线股的最佳引导，因此总体上改进了钢丝绳的性能。
