  • Publication number: 20070269654
    Abstract: The invention relates to a process for making a monofilament-like product from a precursor containing at least one strand of a spun yarn made from polyolefin staple fibres, comprising the steps of a) exposing the precursor to a temperature within the melting point range of the polyolefin for a time sufficient to at least partly fuse adjacent fibres and b) simultaneously stretching the precursor at a draw ratio of at least 1.0. The invention further relates to a monofilament-like product obtainable by said process showing improved abrasion resistance, and to the use of said monofilament-like product for making various semi-finished and end-use products.

  • Publication number: 20060119120
    Abstract: The invention is related to a roundsling in the form of an endless loop consisting of a core containing at least two turns of a load-bearing strand material comprising fibres with a tenacity of at least 10 cN/dTex and a protective covering around said core, wherein the strand material is in the form of a braided or laid rope, the terminal ends of which are connected with a splice. The invention further relates to a method for constructing a roundsling comprising a step of winding a braided or laid rope on two reels such that part of the turns is on the reels and another part is between the reels wherein the part between the reels is supported, and a step of making a splice in the two terminal ends of the rope.

  • Publication number: 20060048494
    Abstract: The invention relates to a method to make a splice in a laid rope construction comprising at least two strands, wherein: a) one end of a first rope end is split in a first and a second part comprising respectively a first and a second number of strands, the first number of strands being at most one more than the second number of strands; b) the first part is tucked from one side into an opening in a second rope, such that the opening has a first number of strands of the second rope on one side and a second number of strands on the other side, where the first and second number differ at most by one; c) the second part is tucked from the other side into the opening in the second rope; and d) step b) and c) are repeated at least 3 respectively at least 3+1 times, whereby the respective openings in the second rope are separated such that the first and the second part have crossed over at least all the strands of the second rope once and the first and second part leave the second rope at respective last openings.

  • Publication number: 20050229770
    Abstract: Endless rope containing primary strands, the primary strands containing laid-up secondary strands, the laid-up secondary strands containing rope yarns, wherein the primary strands have been laid up from 3, 4 or 6 secondary strands, wherein the rope contains a splice in at least every primary strand and wherein the rope preferably has been laid up from 3, 4 or (1+6) primary strands or, alternatively, has been braided from 8 or 12 primary strands.
