A straightening device for straightening cables includes two rows of rollers, an adjusting device for manually adjusting a distance between the rows of rollers, a measuring device for recording the distance between the rows of rollers, and an indicator device with which deviations of the actual value of the distance between the rows of rollers, determined by the measuring device, from a nominal value is visually indicated. The indicator device has two optical error indicating elements for indicating too high and/or too low an actual value compared with the nominal value of the distance, as well as an optical correct indicating element for indicating that the actual value of the distance corresponds with the nominal value.

Elongated bodies made from high tenacity polyolefin fibers are provided that are useful as fishing lines, and processes for making the lines. Fibers having tenacities of at least 39 g/denier are braided and fused together to form braided bodies having very small diameters.

A method is provided for manufacturing a multistrand cable having a 1N structure and including a single layer of N strands wound in a helix. Each strand includes an internal layer of M internal threads and an external layer of P external threads. The method includes a step of individually assembling each of the N strands, during which, in chronological order, the M internal threads are wound, the P external threads are wound, and the M internal threads and the P external threads are elongated such that a structural elongation associated with the P external threads of each strand is greater than or equal to 0.05%. The method further includes a step of collectively assembling the N strands, during which the N strands are wound to form the cable.

A steel cord for reinforcing a breaker or belt ply in a rubber tire having a core group and a sheath group. The core group consists of two to four core steel filaments with a first diameter dc and the sheath group consists of one to six sheath steel filaments with a second diameter ds. The ratio dc/ds of the first diameter dc to the second diameter ds ranges from 1.10 to 1.70. The two core steel filaments are untwisted or have a twisting step greater than 300 mm. The sheath group is twisted around the core group with a cord twisting step in a cord twisting direction. The ratio of the difference in residual torsions of the core group and the sheath group to the difference in saturation level between the core group and the sheath group ranges from 0.10 to 0.65, preferably from 0.10 to 0.60.

Articles such as a net, a round sling or a splice include a resin-impregnated lengthy body having multifilamentary yarns comprised of high performance polyethylene (HPPE) fibres and a polymeric resin dispersed throughout a cross-section of the multifilamentary yarns. The the polymeric resin is a homopolymer or copolymer of ethylene and/or propylene, wherein the polymeric resin has a density as measured according to ISO1183 in the range from 860 to 930 kg/m.sup.3, a melting temperature in the range from 40 to 140? C. and a heat of fusion of at least 5 J/g.

Disclosed is a method for producing a high strength synthetic strength member containing rope and a resultant rope, comprising multiple layers of twisted and braided yarns, wherein individual sheaths enclosing individual strands are of a material such as HMPE, PTFE or UHMWPE with a lower decomposition temperature than the material of said strands being aramid, the method comprising subjecting parts of the rope to heat and tension thereby pre-stretching and creating a non-uniform or non-round shape of said strands, further choosing a combination of braid and twist angles as well as braid compressive forces to accommodate specific strength and elongation relation between the individual rope layers.
