  • Patent number: 7775028
    Abstract: An annular metal cord includes an annular core portion and an outer layer portion. The annular core portion is formed by connecting together both ends of a first strand material which is made up of six twisted first metal filaments. The outer layer portion is formed by winding spirally a second strand material which is made up of six twisted second metal filaments around the annular core portion. The second strand material is wound at a predetermined winding angle relative to a center axis of the annular core portion, and a winding initiating end portion and a winding terminating end portion are connected together. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.

  • Patent number: 7240475
    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.

  • Patent number: 6260343
    Abstract: Strands and wire ropes composed of materials such as high carbon steels and stainless steels can be provided in a compacted, mechanically stress relieved and thermally stress relieved condition. The wires are compacted during stranding to form the individual strands of the wire ropes. The wires can be thermally stress relieved prior to stranding to remove tensile residual stresses. Compaction produces a compressive residual stress state in the strands which increases fatigue resistance. The strands can be thermally stress relieved subsequent to closing. The wires and strands can be heated using a process such as induction heating. The wire ropes can be torque balanced or rotation resistant. The wire ropes have high strength, a high strength-to-weight ratio and enhanced fatigue life. Stainless steel wire ropes also provide corrosion resistance.

  • Patent number: 5649414
    Abstract: A utility loop includes a loop of fiber which forms the loop core. The loop of fiber is made from a thread wrapped into a plurality of loops. The two loose ends of the thread can then optionally be tied together to form the loop of fiber. The outer loop cover of the utility loop is a tube of braided material, which surrounds loop of fiber. The tube of braided material has a tube axis running along a length of the tube of braided material. The tube of braided material includes a relatively small number of relatively large-diameter monofilament fibers, which are braided together in a tubular form. All of the relatively large-diameter mono-filament fibers are oriented to form acute angles with the tube axis. The two loose ends of the tube of braided material are connected together to form the utility loop. Specifically, a first opposing end of the tube of braided material is slipped over a second opposing end of the tube of braided material to thereby form an overlap.

  • Patent number: 5258040
    Abstract: The inventive article is a ligament or tendon prosthesis having multiple longitudinally parallel strands of microporous expanded polytetrafluoroethylene, the individual strands having an average porosity greater than 30% in the areas requiring tissue ingrowth. Additionally, strand dimensions and microstructure are selected so that tissue can penetrate throughout. The prosthesis is formed from multiple loops of a single continuous filament. Densified eyelets are formed in the loop for mounting to bone. The strands are twisted 180.degree. or arranged in a loose braid about the prosthesis axis for improved load distribution during bending of the prosthesis.

  • Patent number: 4843807
    Abstract: A skein of yarn is drawn through a protective tube prefabricated of a woven, tubular textile fabric and is connected in order to form an endless sling. The protective tube is formed of two length sections. These length sections, which are of approximately the same length, are pushed together only slightly during the manufacturing process. In this pushed-together form, they surround the upper reach and the lower reach of the drive formed during drawing in of the skein of yarn by the strands of yarn which are placed around the wheel discs of the manufacturing apparatus.

  • Patent number: 4569190
    Abstract: A twisted cable assembly and a method of making the same. The cable assembly comprises first and second spaced apart end spools and a continuous length of wire. The wire is looped around and extends between the end spools, and sections of the wire between the end spools are twisted into a composite strand. With one embodiment, an elongated malleable wire also is connected to and extends between the end spools to hold the cable assembly selectively in a range of curved positions. With an alternate embodiment, a stiffening wire is connected to and extends between the end spools to inhibit bending of the cable assembly.

  • Patent number: 4257309
    Abstract: Continuous filament rope and method of making same whereby high strength continuous synthetic filaments may be used to provide a rope which in use will have a strength approaching the theoretical strength of the fibers therein. The rope is made by combining a plurality of filaments and twisting the filament group into a light twine in comparison to the rope ultimately desired. The twine is then impregnated with a suitable flexible resin system and wound in a loop having at least a substantial number of turns of the twine. Thereafter the loop is allowed to twist back on itself in response to the twist initially set in the twine so as to form a rope-like center section with loops at each end thereof. Curing of the flexible resin system results in a suitable flexibility of the rope while providing for abrasion and fraying resistance. The loops at the end of the rope may be looped over hooks or pins when in use, with the resulting strength of the rope approaching that of the combined fiber strength.
