  • Patent number: 11162214
    Abstract: A longitudinal element produced with a core made of high-strength fibers and at least one metal casing, preferably steel, surrounding this core. In this way, there is the significant advantage that these high-strength fibers, which are very lightweight in relation to their strength, are protected in a number of ways, namely against humidity, moisture, UV light and other environmental influences. In addition, the metal casing provides the fibers with protection against transverse loads. In this way, all the high-strength properties of the traction or suspension means are maintained over a sustained period.

  • Patent number: 10760212
    Abstract: A method for producing a rope, wherein fiber bundles are applied with a liquefied matrix material upstream of and/or at a twisting point to form fiber strands, and are embedded into the liquefied matrix material during stranding, by which fiber strands a fiber core of the rope is formed and wires or wire strands are wound about the fiber core. The matrix material of the fiber strands is hardened after the stranding, and the fiber strands are subsequently stranded directly with one another without further application to form the fiber core. Preferably the fiber strands are heated, during or after the stranding thereof to form the fiber core, so that the matrix material softens at least individual of the fiber strands, preferably all the fiber strands, softens and connects with the matrix material of another of the fiber strands, and is subsequently hardened, forming an integral bond with one another.

  • Patent number: 8747468
    Abstract: Biocompatible coatings and spin finishes that can be applied to polyhydroxyalkanoate (PHA) polymers, and medical devices made from PHA polymers, have been developed. The coatings impart good lubricity to PHA polymers, particularly to fibers and braids made from these materials, making the coatings ideal for use on medical devices such as PHA braided sutures. The spin finishes can be applied to PHA fibers to facilitate their manufacture, and also for their conversion to other products, including medical textiles. The spin finishes serve to protect multifilament fiber bundles, and keep them intact following extrusion, and also to impart lubricity to the fiber bundles and monofilament fibers so that they are not damaged in subsequent processing steps particularly in textile processing. The coating reduces tissue drag of, for example, braided sutures.

This produces a substantial increase in the life of the rope. The method for manufacturing such rope involves wrapping plastic bands on the core just prior to laying outer strands on the core and on top of the plastic bands. Thereafter, the so formed rope is impregnated with molten plastic, which is then allowed to solidify.

  • Publication number: 20020189227
    Abstract: A cable includes a plurality of strands around a core, where the space between the strands and/or between core and strands is filled with a polyurethane-based polymer material. The cable is produced by depositing the polymer material over the core and/or strands with a coating device a certain distance upstream of the cabling point. The polymer's composition and coating point are determined so that the strands are placed around the core when the polymerization of the compound is sufficiently advanced so that the polymer formed is in a viscoplastic state suitable to form an approximately continuous adherent coating layer, but still sufficiently fluid to insinuate into the interstices between core and strands and between the strands.

  • Patent number: 5732541
    Abstract: A filament rope may be produced continuously by the method and apparatus of this invention. In an upper portion of a frame of the apparatus is a unit having strand carrying spools that move about to braid the strands into a core of the rope. During braiding the strands overlap to form sets of pairs of transversely aligned openings which decrease in size as the rope core is drawn away from the braiding unit by a tension wheel assembly. While the openings are still large, a filament length carried by a first cylinder passes through one pair of strand openings. The cylinder then is withdrawn and the filament length severed leaving a filament segment in that pair of openings. Next, a second filament segment is placed in the other strand opening pair by a second cylinder. After filament segment insertion a tamping tool engages the strands and inserted filament segments to promote opening size reduction and improve formation of a compressive fit by the strands on the filament segments.
