Abstract:
A stainless steel cable particularly for surgical procedures comprises a plurality of individual wire filaments (20). Groups of wire filaments (20) are twisted together in a first helical direction around a central wire filament to make a strand (10). A plurality of strands (10) are twisted together in a second helical direction around a core strand to make a strong, flexible cable. The first helical direction has the opposite sense to that of the second helical direction. In one embodiment, the cable has one hundred and thirty three wire filaments (20), each of diameter 0.0025 inch (64 νm), arranged in nineteen equivalent strands.
Abstract:
A hybrid rope constructed of a plurality of strands, wherein each strand is constructed of a fiber center, a jacket surrounding the fiber center, and a plurality of wires surrounding the jacket. The fiber center can be constructed of one or more high-strength synthetic fibers or yarns. The jacket can be constructed of polypropylene, thermoplastic polyurethane, high-density polyethylene, linear low-density polyethylene, nylon or other similar materials. The jacket can have a braided or woven design and adds a protective layer between the fiber center and the wires. The wires can be constructed of high-strength steel wires, galvanized steel or stainless steel. The fibers or yarns that make of the fiber center are twisted to lay right and then covered with the jacket. The wires then surround the jacket and are twisted to lay to the left. This creates a torque-balanced condition of the hybrid rope.
Abstract:
The invention relates to a cellulose textile cord (50) having an at least triple twist (T1, T2, T3), comprising at least N strands (20a, 20b, 20c, 20d), where N is greater than 1, which strands are twisted together to a final twist T3 in a final direction D2, each strand being made up of M pre-strands (10a, 10b, 10c), where M is greater than 1, which pre-strands are in turn twisted to an intermediate twist T2 (T2a, T2b, T2c, T2d) in an intermediate direction D1 which is opposite to D2, with every pre-strand consisting of a spun fibre (5) that has been twisted on itself to an initial twist T1 (T1a, T1b, T1c) in the direction D1, wherein at least half the N times M spun fibres are spun cellulose fibres. The textile cord can advantageously be used as reinforcement in vehicle pneumatic tires, especially in the belt or the carcass ply of said pneumatic tires.
Abstract:
A steel cord (10) adapted for the reinforcement of rubber products, comprises a core strand (12) and six peripheral strands (14) concentrically surrounding the core strand (12). Each of the core and peripheral strands (12, 14) comprises a centre of two or more centre filaments (16) and two layers of filaments surrounding the centre. The core strand (12) has a diameter D1 which is greater than the diameter D2 of the peripheral strands (14). All the filaments (18, 20) of each layer have substantially the same diameter and a radially outer layer has a twist angle which is greater than a twist angle of a radially inner layer of the same strand. Each of the strands (12, 14) in the cord is composed of no more than twenty-six filaments (16, 18, 20) being twisted together.
Abstract:
The present invention relates to a hybrid cord comprising an inner layer (1) in steel cord, an intermediate layer (2) in a high module and high toughness fibre and an outer layer (3) in a Polyolefin fibre. The present invention also refers to its application in an 8 (4x2) cords braided hybrid cable or any other type of hybrid cable presenting another construction, in braided or twisted cables.
Abstract:
An annular metal cord and an endless metal belt are provided which have superior breaking strength and which are easy to be produced. The annular metal cord includes an annular core portion 3 and an outer layer portion 4. The annular core portion 3 is formed by connecting together both ends of a first strand material 1 which is made up of six twisted first metal filaments 5. The outer layer portion 4 is formed by winding spirally a second strand material 2 which is made up of six twisted second metal filaments 6 around the annular core portion 3. The second strand material 2 is wound at a predetermined winding angle relative to a center axis of the annular core portion 3, and a winding initiating end portion and a winding terminating end portion thereof are connected together. Since it is not that six second strand materials 2 are not wound but that the second strand material 2 is wound six rounds, there only has to be the single second strand material 2, and there is only one connecting portion. As a result, the breaking strength of the annular metal cord can be made large, and the production thereof can be facilitated.
Abstract:
Un cable metallique comprend une pluralite de torons (4-12) torsades, chique toron metallique (4-12) etant recouvert d'une gaine (16) de caoutchouc ou d'un substitut du caoutchouc. Chaque toron (4-12) comprend une pluralite de fils metalliques (14) torsades ensemble d'au moins les fils exterieurs (14), le sens de tors de chaque toron (4-12) etant contraire au sens de tors d'au moins les fils exterieurs (14) de chaque toron (4-12) adjacent; le cable est recouvert d'une gaine externe (18) de caoutchouc ou d'un substitut du caoutchouc. De cette maniere, les fils metalliques (14) des torons adjacents (4-12) ne s'entrecroisent pas et la contrainte qu'ils subissent est ainsi diminuee.
