Abstract:
A fabric (144) for use as a stab-resistant insert in protective textiles comprises a plurality of steel cords (100). Each of the steel cords (100) comprises a longitudinal axis (102) and two or more steel filaments (104). Each of the steel filaments (104) forme a twisting angle &agr; with the longitudinal axis (102) of the steel cord (100). The steel cords (100) have two or more of such twisting angles which are substantially different from each other so that any penetrating stab or knife is stopped.
Abstract:
A steel cord for the reinforcement of rubber articles has a two-layer construction in which a core consists of two steel filaments and a sheath arranged around the core consists of nine steel filaments. Preferably the two steel filaments constituting the core are either non-twisted filaments or are twisted at a pitch of not less than 30 mm on average, a ratio (ds/dc) of the diameter ds of each steel filament constituting the sheath to the diameter dc of each steel filament constituting the core is within a range of 35-80%, and a ratio (a/b) of the minor diameter a to the major diameter b of the cord cross-section in an arbitrary position in the longitudinal direction of the cord is within a range of 63-100%
Abstract:
A steel cord adapted for the reinforcement of an elastomer comprises steel filaments of a pearlitic structure. The steel cord has a plastic and elastic elongation at break of x % and a plastic and elastic elongation capability in the vulcanized elastomer of y %, the values x and y fulfilling following equation: y-0.50.ltoreq.x.ltoreq.y+0.50, which means that the total elongation at break does not fall down considerably after embedding the steel cord into an elastomer.

Abstract:
A two-layered twisted steel cord for reinforcing rubber articles, comprising a core including two filaments and a sheath including six or seven filaments wound around the core, in which an average twist pitch of the core is set to be at least 30 mm, and when six filaments are used for the sheath, a ratio of diameter ds of each filament of the sheath to diameter dc of each filament of the core, �(ds/dc).times.100!, is set in a range of 58.0 %
Abstract:
Metallic cord for reinforcing elastomeric articles and apparatus for making same including a round section and equal diameter filaments and a core (11) of two strands of two filaments (5,6,15,16) one strand being untwisted and the other strand having a twist and a first lay length so as to be twisted around the one strand.An outer layer (12) of filaments (21-28) twisted around the core (11) and having the same twist direction and a second lay length half of the core (11) lay length.
Abstract:
A metal cord has cylindrical layers formed of an internal layer, an intermediate layer, and an external layer. The in internal layer includes M threads. The intermediate layer includes N threads wound in a helix around the internal layer. The external layer includes P threads wound in a helix around the intermediate layer. An inter-thread distance, D2, between the threads of the intermediate layer is greater than or equal to 25 μm. An inter-thread distance, D3, between the threads of the external layer is greater than or equal to 25 μm.
Abstract:
An object of the present invention is to make it possible to provide a cord, in particular, a cord for reinforcing a rubber article in which rubber permeation properties are improved by coating filaments as constituents of the cord with rubber in a reliable and stable manner. The cord of the present invention is produced by, when the metal filament is guided to an extruder and extruded together with rubber from a mouthpiece of the extruder so that the metal filament is coated with the rubber, juxtaposing plural metal filaments in the mouthpiece and extruding the metal filaments together with rubber.
Abstract:
Disclosed is a tire-reinforcing steel cord for a radial tire. The tire-reinforcing steel cord has a double layer structure including a first-layer core and a second-layer core provided on the surface of the first-layer core. The first-layer core has an elliptical or rectangular cross section. The tire-reinforcing steel cord can improve processability, fatigue characteristics, and rolling resistance performance of a tire, resulting in improved fuel efficiency. A radial tire using the tire-reinforcing steel cord is also disclosed.
Abstract:
The present invention is to provide a hybrid core rope which does not require maintenance or a hybrid core rope capable of reducing a maintenance task. The hybrid core rope includes a resin solid core in which a plurality of spiral grooves is formed in the longitudinal direction on an outer peripheral surface thereof, a plurality of fiber bundles respectively spirally wound around the outer peripheral surface of the resin solid core along the plurality of spiral grooves, the fiber bundles having thickness to fill the spiral grooves, and a plurality of steel strands spirally wound around the outer peripheral surface of the resin solid core around which the fiber bundles are wound. The fiber bundles and the strands are respectively wound so as to have angles which are not parallel to each other.
