Abstract:
Steel cables are utilized for reinforcing a wide variety of rubber articles. For instance, pneumatic tires are normally reinforced with steel tire cords. It is important for such reinforcing cables to exhibit good fatigue and corrosion resistance. It has been unexpectedly found that the fatigue and corrosion resistance of such cables can be improved by incorporating syndiotactic-1,2-polybutadiene into the interstices between the steel filaments in such cables. This invention more specifically relates to a cable for reinforcing rubber articles having improved fatigue and corrosion resistance which is comprised of a plurality of steel filaments and syndiotactic-1,2-polybutadiene, wherein the syndiotactic-1,2-polybutadiene is dispersed within interstices between said steel filaments.
Abstract:
A tire steel cord formed of more than three strands twisted together, at least one of the strands being marked so as to formed therein with zig-zagging marked parts which form gaps between strands, rubber accordingly immersing the steel cord into its center part through the thus formed gaps so as to fill in a cavity in the center part of the steel cord.
Abstract:
A steel cord for the reinforcement of rubber products and the like has an open twisted structure comprised of 3 to 6 steel filaments each having an ellipsoidally helical shape, and has a particular tensile elongation under a load of 5 kg.
Abstract:
A method of making metallic cable (10) suitable for reinforcing elastomeric articles which comprises two or more substantially identical helical formed filaments (11, 12, 13) nested together and secured to one another by axially spaced apart applications of an adhesive substance.
Abstract:
The invention relates to a metallic reinforcing cord (10) for tyres for vehicle wheels, comprising from two to ten metallic wires (11) twisted together with a twisting pitch (P) and each having a predetermined diameter. In at least some cross sections of the metallic reinforcing cord (10), at least two of said metallic wires (11) are arranged to a minimum mutual distance greater than, or equal to, 2.5 times the predetermined diameter.
Abstract:
[Object] A hollow stranded wire line, for manipulation, having an excellent torque transmittability is provided.[Solution] A hollow stranded wire line 2 for manipulation is a hollow stranded wire line 2 that is advantageously used as a stranded wire line for manipulation in a medical instrument, and a side wire 4 or a side strand which is an outermost layer has a forming rate that is greater than 100% and not greater than 110%. The side wire 4 or the side strand having been formed has a spiral shape in which a flatness that is an aspect ratio obtained by a major axis being divided by a minor axis is preferably not less than 1.01 and preferably not greater than 1.10.
Abstract:
In order that spaces, including a space in the central portion, inside a steel cord used as a reinforcement by being embedded in a tire or the like are filled with an uncured rubber, the uncured rubber is coated on plural steel core filaments which are then stranded to form a single layer steel cord, the core then being stranded with uncoated outer layer filaments. Consequently, it is possible to exhibit satisfactory corrosion resistance and satisfactory fatigue resistance as a steel cord, shorten a curing time in tire component assembling or the like to attain energy saving and prolong the life of a steel cord itself and the life of a tire or the like using the same as a reinforcement. Further, production can be performed at low cost.
Abstract:
J strands form a core. K outer strands are wound around it in a helix with pitch PK, each having a cord with an L wire inner layer of diameter d1, and an M wire outer layer of diameter d2, wound around the inner layer in a helix with pitch p2; with (in mm): 0.10
Abstract:
A compact metal cable having two layers (C1, C2) of construction 1+N, rubberized in situ, usable in particular as a reinforcing element for a tire belt for a heavy industrial vehicle, comprising a core or inner layer (C1) comprising a single core wire of diameter d1, and a saturated outer layer (C2) of N wires of diameter d2 wound together in a helix at a pitch p2 around the layer C1. The layered cable has the following characteristics (d1, d2, p2 in mm): 0.15
Abstract:
A two-layer cord having a number of wires in the outer layer, enclosing, but not completely, a cord core formed by a plurality of core wires, and in which the core wires are not preformed, while at least some of the outer wires are preformed.
