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.
Abstract:
A steel filament adapted for the reinforcement of elastomer or for thermoplastic products has a carbon content ranging up to 0.20 per cent by weight. The steel filament is provided with a coating promoting the adhesion with elastomer or thermoplastic products. The steel filament is drawn until a final diameter of less than 0.60 mm and a final tensile strength of more than 1200 MPa. Intermediate heat treatments are avoided so that the carbon footprint of the steel filament is substantially reduced.
Abstract:
There are provided an annular concentric stranded bead cord which can realize a reduction in weight while ensuring its strength, a method for manufacturing the same and a vehicle tire.The manufacturing method is a method for manufacturing an annular concentric stranded bead cord by forming a sheath layer by winding spirally a lateral wire round an annular core. After the sheath layer has been formed, the lateral wire is annealed in a pressure-reduced inactive gaseous atmosphere with an annealing quantity which exceeds a heating quantity (temperature×time) which is necessary for vulcanization of a vehicle tire with the annular concentric stranded bead cord embedded in a rubber of the vehicle tire when building the same and is shaped so that “Diameter shaping ratio (%)=H/D×100” becomes 20% or larger and 105% or smaller.

Abstract:
A steel rope safety system includes at least one steel rope having at least one strand, and the at least one rope or at least one strand is compacted. Further, a method is provided for making a steel rope safety system comprising the step of providing at least two wires, the step of stranding the wires thereby forming a strand for a rope and the step of compacting the strand. There is likewise provided the use of compacted steel ropes as impact reducing material.
Abstract:
Steel wire is coated with a metal layer such that the metal layer has a surface with roughnesses. A surface roughness Ra of above 0.25 μm is reached. Preferably, the roughnesses are randomly dispersed at the surface. The result is an improved visual aspect and an increased resistance against corrosion.
Abstract:
Cables used with wellbore devices to analyze geologic formations adjacent a wellbore including one or more armor wires, the armor wires formed of a high strength core surrounded by a corrosion resistant alloy clad. The alloy clad includes such alloys as beryllium-copper based alloys, nickel-chromium based alloys, superaustenitic stainless steel alloys, nickel-cobalt based alloys, nickel-molybdenum-chromium based alloys, and the like.
Abstract:
A steel cord comprises a core with one or more core steel filaments and further comprises a first layer of intermediate steel filaments twisted around the core, and a second layer of second steel filaments twisted around the first layer. At least one of the intermediate steel filaments is individually coated by means of a polymer with a minimum thickness of 0.010 mm. The polymer reduces the fretting between the coated intermediate steel filaments and the other steel filaments and makes the steel cord suitable for reinforcement of carcass plies of a tire.
Abstract:
A method for making a metallic cord made up of one or more metallic wires comprises: making at least two layers of at least two metallic elements including copper and zinc on the surface of a base wire; heating the layers to cause the metallic elements thermodiffusion to transform into a primary alloy layer; making a layer of copper on the primary alloy layer; drawing the wire provided with the primary alloy layer and outer copper layer into a metallic wire through dies so that the outer copper layer is diminished during passing through the dies, and a secondary alloy layer is formed as a result of transformation of the primary alloy layer and the outer copper layer which is caused by frictional heat during passing through the dies.
Abstract:
A coated metal reinforcement element for polymeric or elastomeric materials comprises a coating of: a polymer or prepolymer compatible with and co-polymerizable, co-vulcanizable or crosslinkable with said polymeric or elastomeric material to be reinforced, and bearing functional groups; either covalently bonding to the metal surface of said reinforcement element; or forming covalent bonds with the outward directed first functional groups of a mono-or multimolecular layer of a bifunctional adhesion promotor intercalated between said metal by its second functional groups. A method for the coating includes a one step and a two step procedure.
