Abstract:
A wire strand (10) comprises a plurality of wires (12, 16, 20). The wires comprise a central king wire (12), a first layer (14) of wires (16) arranged around the king wire, and a second layer (18) of wires (20) arranged around the first layer. The king wire is formed of steel having a carbon content of at least 0.3 wt%. Each wire of the first layer is formed of steel having a carbon content which is less than the carbon content of the king wire. Each wire of the second layer is formed of steel having a carbon content which is greater than, or the same as, the carbon content of the wires of the first layer.
Abstract:
A steel cord (20) comprises a plurality of steel filaments (22, 24) arranged in parallel to the longitudinal axis of the steel cord (20) without twisting. The steel cord (20) further comprises a wrapping filament (26) twisted around the steel cord (20). Each of said steel filaments (22, 24) is a flat wire having flat surfaces. The steel filament (24) near the center of the steel cord (20) has a bigger width than the steel filaments (22) further away from the center of the steel cord (20) such that the cross-section of said steel cord (20) approximates an oval shape with the bending stiffness around the shorter axis of the oval shape being greater than the bending stiffness around the longer axis. In a tire, the steel cord being used as a reinforcement, the longer axis being arranged perpendicular to the radial direction of the tire.
Abstract:
A method for manufacturing a component includes a step of providing at least one metallic element. A surface of the at least one metallic element is modified to facilitate a bonding of the at least one metallic element to a polymeric layer. The polymeric layer is then bonded to the at least one metallic element to form the component.

Abstract:
A steel cord (10) for reinforcing rubber product comprises at least one core strand (12) and outer strands (14), the outer strands (14) are helically twisted around at least one core strand (12). Each of the strands (12, 14) comprises core steel filaments (16, 20) with the number of m and outer steel filaments with the number of n. The diameter of the core steel filaments in the core strand is Dcc, the diameter of the outer steel filaments in the core strand is Doc, the diameter of the core steel filament in the outer strand is Dco, and the diameter of the outer steel filament in the outer strand is Doo. The ratio of Dcc/Doc is not less than 1.04, the ratio of Dco/Doo is not less than 1.03, and the ratio of Doc/Dco is not less than 1. The core steel filaments and outer steel filaments are polygonally preformed before being twisted into strands. The steel cord is used for reinforcing off-the-road tire.
Abstract:
The invention relates to a steel cord (C-1) with three layers (C1, C2, C3) and a 3+M+N structure, that is rubberized in situ and comprises: a first layer or central layer (C1) formed by two wires (10) of diameter d1 assembled in a helix at a pitch p1; a second layer (C2) formed by M wires (11) of diameter d2, which are wound around the central layer (C1) in a helix at a pitch p2; and a third layer (C3) formed by N wires (12) of diameter d3, which are wound around the second layer in a helix at a pitch p3. The cord is characterised in that it has the following characteristics: (d1, d2, d3, p1, p2 and p3 being expressed in mm): - 0.08 = d1 = 0.5; - 0.08 = d2 = 0.5; - 0.08 = d3 = 0.5; - 3 1 2 3
Abstract:
A metal rope (10) comprises wires (16, 18). The wires (16, 18) have a surface of stainless steel. At least those wires (18) exposed to the surface of the rope (10) are coated with a transparent polymer (22) on the stainless steel. The transparent polymer (22) is selected from the group consisting of thermoplastic polyesters, polyimides, polyamides and polyphtalamides, or a copolymer thereof. The metal rope (10) can be an element of a fabric, such as a woven (144) or knitted structure (150). The metal rope (10) be used in architectural, building and decorative applications.
