    Abstract: A flexible traction organ that can be wound and unwound, in particular for passenger and/or goods lifts, said organ comprising at least one stranded cable consisting of a tensile resistant material. The core strand of each stranded cable is surrounded by a flexible thermoplastic plastic layer. A production line for embedding several stranded cables in a flexible thermoplastic layer comprises a respective reel for unwinding the stranded cable, a device for accurately aligning the stranded cable, a heating element for pre-heating the stranded cable, at least one extruder for co-extruding the stranded cable in a flexible plastic sheathing, a cooling vat, a reel storage unit, a cutting unit and a reserve reel. The extruder, a wire guide and at least one die can be adjusted individually, conjointly and in relation to one another on a plane (P) that runs at an angle to the cable plane (E). The unwound stranded cables are degreased and/or pre-treated to improve the adhesion of the plastic sheathing, and pre-heated to a temperature of approximately ±20° C. in relation to the melting temperature of the flexible, thermoplastic plastic that surrounds the core strand and are sheathed with liquefied plastic in the extruder.

    Abstract: The invention improves rubber permeability while making a cord diameter compact. A metal cord is constituted by a layered structure having a core comprising totally 6 to 12 filaments sectioned into 1 to 4 filament bundles, and a sheath comprising 8 to 15 filaments arranged around the core. Each of the filament bundles includes a waved filament modeled in a two-dimensional wave shape and a non-waved filament, in a state before being bundled. The core makes the wave of the waved filament three-dimensional within the core by applying torsion to each of the filament bundles.

    Abstract: A pneumatic tire comprises a carcass toroidally extending between a pair of bead portions and a belt arranged outside the carcass in a radial direction of the tire and composed of at least one belt layer, in which the belt layer is made from a plurality of steel cords, each cord being formed by twisting 2 to 4 filament bundles each consisting of two steel filaments paralleled with each other so as to have a structure that major axes of the filament bundles constituting the cord are set toward substantially the same direction. In the belt layer, the major axes of the filament bundles in the cords constituting the belt layer are arranged substantially in a row in a widthwise direction of the belt.

    Abstract: Provided is an elastomer reinforcement cord in which the problem of stress concentration at an interface between an elastomer and a metal cord is solved and the durability is thereby improved. The elastomer reinforcement cord includes metal filaments (1a) and (1b), and a polymer material (3) having a melting point or softening point of 80° C. to 160° C. The elastomer reinforcement cord has a core (11) and at least one sheath layer (12). In a region surrounded by a line connecting the centers of the metal filaments constituting the outermost sheath layer at a cross-section in a direction orthogonal to an axial direction after vulcanization, when a region occupied by other than the metal filaments is defined as a gap region, the polymer material is contained in this gap region, and a filling rate, which is a ratio of the area of the polymer material, is higher than 120%, taking the area of the gap region as 100%.
