    Abstract: Une carcasse métallique (1) destinée à renforcer les articles en caoutchouc tels que les pneus, comprend un noyau constitué d'entre deux et quatre filaments en acier (2) et d'une couche de filaments en acier (3, 4) disposée autour du noyau. Tous les filaments ont un diamètre compris entre 0,15 et 0,40 mm et sont retordus dans le même sens et au même pas. Sur sensiblement toute sa longueur, la carcasse possède des coupes transversales où les espaces accumulés entre les filaments contigus de la couche sont d'au moins 0,03 mm. Au moins un filament de la couche est préformé de façon différente aux autres filaments. La migration du noyau est évitée.

    Abstract: A steel cord for reinforcing a rubber article such as tires, conveyor belts, and high pressure hoses, consists of a plurality of steel filaments twisted in the same twisting direction with the same twisting pitch.
    According to the invention, the filaments are spirally deformed so as substantially not to include any torsional stress or deformation component. This is obtained by means of preformers combined with the use of a tubular twisting machine, comprising filament bobbins mounted in the machine, and whose number corresponds to that of the filaments required for respective layers, including any core of the multiple layer steel cord. By eliminating torsional components acting upon the filaments, the fatigue resistance, adhesion stability and productivity of manufacturing are improved.

    Abstract: Elevator coated ropes or belts are disclosed. The coated rope or belt may include at least one cord and a jacket retaining the at least one cord. The cord may include a plurality of filaments. The filaments are free of second-order helical structure. In a first embodiment, the filaments includes at least one inner filament and a plurality of outer filaments surrounding the at least one inner filament. The outer filaments are bunched together by forming a first- order helical structure through the length of the cord. In a second general embodiment, the filaments are free of both first- and second-order helical structures. The filaments are bunched together by a restraining loop or adhesive at one or more locations along the length of the cord. Methods of making the tension cord are also disclosed.
