Abstract:
A steel cord for the reinforcement of rubber articles is disclosed, which comprises a central base structure composed of 1 to 4 steel filaments, and at least one coaxial layer composed of plural steel filaments arranged around the central base structure so as to adjoin them to each other, these steel filaments being twisted in the same direction at the same pitch. In the steel cord of this type, the steel filaments constituting the central base structure have the same diameter (dc), while at least one steel filament of the coaxial layer has a diameter (dso) smaller than the diameter (dc) of the steel filament in the central base structure.
Abstract:
A metal cord having a core comprising one or more filaments for the reinforcement of rubber articles comprising a plurality of bundles of grouped filaments wherein the direction of lay of the filaments in the bundles is the same as the direction of lay of the bundles in the cord, each of the filaments having been subjected to plastic torsional deformation, and the average length of lay of each bundle in the cord being substantially equal to the average length of lay of each filament in the bundles, and wherein at any cross-section of the cord the filament or filaments which comprise the core of the cord differ along the length of the cord and belong to the same or different bundles.
Abstract:
The cable includes continuous glass filaments which are helically plied in rovings at a constant helical angle from cable center to outer surface and bonded together in elastomeric material. When heated, thermal elongation of the filaments is opposed by simultaneous radially directed thermal volumetric expansion of the elastomeric material. Thus, with respect to overall cable length, thermal elongation of the cable is opposed by a simultaneous increase in cable cross sectional area such that thermal elongation effects are controllable, dependent upon the thermal expansion properties of the filament and elastomeric materials used, by controlling the helical angle at which the filaments are plied to obtain either expanding, contracting or constant length cables, as desired. Thermal contraction effects produced by cooling the cable also are controllable by controlling the helical angle. In some high tensile load cable applications, the helical angle additionally may be related to tensile load, depending upon the modulus of elasticity of the filaments used. The invention is particularly adapted to helically plied glass fiber cables which are thermally stable over a wide range of temperatures.
