    Abstract: A metal cord used as a reinforcement for rubber products. The cord includes a strand core composed of a plurality of metal wires stranded with each other. A plurality of metal wires are stranded around the strand core, forming a strand layer. The number of the metal wires which form the strand layer is less than 4 plus the number of the metal wires which form the strand core, and each of the metal wires which form both the strand core and layer has substantially the same diameter.

    Abstract: The present invention relates to the improvement of metal cords for the reinforcement of elastomeric bodies, in particular of vehicle tires which are provided with retaining helixes on their outsides. The problem was to avoid the disadvantageous properties of the retaining helixes in reinforced elastomeric bodies, namely, the impairment of the inherent elasticity of the metal cord and the fretting of the retaining helixes on the outer layer of the metal cord. The problem particularly resided in the improvement of socalled compact cords, meaning cords consisting of layers of identical twisting sense. For the solution of this problem, it is proposed to provide a core strand of shorter twisting pitch (twisting pitch ratio of preferably 1:2 or less) than the twisting pitch of the adjacent outer layer; this in particular in the case of metals cords having more than two layers. For this purpose, the retaining helix can be of a cross section deviating from a circle, in particular of flattened cross section, and consists of metal or of a material whose softening temperature is at least partially lower than or within the cross-linking temperature range of the elastomer to be reinforced; the retaining helix can have the form of a metal/plastics composite or compound body or of a plastics body. The softening portion of the material of the retaining helix is so selected that it is compatible with the elastomer, meaning that no reactions impairing the adhesion between metal cord and elastomer occur between the softening portion of the material of the retaining helix and the elastomer.

    Abstract: A heavy duty pneumatic tire comprises a belt disposed radially outside a carcass and radially inside a tread portion, the belt comprising at least one ply of at least one high-elongation steel cord, the high-elongation steel cord being formed by twisting at least three waving steel filaments together to form a core and a sheath surrounding the core. The waving filaments change place repeatedly along the longitudinal direction of the cord such that one of the filaments forms the core in a portion, but in a different portion of the cord, the same filament forms part of the sheath, thereby defining a plurality of first parts with the core and a plurality of second parts without the core which are disposed alternately in the longitudinal direction of the cord. The elongation at break of the high-elongation steel cord is in the range of from 4 to 10%.
