Abstract: A steel cord comprises steel filaments twisted around each other in a first direction about at least one steel core filament having a wave form. The twisted filaments are individually subjected to a rotation about their own axes. This steel cord is formed by deforming the core filament into a planar wave form and twisting the core filament in a second direction to a predetermined degree. The core filaments together with the other filaments are twisted in the first direction so that the twisted filaments are individually subjected to a rotation around their own axes in the first direction.

Abstract: Wires are wound and simultaneously laid directly on the core of the product to form a wound layer between the adjacent wires of which there are peripheral spaces constituting from 15 to 70 percent of the wire diameter. The partly finished twisted wire product made in this manner is subjected to compression so as to cause its plastic deformation in order to obtain the desired shape and size. The wires of the wound layer of the finished product have a contact with the core substantially along the surface thereof as a result of compression applied to the product so as to cause its plastic deformation to produce the desired shape and size.A twisted product made by applying this method has uniform mechanical properties over its whole cross section.
