    Abstract: A sling for industrial lifting made of a load-bearing core and a cover. The cover protects the plurality of yarns that make-up the core. Each core yarn is made of a number of core threads twisted together. The core yarns are twisted together where the twist is in the same direction as the individual core strands and a different direction than the twist of the cover. The present invention describes the method of twisting the core yarns together by inserting core yarns substantially parallel into a cover that has a twist opposite of each core strand. As the core strands are inserted into the cover, the twists of the individual core yarns interact with the twist of the cove, resulting in the core yarns twisting together.

    Abstract: A tire cord having core filaments (10) performed into a helical configuration while maintaining the core filaments (10) in a parallel, side-by-side relationship. The core filaments (10) are not twisted or stranded together. High tensile strength sheath filaments (11) are also performed into a flattened helical configuration so that the sheath filaments (11) can be wrapped around the side-by-side core filaments such that the sheath filaments (11) do not put such tension on the core filaments (10) as to cause the core filaments (10) to bunch. The core filaments (10) are maintained in a flat side-by-side configuration so that no voids are formed and rubber can penetrate into the tire cord. The core filaments (10) may number from three to six and the sheath filaments (11) from one to seven. The cross-section of the tire cord is flattened and confined within an oval-shaped outer bound (21), the oval outer bound (21) being characterized by a major axis and a minor axis. It is desirable that the minor axis be no greater than 60% of the major axis to create the appropriate difference in the bending modulus of the tire cord in the horizontal versus the vertical direction.
