The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.

A tubular body that includes a plurality of first wires distributed in an annular portion of the tubular body, and a plurality of deformed second wires alternately disposed between each of the plurality of first wires, the plurality of first wires and the plurality of deformed second wires being in an alternately twisted arrangement in a longitudinal direction of the tubular body, where each of the plurality of first wires has a substantially circular shape in a cross section view, and each of the plurality of deformed second wires has a non-circular shape in the cross section view, has an arcuate side portion that receive a part of a side surface of an adjacent wire of the plurality of first wires, and has an annular sector shape protruding in a radial direction in the cross section view of the tubular body.

Methods and systems for ropes used to catch livestock such as a cattle roping lariat. In one embodiment, the lariat includes a set of strands, each strand including a set of yarns surrounding a central core. The set of strands are twisted to form a twisted rope. The lariat is manufactured using a set of components including a head box, a tree-cross box with a branched strand tree device and a cross device, and a tail box.

A method is provided for manufacturing at least first and second assemblies of M1 filamentary elements and M2 filamentary elements. At least one of the first and second assemblies includes a plurality of filamentary elements wound together in a helix. The method includes a step of assembling M filamentary elements together into a layer of the M filamentary elements around a temporary core, to form a temporary assembly. The method also includes a step of splitting the temporary assembly into at least the first and second assemblies of M1 filamentary elements and M2 filamentary elements.
