A hybrid cable having a core and a wrap; the core made from a carbon fiber yarn or bundle of carbon fiber strands or yarns; and the wrap made of a plurality of metal wires helically wrapped around the core, the plurality of metal wires laid side by side without crossing each other. The fibers, yarns, or core may be treated with polymeric sizing, adhesive, or binder. The wire may be steel and may have a coating such as brass or zinc plating, or a polymeric coating or treatment. The hybrid cable is useful for reinforcing composite articles such as belts, track, or hose.

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 multi-strand cord (50) comprises an internal layer (CI) of the cord made up of K=1 two-layer (C1, C3) internal strand (TI), with the internal layer (C1) being made up of Q internal metallic threads (F1), and the external layer (C3) being made up of N external metallic threads (F3), and an external layer (CE) of the cord made up of L>1 two-layer (C1, C3) external strands (TE) wound around the internal layer (CI) of the cord, with the internal layer (C1) being made up of Q internal metallic threads (F1), and the external layer (C3) being made up of N external metallic threads (F3). The cord (50) has an endurance criterion SL40 000 MPa.Math.mm with $SL=\max \left(\frac{{}_{\mathrm{bending\_CI}}}{\mathrm{Cp}};\frac{{}_{\mathrm{bending\_CE}}}{C_r\mathrm{Cp}}\right)$
and a size criterion Ec0.46 with Ec=Sc/Se.

Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.

A multi-strand cord (50) comprises an internal layer (CI) of the cord made up of K=1 three-layer (C1, C2, C3) internal strand (TI), with the internal layer (C1) being made up of Q internal metallic threads (F1), the intermediate layer (C2) being made up of M intermediate metallic threads (F2) and the external layer (C3) being made up of N external metallic threads (F3), and an external layer (CE) of the cord made up of L>1 three-layer (C1, C2, C3) external strands (TE) wound around the internal layer (CI) of the cord, with the internal layer (C1) being made up of Q internal metallic threads (F1), the intermediate layer (C2) being made up of M intermediate metallic threads (F2) and the external layer (C3) being made up of N external metallic threads (F3). The cord (50) has an endurance criterion SL40 000 MPa.Math.mm with $SL=\max \left(\frac{{}_{\mathrm{bending}\_\mathrm{CI}}}{\mathrm{Cp}};\frac{{}_{\mathrm{bending}\_\mathrm{CE}}}{C_r\mathrm{Cp}}\right);$
and a size criterion Ec0.46 with Ec=Sc/Se.
