ABSTRACT:
The flattened strand rope of the invention comprises wedge-shaped strands, each made up of wires wound on a core. At least a portion of the strand wires are fashioned as twisted wire groups in which the wires are sector-shaped and in contact with each other over helical surfaces. With such a structural embodiment of the flattened strand wire, use can be made of thin and, consequently, stronger and more flexible wires, thereby increasing the strength and flexibility of the rope and making for the use of the rope in the various branches of industry, including lifting mechanisms with large or small drum diameters.
