ABSTRACT:
The disclosed method of making a shape-stranded rope includes twisting large wires into strands by twining them in at least one layer about a core with a sheathing of a soft deformable material, plastic drawing of the strands, forming the strands into a shaped profile and twisting the strands into the rope. The plastic drawing is effected until every round wire of the strand acquires a wedge-like profile, with the wires adjoining the sheathing becoming partly embedded in this sheathing, and the strand acquires a substantially smooth peripheral surface. The method enables, while using round wires, to increase the structural density of the strands, and also to enhance the flexibility, strength and wear resistance of the shape-stranded rope, the rope manufactured by the disclosed method being usable by various industries.
