Method of making a shape-stranded rope
First Claim
1. A method of making a shape-stranded rope, including:
- providing a core with a sheathing of a deformable material;
twisting round wires into strands by winding these round wires in at least one layer about said core with the sheathing of the deformable material;
subjecting the strand thus formed to plastic drawing until each said round wire acquires a wedge-like profile, said plastic drawing forcing the wires adjoining the sheathing of said core to become partly embedded in this sheathing, and the strand attains a substantially smooth peripheral surface;
following said plastic drawing, compacting the strand thus obtained into a shaped profile, said compacting of the strand into the shaped profile is effected until some of the wires embedded in said sheathing engage said core; and
twisting the strands thus obtained into the rope.

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.

6. A shape-stranded rope comprising
strands of a shaped profile; -
a core of each said strand with a sheathing of a deformable material thereabout, said core including wire members enclosed within said sheathing; wires wound in at least one layer about said core with said sheathing of the deformable material and forming said strand jointly with said core; said wires of each said strand having a wedge-like profile with the narrowing end facing said core, the wires adjoining said sheathing of said core being partly embedded in said sheathing and having points of engagement with said wire members of said core; said wires having straightline portions in cross-section thereof and in said strands owing to their wedge-like cross-sectional shape, engaging one another along helical surfaces and jointly presenting a substantially smooth peripheral surface of the respective strand. - View Dependent Claims (7, 8, 9)
