FIELD: textile, cotton.

SUBSTANCE: this invention refers to the textile industry and concerns the production of the plaited rope. The offered safety and life-saving rope is based on the plaited cord of the spiral plaiting and consists of the supporting core located inside the protecting coat. Protecting coat is made in the form of the sleeving cord. All the wires of the protecting coat plaiting are interwoven and are located along the spiral of one direction simultaneously overlapping two neighbouring wires and after that they are overlapped with the same wires. The basic core is a one-twisted cord with the spin in one direction opposite to the direction of the spirals of the protecting coat plaiting wires. The inclination angle of the twisted core coils equals the inclination angle of the spirals of the protecting coat plaiting wires. The rope is to be used for the kitting-up of the fire fighting, mine-rescue and alpinist equipment.

EFFECT: production of the rope which is more resistant to the abrasion and which is less hard for the bending under its own weight.
