METHOD OF PRODUCTION OF ROPES AMD DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: rope production.

SUBSTANCE: the invention presents a method and a device for production of ropes with circular, shaped or periodic cross-section. The method of ropes production includes manufacture of wires, the wires twisting in a rope and the twisted rope squeezing by power-driven or idle rollers. Squeezing is made along the axis of the wires or wire-line strands of the outer layer of the rope. At that each roller is permanently squeezing the same wires or strands. Positive allowances between rollers are located in dints between wires or strands of the outer layer of the rope, and a number of wires or strands squeezed by one roller makes from 1 up to n/2 for an even number of wires n and (n-1)/2 for odd n. The device consists of a rope-twisting machine and a roller cage for squeezing of ropes. The roller cage is installed between the drawing out tool and the rotor of the rope-twisting machine and is kinematically connected to the latter for maintaining an equal angular velocity. The rollers of thy cage are located at an angle to the axis of its rotation corresponding to the angle of inclination of the outer surface of the outside wires of the rope to its axis, and the stability of an angular inclination of wires in respect to the rollers is ensured with the form of the grooves made in the rollers. At that the cage includes a device of radial adjustment at the working rope-twisting machine. The method and the device allow to produce the high quality ropes.

EFFECT: the invention ensures production of the high quality ropes.
