ABSTRACT:
The disclosed method of manufacturing a multicore cable with insulation, particularly, for sensing elements of communication lines, includes assembling a blank of a cable, deforming the blank of a cable by rolling between two rolls with smooth variation of the degree of reduction over the length of the working stroke from 0 to 90 percent, each successive reduction being conducted at an angle up to 90.degree. relative to the preceding one, and annealing the blank of a cable following each deformation. There are also disclosed two embodiments of the apparatus for performing the method of making a multicore cable, of which the first one is adapted for rolling the blank of a cable from the diameter of 18.0 mm to the diameter of 3.0 mm in two passes, while the other embodiment is adapted for rolling the cable from the diameter of 3.0 mm to the diameter of 1.0 mm in one pass.
