A process for producing flxible cable with multilayer, multi-strand and compact reinforcement is claimed. Metal wires of the same diameter are jointed together in the device which is composed of several jointing mechanisms. At the first jointing mechanism, two or more wires are introduced and jointed, then, go to the next mechanism where more wires in addition are introduced and jointed together. The number of wires can be jointed at each mechanism is determined by the corresponding positions provided at this point. Each new introduced wire should be made in contact with at least two existing metal wires. fed. to several joints, where two or more metal wires are introduced to the first joint, which provids such a characteristic as that the maximum number of wires connecting with the first joint, then introduced to the next, should be determined by the corresponding positions provided by that joint, i.e., each fed metal wire on these positions should be made in contact with at least tw
