A twisting flyer for a single-twist cable stranding machine, which is adapted to rotate about a rotation axis and includes two shoulders connected by crossmembers, and an articulated structure which has in turns a first carriage provided with elements for translation on first of the crossmembers and which supports a guide pulley for a cable, and a second carriage provided with elements for translation on second of the crossmembers, which supports a counterweight for the guide pulley The twisting flyer further includes a first pair of rods which are hinged with one end thereof to the first carriage and with another end to a second pair of rods which are hinged with one end thereof to the second carriage and with another end to the first pair of rods, balancing weights at hinge regions between the first pair of rods and the second pair of rods.

A machine for manufacturing cables includes a rotor tube inside which is a motor. The machine also includes four rods attached to the tube. The rods are arranged so as to follow secant lines of the wall of the tube and include two mutually parallel plates. Each plate is connected to the four rods. The four rods are arranged such that they exert a force on the wall of the tube towards the inside of the tube in order to compensate for the effect of centrifugal force. The motor is positioned between the plates.

The present invention provides a production method for a closed-loop cable. The method includes the steps of providing a cable including a core and metal strands helically wound around the core, connecting two ends of the cable in splice areas via splice knots formed by ends of each metal strand, inserting the metal strand ends inside the cable after locally removing the core and subsequently overmolding each splice area using a polymer.
