Abstract: 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.

Abstract: An air nozzle for guiding a cut steel strip at the exit from a shearing device for a moving steel sheet is provided. The nozzle is made in one piece and extends along a main plane perpendicular to the direction of movement of the steel strip. The air nozzle includes an air inlet channel with a free end connected to a compressed air generator and an opposite end divided at a deflection junction into a first and a second air discharge channel facing each other on either side of the main plane. The free end of the first air discharge channel is located close to the exit and includes a plurality of first air discharge orifices orientated towards the second air discharge channel. The free end of the second air discharge channel includes a plurality of second air discharge orifices orientated either in the opposite direction to the first air discharge channel or parallel to the main plane so none of the first and second air discharge orifices are orientated in the opposite direction to the direction of movement of the steel sheet.
