  • Patent number: 11292168
    Abstract: It is disclosed a process and an apparatus for manufacturing a figure of eight cable. An extrusion head has separate extrusion dies extruding in parallel a first and second outer sheath around a first and second core, respectively, so as to provide two separate cable elements having respective longitudinal axes laying in a first plane. While the outer sheaths are in a softened state, the cable elements are passed in parallel through a twisting die which causes their longitudinal axes to lay in a second plane forming a predetermined twisting angle with respect to the first plane. This twisting causes the outer sheaths to join together, thereby forming a figure of eight cable.
