Abstract

A process for sheathing a cable core with metal in which the core is immersed in oil in a container and is transferred from the container to the sheath extruder in a siphon tube in which oil flows in a direction opposite to the direction of movement of the core. From the extruder, the metal sheathed core is transferred to a drum and during such transfer the core is subjected to oil under pressure. Prior to inserting the core in the siphon tube, the latter is evacuated and filled with degassed oil. The apparatus comprises a stainless steel siphon tube with one end in the container and the other end connected to the extruder. The siphon tube has a higher intermediate portion to which a piezometric column and a pump are connected and has a coupling adjacent the extruder for supplying degassed oil to the siphon tube.
