An optical fibre cable having a strength member has a dielectric sheath estruded over it. When a joint is to be made in the optical fibres or in the strength member which would necessarily result in a bulge in the cable at the point of the joint, this joint is nevertheless drawn through the extruder which has a variable extruder point to accommodate the bulge, whereby a jointed cable can pass through a continuous extrusion process without the need for stopping the extrusion process. Any reinstatement or making good of the dielectric sheath is done after the sheath has been extruded, at the point of the joint. |
