Cable covered with a solid lubricant

摘要

Application of a lubricant film to extruded cable sheath is carried out at a point downstream from the main extrusion coating and cooling units used to apply the cable sheath. A unit for producing a cable with a sheath coated with a lubricant film comprises an extruder (20) for applying an extruded sheath to a cable core (10), and a cooling unit (21) for cooling the sheathed cable (11). Downstream from the cooling unit (21) the cable passes through a pretreatment unit (22) followed by a deposition chamber (23) where the lubricant film is applied. An Independent claim is included for the process of forming a lubricant coating on extruded cable sheath by using an apparatus as shown.
