Abstract
PURPOSE: To prevent the stagnation of an insulating material in an extruder head and enable favorable forming and coating of the material on a core wire with use of only the extrusion pressure by injecting a lubricating agent to around the material (before coated on the core wire) in the extruder.
CONSTITUTION: When an insulating material 17 such as rubber and plastic is extruded through an extruder head 3 to coat a core wire 1, a lubricating agent 18 (e.g. silicone oil) having a boiling point higher than that of the material 17 is injected from an injection pipe 12 to around the material 17. An insulated wire 7 consisting of the core wire 1 coated with the material 18 is passed through an extruding die 5 of which the extrusion rand length is set to be over 100 times the coat thickness. This constitution prevents the stagnation of the material 17 in the head 3, enhances the extrusion pressure, and enables favorable forming and coating of the material 17 on the core wire 1 with use of the extrusion pressure only.
