To provide a method and apparatus for wiredrawing a metallic thin line capable of reducing a winding tension while optimizing drawing conditions in the final die and further capable of lowering a surface flaw generated on the surface of the metallic thin line after wiredrawing in the wire drawing of the metallic thin line by a cone type slip model wire drawing machine.
The method for wiredrawing a metallic thin line by the cone type slip model wire drawing machine is characterized in that a pair of capstans 2 and the final die 4 are immersed into a lubricating liquid 9 and the metallic thin line 1 after passing through the final die 4 contacts the pair of capstans 2 to be wound by a winding bobbin. The slip rate between the metallic thin line 1 after passing through the final die 4 and the capstan 2 is so designed to be 5 to 80%. A liquid drop adherent protection cover 10 is provided to prevent the liquid drop 11 of the lubricating liquid that splashes, adhering to a pulley 5 on the way to the wire winding bobbin 7 from the capstan 2 from splashing to the wire winding bobbin 7.
