Abstract
A multi-stage steel wire drawing machine has, in each stage, two dies and a single drive motor for drawing the wire through the two dies. In a preferred arrangement the dies are mounted side-by-side and an idler wheel used to define part of the wire path between the dies in the stage and a coaxial driven wheel is used to draw the wire through both dies in the stage and to define part of the wire path leading to the next stage. Dry wire lubrication before die entry and water cooling after passage through the dies are disclosed.
