  • Process for metal wire drawing and a tool for actuating the process
    Patent number: 6449997
    Abstract: In an improved process for drawing metal wires and a tool for actuating the process, a metal wire is coated with a thin surface layer of lubricant and subsequently drawn, gradually in a series of single drawing operations. In a final of the drawing operations, the wire is forced to pass through a hole which exhibits an angle of convergence comprised between 30 degrees and about 85 degrees. As the wire passes through the hole, the layer of lubricant is removed and the drawn wire exiting from the hole is clean and lubricant-free.
