  • Apparatus and method for drawing continuous fiber
    Patent number: 6732562
    Abstract: An apparatus and method is disclosed for drawing continuous metallic wire having a first diameter to a metallic fiber having a reduced second diameter. A feed mechanism moves the wire at a first linear velocity. A laser beam heats a region of the wire to an elevated temperature. A draw mechanism draws the heated wire at a second and greater linear velocity for providing a drawn metallic fiber having the reduced second diameter.
