Abstract
A method is disclosed for heat treating the flutes of a corrugating roll. A laser having a beam with a Gaussian power density distribution is provided for heating the flutes. The beam from the laser is reconfigured by an integrator mirror to form a beam having a homogeneous power density distribution, which is subsequently interrupted by a copper rod to form a substantially U-shaped beam. The beam is positioned over an end of the roll with the open end opposing the center of the corrugating roll, and the roll is traversed relative to the beam, whereby the flute is heat treated.
