METHODS AND APPARATUS FOR FREE-FORM CUTTING OF FLEXIBLE THIN GLASS

Abstract:

Methods and apparatus provide for: supporting a source glass sheet of 0.3 millimeters (mm) or less in thickness; scoring the glass sheet at an initiation line using a mechanical scoring device; applying a carbon monoxide (CO) laser beam to the glass sheet starting at the initiation line and continuously moving the laser beam relative to the glass sheet along a cutting line to elevate a temperature of the glass sheet to provide stress at the cutting line sufficient to cut the glass; and separating waste glass from the glass sheet to obtain a desired shape.
