Abstract
A method for processing a transparent mother sheet includes forming one or more closed contours in the transparent mother sheet that each define a perimeter of a transparent article. Forming each of the one or more closed contours includes directing a pulsed laser beam into the transparent mother sheet to produce defect within the transparent mother sheet and translating the transparent mother sheet and the pulsed laser beam relative to each other thereby laser forming defects along the one or more closed contours. The method further includes separating a portion of the transparent mother sheet along the closed contours, thereby forming one or more transparent articles, where the transparent articles are frictionally engaged with a frame portion of the transparent mother sheet, applying material to a surface the transparent articles, and releasing the transparent articles from frictional engagement with the frame portion.
