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.

Abstract: A glass manufacturing apparatus can include an elongated engagement surface rotatable through a rotation angle between a scoring position and a cleaning position. The glass manufacturing apparatus can further include a scoring device to score the glass substrate when the elongated engagement surface is positioned in the scoring position. The glass manufacturing apparatus can further include a cleaning device to clean the elongated engagement surface when the elongated engagement surface is positioned in the cleaning position. In further embodiments, a method of scoring a glass substrate can include, after producing a score line while the elongated engagement surface is positioned in the scoring position, rotating the elongated engagement surface from the scoring position to a cleaning position. The method can further include cleaning the elongated engagement surface while the elongated engagement surface is positioned in the cleaning position.
