Abstract
A damage-free score is initiated in a moving ribbon of glass by projecting grit material toward the surface of the ribbon in a controlled manner to create a selected zone of surface damage thereon. The selected zone of surface damage is then advanced under a scoring wheel sized, shaped, and loaded to generate the damage-free score upon encountering an appropriate zone of surface damage.
