Abstract
An endless belt moves a glass sheet having lateral scores along a movement path having a receiving horizontal path portion and a downwardly inclined or sloping path portion. As the leading edge of the glass sheet advances toward the end of the horizontal path section, it moves under a pinch roll. Continued movement of the sheet advances the leading edge under a snap roll spaced above the inclined path portion. The snap roll applies a downward force to the sheet to open a lateral score between the pinch roll and the snap roll. The severed glass drops onto the inclined path portion and is conveyed along the inclined path portion.
