Abstract
A stabilizing system is described herein that reinforces a bowed profile of a downward moving glass sheet which helps to reduce the creation of stress within the glass sheet. In another embodiment, the stabilizing system can also form a rigid zone within the glass sheet which blocks or dampens any disturbances (motion) to the glass sheet that is caused by the scoring and separating of the glass sheet from transferring up the glass sheet. In yet another embodiment, the stabilizing system can also flatten the glass sheet before the scoring and separating of the glass sheet which is desirable because it enables a laser scoring mechanism to cut the glass sheet with the required edge straightness and avoids having to perform another precision cutting process.
