-47- Abstract of the Disclosure This invention is directed to a method and apparatus for forming a glass sheet with differential gas pressure over opposite surfaces thereof. The glass sheet is formed by the action of differential gas pressure over a forming area located on a curved exterior surface of a rotatable glass former. The forming area moves on an arcuate path about an axis of rotation of the glass former. The glass sheet forming operation is carried out in an incremental manner by rotational contact of the forming area of the glass former and the glass sheet being formed. Full dimensional control can be achieved, whereby glass sheets may be produced which are substantially identical copies of one another.
