METHOD FOR MANUFACTURING MOLDED GLASS PLATE, AND DEVICE FOR MANUFACTURING MOLDED GLASS PLATE

摘要

The present invention relates to a method for manufacturing a molded glass plate, including a drawing step for softening and drawing a glass plate preform to a plate width and plate thickness that are less than those of the glass plate preform to mold a glass ribbon, and a cutting step for cutting the glass ribbon in the width direction thereof to form a molded glass plate. The draw ratio, represented by the ratio between the thickness of the glass plate preform and the thickness of the molded glass plate, is from 1.5 to less than 10.
