Abstract

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.

Description

technical field [0001] The present invention relates to a method and an apparatus for manufacturing a glass plate molded article by softening a base material composed of a glass plate to form a glass ribbon thinner than the base material. Background technique [0002] Conventionally, glass plates used for substrates of semiconductor devices and displays have been required to have good surface flatness and surface roughness. However, when a thin glass plate is produced by the float method widely used as a current glass plate manufacturing method, in order to form a glass plate suitable for the above-mentioned application, it is preferable to polish the surface of the formed glass plate to improve the thickness of the glass plate. Surface flatness, surface roughness. For this reason, various techniques for improving the precision of grinding glass plates have been proposed. However, in order to improve the grinding precision, unnecessary grinding time and labor are required, ...
