<p>A process for producing a plate glass, characterized in that in the method of continuously forming of glass into a plate, continuously traveling glass before solidification on at least its underside is supported by a gas emitted from a support member and with any gravitational effect on the glass controlled, partial displacement and deformation while shifting the position thereof are repeatedly exerted on the glass so as to achieve propagation over the entirety of the glass and expansion thereof. Thus, there is provided a technology that attains resolution or improvement as to the drawbacks, restraints, etc. of the prior art, being simple and easy, and that markedly alleviates the problems of energy, resources and environment, and that produces a high-quality plate glass with flawless surface. Furthermore, there is provided a new technology that through clarification of important technical aspects and factors in principle and fundamentally lacking in the method making use of vapor films, produces a high-quality plate glass excelling in not only microscopic smoothness but also macroscopic thickness uniformity and planarity, etc. throughout plate glass forming processes utilizing an increased variety of gases.</p> |
