Abstract
A process for forming a glass sheet, which is a process for continuously forming a glass sheet, and which comprises a step of introducing a vapor film-forming agent, which is not vapor at least around room temperature and which is vapor at a temperature above the glass transition point of the glass, into a support composed of a structure or a material capable of internally containing liquid, and a step of sliding the support and the glass of which temperature is above the glass transition point against each other via a thin layer of a vaporized vapor film-forming agent.
Claims15
A process for forming a glass sheet, comprising the steps of:
- introducing a vapor film-forming agent in a liquid state, which is not vapor at least around room temperature and which is vapor at a temperature above the glass transition point of the glass, from a reservoir into a support composed of a structure or a material configured to internally contain at least the vapor film-forming agent in a liquid state;
- and
- sliding the glass, which has a temperature above the glass transition point, against the support via a thin layer of a vaporized vapor film forming agent,
- wherein said step of sliding comprises rotating a conveyor belt to which a plurality of the supports is attached, so as to move the plurality of supports at a different speed than the speed of the glass.

- sliding the glass, which has a temperature above the glass transition point, against the support via a thin layer of a vaporized vapor film forming agent;
- and
- adjusting a thickness of the glass by exerting a pressure via a vapor layer from each side of the glass.
