THIN SHEET GLASS MANUFACTURING METHOD

摘要

Provided is a thin sheet glass manufacturing method that has: a melting step for melting a glass raw material into a molten glass; a forming step for forming the molten glass into a glass ribbon; a transfer step for transferring the glass ribbon using transfer rollers; and a width-direction cutting step for cutting the glass ribbon in the width direction. When starting manufacture, at least a transfer-direction leading end portion of the glass ribbon is formed, in the forming step, with a thickness with which the glass ribbon can pass on the transfer rollers in the transfer step, and after the transfer-direction leading end portion of the glass ribbon is subjected to the width-direction cutting step, the thickness of the glass ribbon formed in the forming step is changed to a product thickness.
