Abstract

　フロート成形による板ガラスの製造方法であって、ガラスリボン４の成形域Ｆ１を、溶融ガラス３の粘度分布に基づいて溶融ガラス３の流動方向に上流列、中流列、下流列に区画し、かつ少なくとも上流列および下流列において前記ガラスリボンの幅方向に中央部と両側部とに区画し、溶融ガラス３の流動が定常状態において、ガラスリボン４の成形域Ｆ１の上流列の中央部の区画ａ１および下流列の中央部の区画ｃ１のヒータ１１の出力を切るとともに、ガラスリボン４の成形域Ｆ１の区画に対応して天井壁７の上方空間１７が仕切られ、上流列の中央部の区画ａ１または下流列の中央部の区画ｃ１の少なくともいずれか一方の区画に対応する上方空間１７の領域Ａ１、Ｃ１から浴槽内１８に流入する単位面積あたりのガス流量をその両側部の領域の単位面積あたりのガス流量に対して制御する。
