PROBLEM TO BE SOLVED: To provide a method suitable for continuous manufacturing of a window glass for an automobile with a coating film which is easy to uniformize a thickness of the coating film and a distribution state of thicknesses of each window glass for an automobile with a coating film even when curved shapes of the respective glass base material are varied.SOLUTION: A manufacturing method of a window glass for an automobile with a coating film includes a process of holding a curved glass base material vertically, relatively moving a nozzle for discharging a coating liquid for forming a coating film with respect to the base material laterally on at least a side of an upper side on one main surface of the glass base material, and discharging the coating liquid from the nozzle on the main surface of the glass base material and coating the main surface with the coating liquid. While the glass base material is held vertically, stress is applied on a peripheral edge part of the glass base material and the glass base material is elastically deformed, and an interval between the nozzle and the main surface of each glass base material is adjusted.SELECTED DRAWING: Figure 2
【課題】各ガラス基材の湾曲形状のばらつきがあったとしても、各塗布膜付自動車用窓ガラスの塗布膜の膜厚や、膜厚の分布状態を一定としやすい、塗布膜付自動車用窓ガラスの連続的な生産に適した方法を提供することを課題とする。【解決手段】湾曲形状のガラス基材を上下方向に保持し、前記ガラス基材の一方の主面上の少なくとも上辺側で、塗布膜を形成するための塗布液を吐出するノズルを横方向に基材に対して相対移動させながら、前記ノズルから前記塗布液を前記ガラス基材の主面上に吐出して前記主面上に前記塗布液を塗布する工程を備える、塗布膜付自動車用窓ガラスの生産方法において、前記ガラス基材が上下方向に保持されている間は、ガラス基材の周縁部に応力を加えて弾性変形させて、前記ノズルと各ガラス基材の主面との間隔を調整することを特徴とする、塗布膜付自動車用窓ガラスの生産方法。【選択図】図2
