Beschreibung
Zusammenfassung:	The invention provides a production method for a sheet glass, which comprises an end surface processing step for processing an end surface (ES) of a sheet glass (G) using at least one processing tool(2). The processing tool (2) includes a constant-pressure processing tool which makes contact with the end surface (ES) of the sheet glass (G) at a constant pressure. In the end surface processing step, an abnormal recess and protrusion (UD1, UD2) occurring on the end surface (ES) of the sheet glass (G) is detected, on the basis of positional information of the constant-pressure processing tool (2), by a control device (5) which preforms position control of the constant-pressure processing tool (2). 本发明提供一种板状玻璃的制造方法，该板状玻璃的制造方法包括利用一个以上加工工具(2)对板状玻璃(G)的端面(ES)进行加工的端面加工工序。加工工具(2)包括以固定的压力与板状玻璃(G)的端面(ES)接触的定压式加工工具。在端面加工工序中，通过执行定压式加工工具(2)的位置控制的控制装置(5)，基于定压式加工工具(2)的位置信息，对存在于板状玻璃(G)的端面(ES)的异常凹凸(UD1、UD2)进行检测。
