Abstract
A method for measuring the sagging of a glass panel in the process of bending the glass panel on a ring mould. The method includes measuring the sagging at a glass panel's measuring point and the measurement data is applied to control progress of the bending process, especially heating of the glass panel or abortion of the bending process. A reference plane stationary with respect to the ring mould is established, a distance gauge is used for measuring a distance between the reference plane and the distance gauge, and a distance gauge is used for measuring a distance between the glass panel's measuring point and the distance gauge. The glass panel's sagging is determined by comparing the distance between the reference plane and the distance gauge to the distance between the glass panel's measuring point and the distance gauge.
