Abstract: A method of separating an edge portion from a glass substrate includes applying a scoring tool of a scoring apparatus to a glass substrate to cause the scoring tool to score the glass substrate along a score line as the glass substrate moves relative to the scoring apparatus and applying a breaker bar of a breaker apparatus to the glass substrate as the glass substrate moves relative to the breaker bar to separate an edge portion from the glass substrate along the score line.

Abstract: An apparatus and method for inspecting an edge of a glass sheet are disclosed. The apparatus includes an optical system including a light source arranged to illuminate an edge portion of a glass sheet in a direction oblique to the glass sheet and a camera arranged to take an image of the edge portion, and an image processing device configured to process an image of the glass sheet received from the camera to detect an edge defect of the glass sheet. The method includes acquiring an image of a glass sheet, detecting an edge line of the glass sheet from the image, detecting a reference line from the edge line, and detecting an edge defect of the glass sheet by comparing the edge line and the reference line.
