Abstract:
The invention relates to a method and device for detecting flaws in a continuously produced float glass band by checking a glass strip, which extends perpendicularly to the conveying direction and which is observed in transmitted light. The device has the following characteristics: a) the flow of a float glass band is monitored without any gaps by a modularly constructed fastening bridge, scanning sensors fastened to the fastening bridge and two transmission lighting means arranged perpendicular to the glass band, b) each scanning sensor can be oriented by an adjusting apparatus according to the three spatial coordinates in positive and negative directions and can be finely adjusted by a target apparatus that can be pivoted in, in the form of an artificial measurement plane, and c) the lighting means are cooled by a cooling apparatus.
