When producing the sheet glass vis-a-vis the glass thickness the device in order to execute the method and the said method in order selectively to exert influence making use of the laser

摘要

This invention, while it was hauled or immediately after the forming in the soft viscosity range, alongside the device which extends over the width of the belt-shaped glass constantly cooling the belt-shaped glass which floats, passes guides, deciding the aim however the said device over the width of the belt-shaped glass, the adjustment possibly heats individually, it regards the method in order selectively to exert influence vis-a-vis the glass thickness when producing the sheet glass. It acquires with sufficiently high resolution temperature profile over width, in order to conform to the small territory of the glass belt-shaped body, although thermal supply is executed locally with laser light, the said laser light it guides this invention, at high frequency over the width of the belt-shaped glass, at that time, it adjusts output of laser light, to the individual thermal supply which decides the aim and it proposes that it modifies. It was hauled or you can obtain, the clear improvement of quality of the belt-shaped glass which floats by selectively exerting influence in this kind of way.
