Abstract
Official abstract text for this publication.
An apparatus for making a glass sheet using overflow fusion down-draw process comprising an inlet assembly having an elliptic cylindrical section coupled to a transition section which is, in turn, coupled to an open end of an open channel of an isopipe, and an overflow fusion down-draw process for making glass sheet. The glass melt flow has a high surface velocity profile conducive to the formation of a glass ribbon over the surface of the weirs and the wedge side surfaces with the desired mass distribution.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for making a glass sheet by an overflow process using a forming body comprising a trough-shaped part and a wedge-shaped part below the trough-shaped part, the trough-shaped part having a first trough side wall and a second trough side wall over a trough bottom surface defining an open channel having an open end, the open channel having a center plane, the first trough side wall having a first internal trough surface, a first trough top surface and a…
