Abstract
Official abstract text for this publication.
In a vertical glass drawing process, an edge guiding assembly ( 33 ) located between a glass forming apparatus ( 41 ) and a glass sheet separating apparatus ( 20 ) reduces horizontal motion of the glass ribbon ( 13 ) from which the glass sheets ( 11 ) are removed and results in the reduction of the difference in stress levels between the top and bottom edges of a glass sheet ( 11 ) made by the process. The edge guiding assembly also provides a reduction of the variation of stress levels between successive sheets of glass made by the vertical drawing process.
First claim
Opening claim text (preview).
We claim: 1. A method for making a sheet of glass by a vertical drawing process comprising: a. forming a glass ribbon using a forming assembly, said ribbon having a central region and two edge regions, each of which has a first side and a second side; b. successively removing sheets of glass from the glass ribbon using a separating assembly; and c. guiding both the first and the second side of each of the ribbon's edge regions with an edge guiding assembly, the edge guiding as…
