Abstract
A glass manufacturing system and method are described herein for forming a high quality thin glass sheet. In one embodiment, the glass manufacturing system and method use at least one of a compensated rolling roll, a temperature controlled environment and edge rolls to form a high quality thin glass sheet that has a thickness less than about 2 mm and more preferably less than about 100 μm.
Claims8
A method for manufacturing a glass sheet, said method comprising the steps of:
- rolling molten glass between two rolling rolls to form a glass sheet;
- and
- heating the glass sheet in a temperature controlled environment having a cross temperature gradient located below the two rolling rolls such that a central portion of the glass sheet has a first temperature lower than a second temperature of two outer edges of the glass sheet,
- wherein the temperature controlled environment provides the cross temperature gradient to stretch the glass sheet such that the glass sheet has a substantially constant thickness.
