Apparatus for forming glass sheets with coaxial cavities |
| 摘要 |
A glass ceramic or glass-ceramic sheet is formed by progressively reducing the thickness of the sheet by passing the sheet between successive pairs of counter-rotating rollers. The average viscosity of the sheet is maintained between 5x104 and 109 P during the sheet forming operation.
