Patent FR-2202854-A1 (FR)
Title: Thickness reduction of fire polished glass sheet - by drawing the hardened core while the outer layers are soft
IPC: C03B18/02
Filed: 1972-10-13
Abstract: The glass sheet is allowed to harden throughout its thickness after leaving the float glass tank and the two faces are then reheated rapidly so that their viscosity is 103.5-105.5 poises while the core remains at >107 poises. The sheet is drawn by rollers rapidly so that the core moves faster than the less viscous outer layers thus producing the required thickness redn. The sheet is then rapidly cooled to harden it and finally passed through a reheating chamber. The process ensures a more uniform initial cooling during drawing since the sheet is exposed to air atmos. on both faces rather than air on one and hot metal on the other.
